Some roof repair problems are a result of mistakes with shingle installation. This is why homeowners are discouraged from DIY or unprofessional roof installation. Here are some shingle installation mistakes that can lead to severe problems.

Lack of Starter Shingles

Starter shingles help with wind and water protection at the eave and rake. The starter shingle seals with the shingle at the first course to prevent wind and water from penetrating under the shingle along the eave and rake.

Starter shingles should be installed so they slightly overhang the edge of the eaves. This allows water to run off. A course of shingles should be installed over the starter shingles to form a strong defense against water damage and blow-offs.

When a roofer installs the first course of shingles directly on the eave, water channels will form, and moisture will spread to the roof deck. Therefore, ensure your roofer uses starter shingles when installing a new roof. 

Missing Components

Another shingle installation mistake is leaving out essential roofing components. One of the most overlooked roofing components is the drip edge. This is the roof's edge flashing. A drip edge prevents water at the roof's edge from moving into your house.

It is also essential to install leak barriers. These are waterproofing materials. Many roofers forget leak barriers and move forward to installing the underlayment. Neglecting to install these components may not have immediate consequences. However, if the outer roofing layer fails, the lack of these components can cause serious water damage.

Improper Nailing

Roofing contractors follow local building codes when fastening shingles to the roof deck. These instructions specify how many nails should be used per shingle and the location of the nails. This is the reason DIY shingle installation often leads to improper nailing.

Nailing new shingles correctly prevents leaks that can cause early roof deterioration. Over time, your shingles will blow off. To avoid this problem, contract a professional roofer for a new roof installation.

Improper Shingle Alignment

It doesn't matter whether you install your shingles vertically or horizontally, they should be precisely aligned. Improper alignment affects the roof's exposure to the elements. Additionally, the wrong alignment will impact the aesthetics of your home. Also, the alignment of your shingles affects their seal strength and wind performance. One of the signs of improper alignment is the wavy appearance of shingles.

In Closing

When embarking on a new roof installation project, ensure you enlist professional services. Compare the quotes and the quality of services for different contractors before making your choice. Hiring a roofing contractor will help you avoid the cost and inconvenience of shingle installation mistakes.
