New Shingles Seal More Quickly In Hot Weather

How to Felt a Shed Roof – Part 1 Strip Roof Felt & Prep

The good news is that hot weather helps new asphalt-shingle installations lay flat and look good faster than if the shingles were installed in cold weather. New asphalt shingles are often stiff and dont lay perfectly flat when first installed. However, high heat softens the shingles and helps the glue strips on the shingles adhere to the roof surface and create a good seal.

Yet, this quick sealing time has its drawbacks. If the new shingles are placed on compromised felt underlayment, then the shingles may become compromised too. The felt may wrinkle in the heat, and these wrinkles may show up as uneven bumps and ridges, which may permanently distort shingles if they bond quickly to the underlayment.

To avoid wrinkled underlayment and related appearance issues with asphalt shingles, have your roof installed by professionals. It is critical that the felt underlayment be installed flat prior to installation of shingles.

How Heat Damages A Roof

Asphalt shingles have two layers: The bottom layer is made from fiberglass, and the outer layer holds the granules. Granules are small pieces of crushed stone and minerals that give the shingles their color and protect the roof from the suns UV rays. During the manufacturing process, the fiberglass is soaked in asphalt. During this process, its common for pockets of moisture to become trapped inside the asphalt due to temperature and humidity variations inside the factory.

As outdoor temperatures rise, the temperature of the air inside an attic also increases. If the hot air becomes stagnant, the roof and shingles will begin to overheat. The hotter temperatures cause the asphalt to soften, and the moisture pockets within the asphalt begin to expand and blister. As these blisters bubble up, they cause the granules on the outer layer of the shingle to pop off, leaving the materials underneath exposed to direct sunlight and UV rays. Over time, these blisters will continue to expand and begin to impact the effectiveness of the shingles, which leads to a shortened lifespan of the roof, as well as leaks and weather damage.

Heat damage is a serious threat to a roof, but there are several steps you can take to minimize the extent of damage present on the roof, and reduce the risk of more damage occurring in the future.

Plan Ahead For Roofing Work

Roofers are frequently at the mercy of Mother Nature. For homeowners, it is essential to plan your roofing needs ahead of time. This way, you can avoid making emergency repairs or having to complete a reroofing job during the off-season. If you live in a cold climate, and it is approaching winter, its wise to get a fall roof inspection, so youre confident in your roofs condition through the winter. In warm coastal climates, reaching out to a roofing professional before hurricane season is also wise.

Installing The Roof Shingles

You took the time to properly protect your roof against ice and water that tries to drip back underneath your shingles as it is flowing down, and now it is time to put the actual shingles on your home. Begin your shingle installation by laying a row of starter shingles along the lower edge of the roofline and nailing them down using roofing nails. With the starter shingles laid along the very edge of the roof, run a set of starter shingles along the sides of the roof as well, making sure that those rows come down and overlap the starter shingles you laid at the bottom.

Lay your first row of shingles so it overhangs the drip edge by about one inch. Put between four and six nails into each shingle below the tar line but above where the bottom of the next shingle will cross by about ½.

Do this on both sides of your roof and then install ridge cap shingles over top of the ridge. Start at the left side of the ridge and nail the first shingle on the right side. Lay the next cap shingle over the first so it covers that nail and nail it in the same way on the left side. Continue this all the way to the end of the roof. Seal the nail holding the final cap shingle with a bit of roofing tar to help prevent water from getting in.

Should You Change Your Roof To Keep It Cooler

How To Shingle A Roof

Whether you’re building a new structure or repairing an older home, knowing how to shingle a roof can save you a serious investment, and protect your dwelling from the elements.

Step 1 – Prepare Safety

Before getting on the roof, equip a safety harness with a roof hook to prevent you from falling to the ground below. You may not end up needing them, but you’re better off safe than suffering significant injury, or even death.

1.1Sweep the roof deck of all dirt and carefully check the decking carefully so undesired nails, wood pieces, or other obstructions dont end up underneath the underlayment.

Step 2 – Attach Metal Drip Edge

This is a profiled metal strip placed along the bottom of the eave to lead rain and melting snow away from the building, preventing water damage .

2.1Place the drip edge on the edge of the decking boards or sheeting and wrap it around the very edge of the roof.

2.2Slide it in position for a finger to fit in-between the metal drip and the fascia board of the eave. If its too close, suction will be created, leading the water back to the eave .

2.3While maintaining that distance, nail it down starting at one end, every 16-inches or so, right up to the other end of the roof.

2.4If you have to use more than one length for a straight run, overlap the two pieces by at least four inches at the joint and keep nailing as described above.

Step 3 – Attach Ice & Water Shield Membrane

Step 4 – Attach Any Additional Drip Edges

Step 5 – Lay Starter Strips

How Roof Color Influences Home Temperatures

In general, light colors reflect the suns rays, while dark colors absorb the heat. Therefore, lighter color roofs will deflect more heat away from the home and help to keep the interior cooler. The converse is also true the darker the roof, the higher the temperatures are likely to be in your roof or upper floors. As our air conditioners work so diligently throughout the year, even a few degree difference in the attic could make a big impact on our energy costs.

In order to maximize the benefit of a light colored roof, you can choose lighter colored asphalt shingles or tiles, or paint a roof with lighter colored, reflective paint.

Did You Know? According to the Department of Energy, cool roofs roofs designed to minimize heat absorption can lower the temperature in the attic by up to 50 degrees.

Potential Issues During Installation

However, there are issues that GAF-certified roofers have to be wary of when they handle asphalt shingles before or during installation. In very cold weather, for instance, the shingles may become brittle, which means theyre more likely to be overdriven by nails when using regular pressure in the roofing system. If compressed to a certain degree, they could potentially crack or break. They also lose their flexibility and resistance, making them difficult to install. Some shingles may also suffer from what is known as a cold curl in which the edges curl up due to their exposure to frigid temperatures.

When Is The Best Time To Walk On A Roof To Not Damage Shingles

Johanne from Laval, Quebec writes: “Could it be damaging to my new shingle roof to climb up on it in the winter time to install a satellite antenna? If so, what would be the ideal temperature to do work without any damage?”

Aside from slipping on ice, winter is not a bad time to walk on that roof but not the best time.

To illustrate the problem we took three pieces of asphalt shingle and plunged one into a cooler full of ice, left one at roof temperature and put the third under a heat lamp. Then we manipulated each of them to check out two things: what happens if you bend the shingle, and how easy is it to scrape the protective grains off the surface?

A cold shingle is quite brittle. If you must lift a corner, do it ever so gently as while it is cold it can simply snap off. The room temperature shingle has a reasonable flexibility but you can go too far and fracture the fibre even though you may not snap it off, permanently weakening it. When it is truly hot, asphalt shingle are extremely flexible and you can manipulate them safely.

On the other hand, the warmer and more flexible the shingle, the easier it is to scrape off the granules as you walk around.

The moral? When walking on the shingles — do it while they are cooler, cool weather or early in the morning. Manipulating the shingles themselves, do it when it is warmer. Click here for more information on asphalt shingles and the weather.
