West Jordan Roof Pros provides professional roof ventilation in West Jordan, UT for residential and commercial properties across the Salt Lake Valley. Ventilation on the valley floor is a drying system, not a cooling one. For weeks each winter the sheathing sits colder than the dew point of the air inside your house, and whatever moisture reaches it condenses there and stays put until something moves it along.
Which is why we start below the insulation rather than at the ridge. A bath fan or dryer duct terminating in the attic, an uninsulated hatch, a leaky can light, a plumbing chase left open at the top plate: those put more water into a valley attic in a week than a roof leak does in a month, and sealing them is cheap. We inspect for those on every ventilation quote and list them first.
Only then does airflow help. The code ratio for a vented attic is one part net free area to three hundred parts of attic floor, split roughly half at the ridge and half at the eaves. On a fifteen-hundred-square-foot attic that works out to five square feet total, so two and a half at the ridge and two and a half at the soffits. Where the ceiling is well sealed, one part to six hundred is permitted.
Net free area is not the same as hole area. A vent's rating counts only the openings through its screen and baffle, so a soffit panel that looks perforated across its whole face may deliver a small fraction of what its size suggests. We read the manufacturer's figure off each product and add them up instead of counting vents. Two ridge vents of identical length can differ twofold in what they pass.
Intake is the half that is always short. Soffit vents get painted over, packed with blown insulation, or blocked because somebody added depth to the attic without installing baffles first. With intake short, exhaust moves almost nothing through the attic. What it does instead is draw conditioned air up out of the rooms below and deliver that moisture to the cold deck. That is the mechanism behind most mystery stains we see between December and February.
Powered fans we argue against for the same reason. They depressurize an attic with no intake and draw humid house air through every gap in the ceiling below. For most houses here the right answer costs a few hundred dollars: seal the ceiling plane, clear the soffits, baffle every rafter bay, run a continuous ridge vent.
Our licensed and insured team brings the right materials and equipment to every job — vapor-permeable synthetic underlayment, self-adhered eave and valley membrane, ring-shank sheathing nails at six inches on center, copper-bearing algae-resistant granules, polymer-modified asphalt shingle mat, 24-gauge standing-seam steel over a drainage mat — and backs the work with a written workmanship warranty. We serve West Jordan and nearby communities including Taylorsville, Murray, Midvale, South Salt Lake.

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 vapor-permeable synthetic underlayment, self-adhered eave and valley membrane, ring-shank sheathing nails at six inches on center, copper-bearing algae-resistant granules, 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 West Jordan 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 Salt Lake Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why West Jordan Chooses West Jordan Roof Pros
- ✓We meter the roof sheathing from the attic before quoting, and those readings go into the estimate
- ✓Eave courses are probed by hand, because the bottom four feet is where valley roofs fail first
- ✓Vapor-permeable underlayment across the field, so a damp deck can still dry upward through the assembly
- ✓Ceiling-plane air sealing is quoted before extra roof vents, because it fixes more attics for less money
