Frederick Roof Pros provides professional skylights in Frederick, MD for residential and commercial properties across the Frederick Valley. Nearly every skylight leak we are called to is not actually the skylight. It is the flashing kit, or the total absence of one, and it was decided on the day the unit first went in.
The correct install is unfashionably specific and takes longer than people expect. A unit sitting up on a curb, either factory-made or framed on site to suit the opening. Self-adhered membrane taken up the sides of that curb and lapped out across the surrounding deck. Then a manufacturer step-flashing kit, head apron and sill pan, woven in shingle by shingle. Sealant is a finishing material in that assembly and never a waterproofing one.
Deck-mounted units suit newer roofs with adequate pitch and we fit plenty of them. Three placements we refuse outright: over a valley, beneath a wall that discharges onto the unit, or on a slope shallower than the manufacturer permits. Those three decisions are where most of the chronic leakers in this county came from, and no amount of later flashing work rescues them.
Age is the honest answer more often than repair is. Seal failure showing as permanent haze between the panes, a cracked acrylic dome gone milky and brittle, or a wet drywall shaft with a rotted curb underneath all mean replacement rather than a service call. Twenty-five years is a fair expectation, and a unit that old should come out during a reroof whether or not it has started leaking yet.
Two Frederick-specific notes worth having early. Inside the historic district, visibility from a public way is part of the conversation, so a rear-slope location the Commission will actually consider is worth designing around from the very start, before anyone gets attached to a bright kitchen. And on any slope already feeding a single gutter outlet, a new curb changes how water moves across the field above it and around both sides of it.
Where a room simply needs daylight and not a view of the sky, we will steer you toward a tubular device instead. Far less deck cut, far less flashing to go wrong, a fraction of the cost, and no shaft to frame and finish. It is a much smaller job with a much smaller invoice and we recommend it often, including to people who called us asking for a skylight.
Our licensed and insured team brings the right materials and equipment to every job — six-inch K-style trough hung on hidden hangers at sixteen inches, three-by-four leaders set by roof-plane area rather than corner count, level spreaders that break a leader back into sheet flow, vegetated filter strips receiving discharge out to the lot line, self-adhered high-temperature membrane wrapped at every eave and valley, half-inch CDX sheathing replacement over sounded rafters — and backs the work with a written workmanship warranty. We serve Frederick and nearby communities including Ballenger Creek, Urbana, Green Valley, Linganore.

Materials, equipment and how we do skylights
The difference between skylights that lasts and skylights that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with six-inch K-style trough hung on hidden hangers at sixteen inches, three-by-four leaders set by roof-plane area rather than corner count, level spreaders that break a leader back into sheet flow, vegetated filter strips receiving discharge out to the lot line, 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 Frederick 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 the Frederick Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Frederick Chooses Frederick Roof Pros
- ✓We set the number of downspouts from roof-plane area, because the county holds each rooftop leader to five hundred square feet of drainage area. A long slope gets a second outlet rather than a fatter one.
- ✓Every proposal includes a sketch marking where each leader lands and what receives the water, since the rule is that discharge leaves through vegetation, without scouring, out to the property line.
- ✓We will not build a dry well, a stone pit or a buried infiltration box on this valley floor. That is the practice the state manual restricts in karst and the geological survey ties to soil piping.
- ✓Inspections start in the yard. Slumped soil, fenceposts out of plumb, sticking doors and hairline mortar cracks are read from the ground, and they sit on the survey's own watch list for carbonate terrain.
The standards behind skylights
Quality here is not a matter of opinion — it is written down. The skylights work we do in Frederick follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
Every skylights project in Frederick gets the same attention, whether it is a single room or a full commercial job. We show up on schedule, keep the site clean, and stand behind the work — the estimate is free and there is no pressure.
