Sitting at the very top of your home, your house’s shingles serve as the outermost layer of defense for the rest of your home. It’s because of this that healthy shingles are a key part of having a healthy home and should the condition of your shingles be compromised, your roof would be susceptible to a variety of issues. So, if you’re unsure of the condition of your roof shingles, the following are key signs your shingles need replacing.

Sun’s Rays are Visible Through the Roof

If the sun is penetrating your roof, so can moisture. This leaves your roof susceptible to leaks and the development of mold (which if not addressed early on can negatively impact the air quality throughout your home).

Cracking and Blistering Shingles

An obvious concern with cracked shingles is they allow moisture to get to the roof underneath. This can result in roof leaks and cause supporting beams in your roof to begin rotting. Left untreated, roof rot can develop into a sagging roofline and, in time, even a cave-in.

Curling Shingles

If you notice your shingles are beginning to curl away from your roof, this is an issue as they are more vulnerable to being torn off by strong winds and won’t be effective against other adverse weather conditions. Although curling shingles are an issue on their own, they tend to be the result of other issues with your roofing system. For example, poor attic ventilation, incorrectly installed shingle or multi-layered roofs are all problems that can result in curling shingles.

With any form of shingle damage, it’s important to remember there are consequences for the condition of your shingles that go beyond performance. For instance, you’re looking to sell your home, you’re likely to sell your house faster and for a better price if your roof is in good shape.
