Asphalt shingles remain a popular roofing material and a preferred choice for many homeowners because of their versatility, affordability, and ease of installation. However, the true longevity and effectiveness of an asphalt shingle roof are highly dependent on the quality of its installation. In this article, A1 Roofing and Construction cites the critical signs of poor asphalt shingle roofing installation and why working with an experienced roofing contractor is imperative to avoid these issues.
Starter Shingles and Proper Alignment
A crucial step in asphalt roofing is the correct installation of starter shingles at the eaves and rake edges. These shingles serve as the initial line of defense against wind uplift and water infiltration. Proper alignment ensures the overhang is enough for water runoff without making it susceptible to wind damage. If you notice unequal overhangs or shingles that do not align correctly along the eaves or rake, it could indicate a subpar installation.
Nailing Technique Matters
Improper nailing can lead to a host of problems, from blow-offs during strong winds to water damage. Nails should be flush against the shingle—not overdriven or underdriven—and they should be placed in the manufacturer’s designated “common bond” area. Keep an eye out for signs of nails that stick out or shingles that appear sunken—these are red flags for poor workmanship.
Alignment and Pattern Integrity
Asphalt shingles need to be laid out precisely to form a watertight pattern. Shingles should be offset from each other, much like bricks in a wall, to prevent water infiltration. Misaligned shingles are not just an aesthetic issue—they can compromise the integrity of the roof. If your shingle rows look uneven or the pattern seems disrupted, this suggests a potential error during installation.
Flashing is a protective seal that directs water away from critical areas of your roof, such as around chimneys, vents, and where different roof planes meet. Inadequate or absent flashing is a common error in shoddy roofing jobs. Ensuring that flashing is correctly installed can mean the difference between a secure roof and one prone to leaks.
Addressing Installation Mistakes
Inexperienced roofing can result in a roof that is not only unattractive but also vulnerable to extreme weather conditions. To rectify faulty installation, it may be necessary to repair or even replace significant portions of the roof. Working with skilled contractors like A1 Roofing & Construction beforehand can help you avoid these pitfalls and secure your investment.
