Asphalt Composite Shingles
The most cost effective sloped roof covering has always been asphalt composition shingles. Available in a wide choice of colors and design appearances to match every style of architecture and every color scheme. Asphalt shingle products maintain their number one position for roofing on residential homes. Asphalt shingles have good sealing characteristicts and adapt well in most environments due to their ability to shed water quickly. The only maintenance is that they be kept clean of debris buildups like a large collection of leaves in the valley troughs, and are occasionally cleaned or treated against mold and algae buildup.
Repairs are easy on shingle roofs. The shingles are sealed to the flashings and can be broken free to be resealed again. A damaged shingle in the field of the roof can be removed with a little careful work and replaced with a new one that should be sealed to all the adjoining shingles. Once shingle roofs are worn out they must be replaced. It is hard to extend the life expectancy for these types of roofs. All asphalt shingles are rated by their weight to establish the expected life span. The 240 pound shingles last from 20 to 25 years depending on design. The 300 to 380 pound shingles last from 28 to 50 years respectively.
Asphalt shingles consist of fiberglass mats that are saturated with asphalts and surface coated with a solid layer of colored ceramic granules. The granules serve not only as a color signature but also as the determining factor for their life expectancy. The sun’s UV radiation robs the shingles of their hydrocarbon oils and the granules reduce that process as long as they remain on the surface of the shingles. As the granules wear away, the shingle mats degrade and begin to allow for water intrusion.
The heavier weighted asphalt shingles naturally have a longer life and are better equipped to withstand the damaging effects of storms. They seal together well enabling a strong ability to withstand the higher forced winds when compared to the lighter weighted asphalt shingles known as 3-tabs. The heavier shingles take on an architectural design to appear typically as wood shingles and when properly installed they will serve well as a good roof.
Stone-Coated Metal Shingles
The new alternative to asphalt composition shingles are stone coated galvalume metal shingles. They are more expensive but will not deteriorate, blow off, or burn as do conventional shngles. They are available in a range of popular colors and offer a Lifetime guarantee. High-end looks. Fire and wind resistance. Steel’s durability and strength. A broad palette of colors. And a weight two-thirds lighter than heavy asphalt roofing. That’s a lot to offer in one roofing product, but the Granite Ridge roofing system pulls it off with style. Though price competitive with upper-end asphalt composition tiles, Granite Ridge outlasts them right down the line.
