Deciding what type of roof, or roof system, you want depends on factors like appearance, materials, your budget, and durability against prevailing weather and climate variables. Some roof systems and materials are ideal for hot, dry weather, while others are better suited to withstand snow, ice, and hail.
Intermountain West Construction can advise you on what roof type best suits your home, business or industrial structure. We are proud to be certified by two leading roofing system manufacturers, CertainTeed and Owens-Corning.
- CertainTeed, as its name implies, is one of the leading manufacturers of multi-layered laminated shingles. Their roofing systems replicate the look of slate, shake shingles and more but with the engineering that means they offer warrantees that last from a minimum of 20 years to an entire lifetime, depending on the type of roofing you select.
A leader in sustainable, green roofing systems, many of the CertainTeed’s products meet the strict guidelines of LEED building for both residential and commercial buildings. Becoming a certified CertainTeed roofer requires completing initial training and ongoing educational courses.
- Owens Corning offers a roofing system with a number of components including a ventilation system, weatherlock sealing, under-laying including structural beams for new construction and the decking, and finally the roofing shingles.
With a large selection of styles and colors, most shingles come with limited lifetime warranty options. Enhance warrantees are available when you have a certified installer like Intermountain West Contractors put on your new roofing system.
Low Slope and Steep Slope
A roof’s slope, or pitch, refers to its vertical rise. Steep slope roofing is seen in residential construction, while low slopes and flat roofs are more common in commercial buildings and industrial parks. Steep slopes are more conducive to water runoff and snowmelt.
Different roofing materials are used for low and steep slopes. Low slope roofs are often made from tar and gravel, metal, PVC sheeting, or polyurethane to protect the building from snow and pooling water. Since they are flat, or nearly flat, appearance is not a concern for most owners of low-slope structures.
Steep slope roofing systems are more complex and can be quite attractive and complementary to the building’s architectural design. Aesthetically pleasing and highly functional, quality roofing on steep slopes is sure to last many years to a lifetime and significantly improve your home’s value.
Types of Steep Slope Roof Systems
Steep slope roofs are generally those with slopes that measure 9.5 degrees or more from the highest point to the lowest. Their coverings can be made from a variety of materials:
- Laminate or asphalt shingles that come in different colors and styles
- Wood shingles made from cedar, redwood, pine, and other wood types
- Clay or concrete tiles that come in different colors and finishes; popular in the Southwest US where Mission and Spanish styles dominate
- Slate that comes in various grades and shades
- Metal panels of various styles and colors
Roofing materials are graded for fire resistance as Class A, B, or C, with A having the highest resistance against fire. This could be a factor in the Intermountain West, particularly for mountain homes where forest fires may threatened homes and businesses.
Metal, laminate, and fiberglass roofing are generally well represented in the Class A category, while organic (wood, clay) shingles are usually rated in Class C.
