Kent Roof Pros provides professional commercial roofing in Kent, WA for residential and commercial properties across the Green River valley and south King County. The flat ground between the hills is warehouse, distribution and light industrial floor area, and the roofs over it are large, low slope and sitting on the same filled valley bottom as the houses. That last part changes how a competent survey is done. The ground is the variable.
Buildings on consolidating alluvium and fill do not settle uniformly. A structure loaded heavily at one end settles more there, and over years the drains, scuppers and crickets that were correct on the original roof plan end up at elevations the deck no longer matches. The roof plan is a historical document at that point, not a description of the building. Drawings age and decks move, which is a poor combination for a drainage design.
So we do not price off a drawing. We walk the roof on a numbered grid after rainfall, record ponding depth and extent, shoot relative elevations at drains and high points, and take core cuts to log the existing assembly and check whether the insulation is wet. What comes back is an as-is survey, and the tapered layout is designed from that. The survey is the deliverable, and you keep it.
It is worth being clear about a Washington detail, since contractors from other states market around it. This state registers contractors as general or specialty, distinguished by trade scope and bond amount rather than by any ladder of project classes, and there is no roofing examination behind either. Nobody's registration category tells you whether they can survey your roof, so ask about method instead. That question separates bidders quickly.
Occupied buildings set the rest of the terms. Tear-off and dry-in have to close the same day over live racking, so the day's work is sized to the forecast and the crew, mechanical curbs and gas lines are raised or reset rather than roofed around, and interior protection under the work area is agreed in writing before anything is opened up. Forecast, not optimism, sets the daily footprint.
We work in mechanically attached and fully adhered single ply, two-ply modified bitumen and coating restorations where the substrate justifies one, with a tightened fastening pattern in perimeter and corner zones because that is where uplift starts and where the cheap bids save their money. Coating restorations get proposed only where the cores come back dry and drainage is positive, which on this valley floor is a smaller share of buildings than the coating industry suggests.
Our licensed and insured team brings the right materials and equipment to every job — Class A laminated asphalt shingles set on a six-nail pattern, self-adhered ice and water membrane at eaves, valleys and penetrations, tapered polyisocyanurate laid to a re-surveyed drainage plane, two-ply SBS modified bitumen at porch and addition tie-ins, concealed-clip standing seam panels over high-temperature underlayment, sheathing re-planed with ripped cedar shims before underlayment goes down — and backs the work with a written workmanship warranty. We serve Kent and nearby communities including Auburn, Federal Way, Renton, Tukwila.

Materials, equipment and how we do commercial roofing
The difference between commercial roofing that lasts and commercial roofing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with Class A laminated asphalt shingles set on a six-nail pattern, self-adhered ice and water membrane at eaves, valleys and penetrations, tapered polyisocyanurate laid to a re-surveyed drainage plane, two-ply SBS modified bitumen at porch and addition tie-ins, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Kent job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in the Green River valley and south King County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Kent Chooses Kent Roof Pros
- ✓We establish which ground your address sits on, valley fill or glacial hillside, before a specification is written, because the two need different roofs
- ✓Ridge and eave offsets are measured and recorded on the first visit and again at completion, so the file shows whether anything is still moving
- ✓We decline coating work where the ponding traces back to building settlement, and we put the reason in writing rather than taking the job quietly
- ✓Nobody here will write a hail claim on a Puget lowland roof. We chalk a test square, count the hits and give you the number even when it kills the job
The standards behind commercial roofing
Quality here is not a matter of opinion — it is written down. The commercial roofing work we do in Kent follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
Every commercial roofing project in Kent gets the same attention, whether it is a single room or a full commercial job. We show up on schedule, keep the site clean, and stand behind the work — the estimate is free and there is no pressure.
