Leaks, seams and flashing
What Flat Roof Repair Includes
Most flat roof leaks start in a few predictable places: seams that have opened, flashing that has pulled away from a wall or curb, punctures from foot traffic and drains that no longer clear. We repair the source with new sealant, flashing, patches or membrane instead of covering up the symptom.
Before any repair we inspect the roof and use infrared leak detection to find moisture trapped under the surface, because the spot where water drips inside is often not where it gets in. All flat roof and rubber roof repairs are guaranteed in writing. We repair flat roofs in Boston and in Cambridge, Chelsea, Dorchester, Framingham, Medford, Newton, Somerville, Waltham, Woburn and Worcester.
Repair or replace?
A roof with a few problem spots is usually worth repairing. When the membrane is worn through in many places or keeps leaking after patches, replacement is the better call, and we tell you which one after a free inspection. See our EPDM rubber roof replacement page.

How we work
How We Repair a Flat Roof
Inspect
We walk the roof, check the seams, flashing, drains and penetrations, and scan for trapped moisture with infrared leak detection.
Repair
We fix the source: new sealant at seams, new flashing at walls and curbs, patches where the membrane is damaged, and drains that are cleared or repaired.
Explain
You get a plain-words recommendation after the free estimate, including when a replacement would make more sense than another repair.
