Roofing 101: When is the Right Time to Replace Your Roof?

Catastrophic weather damage and multiple leaks are two obvious signs that you’re ready for a new roof. But there are other, more subtle indications that you may require the roofing services of a leading Buffalo Grove roofing company like U.S. Exterior by Seidel.


Most roofing experts agree that the lifespan of a “typical” roof is 20 – 25 years. This of course can vary depending on what the roof is made of: metal roofs and concrete roofs usually last longer than an asphalt shingle roof. Another variable is the age of your home – specifically, whether previous roofs were removed, or whether a new roof(s) was installed over an old one. If the latter, then you likely need a new roof. Some of the materials are probably worn away/rotted, and proper ventilation is sorely lacking.


Roof valleys

A “roof valley” is a critical roofing component: these are the areas where water funnels off the roof and into your home’s gutters. Over time, the roofing shingles comprising a valley will fall apart or disintegrating/vanishing due to high winds, age, etc. When this happens, and the valley no longer exists to reappropriate snow and rain, it’s only a matter of time before your roof develops a leak or two.

Light piercing through the roof boards

This issue is usually first detected when a homeowner or contractor is inspecting a home’s roofing for damage and wear/tear. If any part of the roof feels spongy or trampoline-like when it’s walked over, this means the decking beneath the roof is weakened from excess moisture. The next step is to visit your attic and check to see whether light is piercing through the roof boards. Another smart move is to inspect the attic’s insulation for moisture. If either of these issues is present, a new roof is in your future.

Shingle granules in your gutters

Gutters collect lots of different materials. However, if you find that your gutters are becoming increasingly saturated with shingle granules, this is a warning sign that your roof is in disrepair. As a roof ages, its shingles will begin breaking down and shingle granules will filter into your gutter system. Another way to tell if your shingles are falling apart is to contact our Chicagoland roofing contractors and have us inspect your roof for dark patches and inconsistent coloring. These are telltale signs that your roof is close to expiring.

Shingle curling/buckling

As the years pass, there’s a chance that your roof’s shingles will start curling or buckling. One way to confirm this is by looking at the slope of your roof, specifically where direct sunlight falls. This make it easy to see whether your shingles are warping, and to what extent. The more deformation you see, the more likely it is that your shingles and your roof are ripe for replacement. Of course, if shingle curling/buckling is happening on a roof you recently installed (or one that isn’t close to 20 – 25 years old), you could be looking at a defective roof. In this case, contact your roofing contractor immediately.
