Though you may think that asphalt shingles are made up entirely of asphalt, they’re actually made from various raw materials. Every manufacturer will have a unique blend of these materials. Most asphalt shingles are made from limestone that has been crushed into an excellent powder. This powder is then mixed with the asphalt to create a filled coating.
- 3-tab: These are the most traditional, basic kind of shingles. They typically have a very flat appearance and generally weigh and cost less than dimensional roofing shingles. However, three-tab shingles are decreasing in popularity and have almost completely disappeared.
- Dimensional/Architectural roofing shingles: Most homeowners prefer these types of shingles because they’re available in various colors, styles, and textures. Additionally, these shingles are typically thicker and offer more protection.
Tile roofs have been used for thousands of years, often lauded for their durability and classic appearance. But why should you choose tiles over something a bit more cost-effective, like asphalt shingles? Roofing tiles are completely made up of recycled materials and are easy to reuse. Some types, like clay tiles, also help circulate hot air, rather than trapping it in and preventing leakage.
Tile roofing is expensive, costing more than double the amount of asphalt, but it will save you money in the long run. Shingle roofs typically need to be fixed or replaced every 15-20 years, but a tile roof can last 50 years or more with little maintenance.
Metal roofing is surging in popularity, with increased demand in the residential market and year after year industry growth. Today’s metal roofs offer streamlined looks and increased energy efficiency, with various options available so you can fit the style of your home’s exterior. So whether you’re building a new home from scratch or updating your existing roof, metal roofing might be the way to go.
Based on a study by the Metal Construction Association (MCA), the life-expectancy of low-slope, unpainted Galvalume® — 55% aluminum-zinc alloy coated steel — steel standing seam metal roofing (SSR) system is 60 years. With the average service life of a commercial building also being 60 years — according to LEED v4 — it’s unlikely a Galvalume metal roof will need replacing.
Modified bitumen cap roofing sheet dates back to 19 century. Developed in 1960s, it is a replacement technology for build-up roofing. The roofing material typically uses BUR technology and adds multiple roof wear layers and cap sheets. These cap sheets include polymer to increase the life span and strength of the material.
