Poorly installed asphalt shingles can lead to serious damage and compromise the integrity of your home. That is why it’s crucial to be able to identify substandard roofing as early as possible. In this post, we discuss the telltale signs of a poorly executed asphalt shingle roof installation so you can take action before it causes safety or structural issues.
Incorrect Shingle Alignment and Placement
A common issue from shoddy roofing jobs is improper alignment of the shingles. Improper alignment at the eave and rake can lead to water infiltration and wind damage. Correct placement starts with precision in installing the starter shingles. They should slightly overhang at the edge of the eaves to channel water away and protect against water damage and blow-offs. Any deviation may result in the need for emergency roof repair down the road.
Another major red flag is improper nailing. Nails should be flush with the shingle surface and properly spaced according to the manufacturer’s guidelines. Pneumatic nail guns are handy, but incorrect pressure settings can cause nails to be over-driven, under-driven, or placed at incorrect angles. All of these errors can affect the hold of the shingle, making your roof susceptible to wind uplift and leaks.
A complete roofing system is composed of more than just shingles. Certain components like underlayment, ice and water protectors, and drip edges are integral to a roof’s effectiveness. Omitting these can spell disaster for a household, especially during storm seasons. Experienced roofing contractors ensure that every component is properly installed, thereby minimizing the need for repairs down the road.
Gutter and Flashing Flaws
The edges of a roof where gutters are installed and various roof penetrations require proper flashing to prevent water from penetrating the roof system. Issues with gutter installation, such as incorrect slope or placement, and mishaps with chimney, valley, or vent pipe flashings can lead to moisture-related issues in your interiors.
Improperly Installed Valleys
Valleys channel a high volume of water and are vulnerable to leaks if improperly installed. Look for smooth, uniformly applied metal valley flashings free of punctures, rust, or gaps. It’s crucial to ensure valleys are meticulously installed for the longevity and effectiveness of your roof.
What to Do If You Spot Problems
If you believe your roof has been improperly installed, acting promptly to mitigate further issues is imperative. Contacting a dedicated and experienced roofing contractor for a thorough inspection can confirm your concerns and provide options for either repair or replacement, depending on the severity of the installation flaws.
