fiberglass roof shingles vs. Traditional Asphalt Shingles: Which is Right for Your House?

Choosing the right roofing material is crucial, as choosing the wrong one can pose safety risks. Common roofing materials include metal, wood, PVC, and fiberglass. This blog focuses on fiberglass roof shingles. Fiberglass roof shingles are made of a fiberglass base, an asphalt coating, and a mineral granulate covering. Fiberglass roof shingles, typically a type of asphalt shingle, use fiberglass as the base (mat or backbone) and are combined with asphalt, mineral granules, and fillers/stabilizers.

1. What is the average lifespan of fiberglass roof shingles? Compared to traditional asphalt shingles, metal shingles, or ceramic shingles, which lasts longer?

   
   

The average lifespan of fiberglass roof shingles is approximately 25 years, and with proper maintenance, they can last even longer. In this respect, they outlast traditional asphalt, metal, and PVC roofing.

2. In what climates/environmental conditions do fiberglass shingles perform best? In what areas might they encounter problems? 

First, fiberglass roof shingles perform best at room temperature and in environments with a moderate pH. In low-temperature environments, repeated freeze-thaw cycles, or exposure to ice and snow, fiberglass roof shingles may become brittle and prone to cracking.

3. What are some key precautions or operating techniques during installation and subsequent maintenance? How can I extend the life of my shingles?

This includes roof ventilation, drainage, overlaps, edge sealing, and regular inspections/maintenance.

For example, common maintenance procedures include promptly replacing damaged shingles and removing debris, fallen leaves, and moss.

Success Story: Residential Roof Replacement with Fiberglass Shingles

Client Background

Location: Suburban area in a southern state (relatively warm climate, high humidity, high summer temperatures, moderate winter temperature swings)

House Type: Single-story, single-family residence, roof area approximately 2,200 square feet (approximately 200 square meters)

Original Roof Condition: Existing asphalt shingles, approximately 20 years old, showed significant chipping, warping, and water seepage. The subslab had minor rot, and the gutters and eaves were partially damaged.

High-quality architectural (dimensional) asphalt shingles with a fiberglass base were selected, featuring a thick asphalt layer and a high wind resistance rating, along with a UV-resistant chip shingle overlay. The shingles were painted a dark gray/slate gray to minimize heat absorption and blend with the exterior of the house.
