Flat Roof Repair and Replacement
Flat roofs for rowhouses and brownstones
Look across almost any block in Brooklyn or Queens and you will see flat roofs. Rowhouses, brownstones and small apartment buildings mostly have low slope roofs that need different materials and different care from a pitched shingle roof.

Flat roof systems we work with
- Modified bitumen: a layered asphalt based system, common on NYC rowhouses.
- EPDM: a durable rubber membrane that handles heat and cold well.
- TPO: a white, reflective membrane with welded seams that helps keep the top floor cooler.
Flat roof problems we fix
- Ponding water that sits for days after rain.
- Blisters, cracks and open seams in the membrane.
- Failed flashing at parapet walls, bulkheads and skylights.
- Clogged or poorly placed drains and scuppers.
- Old layers that need to come off before a new system goes down.
We will look at the whole roof, including parapets, drains and flashing, and recommend the system that fits your building and budget. We explain the options plainly so you can choose.
Questions homeowners ask
Which flat roof material is best?
It depends on the building, the roof access and your budget. We explain the options at your free inspection and recommend what fits your roof.
Can a flat roof be repaired instead of replaced?
Often, yes. If the membrane is sound overall, a targeted repair can make sense. We will tell you honestly.
Do you work on attached rowhouses?
Yes. Shared walls and neighbouring roofs need careful flashing and tie ins, and we plan for that.
