Roofing material costs and installation costs are a deciding factor for some home owners when it comes to choosing roofing materials. Roofing materials vary in price, installation difficulty and price, warranty and life length.
Asphalt Shingles:
Today, asphalt shingles cover more residential roofs than any other material. Every year, 100 million squares are installed in the United States. That's ore than 258 square miles, about the size of Lake Tahoe.
Asphalt shingles' popularity is due to several factors. They're fire resistant and have the most color and textures. They're relatively inexpensive both to purchase and install. An experience Denver roofer can install 15-20 squares a day.
Wood Shakes:
Nothing looks like a wood roof except the real thing (even though roofing manufacturer's have tried a variety of products). Although wood roofs are more expensive materials and to install, many people think they look better.
Wood roofs are composed of either shingles and shakes, there are basic differences that set them apart. Wood shakes are thicker at the butt than shingles. Wood roofs are not only expensive to purchase, they are also more labor intensive to install. Because wood shakes and shingles are nailed onto a roof one at a time, it takes a while to cover a roof with wood. A fast Denver roofer can put on 2-4 squares of wood shakes on in a day.
Metal Roofs:
Metal roofing systems are no longer used for barns and mountain homes. The popularity in using metal roofs has led to manufacturers creating many colors and textures in metal materials. Improvements in both metal-coating processes and in waterproof fasteners have made metal roofing suitable for residential use. The increase in metal roofs being installed in the US is higher than any other roofing materials.
