5 Frequently Asked Questions About CertainTeed Shingles
1. Are CertainTeed shingles better than GAF?
Both CertainTeed and GAF are top-tier roofing brands, but CertainTeed shingles are often preferred for their heavier construction, superior granule adhesion, and broader selection of premium designs. CertainTeed is widely regarded for its luxury and designer shingles, while GAF is often chosen for its affordability. At Thermo-Seal, we install both and can help you choose based on your specific goals.
2. How long do CertainTeed shingles last?
When properly installed and maintained, CertainTeed shingles can last 30 to 50 years, depending on the product line. Architectural and designer shingles like Landmark Pro or Grand Manor offer enhanced durability and weather resistance, giving you long-term performance and beauty.
3. What styles of CertainTeed shingles are available?
CertainTeed offers a variety of shingles, including 3-tab, architectural (dimensional), and luxury lines. Popular options include Landmark®, Landmark Pro®, Highland Slate®, Grand Manor®, and Presidential Shake®. Each line offers unique aesthetics and features to suit different homes and budgets.
4. Do CertainTeed shingles come with a warranty?
Yes, CertainTeed provides robust warranty options, including limited lifetime warranties on many of their architectural shingles. When installed by a certified contractor like Thermo-Seal, you may also qualify for extended warranty coverage with added protections on workmanship and system components.
5. Can CertainTeed shingles improve my home's energy efficiency?
Yes. CertainTeed shingles with reflective granule technology can reduce roof surface temperatures and help lower cooling costs in the summer. Combined with proper attic ventilation and underlayment, a new CertainTeed roof installed by Thermo-Seal contributes to a more energy-efficient home year-round.

CLIENT REVIEWS
What Our Clients Are Saying About Us
Thermo-seal Windows provides exceptional customer service alongside high-quality products. Recently, I had the majority of my home's windows replaced by Aaron's team, and their performance was nothing short of impressive. They arrived on time, maintained a tidy work area, and dedicated themselves to ensuring a perfect installation of the windows.
Aaron and his team were amazing, from start to finish! They worked with us every step of the way and Aaron was always just a call or text away to answer any questions we had. The windows are perfect and we love them. We highly recommend working with Aaron and his team. They are professional, courteous and their work is top notch!
