Vancouver Roof Pros provides professional roof ventilation in Vancouver, WA for residential and commercial properties across Clark County. Ventilation gets sold as a moss cure and it is not one. Air moving through an attic does nothing to the top surface of a roof, which is where moss lives. We would rather say that plainly than take work under a claim that will not hold.
What ventilation does here is stop the roof rotting from the inside, which in a wet-winter climate is a real and common failure. Warm moist indoor air rises into a cold attic, meets sheathing sitting at outdoor temperature, and condenses on the underside. Do that from November to March every year and you get dark staining across the north-facing rafter bays, then soft plywood, then a roof that has to come off years early.
The ratio gets calculated, not eyeballed. Attic floor area divided by one hundred and fifty gives the net free vent area a roof needs, and that total is split between low intake and high exhaust, with a little extra weight on the intake side. Getting the split wrong is worse than doing nothing at all. A ridge vent above blocked soffits draws its make-up air backwards through can lights and the attic hatch.
The intake side is where nearly every Clark County attic fails, and the cause is the same tree that shades the roof. Fir needles pack into continuous soffit vents until net free area is a fraction of what it was, and blown insulation pushed out to the eave finishes the job. We clear both, fit baffles at every rafter bay, and open the soffit properly rather than adding another vent at the top.
Exhaust bath and kitchen fans through the roof, not into the attic. It sounds obvious. We still find ducts terminating six inches above the insulation in maybe a third of the attics we open, and a single bathroom fan can put several litres of water a week into a space that has no way to lose it again.
Do it while the roof is off if you can. Ridge slot, baffles and soffit work are all cheap during a replacement and awkward afterwards. If the roof is staying, the intake side alone is usually worth doing on its own, and it is reliably the part that gets skipped. Ask whoever quotes your roof what they intend to do about intake.
Our licensed and insured team brings the right materials and equipment to every job — moss rhizoids wedged under the shingle butt edge, the factory sealant strip bond between courses, north-slope drying potential under a conifer canopy, 1x4 skip sheathing left from an original cedar shake roof, hand removal with a plastic-bladed shingle scraper, potassium salts of fatty acids moss treatment — and backs the work with a written workmanship warranty. We serve Vancouver and nearby communities including Camas, Washougal, Battle Ground, Ridgefield.

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 moss rhizoids wedged under the shingle butt edge, the factory sealant strip bond between courses, north-slope drying potential under a conifer canopy, 1x4 skip sheathing left from an original cedar shake roof, 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 Vancouver 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 Clark County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

The standards behind roof ventilation
Quality here is not a matter of opinion — it is written down. The roof ventilation work we do in Vancouver 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.
