Alpharetta Premium Roofing provides professional roof ventilation in Alpharetta, GA for residential and commercial properties across north Fulton County. Steep roofs in this city usually have generous attic volume and nothing like enough continuous ridge. A plan with four gables, two dormers and a hip over the garage has short ridge runs, and short ridge runs cannot exhaust the attic sitting underneath them.
The code wants net free ventilating area equal to one three-hundredth of the attic floor beneath it, divided roughly half to intake and half to exhaust. On a long simple gable that is easy. On an Alpharetta roof it usually is not, and the shortfall almost always sits at the exhaust end. Intake is usually the half people blame and exhaust is usually the half at fault.
So we measure the attic footprint, add up the ridge that is actually available, subtract what the hips take out of it, and count the real net free area of the soffit rather than assuming perforated vinyl is open. Very often the soffit is packed solid with blown insulation and the usable ridge is half what the plan suggested. Both of those findings change the recommendation completely, which is why we go and count.
Fixing the exhaust means cutting the deck along the ridge and working from both sides of a peak. On a five in twelve that is a morning. On a twelve in twelve it is anchors, a two-person setup and a full day, and the vent hardware itself is a small fraction of what the day costs. Nobody sells a ridge vent for what the day it takes actually costs.
So do not buy ventilation as a standalone job on a steep roof. Buy it as a line item on the replacement, when the staging is already standing and the ridge is already open. Anyone who rings us for ridge vent alone on a ten in twelve will hear this, and will then hear a price that makes the same point rather more sharply.
The exceptions are honest, cheap and worth knowing. Soffit intake can be opened from a ladder. Baffles go in from inside the attic. Gable-end vents and fans are worked from outside the wall. Where the shortfall is at the intake, and in this city it frequently is, none of the fix involves setting foot on the steep part at all. We will tell you which half of the balance is short before quoting either side of it.
Our licensed and insured team brings the right materials and equipment to every job — roof bracket scaffolds built to the plane, ridge-hooked crawling boards, rafter-anchored personal fall arrest points, hand-sealed courses above twenty-one in twelve, six-nail fastening with ASTM D4586 cement spots, double underlayment below four in twelve — and backs the work with a written workmanship warranty. We serve Alpharetta and nearby communities including Roswell, Johns Creek, Milton, Sandy Springs.

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 roof bracket scaffolds built to the plane, ridge-hooked crawling boards, rafter-anchored personal fall arrest points, hand-sealed courses above twenty-one in twelve, 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 Alpharetta 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 north Fulton County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
