Top 4 Reasons a Roof Fails

No comments

Let’s face it, roofs do not last forever. In fact, many roofs fail prematurely. First, the problem could seem small and if not taken care of in a timely manner, the problems get worse fast. When this happens, the costs can add up quite quickly. Here we will go over some of the main reasons a roof can fail.

1. Poor Workmanship

Not hiring a qualified contractor is the worst mistake that can be made. You can spend all the money you have on the best materials in the world, but poor workmanship will just end up nullifying everything. Qualified contractors strictly adhere to the manufacturer’s recommended installation procedures. This maintains the full factory warranty.

2. Cutting Corners

This is just the opposite of the above. You can have the best crew working on your roof, but if the materials are cheap, they probably won’t last long. There is a reason why some materials are cheap. It all relates to the old adage, you get what you pay for. Chances are that those low bids you get from certain contractors mean that they are using the cheapest materials available. Always ask about the factory warranty and if they are certified to carry out the warranty.


3. Improper Ventilation

Basically said, roofs need to breathe. It doesn’t matter if you live where it is cold or warm year-round. Ventilation plays a key factor in the lifespan of your roof. This factor is often overlooked by many roofing contractors.

In the winter, one of the most important things to factor in is the ventilation. Ice dams can form fast and damage can seem to happen even faster. When the roof has ice dams, it becomes brittle, cracks and then can leak as the ice defrosts.

In the summer it is just the opposite. Humidity builds up in the attic and then the chances of mold developing are highly increased. This is not only bad for the structure of the roof but can also cause health problems.

4. Flashing

Many people think that the flashing is just ornamental. This is nowhere near true. The flashing is also one of the key elements in the healthiness of a roof. The flashing protects all of the areas that a venerable to seepage. It directs the water away from the interior of the structure. Everything that protrudes through the roof uses flashing. Chimneys, skylights, vents, and valleys are all venerable to leaks.

There are still more factors in why a roof can leak. These are just some of the prime examples of how a roof can fail. Always make sure you hire a qualified contractor. Even small repairs can end up extremely costly in the end. Davis Roofing and Construction can help you with all of your roofing needs.

  Which Type Of Roof Vent Is Best For Your Home?

No comments

Proper ventilation at the roof is important to a complete attic ventilation system as well as to the structural integrity of the roof.  There are two basic categories of roof vents including passive and powered.  A roofing contractor can install four different kinds of roof vents that all fall into one of the two categories.

All roof vents work by allowing outside air that enters the attic through the soffits to escape out the top of the roof, creating attic ventilation that carries away moisture and condensation before it has any chance to damage the structure of the roof, the insulation or the home. In wintertime, without proper ventilation, ice dams can occur.

Below are the four different types of roof vents along with some pros and cons. Your roofing contractor can help you decide which type of vent will work best for your roof and why installing the proper roof vent system can impact the structural integrity of your home over time.

Passive Roof Vents
Low Profile Roof Vents

Low Profile Roof Vents
Low-Profile or Louvered Roof Vent

The most common type of roof vent is probably the low profile roof vent.  Also referred to as “louvered vents” these vents have a low profile and feature a slant-back design to guard against weather infiltration especially in steep-slope applications.  They are often available in either aluminum or galvanized steel and can provide between 50 and 60 square inches of net free area (NFA) per vent. Installation is relatively easy as most include pre-drilled holes for nailing.

Multiple low profile roof vents must be installed on the roof according to the square foot size of the attic. Under 1,000 square feet of attic space requires only 4 vents while a 3000 square foot attic can require as many as 12.

The low profile vent is usually installed on the back roof to minimize any unsightly appearance they may cause. The color of the vent can often be matched to the color of the roof depending on the manufacturer that is chosen.

  Preparing Your Roof for Winter

Preparing Your Roof for Winter

Preparing your roof for winter is something everyone should do, especially for us here in the Chicago area. The leaves are changing colors and the temperature is dropping, it is time to protect your roof before and after winter. We have some steps that we recommend to everyone to get ready for the wintertime.

Winterizing Your Roof

1. Get Your Roof Inspected

Have your roof inspected by a licensed roofing contractor. They not only have the eye for roofing, but they also know what problems are likely to occur and the problem areas. Another reason, if your roof has a steep incline, it could cause a slip accident. Your contractor will advise on what repairs might need to be made so that you can save money in the long run and avoid costly repairs after the winter months.

2. Clean Out the Gutters

Gutters should be cleaned throughout the year regularly. It is even more important during the winter months. Gutters clogged with leaves and other debris could cause improper drainage. This can lead to cracks in the roof because of the expansion and contraction of water as it freezes and melts.

