Strong Contractors serves Washington’s commercial and industrial facilities with self-performed roofing systems built for long-term waterproofing performance. Persistent rainfall, moisture intrusion, and coastal storm exposure demand roofing systems engineered for the Pacific Northwest — not adapted from drier climates. We bring the same self-performed installation standards to every Washington project, regardless of building size or facility type.
Washington's energy code shapes a commercial roof before membrane choice does. It calls for a continuous air barrier and insulation levels that a re-roof can trigger, so we detail roof-to-wall transitions and penetrations for continuity from the start. On rain-heavy sites west of the mountains, getting those transitions right also keeps water out of the wall below.
