If you’ve started researching roof replacement, you’ve probably seen the term “composition roofing” more than once. It’s one of the most popular roofing choices across the country, and for good reason. But what exactly is it, and how does it protect your home? Here’s a clear breakdown for Tallahassee homeowners.
What Is Composition Roofing?
Composition roofing is a type of roofing made from layered materials fused together into individual shingles. The name comes from the “composition” of these materials rather than a single natural substance like wood or clay.
Most people use “composition shingles” and “asphalt shingles” interchangeably. Today’s composition shingles typically have a fiberglass mat core, coated with asphalt for waterproofing and topped with ceramic-coated mineral granules. The result is a durable, affordable and versatile roofing material.
How Is Composition Roofing Made?
Understanding the manufacturing process helps explain why these shingles perform so well:
- Base mat: A fiberglass mat provides strength and structure.
- Asphalt saturation: The mat is coated with asphalt, creating a waterproof barrier.
- Granule layer: Mineral granules are pressed into the surface. They shield the asphalt from UV rays, add color and improve fire resistance.
- Sealant strip: An adhesive strip on each shingle activates in the sun’s heat, bonding shingles together to resist wind uplift.
How Does Composition Roofing Work?
Composition shingles work as an overlapping system. Installers lay them in rows from the bottom edge of the roof upward, with each row covering the top portion of the one below. This overlap sends rain downhill and off the roof instead of letting it seep underneath.
But shingles are only part of the system. A complete roof includes:
- Roof decking: The plywood or OSB base that supports everything.
- Underlayment: A water-resistant layer that acts as backup protection.
- Flashing: Metal pieces sealing joints around chimneys, vents, skylights and valleys.
- Ventilation: Intake and exhaust vents that control attic heat and moisture.
- Drainage: Properly installed gutters that carry water safely away from your roof edge and foundation.
When these components work together, your roof can handle heavy rain, humidity and summer heat.
Types of Composition Shingles
There are two main styles to choose from:
- 3-tab shingles: Flat, uniform and budget-friendly, with a shorter lifespan.
- Architectural (dimensional) shingles: Thicker, multi-layered and more durable, with a textured look that mimics wood shakes or slate. They’re the most popular option today.
Benefits of Composition Roofing
- Affordable: Typically costs less than metal, tile or slate.
- Wide variety: Many colors and styles complement any home design.
- Easy installation and repair: Individual shingles can be replaced without redoing the whole roof.
- Reliable lifespan: With proper care, expect roughly 20–30 years depending on quality and climate.
- Fire resistance: Most carry strong fire ratings.
Is Composition Roofing Good for Tallahassee?
Tallahassee brings intense sun, high humidity, summer thunderstorms and the occasional hurricane or tropical storm. Composition roofing handles these conditions well when you choose wind-rated, algae-resistant shingles and ensure proper installation and ventilation. Algae and moss streaks are common in our humid climate, so algae-resistant granules are worth the small extra investment.
Regular maintenance matters too. Keep debris off the roof, schedule inspections after major storms, and make sure your gutters are clean and flowing so water doesn’t back up under the shingles.

Frequently Asked Questions
Most composition roofs last 20 to 30 years. Architectural shingles typically outlast 3-tab shingles, and lifespan depends on ventilation, installation quality, weather exposure and maintenance.
Essentially, yes. “Composition” refers to the blend of materials, including fiberglass, asphalt and mineral granules, in modern asphalt shingles.
Yes, when you choose wind-rated shingles and have them installed correctly. Many products are rated for high winds, but proper nailing, sealing and flashing are just as important as the shingle itself.
Cost depends on roof size, pitch, shingle grade, and the condition of the decking underneath. Composition is generally one of the most budget-friendly options. A professional inspection gives you an accurate quote.
Look for curling or cracked shingles, missing granules in your gutters, frequent leaks, sagging areas, or a roof approaching 20 years old. A licensed roofer can confirm whether repair or replacement makes sense.
