Extreme weather fluctuations and natural disasters can cause the roofing materials to deteriorate over time. Different circumstances throughout the year can damage your roof and diminish its lifespan.

Roofing experts from Permacoat discuss the five enemies of a roofing system in the brief discussion that follows:


Hail causes dents, bruises, and punctures to the roof. This cracks the shingles and pounds away at the materials covering your roof underlayment. Hailstorm damage leads to shingle deterioration, which can cause leaks.


Condensation occurs when there is insufficient or improper attic ventilation. The moisture in a poorly ventilated attic will build up and can possibly decay the wood components of your roof structure. Make sure to install additional vents to avoid moisture build-up and other problems related to condensation.

Moss and Algae

Moss and algae grow on moist shingles, causing roof rot damage. Once established, the moss roots work their way to the wood deck and roof structure. Algae, on the other hand, create black-green stains and cause rot and deterioration.


High winds can lift up shingles and other roofing materials. This compromises the integrity of the roof and causes extreme damage. It is important to address this immediately to avoid further damage to the structure underneath.

Snow and Ice

Snow and ice can form an ice dam and blocks proper drainage into the gutter. This can cause the water to back up under the shingles and seep into the interior. Gutters may be also filled with ice and detach from the structure.

While a lot of roof damage can be seen from the ground, it is still better to inspect the roof up close. Climb up to your roof to get a clear picture of its overall condition. This will also give you a better idea of what to tell the roofing contractor. Be careful when climbing ladders and avoid inspecting the roof on a rainy day.
