The Challenge

Why a $X replacement
wasn't the answer.

The 68 Baldwin Street Condo Association in Charlestown was dealing with a 10,500 sq ft EPDM roof that had failed at the flashings and was leaking into multiple units during heavy rain. Ice and snow sliding off the sloped perimeter created a hazard for residents below. Tear-off and replacement quotes came back between $200,000 and $225,000 — a special assessment large enough that unit owners were threatening legal action over the repair costs.

The Process

Assessment to warranty
in A single mobilization.

01

Roof & Flashing Assessment

Evaluation of the existing EPDM membrane confirmed the failed flashings driving the leaks and established that the roof could be restored rather than replaced.

02

Surface Preparation & Flashing Repair

The membrane was cleaned and the failed flashing details were repaired and reinforced ahead of coating — no tear-off and no debris containers on a dense residential street.

03

GacoFlex Silicone Restoration

A GacoFlex silicone restoration system was applied as seamless waterproof protection over the existing roof. A gray silicone finish was specified in place of white to improve how the roof deck looks to the residents who overlook it.

04

Snow Guards & Warranty Registration

Snow guards were installed along the sloped perimeter to hold back sliding ice and snow, and the system was registered for a 20-year Gaco No Dollar Limit warranty.

Manufacturer Warranty

The association restored the roof for $134,660 against a $225,000 replacement quote, keeping roughly $90,000 out of a special assessment on unit owners. All previous leaks were eliminated, the falling-ice hazard was addressed with perimeter snow guards, and the building carries a 20-year Gaco NDL warranty. The gray silicone finish gave the residents overlooking the deck a roof that looks finished rather than utilitarian.
