Flat Roofing in Greenwich, Connecticut

The flat and low-slope roofs in Greenwich face a special challenge: the water and the snow have nowhere to go without the pitch. Flat roofing in Greenwich means the TPO, the EPDM, and the modified bitumen systems built with the right drainage, the proper seams, and the membranes that handle the snow load and the freeze-thaw.

The flat roof is a different animal from the pitched roof, and it needs a different eye. The water has no gravity to help it, so the drainage, the seams, and the flashing do all the work. In Greenwich, the flat roof also carries the snow load and the ponding meltwater, so the membrane and the structure have to be right.

Signs Your Greenwich Roof Needs Flat Roofing

• Ponding water that lasts for days after a rain or a thaw
• Blisters or bubbles in the membrane – the moisture is trapped
• Cracked or alligatored surface – the UV and the freeze-thaw are at work
• Leaks at the seams and the flashings – the winter stress has opened the joints
• Standing ice on the roof in the winter – the drainage is blocked
• The roof membrane is separating from the flashing at the edges

Why Greenwich Roofs Need Flat Roofing

The Greenwich winter is the flat roof’s hardest season. The snow and the ice sit on the flat surface, and when the meltwater refreezes at the seams, the expansion stresses the membrane. The ponding water then freezes and thaws, working the seams and the flashing loose over the years.

The summer is the second challenge. The heat and the UV age the membrane, and the humid air feeds the algae on the flat surface. The right system – the TPO for the heat reflection or the EPDM for the cold flexibility – plus the proper drainage and the regular maintenance, is what keeps a flat roof alive in Greenwich.

The flat roof’s weakness in Greenwich is the winter freeze. The meltwater ponds on the surface, freezes at the seams, and expands to open the joints. The right membrane – the TPO, the EPDM, or the modified bitumen – and the clear drains keep the water moving before it can freeze and do the damage.

The flat roof also needs the seasonal care that the pitched roofs do not. In Greenwich, the flat surface collects the leaves in the fall and the snow in the winter, and both have to move. We build the drainage into the design – the crickets, the tapered insulation, and the clear drain paths – so the water never sits long enough to freeze and damage the membrane.

How We Do Flat Roofing in Greenwich

1. Inspect the roof and the structure – check the deck, the drainage, and the existing membrane
2. Prepare the surface – clean, repair, and prime the substrate
3. Install the membrane – the TPO, the EPDM, or the modified bitumen
4. Flash the penetrations and the edges – the vents, the drains, and the parapets
5. Verify the drainage – the water moves to the drains and the ponding is gone
6. Inspect and document – the final check and the warranty paperwork

Preventing Problems in Greenwich

• Keep the drains and the scuppers clear – the snow and the debris block the flow
• Check for the ponding after every thaw – the standing water is the enemy
• Inspect the seams each spring – the freeze-thaw opens the joints
• Clear the snow off the flat roof when it piles up – the load and the ice are the risks
• Clear the snow off the flat roof when it piles up – the load adds up
• Check the roof drains before every freeze – the clear path is the winter survival

On a Greenwich flat roof, the drainage is everything. A roof that drains in hours instead of days avoids the ponding that freezes, expands, and tears the seams apart every winter.
