Commercial
roof repair.
A failing seam or a clogged drain does not mean a full tear-off. Crown finds the actual source, fixes it fast, and documents the repair so your warranty - and your building - stay intact.
Repair, not replaceFix the detail.
Fix the detail.
Save the roof.
Most commercial roofs fail at the details long before the field wears out - a seam lets go, a drain clogs, a length of flashing pulls away, mortar at the parapet crumbles. Caught early, each of those is a service call. Ignored, they turn into a tear-off.
Crown's repair crews work on the same flat and low-slope systems we install - TPO, EPDM, PVC, and modified bitumen - plus the slate, copper, and masonry on Boston's older buildings. We trace the leak to its actual source instead of chasing the stain, repair it with manufacturer-matched materials, and document the work so your warranty stays valid.
And when a repair is only buying time on a roof that is past its service life, we will tell you that too - and price a replacement alongside the fix so you decide on the numbers, not a sales pitch.
Masonry & Brick RepairBrick, mortar,
Brick, mortar,
and stone.
The roof is only as watertight as the masonry around it. Crown repoints, rebuilds, and reflashes the chimneys, parapets, and brickwork that fail right alongside the membrane.
Chimney repointing & repair
Deteriorated mortar joints are raked out and repointed with a matched mix, restoring the chimney's structure and stopping water from tracking down into the roof assembly below.
Parapet walls & coping
On a flat commercial roof the parapet is where masonry and roofing meet - and where leaks start. We repoint failing joints, reset loose coping, and reflash the wall-to-roof transition as one detail.
Brick restoration
Cleaning, resetting, and replacing spalled or water-damaged brick to keep the building envelope sound and the facade intact.
Stonework repair
Matching original material and technique to repair cracked, spalled, or dislodged stone on historic and modern buildings alike.

For an active leak, we aim to be on site within 24 hours. We'll identify the source of the leak, stop active water intrusion when possible, and recommend the appropriate repair. Call the office at 617-340-8886 and tell us what you are seeing.
We look at the roof's age, the membrane's remaining service life, and how widespread the problem is. A few isolated failures on an otherwise sound roof are a repair. Saturated insulation or field-wide breakdown is a replacement - and we price both so the call is yours.
Not when it is done correctly. We repair with manufacturer-matched materials and document the work, which is exactly what keeps single-ply and modified-bitumen warranties intact. Uncertified patchwork is what puts a warranty at risk.
Both. Chimneys, parapets, coping, and brick are part of the same watertight envelope as the roof. Repointing and reflashing the masonry at the same time as the roof repair is how you actually stop a recurring leak.
