Shingle Roofs
Shingle roofs are the most common residential roofing system in the U.S., and they’re especially popular in South Florida for their affordability, flexibility, and ease of installation. This guide provides an in-depth look at how shingle roofs are made, how they function, and why they remain a popular choice for homeowners.
What Are Shingles Made Of?
Most asphalt shingles are made using a fiberglass mat coated in asphalt, which is then covered with ceramic-coated mineral granules. The fiberglass provides strength, the asphalt gives waterproofing ability, and the granules add UV protection and color. These shingles are manufactured in large rolls and cut into tabs or architectural profiles depending on style.
How Shingles Work with the Roofing System
Shingles are designed to shed water — not block it entirely. That’s why they are layered in an overlapping pattern. They work in conjunction with the underlayment beneath them, which acts as the true waterproof barrier. If wind-driven rain gets under the shingles (which is common during storms), the underlayment is what stops it from reaching the wood deck.
Types of Asphalt Shingles
- 3-Tab Shingles: Traditional flat shingles with uniform size and shape. More affordable but less durable.
- Architectural (Dimensional) Shingles: Thicker, laminated shingles with a layered look. These are more durable and are the current industry standard.
- Premium/Designer Shingles: High-end styles that mimic slate or shake, offering added curb appeal and strength.
Advantages of Shingle Roofs
- Cost-Effective: Lower material and labor costs compared to tile or metal.
- Fast Installation: Can often be completed in 1-2 days depending on home size.
- Lightweight: No additional structural reinforcement is typically needed.
- Variety of Colors: Available in a wide range of shades to match your home.
- Wind Ratings: Many architectural shingles are rated for up to 130 mph when installed with a high-wind nailing pattern.
- Easy to Repair: Individual shingles can be replaced without redoing the whole roof.
How Shingle Roofs Are Installed
- Tear-off: Remove existing shingles and inspect/repair the wood deck.
- Underlayment: Install synthetic or peel-and-stick underlayment over the deck.
- Flashings: Add drip edge and flashing at valleys, chimneys, and roof penetrations.
- Starter Strip: Install starter shingles at the eaves and rakes to anchor the system.
- Shingle Application: Lay shingles in a staggered, overlapping pattern from bottom to top.
- Ridge Vent & Ridge Cap: Install ridge vent for attic ventilation and ridge caps to seal the roof peak.
- Final Inspection: Check fastening, alignment, sealant, and clean-up.
Shingle Roof Lifespan & Maintenance
Architectural shingles typically last 20–30 years in Florida when installed and maintained properly. Regular inspections, cleaning debris from valleys, and checking for lifted tabs can help extend the life of your roof. Storm damage should always be assessed quickly to prevent leaks.
