Gaithersburg Premium Roofing provides professional roof ventilation in Gaithersburg, MD for residential and commercial properties across upper Montgomery County. Almost every ventilation fault we find here is a starved intake being treated as though it were weak exhaust. Somebody added a ridge vent, the attic did not improve, and the next contractor suggested adding a powered fan on top of that. Adding exhaust without intake makes the problem worse.
The physics is unforgiving about it. Exhaust without matching intake does not move outside air through the attic. It pulls conditioned air up through every gap in the ceiling plane instead, which raises your heating bill in January and puts household moisture on the underside of the sheathing where it condenses. In July the same imbalance pulls humid outside air in instead.
On the production housing that dominates Gaithersburg the intake is usually the culprit. Boxed cornices were framed without a slot cut behind the soffit panel. Perforated aluminum got painted until the perforations closed. Blown insulation slid down the rafter bay and buried the vent. All three read as a ventilated attic from the ground and none of them is one. None of those repairs is roofing and all are cheaper.
So we count. Intake and exhaust are calculated in square inches of net free area, the intake is opened at the cornice with the slot cut and screened, baffles hold a clear airway above the insulation at the eave, and the numbers go on the estimate. The work is cheap while the crew is already there and expensive as its own visit. Doing it during a tear-off costs a fraction of a separate visit.
Some attics should not be vented at all, and this is where we will talk you out of the sale. If your top floor is a cathedral ceiling with foam against the deck, or a sealed and semi-conditioned attic in newer construction, cutting a ridge vent into it does active harm. We check which assembly you have before we quote anything. A powered fan simply draws its air back down the ridge.
We are also happy to tell you the fix is not ours. Bath fans terminating into the attic, a missing air barrier at the top plates, or recessed cans leaking into the space are all common here, and all of them cause stains people call roof leaks. Fixing them is worth more than any vent we could sell you. A ridge vent above any of those is decoration.
Our licensed and insured team brings the right materials and equipment to every job — debris chuted straight into a trailer set on a shared apron, lead pipe boots in place of the builder's molded rubber collars, step flashing replaced piece by piece and never reused, a cemented starter strip turned up both rakes, kick-out diverters where an eave dies into siding, sub-fascia sounded and made good before any trough is rehung — and backs the work with a written workmanship warranty. We serve Gaithersburg and nearby communities including Rockville, Montgomery Village, Germantown, North Potomac.

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 debris chuted straight into a trailer set on a shared apron, lead pipe boots in place of the builder's molded rubber collars, step flashing replaced piece by piece and never reused, a cemented starter strip turned up both rakes, 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 Gaithersburg 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 upper Montgomery County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Gaithersburg Chooses Gaithersburg Premium Roofing
- ✓We quote the fixed work first and the covering second, because on the short roofs that dominate this city the tear-off, the metal, the flashings and the crew day set the price and the shingle barely moves it.
- ✓We will argue you out of the premium shingle tier and the extended system warranty, and put the same money into 26-gauge valley metal, lead boots and step flashing that is replaced rather than reused.
- ✓Skylights, troughs, fascia and intake work get bundled into the roof's own mobilization, because paying twice for the same ladders is the most common avoidable cost on a job this size.
- ✓Inspections are paid and the fee never comes off later work, which is what makes it possible for us to tell you that your roof is fine and go home.
