Delaware Roof Pros provides professional roof ventilation in Delaware, OH for residential and commercial properties across Delaware County and the Olentangy corridor. Ventilation is the line item most often missing from a roofing scope in this county, because it is invisible from the curb and nobody sells it well. It is also the item that quietly decides whether the shingle you paid for reaches the service life printed on its wrapper.
The arithmetic is simple and almost nobody does it. Net free area gets calculated against the attic floor area, divided roughly half to the ridge and half to the eaves, and the intake half is the half that gets skipped. A continuous ridge vent running the full length of a house with no working intake underneath it does not ventilate an attic at all.
What it does instead is pull conditioned air up out of the house through every ceiling light can and top plate it can reach. In July that raises the cooling load. In January it carries household humidity into a cold attic, where it condenses on the underside of the deck and drips back into the insulation, and the homeowner is told there is a roof leak.
The specific local version of this is the perforated vinyl soffit panel. On a great many houses built here since the mid-nineties the vinyl is perforated and looks exactly like intake, and the plywood soffit board behind it was never cut in. Air does not pass through plywood because the panel below it has holes. We check this from inside the attic with a light before quoting anything, and it is among the most common findings we have.
The recommendation that surprises people is the refusal. We do not install powered attic fans. On a house with insufficient intake a fan cannot find air in the soffit, so it takes it from the conditioned space instead, and it becomes a machine that treats a symptom by making the cause considerably worse.
Baffles at the eave are not optional where blown insulation has been topped up, which in this county means most houses that have had an energy audit. Insulation packed hard into the eave closes the intake path just as completely as uncut plywood does. Bath fans get followed to their terminations while we are up there, because a fan discharging into the insulation is a wet deck waiting to happen.
Our licensed and insured team brings the right materials and equipment to every job — ASTM D1970 ice barrier membrane, step flashing woven at sidewalls, counterflashing folded into a ground-in reglet, synthetic underlayment printed with fastener grids, ASTM D3161 Class F seal strips, H-clipped 7/16-inch OSB decking — and backs the work with a written workmanship warranty. We serve Delaware and nearby communities including Powell, Sunbury, Galena, Ashley.

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 ASTM D1970 ice barrier membrane, step flashing woven at sidewalls, counterflashing folded into a ground-in reglet, synthetic underlayment printed with fastener grids, 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 Delaware 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 Delaware County and the Olentangy corridor means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
