Olympia Roof Pros provides professional roof ventilation in Olympia, WA for residential and commercial properties across Thurston County and the south Sound. The buildings that dominate this city's roof area are mechanically ventilated and houses are not. That is why attic moisture is a serious defect on an agency building and an afterthought on a residence, and it is the commonest fault we find here.
The physics is simple and the execution is usually wrong. An attic needs balanced intake and exhaust, close to half at the eaves and half at the ridge, and a system that has ridge vent cut across the whole house with painted-shut or insulation-blocked soffit vents underneath will pull its makeup air out of your living space instead. Warm indoor air then condenses on cold sheathing all winter.
We will argue against powered attic fans nearly every time. They move air, and in a house with restricted intake most of what they move is conditioned air drawn up through ceiling penetrations, which raises your heating cost and can backdraft a combustion appliance. Fixing the intake costs less than the fan and solves the problem the fan was hired to hide. Fix the eaves first, then talk about the fan.
Vaulted ceilings are the other recurring problem in this housing stock, and there are a lot of them in the seventies and eighties inventory around Olympia. A cathedral rafter bay needs a continuous vent channel from the eave to the ridge with a real baffle holding the insulation off the sheathing, and stuffing the bay full of batt is how a deck rots quietly for fifteen years without ever leaking.
Diagnosis happens in the attic, not on the roof. We look for rusted nail points, dark staining on the sheathing between the rafters, compressed insulation over the top plates, and bath fans that terminate into the attic rather than through the roof or the wall. Those four observations tell us more than any amount of counting vents from the driveway, and the readings take about ten minutes.
Then we count net free area properly, in square inches, against the floor area you have, and write the number in the scope. Anybody can add a ridge vent during a re-roof. The point is whether the intake underneath it exists, and that is a soffit and blocking conversation before it is a roofing one. Without it, the ridge vent is decoration.
Our licensed and insured team brings the right materials and equipment to every job — quarter-inch-per-foot tapered polyisocyanurate cut to a drain-point layout, edge metal carrying an ANSI/SPRI ES-1 test rating with fastening to match, hot-air-welded thermoplastic seams probed by hand with a dull hook, two-inch core cuts patched and logged against a numbered roof plan, 24-gauge Kynar 500 standing seam on floating expansion clips, six-nail fastening set inside the manufacturer's published nail zone — and backs the work with a written workmanship warranty. We serve Olympia and nearby communities including Lacey, Tumwater, Yelm, Tenino.

Materials, equipment and how we do roof ventilation
The difference between roof ventilation that lasts and roof ventilation that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with quarter-inch-per-foot tapered polyisocyanurate cut to a drain-point layout, edge metal carrying an ANSI/SPRI ES-1 test rating with fastening to match, hot-air-welded thermoplastic seams probed by hand with a dull hook, two-inch core cuts patched and logged against a numbered roof plan, 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 Olympia 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 Thurston County and the south Sound means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Olympia Chooses Olympia Roof Pros
- ✓We quote your summer date and your November date side by side, because in a capital city the dry weeks are sold against a public bid calendar and the gap between those two prices is real money you should get to decide about.
- ✓Every scope carries unit prices for sheathing, blocking, fascia and flashing before the tear-off starts, the way a public change order has to be written, so nothing on your job gets renegotiated from the top of a ladder.
- ✓We will tell you that nobody owes you prevailing wage on a private house. If a bid quotes the published Thurston County rate at you as a justification, that is a public works number being used as a sales line.
- ✓We do not install new concrete or clay tile in this market. The bench that can flash and maintain it properly is thin here, and we would sooner turn the work down than leave you with a roof nobody local will service.
