Composite Roofing - Long Lasting Roof
If composite roofing is installed properly, it can be expected to last 30 to 50 years. However, there are various factors that can shorten the life of a composite roof. Below is a list of the factors that can shorten the life of composite roofing.
#1 - Workmanship
You can use the best materials, but if the roof is installed incorrectly, the lifetime of your composite roofing will be shortened. Some roof replacements require changes depending on the old roof being replaced and the new roof replacing the old roof. It is important your roofer is aware of any necessary changes. Roofs are not a 1 size fits all.
#2 - Materials Used

#3 - Roof Accessories
Another important factor that can shorten the lifetime of composite roofing is the quality of the roofing accessories used for the roof. These accessories include vents, pipe boots, perimeter metal, skylights, and more. You can use the best shingles and install them properly, but if low quality accessories are used, problems can arise shortening the lifetime of your roof.

#4 - Ventilation
The attic space needs to be properly ventilated to control the temperature of the roof space. This will keep your composite roof from getting too hot or too moist. Improper venting can shorten the life of your composite roof.
#5 - Proper Roof Maintenance
Keeping your roof clean is important to a full life for a composite roof. Debris, algae, moss, gutters, all need to be cleaned. Inspecting the roof for damage from animals, insects, or missing shingles is also very important. Read our comprehensive guide to composite roof maintenance.
#6 - Local Weather
The severity of the local weather play a factor in the lifetime of your roof. In Seattle, an ample amount of rain creates algae and moss growth. Wind can weaken the shingle seals which can cause missing shingles and or leaks. We install roofs of different types daily. The weather and the roof type will determine the proper installation methods.
