Roofing Materials We Specialize In

Asphalt Composition Shingles

Asphalt shingles are the most commonly used roofing material in the Pacific Northwest. They are made of a fiberglass mat base, coated with asphalt, and topped with ceramic granules for added durability, UV protection, and color variety. Available in a wide range of styles and colors, asphalt shingle roofs typically last up to 30 years.

Why it's good for commercial roofs: While asphalt shingles are more common in residential settings, they can be a cost-effective solution for smaller commercial buildings with pitched roofs due to their ease of installation and wide availability.

TPO (Thermoplastic Polyolefin)

TPO is a single-ply membrane system designed for flat or low-slope roofs. Made from a blend of rubber and plastic, it is known for its durability, UV resistance, and cost-effectiveness. TPO is installed with heat-welded seams that form strong, waterproof bonds. With proper maintenance, TPO roofs can last up to 25 years.

Why it's good for commercial roofs: TPO is especially popular for commercial buildings due to its energy-efficient reflective surface, cost-effectiveness, and ability to cover large flat areas efficiently.

PVC (Polyvinyl Chloride)

PVC roofing is another single-ply system used on flat or low-slope roofs. Made from durable plastic and reinforced with polyester or fiberglass, PVC offers excellent waterproofing, chemical and fire resistance, and strong heat-welded seams. It is particularly ideal for commercial buildings exposed to grease or oil. With proper care, PVC roofs typically last 25 years.

Why it's good for commercial roofs: PVC is ideal for restaurants, commercial kitchens, and industrial buildings where exposure to grease, chemicals, or high temperatures is common, due to its superior chemical resistance and fire-retardant properties.

Torch Down (Modified Bitumen Roofing)

Torch down roofing is a popular solution for flat or low-slope roofs, known for its excellent waterproofing, strong UV and heat resistance, flexibility in changing temperatures, puncture resistance, and low maintenance requirements. Repairs are typically quick and straightforward. Torch down roofing can also be used in combination with laminated shingles when certain sections of a home have low-slope areas. White membranes are most commonly used on flat roofs where the roof is not visible from the ground, while colored options are preferred for visible areas or where a more cohesive look with residential asphalt shingles is desired. With proper installation and maintenance, torch down roofs can last up to 20 years.

Why it's good for commercial roofs: Torch down is well-suited for small to mid-sized commercial buildings thanks to its durability, weather resistance, and ease of maintenance and repair.
