A composition roof is one of the most popular roofing systems used in residential homes today. Known for its affordability, durability, and versatility, it has become a top choice for homeowners looking for a long-lasting roofing solution without the high cost of premium materials like slate or metal.
In this SEO-optimized guide, we will explore everything you need to know about composition roofing, including its materials, advantages, disadvantages, installation process, and maintenance tips.
What is a Composition Roof?
A composition roof (also known as an asphalt shingle roof) is made from a mixture of materials such as:
Fiberglass base
Asphalt coating
Mineral granules
These materials are combined to create shingles that are layered on a roof deck to provide protection from weather conditions like rain, snow, wind, and sunlight.
Because of its layered construction and composite materials, it is called a composition roof.
