Johnson City Roof Pros provides professional skylights in Johnson City, TN for residential and commercial properties across Washington County and the Tri-Cities. In winter most of what gets reported to us as a leaking skylight is nothing of the kind. It is condensation shedding off the coldest piece of glass in the building, on a morning after the temperature dropped hard under a clear sky.
That is worth knowing before you spend money. Water that appears at the bottom corners of the glass on frosty mornings and never appears during rain is coming out of the room, not off the roof. The cure is a warmer detail: an insulated and air-sealed shaft, a unit with a thermally broken frame and warm-edge spacers, and a bathroom fan that actually vents outside rather than into the attic.
When it is genuinely a leak, the flashing is almost always the story. We replace units rather than reflash old ones wherever the frame is beyond about twenty years, because the gaskets and the seal on the glazing unit have a life of their own and there is little sense putting new metal around a frame that is next in line. Reflashing an old unit costs two thirds of a replacement and buys a third the life.
Curb-mounted units get our vote on this ground. The curb lifts the whole assembly above the plane of the roof, which keeps the glass clear of the wet leaf mat and snow that sits on a shaded slope well after the sunny side has cleared. We build the curb tall, wrap it in self-adhered membrane, and step-flash it into the courses rather than relying on a one-piece pan.
We are cautious about adding new skylights to a shaded plane, and we say so before taking the order. That slope is where the snow lingers, where the algae grows and where the roof stays wet the longest, and it is also the one that delivers the least daylight for the risk. If the room can be lit from the other side of the ridge, light it from there.
Tubular units are underrated and we fit a lot of them in hallways, closets and stair landings. One small curb, a reflective tube, no shaft to frame and no meaningful condensation surface. They give up the view and they keep almost everything else. They also add very little to the leak risk, since one small curb is a far simpler thing to flash than a four-foot opening.
Our insured team brings the right materials and equipment to every job — hand-sealed shingle tabs, eave and valley self-adhered membrane, floating clip standing seam panel, slotted fastener hole elongation, ASTM C1167 Grade 1 freeze rating, heat-welded thermoplastic membrane seam — and backs the work with a written workmanship warranty. We serve Johnson City and nearby communities including Jonesborough, Elizabethton, Erwin, Kingsport.

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 hand-sealed shingle tabs, eave and valley self-adhered membrane, floating clip standing seam panel, slotted fastener hole elongation, 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 Johnson City 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 Washington County and the Tri-Cities means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Johnson City Chooses Johnson City Roof Pros
- ✓We write up each roof plane on its own line, because on a hillside lot in the ridge and valley the shaded slope and the sunny slope are effectively two different roofs of two different ages.
- ✓We test for deck condensation before we sell a leak repair, since a stain that appears on a clear frosty morning is coming from inside the attic and new shingles will not touch it.
- ✓We schedule tear-offs into a window where the sealant strips can actually bond, and when the calendar forces a cold install we hand-seal the tabs and say so on the invoice.
- ✓We will tell you where your contract sits against the $25,000 licensing threshold, and we will tell you when a competitor is legally allowed to have no TENNESSEE credential at all. That stops at State Street in Bristol, because Virginia licenses contractors from a thousand dollars up and its building officials cannot issue a permit without the number.
The standards behind skylights
Quality here is not a matter of opinion — it is written down. The skylights work we do in Johnson City 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 Johnson City 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.
