Galvalume Roofing

What This Service Involves

Galvalume roofing uses a steel panel coated in an aluminum-zinc alloy that dramatically outlasts traditional galvanized steel in the wet Puget Sound climate. The aluminum in the coating provides barrier protection while the zinc offers sacrificial corrosion resistance at cut edges, a combination well suited to our constant moisture. It is a cost-effective, long-lasting substrate available bare for a bright industrial look or painted in a wide range of colors. For Western Washington homeowners and property owners wanting durable metal at a sensible price, Galvalume delivers dependable, corrosion-resistant performance.

Benefits

Aluminum-zinc coating far outlasts standard galvanized steel in wet climates; excellent value for the corrosion protection provided; available bare or in many painted finishes; suitable for homes, shops, and agricultural buildings; strong runoff performance in heavy Northwest rain

Our Process

1) Confirm profile, gauge, and finish for the application; 2) Install underlayment and eave protection for wet-climate runoff; 3) Install Galvalume panels with compatible gasketed or concealed fasteners; 4) Detail ridge, valley, and penetration flashings then inspect seams

What Affects the Cost
