Flat & Commercial Roofing in New Haven

Common questions about flat & commercial roofing

How much does flat or commercial roof replacement cost in New Haven?

It varies a lot by system and building size, but most low-slope replacements run in the range of $6 to $12 per square foot installed, with EPDM on the lower end and multi-ply BUR or specialty coatings on the higher end. Repairs and coating jobs on an existing membrane are far cheaper, often a few hundred to a few thousand dollars depending on the extent of damage.

How often does a flat roof need to be replaced?

A well-maintained TPO or EPDM membrane typically lasts 20 to 25 years, while older BUR systems can go 15 to 20 years before a full recover or tear-off is needed. Coastal exposure, ponding water, and deferred maintenance shorten that lifespan considerably, which is why annual inspections matter.

What should a commercial roof inspection include?

A proper inspection checks the membrane for splits or blistering, flashing at every penetration and parapet wall, drain and scupper function, and signs of ponding water that hasn't drained within 48 hours. Interior water stains and rooftop equipment mounts are also worth flagging since they're common leak points.

How do I know if a roofing bid is high quality versus just cheap?

Compare whether each bid includes tear-off versus recover, insulation R-value and thickness, flashing detail work, and warranty terms (material-only versus workmanship-included). A bid that's noticeably lower usually skips one of these, so ask the contractor to itemize the scope before assuming it's the better deal.
