Gaithersburg Premium Roofing provides professional flat & low-slope roofing in Gaithersburg, MD for residential and commercial properties across upper Montgomery County. Low-slope work in Gaithersburg is rarely a whole roof. It is a rear addition, a porch, a garage link, a dormer cheek or a third-floor terrace, and it is usually a couple of hundred square feet wedged between two pitched planes. Between two and four in twelve the underlayment doubles.
On something that small, membrane is almost free and the price is entirely in the edges. The base flashing height up the adjoining wall, the counterflashing into the siding or the brick, the transition where the pitched field discharges onto it, the scupper or the outlet, and the termination bar. That is where the money and the failures both live.
We specify by what the deck can actually do. Below two in twelve, asphalt shingles are not permitted and no amount of extra underlayment makes them acceptable. Self-adhered modified bitumen suits small enclosed decks with awkward corners. Sixty-mil membrane suits larger open ones. Neither goes down over a deck that holds water. It is the smallest area on the house and the likeliest to leak. Bundling small work into a larger job is the cheapest advice we give.
Ponding is the first thing we check and often the whole diagnosis. If water stands more than two days after rain, the fix is framing, tapered insulation or a relocated outlet, not a thicker covering. Selling a membrane over standing water is selling a warranty claim that will be denied on inspection. Water under a terrace surface shows itself only in the ceiling below. Every membrane manufacturer excludes ponding and every one enforces it.
Terraces and walkable decks over living space need saying separately. Anything people stand on wants a protection layer and a proper drainage path under the surface, and the tie-in to the door threshold is the detail we see failed most often. We photograph that assembly before it is covered because nobody can inspect it afterwards. None of this is expensive while the crew is already here.
Because these areas are small, doing them alongside the pitched roof costs a fraction of doing them as their own job. If you have a rear addition with a tired deck and a shingle field with five years left, we will usually tell you to wait and bundle them, and we will patch the deck properly in the meantime. Get the terminations right and the field outlasts everything around it.
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 flat & low-slope roofing
The difference between flat & low-slope roofing that lasts and flat & low-slope roofing 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.
