How Does Heat Affect Your Roof In Union County, PA

Do you know how extreme heat can affect the type of roof you have? Roofs are designed to last for many years, but when a rooftop loses its top layer, it can be dangerous, both from a structural perspective and a fire safety standpoint. The hot temperatures in our area can cause the asphalt shingles on your roof to crumble. Are you at risk of heat damage? Learn how to tell if your Union County roof needs repairs.

Signs your roof is subjected to excess heat.

Like the rest of the home, a roof is susceptible to damage from the elements. If a roof has been subjected to excess heat, it could show signs of wear. If you find any of these signs on your roof, you must contact a professional roofer immediately.

Cracked Shingles

If the shingles get too hot, the adhesive that holds this material together can break down, causing cracks to form on the surface. Sometimes these cracks are minor and only become apparent after the shingles have been used for a while. In other cases, they're large enough to be visible right away. Cracks like these can be a sign of improper installation, but they can also point to excessive heat problems.


Asphalt shingles are generally black, gray, or brown, depending on the color of the mineral granules used to cover them. If your roof gets too hot for extended periods, these granules can wear off completely, revealing a lighter-colored substrate underneath. This can signify that your roof is subjected to excess heat; however, it is also possible that discoloration is caused by age or poor ventilation rather than high temperatures.

Shrinking and Blistering

Shrinking and blistering are signs that you need to address immediately. Asphalt shingles are a combination of asphalt and fiberglass material. When exposed to extreme heat, these materials can shrink, causing blisters on the surface of your roof. In some cases, this can cause permanent damage to your roof.

Rotting Shingles

Over time, the sun's intense heat can cause shingles to break down and begin to rot away. A promising sign that this has happened is if you find your shingles are starting to fall apart in your hands when you go outside to clean up after a windy day. If the material is crumbling into dust, this is likely a result of heat damage.

Missing Shingles

You may notice that the shingles near the top of your roof are beginning to blow off in high winds. This is because these shingles have been degraded by UV rays and can no longer hold their position. These shingles may also be more prone to cracking due to heat expansion and contraction. These cracks allow water access to the roof deck and lead to leaks if not repaired promptly.

Thermal Shock

If your roof has been subjected to extreme heat, it may have suffered from thermal shock. This occurs when a rapid temperature change occurs when your roof goes from hot during the day to cold at night. In addition to expanding cracks in your shingles, this can lead to damaged flashing around chimneys or vents.

Weakened Roof

A weakened roof can be caused by thermal shock, where constant fluctuations in temperature cause cracks in the shingles. This can lead to water leaking into your home and causing even more damage. As time goes on, water seeps into the cracks and weakens your entire home's structure. You should look out for cracked shingles and loose or missing nails around the edges of your roof.

Tips to prevent your roof from heat damage.

Your roof is one of the essential parts of your home: It helps to keep you safe from the elements and prevent rain and snow from coming inside. However, it's also one of the most vulnerable parts of your home regarding heat damage. If you want to protect your roof from heat damage, here are some tips.

Inspect your roof for cracks and leaks

This is one of the most important ways to prevent heat damage on your roof. Any small crack in your roof can worsen during the summer months because of the hot temperatures and high humidity levels. You need to ensure no cracks or leaks on your roof, so they don't get bigger over time and become more expensive repairs down the road. 

Trim trees near your home

Trimming trees near your home will help protect your roof from heat damage by letting more sunlight hit the shingles on top of it. The more sunlight that hits these shingles, the less likely they are to absorb any unwanted moisture in warm weather conditions, which can cause water damage over time. 

Light-colored shingles

Shingles that are light in color reflect more of the sun's rays than dark-colored shingles. This helps prevent heat from being absorbed into the roof and transferred into the attic space. If you're considering replacing your roof this summer, consider light-colored shingles as a simple way to prevent heat damage to the shingles themselves.

Adequate ventilation

Heat can also build up in your attic when there's not enough ventilation. Good roof ventilation prevents this built-up heat from harming the shingles on your roof and prevents moisture buildup that could lead to other problems such as mold or mildew growth and dry rot of wood structures.

Coat your roof 

If you don't have the budget for new roofing and have to stick with what you have, consider coating it with a reflective coating instead of painting it all one color—the reflectiveness will reduce how much heat gets absorbed and help keep temperatures down on your roof during hot summer days and nights.

Ensure proper maintenance 

Not maintaining your roof can be very costly in the long run. If a plumbing leak goes undetected, water may seep into the underlayment and cause mold growth, rot, and warping. Hiring professionals for regular inspections will help prevent small leaks from turning into large ones. It’s best to get your roof inspected after every significant weather event.
