Services
Roofing Services
Clow Roofing provides comprehensive residential and commercial roofing solutions using premium composition shingles with enhanced nailing pads for superior adhesion. Our installations feature heavy-gauge pre-painted metal flashing at valleys and leak-prone areas, ensuring lasting protection against Pacific Northwest weather. We offer multiple roofing styles including cold process systems, with seamless integration of skylights and ventilation components.
Siding Installation
We specialize in cedar and cement fiber siding installations that combine natural beauty with weather resistance. Our cedar siding features natural preservatives for decay resistance, while cement fiber options provide fire-resistant, low-maintenance protection. Both materials are installed with attention to architectural details, offering energy efficiency benefits through improved insulation properties in Portland's climate.
Skylight Installation
Clow installs custom-designed skylights with watertight metal flashing systems that match roofing materials. Our solutions include flat glass, acrylic domes, and operable units that enhance natural lighting while maintaining roof integrity. Each installation includes lifetime leak protection and sun screening options tailored to different ceiling and roof configurations.
Ventilation Systems
Our ventilation solutions address modern energy efficiency challenges by balancing intake and exhaust airflow. We install metal pre-painted flapper vents connected to bathroom/kitchen exhausts, ridge vents, and power fans to control attic moisture. This prevents structural damage from condensation while improving energy efficiency in sealed home environments.
Gutter Installation
We install heavy-gauge aluminum gutters with baked enamel finishes in 4-6 inch sizes, designed to prevent sagging and warping. Our continuous gutter system eliminates seams, while custom-engineered flashing directs water away from vulnerable wood areas. Optional Gutter Shield technology prevents debris buildup, and downspout disconnect services help manage stormwater runoff.