3. Check for Proper Ventilation

Now that we know why it is important to keep the gutters clean, we also need to protect the surrounding areas. The Chicago winds are fierce and having branches rub and cut into the roof is a bad thing. Nearby branches should be trimmed to a couple of feet away and all of the clippings removed from the roof and your property.

4. Clear the Surrounding Area

Attics need proper ventilation in order to function in the right way. If there is not adequate ventilation, the hot air from the sun might cause additional problems. If the hot air cannot escape, the attic can cause some rooms to overheat. This can also lead to the ice and snow on the roof to not melt the way it should. This is what we mean by the water/ice not freezing and melting correctly and causing expansion problems.

At Davis Roofing and Contractors, we are more than happy to come out and give a free estimate to take care of your roof before the winter problems arise. Give us a call and let us worry about your roof during the winter time so that you can enjoy it like you should.

  Three of the Most Common Types of Roofing Material

No comments

There are many types of roofing materials. Everything from asphalt based materials, stone to metal. We are only going to cover the four most common types here.

Many of the roofing materials depend on the pitch (the slope of the roof) of your roof. Some cannot be used depending on the pitch, so make sure you select the proper type for your roof if you plan on doing it yourself. A professional contractor, like Davis Roofing and Construction, can help you make the right choice and also make sure the job is done right.

1. Rolled Roofing Material

Rolled roofing (also known as MSR) is one of the most common types for low sloped roofs and shops and sheds. There are several ways to apply this material, which is what makes it an almost universal material.

This material comes in 100 sqft rolls. This makes it easy to handle compared to shingles or other ceramic/stone. The reason being is the roll usually weighs around 75 pounds.

a. Nail Down

Roofing Nail

Nail down is one of the methods you can choose because it requires a small amount of tools (hammer, cutting knife and tape measure). The only materials you will need are nails, roofing cement and the MSR. It is a fairly simple process, but we will get into that in another blog.

b. Adhesive

A Bitumen adhesive is more common than peel and stick. There is a precise manner that the adhesive needs to be applied. The process is not difficult but can be very messy if not done right. That can also lead to blistering of the material, meaning it will need to be replaced sooner.

c. Torch Down

Torch down still requires nails around the edges to protect from wind damage. The material is still applied in the same fashion. The thing that differentiates from the other methods is that a torch is used to heat the material to activate the adhesive. This causes the material to melt and bond to the roof.

2. Asphalt or Composite Shingles

This is the most popular type of roofing material. Most brands offer 20 to 30-year warranty on its products. It is also easy and inexpensive to repair if you happen to have a shingle break or torn off due to weather damage. Composite shingles also allow for the contraction and expansion of a roof.

3. Standing Seam Metal

Metal roofing was, and still is, one of the most popular for warehouses. Now, with the new processes and coatings, they have been more popular for regular households. There is now a variety of colors to make it easy to match your color scheme for your home. There are two main things that make these roofs stand apart. Flameproof and insect resistant, this leads to a longer lifespan.

  5 Ways to Prevent Roof Damage from Weather

No comments

Even with our modern advances, weather causes billions of dollars of damage from coast to coast. Because roofs help repel that weather, they take a big and costly portion of the damage.

And if you didn’t know, roof damage is insanely expensive to repair.

If you’re looking to spend your money on something other than roof repairs, it’s important you prepare long before the pesky rainy or winter seasons.

To help out we’ve pulled together five tips to prevent seasonal weather taking a toll on your roof. Read on to learn how to save money with a bit of good ol’ prudence, courtesy of the professionals.

Remove Debris From the Roof

Anything lingering on the roof poses a threat. Are there any limbs–big or small–hanging out in a corner or other hard-to-reach place? Leaves, twigs, and moss can spread mold as they decay and, worse, can cause a drainage block.

Water that’s plugged up will pool around these drainage blocks and potentially seep down between the shingles or grooves into your roof. And once water damage happens, you can start pulling out the credit cards.

Remove Dead or Dying Tree Limbs Near the House

How near are we talking? Well, are there any leaning tree limbs hanging over the house? Are there any close enough that could be torn down and tossed through a window during a storm?

Take a walk around your property or take a look up into all the trees around your house. Research how to detect dead or dying trees–looking for signs such as missing bark, lack of leaves in a time of growth, and fungus.

Clean the Gutters

Prepare ahead of storms by cleaning out the gutters (something you should do on occasion anyway). Remove any leaves, twigs, and debris to prevent the stopping up of drains and water seeping into the roof.

Moisture and rot are potential problems for your roof when the gutters are backed up. And consider if there’s rain before suddenly colder weather: all that backed up water will freeze and expand, causing further roof damage.

