FLAT/LOW SLOPE/SHINGLE ROOFING

Flat Roofing

Flat roofing is generally referred to as either vinyl or rubber roofing. PVC roofing (vinyl roofing) is a vinyl coated material.

Vinyl Roofing (PVC)

PVC membrane is begins formation when ethylene and chlorine are combined to produce a vinyl gas. The vinyl gas is converted into a fine powder that is then compounded. During the compounding process additives may be added to increase the durability, flexibility, and colour of the membrane.

PVC roofing comes is a variety of thicknesses. The most common are probably 50 mils, or fifty one-thousands of an inch, or .050", and 60 mils (.060"). Other thicknesses are 40 mil (.040"), 80 mil (.080"), and then there are fleeceback materials (PVC membrane with a fuzzy underside) that go up to 115 mils. They're actually the standard thicknesses (50, 60, and 80 mils) with the fuzzy backing adding to it which makes it thicker.

The strengths and benefits of PVC roofing are:

  • Strong puncture resistant material
  • Superior resistance to chemicals, chemical fumes, greases, acids, oils, and many kinds of fuels
  • UV resistant

Rubber Roofing (EPDM)

One of the longest lasting and versatile roofing materials ever manufactured to withstand exposure to the weather is EPDM. When considering dependability, cost effectiveness, and easy maintenance most experts consider EPDM the most reliable.

EPDM stands for Ethylene Propylene Diene Monomer. Engineering specifications describe EPDM as, "Ideal for outdoor applications because of its excellent resistance to ultra-violet light, ozone, oxidants and severe weather conditions."

Rubber roofing is designed to last 20 years or more. Rubber roofing has high elasticity and tensile strength and is resistant to UV rays from the sun. It holds its flexibility at extremely low temperatures as well.

Low Slope Roofing

Low slope roofing is nearly level and for that reason requires the use of different materials than steeper roofing. For that reason the rolled roofing we use features a granular surface, has the aesthetic look and feel of a shingle roof, but is a three foot wide closed roll and as such can withstand the backup of ice during the winter better than a shingle roof can.

Homeowners building additions such as porches or overhangs often choose low slope roofing because it does not require them to modify the original roof. To build a new roof with the same slope as the old roof would require remodeling the old roof's framing significantly.

Shingle Roofing (Asphalt)

About Shingle Roofing

Shingles styles can be divided into three basic categories: Traditional 3-tab shingles, Architectural shingles, and Designer shingles.

Traditional 3-Tab

The traditional 3-tab design shingle gets its name from the three tabs incorporated into its profile. Always a popular choice, traditional 3-tab shingles are available in a wide variety of colours. Timberline, Chateau and Biltmore are just a few of this type of shingle.

Architectural

The second type is the architectural or laminated shingle. Their remarkable dimensional thickness and deep, blended shadow bands simulate the appearance of classic wood shakes, enhancing the beauty of any home.

Designer Shingles

With a wide array of shingle styles, designer shingles help to personalize the look of your home. Designer shingles include the Royal Victorian, with their old style charm; Quantum shingles, with their thatched roof like appearance; and Interlocking shingles, which are well suited to high-wind regions. The Renaissance is a good designer shingle.
