Commercial Torch Down Roof Replacement
Torch down roofing — a modified bitumen system — is one of the most commonly used commercial roofing systems for flat or low-slope buildings such as warehouses, retail centers, offices, garages, and light industrial facilities.
Benefits of Torch Down Roof Replacement:
-
Durable, multi-layer waterproof protection
-
Excellent resistance to heavy rain and moisture
-
Strong performance under foot traffic and loading
-
Cost-effective solution for large, flat roof areas

Commercial PVC Membrane Roof Replacement
PVC membrane roofing provides reliable leak resistance and long-lasting performance — especially for flat and low-slope commercial roofs. The heat-welded PVC seams create a watertight barrier against rain, standing water, and moisture infiltration.
Advantages of PVC Membrane Roof Replacement:
-
Superb waterproof protection in Northwest Washington’s wet climate
-
Resilient and flexible membrane for long service life
-
Energy-efficient options available
-
Low maintenance over the life of the roof

Commercial Shingle Roof Replacement
Commercial buildings with sloped roof elements — such as office entrances, overhangs, or pitched sections — may benefit from composition roofing systems. While not as common on large commercial structures, composition roofing can be the right choice when aesthetic appeal and traditional roofing look are desired.
Composition Roof System Replacement Offers:
-
Dependable weather protection for sloped portions
-
Broad selection of colors and styles
-
Enhanced building appearance
-
Long lifespan when installed properly

Why Commercial Roof Replacement Matters in Northwest Washington
Commercial roofing systems protect more than just a building — they safeguard your business operations, employees, customers, equipment, and inventory from the elements. Northwest Washington’s frequent rain, moisture, wind and seasonal weather can accelerate roof deterioration if underlying issues are not addressed promptly, and an aging or failing roof puts your property at risk of water intrusion, structural damage, and costly interruptions.
Investing in a high-quality commercial roof replacement helps ensure superior protection, lower maintenance costs over time, and long-term performance in local climate conditions.