Fix Damaged Shingles

To avoid having to fix the whole roof, if you see a cracked, bent or broken shingle fix it right away. The roof soaks up a lot of the hot sun rays and can dry out or become damaged by plenty of factors other than storms.

Don’t underestimate the general wear and tear of individual singles, and don’t think that the whole roof will need to be replaced at once. Sometimes just spot treatment is needed for upkeep.

Keep Attic Space Insulated

You’ll want to keep up the insulation under the roof to further prevent any water from seeping in. Also, the insulation is an especially beneficial tool for winter homes that see a large buildup of snow.

If snow isn’t removed or doesn’t naturally blow away, uninsulated attics move hot air upwards and will melt snow, causing more potential leakage.

Prevent Roof Damage with Routine Maintenance

You probably haven’t considered the detriment it would be to lose or have to replace your roof. Apart from being costly and annoying, roof damage is extremely dangerous for anyone beneath it.

You should maintain your roof with consistent upkeep year-round, regardless of the season or threat of a storm.

  5 Things to Know Before Re-roofing Your House

Are you thinking that it’s time to replace your roof? If so, you might be feeling a bit overwhelmed or stressed. After all, it can be as critical as it is costly.

Fortunately, there are several helpful hints to know before reroofing your house. We’re here to break them down for you.

Find the Right Roofer

Some roofers neglect the customer service part of replacing a roof. Since it may only happen once every few decades, they may not see the point in building a strong rapport and trusting relationship.

Furthermore, many roofers undercut their customers by trying to be “the cheapest.” Often, this is a translation for shoddy work!

A reputable roofer will answer all your questions about reroofing. He will be patient and considerate of your needs.

Even if it’s not the lowest price in town, reputable roofers know their market value, and they know how to also work with their customer’s needs. And that’s something worth paying for.

Read all Paperwork

There can be a lot of money and liability that goes into a reroofing job. Save yourself the stress and hassle by checking the following documents:

  • Building permit (if your city requires it)
  • Insurance and liability form
  • Written contract with collaborated details and costs

Make sure that you ask your roofer if you have any questions before signing.

Learn the Materials

Just like with other home remodeling projects, new roofing materials emerge all the time.

There are traditional, asphalt shingles, but there are many other options such as metal, wood, and slate.

Each type comes with its pros and cons. Costs can also vary wildly depending on the material.

Think about the Color

You already know that color is essential for emotions and temperaments. Color also applies to home remodels as well. Shingles come in a large assortment of colors, and it’s crucial for you to think about what will look best for your home.

Ideally, you want the colors to complement your stone, brick, or stucco siding on your home.

As a general rule of thumb: beige or brown homes look great with driftwood or weathered gray shingles. White houses, on the other hand, do well with gray, charcoal, or even black shingles.

Prepare for Noise

There’s no easy way around this: replacing a roof can be very loud. The noise comes from all the scraping off old shingles and hammering and installing new ones.

You may need to temporarily stay at someone else’s home or make accommodations if you’re sensitive to loud sounds.

Final Thoughts on Reroofing

While you may not necessarily be excited about getting a new roof, it’s often essential for the value and safety of your home.

  What is the Average Cost to Replace a Roof in Illinois?

average cost to replace a roof in illinois

Have you been wondering if it is finally time to replace your roof? Is the cost factor of anywhere between 8k and 20k keeping you from starting the process right away?

While a costly investment, maintaining the condition of your roof is important because neglect can lead to leaks, mold, and other structural issues.

If you don’t take the necessary measures at the beginning, you could wind up paying double, even triple, what you would have.

Ready to take the next steps and looking for some more information on the cost to replace a roof? Keep reading to find out more.

Things to Consider About The Cost To Replace A Roof

Many factors influence how much it will cost you to replace your roof. Work closely with your roofing contractor. They will be able to walk you through each step and explain the different costs.


The pitch is also known as the slope of a roof. Steep slopes prevent materials from being stored on the roof while work is being done. This means they typically take longer to complete because roofers will constantly be bringing material up.

When working on steep roofs, roofers will wear extra safety harnesses to protect themselves from dangerous falls. This means steep roofs are almost always more expensive to replace than flat roofs.

These two factors mean that steep roofs are almost always much more expensive to replace than flat roofs or those with minor slopes.

It is important to note that while flat roofs may be cheaper to install, sloped roofs last longer and tend to do better with seasonal weather changes.

Size – Big Factor in the Cost to Replace a Roof

The size of your roof will be the biggest factor driving cost. Roofers tend to charge by the roofing square, which typically refers to a ten by ten-foot space. When planning for the cost to replace a roof, make sure you know the exact size.

