Planning ahead for a roof replacement project is a good time to consider making changes or upgrades that will offer benefits to the homeowner and their family. If the home's roof is currently protected by older asphalt shingles, upgrading to a newer composition-type roofing system could be an upgrade worthy of consideration. 

Understanding the differences 

Asphalt and composition shingles both utilize asphalt because of its ability to seal out moisture and withstand the severe temperature changes that most roofs must endure. An important difference between older asphalt shingles and newer composition ones involves the layer known as the base mat. The base mat helps to hold the other materials together in a cohesive form to provide protection for the roof. 

In composition shingles, the base mat is formed using ultra-durable inorganic materials, like fiberglass, while the base mat of asphalt shingles is typically made from a less durable organic product, such as wood or paper. While both can provide good initial protection for the home, the composition shingles can offer a much longer usable lifespan because of their base mat makeup and the use of layers of more durable materials.

Understanding the construction

Composition shingles utilize layers of different materials to offer maximum protection for the surfaces of residential and commercial roofs. The fiberglass base mat acts as the structure on which layers are added to create the finished shingle. Many composition shingle roofing systems are made with layers of synthetic resin, topped with asphalt and a thick layer of aggregate granules. This multi-layered construction offers strength and durability, while also preventing moisture from seeping through the surface. 

Composition shingles are available as both 3-tab or more robust shingles known as dimensional, laminate, or architectural shingles. While similar in basic construction, the 3-tab version typically needs to be replaced after just a decade or two of use while the beefier dimensional, laminate or architectural shingle may be expected to many more years of protection, depending on the type and quality of the shingle product installed. 

Understanding the additional benefits 

Homeowners who choose to install a composition roofing system as part of their roof replacement project can also enjoy greater resistance to fire and fewer problems with unsightly algae or mold growth. Replacing the roof of your home is a major home improvement project. To ensure satisfaction, homeowners should begin planning the process well before the work is needed and make time to discuss all aspects of the materials and construction with a reputable roofing contractor in their area.
