Composition Shingles Installation
in Sonoma County
Composition shingles, also known as asphalt composition shingles, are used on nearly 80% of the residential roofs in Sonoma County. They’re the most popular roofing material choice because they offer an affordable, durable, and attractive solution for homes of all styles.
The basic construction of the composition shingle is a fiberglass mat at the core with an exterior asphalt coating embedded with crushed rock (colored granules). There are many different styles and grades to choose from. The most widely used are called “architectural” or “dimensional”. All manufacturers offer a limited lifetime warranty. Heritage Roofing can also provide you with an extended warranty upon request.

What are Composition Shingles?
Composition shingles, also called asphalt shingles, are a versatile and cost-effective roofing material made from three primary components: fiberglass, asphalt, and granules.
How Composition Shingles Are Made:
The construction process creates a durable, weather-resistant roofing material:
- Fiberglass Mat Core — The foundation provides strength and flexibility
- Asphalt Layer — Water-resistant coating that binds the shingle together
- Colored Granules — Crushed rock embedded in the asphalt surface adds color, texture, and UV protection
This layered construction makes composition shingles resistant to weather, UV rays, and foot traffic while maintaining affordability.
