Our Pottsville commercial roof repair work centers on wall junctions. Leaks often show where a masonry wall meets a low roof and two older repairs touch.
Pottsville commercial roof repair at a wall starts above the visible gap, because water often enters higher up.
Two repairs done years apart rarely meet cleanly. Different materials, different flashing heights, and a gap of sealant between them make a weak point where the roof turns up the wall.
We inspect the full junction, including the wall covering and counterflashing above it. Water entering through mortar joints or a loose reglet can run behind the roof flashing and show up as a roof leak.
Walls meeting roofs carry most of the leaks on older commercial buildings.
Two patches meeting at a wall corner leave a seam of sealant that cracks as the materials move differently. Both patches are cut back so one detail can span the corner.
Metal tucked into mortar joints pulls out as the mortar ages, opening a path behind the base flashing. Gaps show as dark lines where the metal leaves the mortar joint.
Porous brick and cracked mortar let rain into the wall, where it runs down and exits at the roof line. Wind-driven storms against that wall are the clue to watch for.
Membrane turned up the wall shrinks and tents at the inside corner, leaving a gap water can reach. Corners are reinforced so the new flashing lies flat against the wall.
Wall scuppers rust at the box joints and leak into the wall cavity during heavy runoff. The scupper box and its roof flashing are inspected together.
Stains along an inside wall can be roof, masonry, or humidity. The wet pattern and weather sort them out. Comparing the stain height with the roof line narrows the source fast.
A wet wall line can come from either side of the flashing. The rows show the clues for each.
Junction repairs work from the top of the wall down.
Wall and roof sources are separated first, so roof work goes where the roof leaks and masonry issues are named as such. Findings from both sides go into one written report.
Loose counterflashing comes out, the joint is cleaned, and new metal is set and sealed into sound mortar. Reglets are cut fresh when the old joint has crumbled.
Both old repairs are trimmed back to firm material and replaced by a single continuous base flashing. The base flashing runs up the wall to the right height.
Leaking scupper boxes are replaced or relined, with membrane flashed into the opening. Overflow paths are checked so water has a way off the roof.
Fixing the junction as one detail stops the back-and-forth of patches.
Replacing two mismatched repairs with one detail removes the sealant seam where leaks kept starting. The new detail runs past both old repairs onto firm roof.
Knowing whether water came through the wall or the roof avoids paying for the wrong repair. Masonry findings go to the owner with photos for a mason.
Sealing counterflashing and scuppers stops water from soaking the wall cavity behind finishes. Interior plaster and drywall along the wall stop staining.
Inspecting above the visible gap catches water that would otherwise return after a quick patch. The scope covers the whole junction along with the visible gap.
Call and tell us which wall and whether it leaks in wind-driven rain. That helps separate wall water from roof water.
Four steps take a wall-line leak to a single new detail.
Stain shape, height on the wall, and weather timing hint at whether masonry or the roof is letting water in. Photos from inside help match the stain to the wall.
Base flashing, counterflashing, coping, and the wall above are checked along the full length of the problem area. Coping joints get checked along the way.
Old repairs are cut back until the remaining membrane and metal are firmly attached. Loose material is bagged and removed from the roof.
New base flashing and counterflashing go in as one continuous piece, with photos for your file. The finished junction is photographed end to end.
Pottsville sits within a six-town area where we repair commercial roofs. Pick a town below.
Home base; industrial park and downtown roofs.
Old sign supports and unused roof penetrations.
Plant roofs above stored and packaged goods.
Attached shops with shared walls and transitions.
Roofs carrying layers of older patches.
Their materials or flashing transitions never formed a firm connection. We inspect the full junction, including the wall covering above, since fixing only the visible gap can miss water entering higher and running behind the flashing.
Yes. Rain soaking into porous brick or cracked mortar can run down inside the wall and exit at the roof line. The wet pattern and weather help tell them apart.
Yes. We cover Pottsville from Hazleton and work on older brick and block commercial buildings, starting each visit with the wet pattern inside.
The building address, which wall shows water, how high the stain sits, and whether it follows wind-driven rain or any steady rain.
We repair the roof side of the junction and name masonry problems we find. Tuckpointing and wall repairs go to a masonry contractor.
Smaller junctions often are. Long wall lines or several scuppers can take more than one day, set by weather and access.
Tell us which wall shows water and when. We will inspect the junction from the top down and price one clean repair.
