Water Down The Inside Of A Wall
Plaster bubbles or paint peels high on an exterior wall, worst after a rain with wind behind it.
Open joints in the coping let water into the parapet, and it runs down behind the wall flashing.

As a Thompsonville commercial roofing contractor, we replace and repair flat roofs on brick storefronts, mixed-use blocks, and older commercial buildings in this Enfield village.
Thompsonville commercial roofing work usually happens behind a parapet wall, on a flat roof over shops with apartments or offices above. Many of these roofs have been covered more than once, and the brick coping has shifted with decades of freeze and thaw.
Access sets the plan. Narrow streets and shared walls leave little room for a dumpster or lift, so we map where materials go up, where debris comes down, and how tenants keep using their entrances.

Older brick buildings show roof trouble in a few familiar places. Here is what tenants notice and what we find above.

A brown ring spreads on the ceiling around a fixture near the middle of the room.
An interior drain with a cracked bowl or a loose clamping ring is letting water past the membrane.
Upstairs tenants hear water dripping inside the ceiling after storms, with no stain yet.
Two or three roofs are stacked on the deck and the bottom layer holds water from an old leak.
Gutters and downspouts on the street side stay dry during storms, yet stains spread inside.
The roof drains to a single interior drain, and a sag in the deck holds water away from it.
A full replacement on an older downtown building fixes the details that patches keep missing.
Stacked roofs come off to the deck, wet boards go out, and new insulation and membrane go on, so the roof sheds water from one known layer.
New coping caps or metal covers over the parapet stop water from entering the wall from above, which ends the plaster damage on upper floors.
Cracked drain bowls and missing strainers get replaced and clamped to the new membrane, so the low point of the roof carries water away again.
Work hours, entrances, and noisy days are set before the crew starts, and each tenant hears what is happening on the roof above them.
These are the systems that fit downtown flat roofs and the shops behind them.

A white welded membrane suits flat roofs over shops, and its seams hold well around the small units on mixed-use blocks.
TPO Roofing details
Rubber membrane works well on long, narrow roofs between shared walls, where flexible flashing has to turn up brick parapets.
EPDM Roofing details
Larger plant roofs near the village center get membrane systems laid out around exhaust fans and ductwork.
Industrial Roofing details
Sloped rear additions and garages behind downtown buildings take standing seam or exposed fastener panels.

Send the address and the number of tenants. We plan access with you before pricing the roof.
Get A Free EstimateDowntown jobs follow this order so tenants keep working and the street stays clear.
We walk the roof, check the coping and wall flashing, and take core cuts to count the old layers. Inside, we look at the stains tenants have reported.
A hoist spot for roofing materials, a debris chute, and a dumpster location are chosen with you, and any street or sidewalk use is cleared with the town first.
Old layers come off in sections, deck damage is fixed, and new insulation, membrane, and parapet flashing go on before each section is closed.
New coping or metal caps go on once the wall flashing is done, then we walk the roof with you and record what was installed.
Photos of the coping, flashing, and drains go into a closeout record, so the next owner or tenant knows what is on the roof.

Answers to what downtown owners ask before a roof replacement.
Yes, in most cases. We stage materials off the sidewalk, work one section at a time, and close each one watertight before the crew leaves. Noisy tear-off is scheduled with tenants, and entrances stay usable during the job.
More roofing questionsIt depends on what the core cuts show. When there are already two roofs on the deck, or the bottom layer is wet, everything comes off. One dry, attached roof can sometimes take a recover where code allows.
Thompsonville is a village within the Town of Enfield, so permits go through Enfield's Building Inspection department, which takes applications online. We pull the permit as part of the job.
The wall flashing is stripped and replaced up the inside face of the parapet, and the coping on top is reset or covered with new metal caps. That keeps water out of the wall from both directions.
Sometimes, when the core cuts show one dry roof and the parapet flashing can still be carried high enough above the new surface. Two existing layers or wet insulation mean the old roof comes off.
