Offices, shops, warehouses and apartment buildings across Bellevue have flat roofs that sit under rain for months. We repair, replace and maintain TPO, PVC, EPDM, modified bitumen and built-up systems, and we plan the work so the building stays open.
Bellevue has a wide mix of commercial roofs: office buildings and retail downtown, older warehouses and shops along the Bel-Red corridor, strip centers in Crossroads and Factoria, and apartment and condo buildings across the city. Nearly all are flat or low-slope. Before we recommend anything we look at the deck, the insulation, how many roof systems are already in place, where water stands after rain and how the drains and scuppers are working.
The wet season is what tests a flat roof here. Rain falls for days at a stretch, and fir needles and leaves block drains quickly. We work with TPO and PVC single-ply, EPDM rubber, modified bitumen, built-up roofing, coatings and sheet metal. Seams, parapet flashings and the curbs around rooftop units are where leaks start most often, so those details get the most attention. Tapered insulation can move water to the drains on a dead-flat deck.
Rules for commercial roofs are tighter than for houses. The City of Bellevue allows a commercial roof replacement without a permit only when no more than two sheets of sheathing are replaced, and the state energy code can require added insulation when a roof is replaced. Condo and apartment buildings can fall under the state's building enclosure law. We check what applies to your building, and we plan the work so tenants can stay open.
Commercial roofing in Bellevue: common questions
Can you work while the business stays open?
Usually, yes. Work is done in sections so the building stays dry and entrances stay clear. Tell us your hours and delivery times at the site visit.
Does a commercial re-roof in Bellevue need a permit?
Often it does. The City exempts a commercial replacement only when sheathing repair is limited to two 4x8 sheets. We check the rule for your building.
How often should a flat commercial roof be checked?
Twice a year is a sound habit here: once in fall before the rains and once in spring. Drains should also be cleared after big wind storms.
