Asphalt shingle roofs continue to be a popular choice for homeowners due to their durability, affordability and versatility. However, the quality of their installation can affect their weather performance and longevity. In this post, roofing expert Hershey Exteriors shares the hallmarks of a skillfully installed asphalt shingle roof.
Straight and Uniform Alignment
One of the first things to look for when assessing the quality of a shingle roof installation is the alignment of the shingles. They should be straight and uniformly placed, following a precise pattern. Misaligned shingles can lead to noticeable gaps or unnecessary overlaps, which can compromise the roof’s ability to protect against water intrusion.
Proper Shingle Overlap
This is an integral part of a typical asphalt shingle roof installation, as it ensures there are no gaps through which water can seep into the house. Each shingle should overlap the one below it properly. Also, the joints between them should be staggered to prevent leakage. The overlap amount depends on the type of shingle and the roof’s slope.
Secure Attachment of Shingles
The shingles of a typical roof, which isn’t always applicable to flat/low slope roofing, should be properly nailed down based on the type and the manufacturer’s instructions. Nails should penetrate the shingle without breaking through its surface. This ensures the shingle is securely attached and can withstand strong winds and severe weather conditions. Overdriving or underdriving the nails can lead to shingle damage and premature roof failure.
Correct Flashing
Flashing prevents water from penetrating a structure at any point where the roofing material is interrupted or joined. This includes areas such as valleys, vents, chimneys and skylights. When installed correctly, flashing forms a watertight seal that prevents leaks and water damage. It should be securely fastened and sealed with a roofing sealant for optimal performance.
Adequate Underlayment
The underlayment is a protective barrier between the shingles and the roof deck. It provides additional protection against water intrusion. A quality underlayment is crucial for the longevity of your roof. It should be flat and wrinkle-free to prevent buckling of the shingles.
Proper Ventilation
A properly installed asphalt shingle roof will have efficient and correctly placed roof vents. Proper ventilation prevents heat and moisture buildup in the attic, which can lead to roof decay and mold growth. Roof vents should be strategically placed for maximum airflow and sealed to prevent leaks.
Clean and Tidy Workmanship
An essential characteristic of a well-installed asphalt shingle roof is clean and tidy workmanship. A professional roofer will also ensure that there is no leftover debris or materials on the roof or around your property after the installation. This level of cleanliness not only enhances the aesthetic appeal of your roof but also prevents any potential damage caused by leftover debris.
