Client: Boston Trinity Academy
Project Location: Boston, Massachusetts
Project Size: 32,000 SF
Project Type: Roof Replacement

Scope:

The existing ballasted go-over EPDM roof system was experiencing significant water infiltration. A photovoltaic solar array which had been previously installed was reportedly fastened through the existing roofing system which was contributing to the on-going leaks. A built-up roof (BUR) system roof was below the go-over system on a lightweight concrete deck which required hazardous material abatement. A new PVC roof was installed followed by a new photovoltaic solar array.

Services:

• Prepared construction documents and oversaw the roof restoration

• Remove all existing materials down to the top of structural deck (including the BUR and lightweight fill). Hazardous material testing and abatement was required due to unexpected conditions.

• Provide new, code-compliant single-ply PVC roof, including vapor retarder on top of the concrete slab and a code compliant adhesively attached polyisocyanurate insulation

• Remove and replace roof drains with 4’x4’ sumps

• Extend vent pipes

• Extend exhaust fans and other rooftop mechanical equipment based on new roof height

• Extend curbs/replace unit skylights

• Penthouse wall backup wall infill repairs

• New masonry through wall flashing installation at penthouse walls

• New PV array installation once roofing was completed