Naturally, larger roofs will require more time to complete. This will drive the price upwards, especially if you encounter poor weather and the project gets delayed.

Summers are normally best to replace roofs because there is no fear of snow.


Choosing materials is one way you can control how much your new roof will cost.

  • Asphalt Shingles: This type of shingle is the most popular. They have a low cost, are easy to install, and are long-lasting.
  • Wood Shingles: Wood shingles come in a variety of different woods. Cedar is the most expensive option. Wood shingles are expensive initially but tend to outlast other shingle types. They can last 30-50 years with proper care.
  • Metal Roofs: Metal shingles have become more prevalent. They use recycled material, are durable, and are a very light material. Metal shingles also handle changing weather well.
  • Tiles: Tile shingles are very heavy so they will take longer to install and thus be more expensive. They are fire resistant and can reflect the sun, lowering energy costs.

  How To Choose The Best Roofing Shingles For Your Home

No comments

Roofing Contractors Area

Putting on a new roof can be very stressful when faced with so many options. Whether you are re-roofing your existing home or building a new home from the ground up, choosing the right roof is critical to the end result. This article will explain a few simple ways to selecting the right roof for your home.

What Type Of Shingles Are There?

First, the most popular type of shingle is the asphalt shingle. The asphalt shingle is by far the most common and there are many styles and colors to choose from. If you are living in the midwest, the asphalt shingle provides great protection against the elements and complements the look of the typical midwestern home quite nicely.

Metal, wood and slate roofs are also options, depending on the look you are are trying to achieve. They do each have their pro’s and cons. Metal roofs provide about the best protection against the wind, while real wood and slate shingles create a multidimensional look that is very upscale. The downfall of each of these shingles is they can cost a small fortune both for the product itself and the installation.

The Heavier The Shingle, The Longer It Will Last And Costroofers in arlington heights illinois

With asphalt shingles, you can choose a simple, three-tab shingle or a laminate shingle for a multi-dimensional look. The asphalt shingle consists of a fiberglass layer that is saturated with hot asphalt and embedded with colored granules as it cools. The more asphalt that is used, the heavier the shingle and the longer it will last. That is why some shingles have a 20 year, 25-year or 30 year warranty. The heavier the shingle, the longer the warranty.

Choose Your Color Carefully

To Choose Your Shingle, first think about what color would look best. You will want to complement the color of your siding, brick or stone that is on your home. White homes look great with black, charcoal or gray tone shingles, while beige, brown and tan homes look great with a natural color like burnt sienna, autumn brown, weathered gray or driftwood shingles, to name a few.

It Doesn’t Always Make Sense To Go Upscale

If you stand back from your home and look at your roof and don’t see too much of it, then it may not make sense to spend a lot of money on an expensive shingle when you can’t even see it. If, on the other hand your roof is a very prominent part of your home, then it can be worthwhile to invest in a more decorative laminate shingle.

A good idea is to look at as many pictures as you can of different roofs and try to get the best sense of what would work well on your home.

  The Critical Components Of A Good Roofing System

No comments

A good roofing system incorporates a series of components that work together to protect the home. The shingles are just what you see. Underneath the shingles and at critical areas on the roof different parts of the system combat the many different ways that water can eventually leak into your home.

Components Of A Roofing System

A closer look at this residential roof reveals the critical areas that need extra protection

