Send us Fan Mail Welcome to the first episode of our comprehensive roofing series! In this episode, we dive into steep slope roof coverings - those installed on roofs with slopes of 2:12 or greater. We explore the fundamentals of water-shedding roof systems and examine various roofing materials including asbestos cement shingles, asphalt (fiberglass) shingles, and their proper installation methods...

Send us Fan Mail In this episode, we explore fiber cement roofing - a lighter weight alternative to traditional concrete tiles, clay tiles, slate, and wood shingles. Discover why this innovative roofing material has gained attention in the roofing industry since its introduction around 2000. We'll discuss its weight advantages (325-500 pounds per square), expected service life (25-45 years),...

Send us Fan Mail Metal roofing takes center stage in this episode as we examine both metal shingles and metal panels.
