Roof and attic insulation in the Bronx
In a pre-war Bronx apartment building, most of the heat leaves through the roof and the top-floor ceilings. That is why top floors are cold in winter, hot in summer, and why boilers run long. In houses the attic is usually the biggest heat loss too.
Apartment buildings and row houses
- Through small openings: dense-pack cellulose fills the roof cavity and the ceilings stay finished.
- From below: closed-cell spray foam under the roof deck during a renovation.
- Bulkheads: we seal and insulate the stair bulkhead, a major leak at the top of the building.
Roof work is often the best first step for a larger building, and it can count toward Local Law 97.
Houses with a pitched attic
We air seal the attic floor and add blown-in insulation, or spray foam under the roof if the attic is used.
Incentives
The Bronx has Con Edison gas and electric. Buildings with 5 or more units may qualify for the Con Edison multifamily program, and one- to four-family homes may qualify for NYSERDA programs. We check what is open before we price the job.
Common questions
Can tenants stay during the work? Usually yes. We schedule around them and close off only the area we are working in.
