Johnson City Roof Pros provides professional chimney flashing in Johnson City, TN for residential and commercial properties across Washington County and the Tri-Cities. A chimney is a masonry wall standing in the weather with a roof wrapped around its base, and in this valley masonry takes a beating. Getting the order of operations right is most of the job.
Freeze and thaw destroy mortar joints from the outside in. Water soaks into the joint, freezes, pushes the sand and lime apart, and the next rain gets in a little deeper. Crowns crack across their width. Brick faces spall off in sheets on the exposure that stays wet longest. Not one of those is a roofing defect, and every one of them arrives as water on a ceiling.
Which is why we look at the masonry before we quote flashing. Cutting a counterflashing reglet into a joint that is already soft gives you a groove that will not hold the metal or the sealant for more than a couple of winters. Repoint first, rebuild or recast the crown if it is cracked, and then flash into sound mortar. Reversing that order is the most common way this repair gets sold twice.
The flashing itself is two separate pieces of metal and it always should be. Step flashing woven into the shingle courses handles the water on the roof. Counterflashing set into the masonry and bent down over the steps handles the water on the wall. A single piece of aluminum caulked to the brick, which is what we find on maybe half the chimneys we open, is not flashing. It is sealant with a job it cannot keep.
Anything wider than roughly thirty inches across the up-slope face needs a cricket behind it. Skip that and the stack works as a dam, holding leaves, snow and ice against its back wall for weeks at a stretch, and no flashing detail survives the treatment. Framed and metal-clad, tied into the step flashing, it is not an expensive addition on a roof that is already open.
On prefabricated chases, the chase cover is usually the culprit rather than any flashing. Flat galvanized pans hold water, rust through from the inside, and drip down the flue chase. We replace them with a sloped stainless or copper pan with a cross break and a proper drip edge. We look at the flue liner and the cap while we are up there, and refer that work out to a sweep where it belongs.
Our licensed and 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 chimney flashing
The difference between chimney flashing that lasts and chimney flashing 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 state credential at all.

If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
