The long-term health and performance of an asphalt shingle roofing system hinges on the quality of the installation. Failure to install it per manufacturer specifications will make it unsightly and unable to withstand the elements. The smallest error is enough to shorten the lifespan of the entire system.
As the leading roof replacement company in the area, we make sure not to commit these mistakes whenever we perform asphalt shingle roof installations:
Failure to Use Starter Shingles
Starter shingles installed along the roof’s eaves and rakes protect against water and wind. Many amateur roofers, however, directly install the first course of shingles onto the eave. Without these vital components, water channels can form where the shingles align across the first course. Moisture will eventually find its way into the decking, compromising its structural integrity.
Improper Nailing
Certified roofers make sure the shingles are nailed properly to keep them in place and prevent leaks. Manufacturer guidelines and local building codes specify the number of nails per shingle and the location of each. Strong winds and wind-driven rain can lift improperly-nailed shingles and let moisture into the inner roof layers. Too many or not enough nails can weaken shingle performance, increasing the risk of blow-offs.
Incorrect Shingle Alignment
Each shingle course is laid in a staggered pattern similar to the appearance of a brick wall. A single course must be offset from the shingles below. If installed too high or too low compared to the previous course, the roof will look unattractive. Not only that, but it may not be able to provide a strong seal that protects the entire structure against the wind and water.
