Factors That Effect Roof Cost

The cost of a new roof is determined by a number of factors, including the roof size, roof pitch, roofing materials, and whether or not you have rotted wood underneath your shingles.

Roof Size

The roof size is probably the most important factor when it comes to determining the cost of a new roof. The larger the roof, the more material and labor will be required to complete the project.

Roof Pitch

The roof pitch is the angle of your roof. A higher pitched roof will be more difficult to work on and will require more materials, which will ultimately lead to a higher roofing cost.

Roof Design

The roof design complexity is another important factor that will affect the cost of your new roof. If your roof has a lot of valleys, dormers, or other complications, it will be more difficult to install and will require more materials.

Condition of Your Roof

It's a good practice to routinely inspect your roof for damages. If you catch a problem early it will save you money when it comes time to replace your roof. A roof that is in poor condition may have other issues that will effect the cost of the roof replacement. If your roof has allowed water to infiltrate through the layers, you may have water damage in your attic. If that is the case the roofing company will also have to replace any sections of rotted roof deck.

Type of Roofing Material

The roofing material you choose will have a big impact on the cost of your new roof. Asphalt shingles are the most popular roofing material in NH and they are also the most affordable. With advancement in technology and manufacturing process, asphalt shingles are stronger than ever. Many manufactures are offering Lifetime warranties (50 years) on there shingles. The only caveat being the roof must be installed by a licensed professional who is certified by the manufacturer.  Metal and slate roofs are other types that a present. These types on average have a longer life span than asphalt but are also more expensive to install.
