Roofmax is qualified and dependable in both residential and commercial roofing systems. Below are some terms and explanations that you should know when figuring out what type of roof work you want.
STEEP SLOPE
A roof with a steep slope is harder for someone to walk on. Steep slopes will have quicker run offs of water, a stray ball, etc. The slope is determined by the ratio between how many feet the roof rises to how many feet the roof spans. This figure determines a slope. A slope of 2:12 and higher is considered a steep slope.
LOW SLOPE:
A roof with a low slope is easier for someone to walk on. Low slopes will have slower run offs to water, a stray ball, etc. Low slope roofs can be moderately to extremely flat, sometimes even completely flat. In this case, the roof has no slope. A slope of 2:13 and lower is considered a low slope.
METAL SHINGLES/PANELS:
Primarily thought of as a low-slope roofing material, this material has been found to be a roofing alternative for home and building owners with steep-slope roofs. There are two types of metal roofing products: panels and shingles. Numerous metal panel shapes and configurations exist. Metal shingles typically are intended to simulate traditional roof coverings, such as wood shakes, shingles and tile. Apart from metal roofing’s longevity, metal shingles are relatively lightweight, have a greater resistance to adverse weather and can be aesthetically pleasing. Some have Class A fire ratings.
SLATE SHINGLES:
Quarried in the United States in Vermont, New York, Pennsylvania and Virginia, this roofing material is available in different colors and grades, depending on its origin. Considered virtually indestructible, it is, however, more expensive than other roofing materials. In addition, its application requires special skill and experience. Many older homes, especially in the Northeast, are still protected by this long-lasting roofing material.
CONCRETE AND CLAY TILES:
These tiles are a durable roofing material. Mission and Spanish-style round-topped tiles are used widely in the Southwest and Florida, and flat styles also are available to create French and English looks. Tile is available in a variety of colors and finishes. Tile is heavy. If you are replacing another type of roof system with tile, you will need to verify that the structure can support the load.
SHAKE SHINGLES:
This roofing material is made from cedar, redwood, southern pine and other woods. Their natural look is popular in California, the Northwest and parts of the Midwest. Shakes are handmade and rougher looking than other roofing materials. A point to consider: Some local building codes limit the use of shakes because of concerns about fire resistance. Many shakes only have Class C fire ratings or no ratings at all. However, Class A fire ratings are available for shake products that incorporate a factory-applied, fire-resistant treatment.
COMPOSITION (ASPHALT) SHINGLES:
This roofing material possess an overwhelming share of the U.S. steep-slope roofing market and can be reinforced with organic or fiberglass materials. Although composition shingles reinforced with organic felts have been around much longer, fiberglass-reinforced products now dominate the market.
Organic shingles consist of a cellulose-fiber (i.e., wood) base that is saturated with asphalt and coated with colored mineral granules.
Fiberglass shingles consist of a fiberglass mat, top-and-bottom layers of asphalt, and mineral granules.
Composition shingles’ fire resistances, like most other roofing materials, are categorized by Class A, B or C. Class A signifies the most fire-resistant; Classes B and C denote less fire resistance. Generally, most fiberglass shingles have Class A fire ratings, and most organic shingles have Class C ratings.
