Reston Premium Roofing provides professional flat & low-slope roofing in Reston, VA for residential and commercial properties across western Fairfax County. This is the page where the code changes the answer outright. R905.2.2 permits asphalt shingles only on slopes of two units in twelve or greater, and from two up to four in twelve it requires doubled underlayment. Many Reston connector roofs are shingled below that line right now.
Carport links, entry canopies, garage connectors, dormer decks and the shallow sections tucked in between the pitched planes of the contemporary designs. They were built in an era with different paperwork and looser habits, they are small, they are invisible from the ground, and they cause a wildly disproportionate share of the interior damage we get called out to look at.
So we bring a pitch gauge and use it before writing a number. If the connector reads one and a half in twelve, replacing what is up there in kind is not lawful work and we will not do it, whatever the last contractor did. That single measurement changes the material, the price and occasionally the whole conversation about the job you thought you were buying.
Below two in twelve the right answer is membrane. For most residential connectors that means a sixty-mil thermoplastic sheet, mechanically attached or fully adhered, heat welded at the seams, turned up any abutting wall as real flashing and closed off in a termination bar instead of a bead of sealant. On very small or heavily penetrated sections, self-adhered modified bitumen is the more practical choice and we will recommend it.
Between two and four in twelve, shingles are legal and we double the underlayment because the code says to: a nineteen-inch starter strip at the eave, then thirty-six-inch sheets lapped nineteen inches up the slope. That step gets left out constantly. It adds almost nothing to the price, and it separates a shallow roof that performs from one that draws water back under its own courses.
Drainage decides more of this than the membrane does. Sections settled into a low spot, connectors pitched toward the house, outlets blocked since the Carter administration. Tapered insulation fixes that properly and another coat of anything does not. Where a flat section sits over finished living space we open it and look first, because wet board does not dry and we would rather lose the job.
Our licensed and insured team brings the right materials and equipment to every job — a self-adhering ice barrier carried inside the exterior wall line, double underlayment on connector slopes under four in twelve, six fasteners per shingle against a code floor of four, twenty-four-inch open valley metal in twenty-six gauge, a cricket framed on the ridge side of a wide stack, kick-out flashing where an eave runs into a vertical sidewall — and backs the work with a written workmanship warranty. We serve Reston and nearby communities including Herndon, Vienna, Oakton, McLean.

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 a self-adhering ice barrier carried inside the exterior wall line, double underlayment on connector slopes under four in twelve, six fasteners per shingle against a code floor of four, twenty-four-inch open valley metal in twenty-six gauge, 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 Reston 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 western Fairfax County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Reston Chooses Reston Premium Roofing
- ✓Every quote runs in two columns. The left is what the 2021 Virginia Residential Code obliges anyone to do on your roof. The right is what we install instead, priced separately, so you can strike a line and pay less.
- ✓Fairfax County is not allowed to ask for more. Section 36-98 of the Code of Virginia makes the statewide code supersede county building regulations and expressly overrides local ordinances requiring particular materials or finishes on a single-family house.
- ✓The one exception is Table R301.2, which the code hands to the locality to fill in. Fairfax designated an ice barrier as required and the City of Alexandria did not, so we install to the county your house is actually in.
- ✓Four fasteners per strip shingle is the floor under R905.2.6. We set six, in the manufacturer's nail zone, and photograph the pattern on each slope before the next course hides it.
