Exposed Fastener Metal Roof

What This Service Involves

An exposed-fastener metal roof is the practical, budget-friendly metal option for Puget Sound outbuildings, agricultural structures, and simple-slope homes. Panels are screwed directly through the metal into the deck or purlins using gasketed fasteners engineered to seal against our persistent rain. While the fasteners are visible, proper screw placement and periodic gasket maintenance keep these roofs watertight for decades in the Northwest. We use quality washered screws and correct torque so the seals hold up against constant moisture and seasonal expansion.

Benefits

Lower up-front cost than concealed-fastener metal systems; fast installation on straightforward roof shapes; excellent for pole barns, shops, and rural Washington structures; easy to repair panel-by-panel if needed; durable painted finishes that resist Northwest algae staining

Our Process

1) Confirm purlin or deck layout and fastener spacing plan; 2) Install underlayment appropriate to the structure; 3) Screw panels with gasketed fasteners at engineered spacing; 4) Add ridge, eave, and closure trim then verify seal integrity

What Affects the Cost

Panel gauge and finish quality; roof size and framing type; fastener grade and gasket specification; trim, closures, and flashing needs; site access for rural or acreage properties

Best Time of Year

Dry summer conditions give the best gasket seating and sealant performance for exposed-fastener roofs in Western Washington, though many outbuilding projects proceed in shoulder seasons.