Roofing System Basics

1. The Roof Ridge Ridge vent on a roof
What Is It? … An intersection of two roof planes forming a horizontal peak.
What Component Does It Require? … A roof ridge shingle that is applied along all roof peaks to allow proper outflow of air from the attic.
2. The Roof Deck roofing system 2
What Is It? … The structural base for the roof, usually made of wood or plywood.
What Component Does It Require? … Most roof decks will have plywood at least 3/8-inch thick. The spacing of the rafters and the pitch of the roof are a factor in the thickness of the plywood required. 3/8″-thick plywood works well with rafters that are 16″ apart with minimal roof loads. The load of the roof varies depending on the pitch of the roof. The flatter the roof, the greater the roof load. Rafters spaced 20″ or more apart require 1/2″ or 5/8″ thick plywood decking. 24″-spaced rafters should have no less than 5/8-inch plywood.
3. Underlayment roofing system 3
What Is It? … A layer of protective material between the deck and the shingles.
Why Is It Necesssary? … The underlayment serves as an extra protective barrier between the roofing shingles and the plywood decking.
4. The Eaves roofing system 4
What Are They? … The lower border of the roof that overhangs the wall.
Why Is It Required? … Insures that rainwater falling on the roof is directed into the gutters and away from the house.
5. Ice and Water Barrier
What Is It? … A self-adhesive waterproofing membrane used along eaves and valleys.
What Does It Do? … Protects areas prone to water leakage against water infiltration from ice damming and wind-driven rain.
6. Metal Drip Edge
What Is It? … A narrow strip of noncorrosive metal used at the rake edge.
What Component Does It Require? … Facilitates water runoff.
7. Flashingroofing system 7
What Is It? … Metal strips applied with waterproofing membrane at junctions of different planes or around protruding surfaces such as chimneys, skylights, and vents.
Why is it necessary? … Provides extra protection at these critical areas where shingles do not extend.
8. The Hip roofing system 8
What Is It? … The intersection of two roof planes that meet to form a sloping ridge running from the peak to the eave.
What Component Does It Require? … Hip ridge shingles that are applied along the hip to create a water-tight seal at the junction.
9. Valleyroofing system 9
What Is It? … The intersection of two sloping roofs joining at an angle to provide water runoff.
What Component Does It Require? … An Ice And Water Shield applied over the underlayment and underneath the shingles to prevent water infiltration due to shingle failure, ice damming and wind-driven rain
10. Undereave Ventroofing system 10
What Are They? … Intake vents located under the eaves of the roof that help draw cool dry air into the attic.
Why Are They Necessary? … Adequate air flow through the attic is critical to remove moisture build up that can ruin insulation and damage the wood framework. Air flows in through the eave vents and upward and out through the ridge or roof vents. Eave vents should always be kept clear inside the attic to allow proper air flow.

  Five Roof Leak Protection Tips For The Winter Months

No comments

It’s winter in the midwest and even though it has been a relatively mild one so far, you still want to make sure your roof is protecting your home from roof leaks when the inevitable rain and snow arrive. If you are not comfortable with climbing up on the roof, you can look through a pair of binoculars for a close visual inspection of your shingles or, you can also have a certified professional come out and do the inspection.

Protecting Your Home From Roof Leaks In Winter

1. Check The Roof Sub Structure To Make Sure It Is Sound


The roof sub structure is the plywood decking material that is placed over the framework of the roof prior to the application of the underlayment and shingles. The wooden decking material can begin to rot if water has leaked under the shingles in the past. Check the plywood decking for signs of warping. If warping has occurred, you will want to get a professional roofing contractor out to make sure the damage is not extensive.

2. Check The Roof’s Flashing Areas

The flashing areas of the roof are located in valleys, around chimneys, skylights and other penetrations such as vent pipes and side walls that join together with a lower roof plane. These areas are the most prone to leaking so you want to make sure the shingles around them do not appear torn, bent, tattered or broken.

The shingles in the valley area shown in this picture are cracked and broken, indicating it is time for a roof replacement.

3. Inspect The Overall Roof and Gutters

Another critical factor in the integrity of your roof is keeping it free from debris both on the shingles and in the gutters. Clogged gutters can cause them to back up and force heavy rainwater up underneath the shingles. Eventually this water will find its way through to the roof decking and into the attic of your home. Inspect the entire roof as well. If you’ve found a pile of leaves in a valley area, these will need to be removed right away to prevent damage.

4. Consider Having Heavy Snow Removed From Your Roof

Getting up on a ladder to remove anything from a roof after a heavy snowfall can be dangerous. It is best to call a professional for help. If snow has really piled up several feet it can be beneficial to remove it from the critical areas mentioned above including in valleys, along roof lines and eaves. Underneath heavy snow melting will occur. The melting snow can turn to ice and back up under the shingles. If snow is especially several feet deep in valley areas, it can be beneficial to remove it.

If you live in a heavy snowfall area, you may want to consider installing electrical wires along the eave edges to help the snow melt off. This is particularly helpful where snow can accumulate more than 2-3 feet or more every winter.

5. Check The Attic For Condensation

Most people forget that your roof can also be inspected from the inside by looking in the attic. Taking a flashlight, see if you can spot heavy condensation, ice or frost on the underside of the roof decking. If this is the case, your roof ventilation is probably not adequate.

Make sure that your attic insulation does not extend over the soffit areas along the inside perimeter of the attic. Soffits provide air intake holes where fresh air is allowed to come up into the attic and ventilate up and outward through the roof vents at the top. When air is stagnated in the attic, the moisture from inside the home does not have a chance to escape and can freeze or cause frost. When melted, it drips onto the insulation. When moisture drips onto the insulation, it reduces its effectiveness and will allow more heat to escape from your home. Your attic should not be any warmer than the temperature outdoors during winter, and this is achieved through proper attic ventilation.
