A well-installed shingle roof is crucial for the longevity and protection of your home. At Benson Contracting, located in Glens Falls, NY, we understand the importance of a correctly installed roof. This article delves into the essential aspects of shingle roof installation, ensuring that your investment is sound and your home is secure.

Key Indicators of a Properly Installed Shingle Roof

Uniform Appearance and Alignment

A correctly installed shingle roof should exhibit uniformity in appearance. The shingles should be aligned straight, both horizontally and vertically. Consistent color and pattern across the roof are also indicators of professional installation.

Proper Shingle Overhang

The shingles should extend beyond the roof deck by about 1 to 1.5 inches. This overhang is vital to prevent water from seeping into the roof deck or fascia.

Secure and Flat Shingle Laying

Each shingle should lay flat against the roof surface. There should be no signs of buckling or curling. Additionally, shingles should be securely fastened, typically with four to six nails, depending on the wind zone and manufacturer’s guidelines.

Correct Flashing Installation

Flashing is essential around roof penetrations, valleys, and edges. It should be properly sealed and integrated with the shingles to prevent leaks.

Uniform Exposure and Proper Nailing

The exposure of each shingle (the part visible on the roof) should be uniform. Nails should be driven straight and not visible after installation. They should penetrate the decking to provide adequate hold.

Best Practices for Shingle Roof Installation

Choosing High-Quality Materials

Selecting premium quality shingles and underlayment is crucial. These materials should meet local building codes and be suitable for the specific climate of the area.

Adequate Ventilation

Proper roof ventilation is critical to prevent moisture buildup and extend the life of the roof. This includes a balance between intake and exhaust ventilation components.

Installing Ice and Water Shields

In colder climates, an ice and water shield should be installed at the eaves, valleys, and around roof penetrations to prevent ice dams and water infiltration.

Ensuring Proper Underlayment

The underlayment provides an additional layer of protection against water. It should be installed seamlessly and cover the entire roof deck.
