Asphalt roofs are one of the most favored and common roofing solutions in the United States. They’re affordable, durable, and easy to maintain. However, a few issues often pop up with asphalt roofs.
In this blog post, we’ll go over the most common of these issues and provide you with some tips on remedying them. So, if you’re curious about asphalt roofs or have been experiencing some problems with your current one, read on!
Blistering – The Wrath of the Sun
Blistering is a common issue associated with asphalt roofs. It occurs when moisture becomes trapped between layers of the roofing material and expands in the heat, causing the roof’s surface to bubble up.
Blistering exposes your roof, decking, and home to the elements, resulting in leaking and early roof system failure. That is why it’s critical to deal with any blistering locations as soon as possible.
To prevent blistering, make sure your roof is adequately ventilated and that there is no trapped moisture. You can also apply a cool roof coating to reflect the sun’s heat away from the roof’s surface.
Curling – Nearing the End of Its Lifespan
Asphalt roofing will eventually reach the end of its lifespan. Curling shingles will indicate that it’s time to replace your roof.
Curling happens when the asphalt loses its flexibility and can no longer withstand the expansion and contraction of temperature changes. The shingles will start to buckle and form a wave-like shape.
Another factor that causes curling is the misalignment of the felt layer underneath the shingles. It can happen if the roof is not installed correctly or if the decking has warped over time.
Cracking – Ventilation Issues
Shingles will inevitably crack as they age. Wind, roof loads, thermal movement, and deck motion contribute towards shingle cracking over time. If your roof is older and some surface cracks do not completely split or rip through the shingles, it’s almost certainly because the shingles are older.
Look for any early cracking on a newer shingle roof, which might indicate a problem during installation. It might be caused by a manufacturer defect in the product, insufficient ventilation for the roof system, or something else.
Finally, and perhaps most important of all, if you have damaged shingles on your roof, they need to be replaced right away. If left unattended, this can cause the water-tightness of the roof to be jeopardized.
Granule Loss – The Not so Fine Print
Asphalt roofs are covered with tiny ceramic granules. These act as a barrier from the sun’s UV rays and give the shingles their color and texture. Over time, these granules can wear down and fall off the shingles.
When this happens, the asphalt is exposed to the elements and will start to deteriorate. It will cause the shingles to become brittle and cracked. If you notice any granules in your gutters, it’s time to call a roofing contractor.
They will inspect your roof and guide you accordingly about what you should do.
