Whether you have a new asphalt shingle roofing system installed or have an existing one that’s continuing to protect your home from the local weather, it pays to know for sure if it’s been correctly installed. Read on as Roof Masters takes a look at the key features of a well-installed asphalt shingle roof.
A roofing company’s good craftsmanship is evident in the alignment of the shingles. They’re usually laid out in straight lines, both vertically and horizontally. If there are inconsistent overlapping or irregular patterns, it could indicate a rushed job or lack of expertise. Also important is the way the shingles are secured. They should be securely fastened to the roof deck to prevent them from being blown off by strong winds. This typically entails using roofing nails driven straight and flush with the surface of the shingles.
Underlayment acts as a barrier against water infiltration alongside the shingles. A properly installed roof requires an underlayment that is laid flat on the roof sheathing or decking, and entirely covered by the shingles. Roofers usually lay them horizontally, starting from the bottom of the roof, ensuring no wrinkles or bubbles.
Metal flashings should be installed anywhere the roof meets a wall, vent or chimney. They are a crucial component of the roof, responsible for preventing water seepage into the house, especially in these vulnerable areas. Well-installed flashings lie flat against the roof and walls, secured with roofing nails, and are under the protection of shingles to minimize leaks.
Roof ventilation is a crucial component of a well-installed roof. Heat and moisture can build up in the attic without proper ventilation, leading to roof deterioration, condensation and mold growth. There should be enough intake (usually through soffit vents) and exhaust vents (usually ridge vents or turbines) to facilitate consistent airflow in and out of the attic.
The asphalt shingles at the eaves and gables of a roof should overhang slightly. This overhang helps direct runoff into the gutters, preventing water from flowing down the fascia or siding, where it can potentially cause damage.
Drip edges are metal flashings installed at the roof’s edges under the shingles. Its primary function is to direct water away from the fascia and into the gutter. It should be adequately installed and cover the entire length of the roof’s edge.
A well-done roof should look aesthetically pleasing, with clean, straight lines and no visible shingle buckling or curling. Additionally, there should be no exposed nails or leftover debris lying on the roof’s surfaces.
