Shared Walls
Leaks at Party Walls
Flashing on a shared wall belongs to two roofs at once, and when one side fails, water reaches both buildings.

Pottsville Commercial Roofing Contractor
Outlets, Height Changes, and Shared Walls Planned as One Drainage Path
As a Pottsville commercial roofing contractor, we replace roofs on connected commercial blocks with drainage planned across every section that sheds water to the next.
Pottsville Commercial Roofing on Connected Blocks
Pottsville commercial roofing on a row of joined buildings has to follow the water across property lines. One roof often drains across or into its neighbor.
Before recommending work, we find every outlet, scupper, and height change along the block. Ownership lines go on the same drawing so everyone sees where water crosses.
Replacing one section can raise its height or move its outlet, which changes how the adjoining roof drains. We design for those connections even when contracts and upkeep stay separate.
- Every outlet and scupper on the block located
- Height changes between buildings measured
- Shared walls and parapets inspected from both sides
- Ownership lines marked on the drainage plan
Commercial Roofing Problems on Pottsville Blocks
Joined roofs share their troubles. These four conditions come up along most commercial rows.
Drainage
Outlets Blocked by a Neighbor
A raised roof next door can trap water against the wall, and the lower roof floods at its edge.
Masonry
Damp Brick Below the Coping
Open joints in old coping let water into masonry that then shows up as stains on upper-floor walls.
Ponding
Water Held Near the Rear Wall
Settled roofs along the back of a block often hold water where the gutter or scupper sits too high.
Openings
Chimneys and Old Flues
Old masonry flues on commercial blocks carry cracked crowns and loose flashing that leak into upper floors.
Winter
Snow Trapped Between Buildings
Valleys where two roofs meet hold drifted snow, and its melt runs along the wall into the lower building.

Commercial Roofing Planning for Pottsville Blocks
Six steps for a roof that shares water and walls with its neighbors.
Trace the Water Across the Block
Outlets, scuppers, and height changes are found on every connected roof so the full drainage path is clear before design.
Inspect Your Roof and Shared Walls
Coping, parapets, and party-wall flashing are checked from your side, with notes on what the neighbor's side needs.
Design Around the Connections
New roof height, outlet size, and edge details are set so your section drains well without pushing water next door.
Install and Flash the Section
Fresh insulation and membrane go on, then shared walls get flashing and counterflashing tied into the masonry.
Test the Outlets
Drains and scuppers are flushed and checked so water leaves the roof the way the drawing shows.
Share the Drainage Notes
You get a marked plan of outlets, walls, and the new roof height to share with neighboring owners who maintain the connected roofs.

Pottsville Commercial Roofing Questions
Shared drainage, neighbors, and getting a block roof inspected.
Question about your own roof?
Call UsShould a Pottsville commercial block share one roof drainage plan?
Where water crosses between sections, yes. Outlets, height changes, and ownership lines all go into the design, because replacing one roof can change the next roof's water route even when contracts and upkeep stay separate.
Do you take on commercial roofing for Pottsville businesses on joined buildings?
Yes. Storefronts, offices, and mixed-use buildings on a connected block are common jobs. We inspect your roof and the shared walls, and show you where your work affects the building beside it.
How can I get Pottsville commercial roofing near me inspected?
Call or send a message with the address and which walls or ceilings show water. We walk the roof, the parapets, and the outlets, then send a written scope. If neighbors share the drainage, we note which of their outlets and walls affect your section.
Is there a commercial roofing contractor near Pottsville for small block roofs?
Small roofs on connected buildings are often the hardest to drain, and we take them on. A compact roof between two taller walls can need more flashing work than its size suggests. Wall flashing on two or three sides, a single outlet, and tight access all land on a few hundred square feet.
Who pays when a leak comes through a shared wall?
That depends on property agreements between the owners, which we do not settle. We document where the water enters and which flashing failed, so both owners have the facts. The record includes photos of the wall, the flashing on each side, and where the stain appears inside.
Can one building on a block be reroofed while the neighbors keep their old roofs?
Plenty of blocks are reroofed one building at a time. The new roof has to tie into the old ones at shared walls without trapping water, so we flash each party wall to your side, keep outlets clear of the neighbor's roof, and record what condition their edge was in.
