You can't beat the reliable service and top-quality materials you'll receive from Norwest Roofing. For over 20 years weâ€™ve specialized in all types of commercial roofing work, from new construction, to patching leaks and more. Our commercial roofing service can be tailored to suit all types of business and industrial roofs, including:
Foam is sprayed directly onto the roof and solidifies before a protective coating is applied.
Because of its flexibility, foam is especially useful for roofs with unusual shapes or configurations. Foam has a number of
unique advantages over other types of flat roofing systems. For one, it protects against thermal shock and it can
reduce your air conditioning bills.
Built-up roofing or "hot tar roofing" is a time-tested method.
Built up roofs must be protected from weather, sunlight and foot traffic by some kind of surfacing material such as gravel,
a mineral granule covered top layer (a cap sheet), a smooth coat of hot asphalt or a special reflective coating.
Modified bitumen is made of reinforced asphalt impregnated felts. The asphalt in the felts is modified with
plastic or rubber polymers to improve its overall performance. They can be glued to the roof with hot asphalt or an adhesive, or by using propane
torches to melt the asphalt underside.
Single ply membranes are made of rubber, plastic or a hybrid of the two. As the name implies, single ply membranes
are applied in a single layer.
SLOPED ROOF SOLUTIONS
Shingle roofs are reinforced with organic or fiberglass materials. Although asphalt shingles reinforced with organic felts have
been around much longer, fiberglass-reinforced products now dominate the industry.
Clay or concrete tile is a durable roofing material. Mission and Spanish-style round-topped tiles are used widely
in the Southwest. Flat styles are also available to create a French or English look. If you are replacing another type of
roof system with tile, you will need to verify that the structure can support the load.
These shingles own an overwhelming share of the steep-slope roofing market and can be reinforced with organic or
fiberglass materials. Although asphalt shingles reinforced with organic felts have been around much longer, fiberglass-reinforced
products now dominate the market.
These are made up of a fiberglass mat, top-and-bottom layers of asphalt and mineral granules.
Fire Resistance Ratings
An asphalt shingle's ability to resist fires is categorized by Class A, B or C. Class
A signifies the most fire-resistant. Classes B and C are less fire resistance. Most fiberglass shingles have
Class A fire ratings while the majority of organic shingles are rated Class C.
Organic and fiberglass products are available in laminated
(architectural) grades that offer a textured appearance. Zinc or copper-coated ceramic granules also can be applied to
organic or fiberglass products to protect against algae attack. Regardless of their reinforcing type and appearance,
asphalt shinglesâ€™ physical characteristics vary significantly.
