PVC Roofing Systems: Chemical Resistance, Performance, and Installation Tips
A PVC roofing system is a single ply membrane made of polyvinyl chloride that provides durable, waterproof protection for flat or low slope roofs. It features two PVC layers surrounding a polyester scrim for strength and delivers benefits such as chemical resistance, UV durability, tear resistance, and energy efficient reflectivity. PVC roofing is a long […]
Built-Up Roofing (BUR): Is It Still a Viable System for Low‑Slope Applications?
Yes — Built-Up Roofing (BUR) is still a highly viable system for low-slope applications in 2025. BUR remains one of the most reliable waterproofing solutions for flat and low-slope commercial roofs. Its multi-ply, layered construction creates redundant waterproofing that outperforms many single-ply membranes under ponding water, mechanical loads, and harsh weather. While modern systems like […]
Modified Bitumen Roofing Systems: What Builders Should Know for Small Low-Slope Jobs
A modified bitumen roofing system is a durable, multi-ply asphalt-based membrane engineered for flat and low-slope roofs. It is strengthened with polymers such as APP or SBS to improve flexibility, durability, and temperature resistance. Modified bitumen is installed in rolls and can be torch-applied, cold-adhered, or mechanically fastened, forming a resilient and waterproof roofing assembly […]
TPO vs. EPDM: Choosing the Right Flat Roof System for Durability and Cost
TPO is a durable and reflective membrane ideal for warm climates, especially Florida. EPDM is often cheaper upfront and more flexible, performing best in cold climates. TPO lasts about 15 to 25 years and may cost slightly more initially, but its energy savings and heat resistance help offset the difference. EPDM can last 20 to […]
Fire Ratings for Wood Roof Systems: What Builders Must Know
For wood roof systems, builders must follow exterior fire exposure ratings (Class A, B, or C) established through standardized tests such as UL 790 (ASTM E108). The required rating depends on local code, building occupancy, wildfire exposure, and the specific components in the roof assembly. What is the fire rating of a roof? A roof […]
Wood Shake vs. Wood Shingle Roofing: What’s the Difference and When to Use Each?
Wood shakes are hand split, thicker, and more textured, while wood shingles are machine sawn, thinner, and more uniform. Shakes offer better insulation and a rugged, high-end aesthetic but cost more and require more labor. Shingles provide a smoother, classic look that is easier to install. Use shakes when you want a dramatic, rustic architectural […]
Slate Roofing Systems: High‑End Performance with Structural Tradeoffs
A slate roofing system is a premium, high-performance roof covering that uses individual tiles made from natural, fine-grained metamorphic rock called slate. Known for its exceptional durability and natural elegance, a properly installed slate roof is one of the longest-lasting roofing options available, often lasting anywhere from 75 to 200 years. What Is Slate Roofing? […]
