77 Bishop Allen Dr
Low-slope PVC roofing with vent flashings, equipment-curb details, and perimeter transitions.
Project overview
At 77 Bishop Allen Drive in Cambridge, the roof photographs show a white PVC membrane field with several existing rooftop features. The overview follows the roof edge and vents, while the second view shows equipment-curb flashing and a walkway pad along the perimeter. Together, the views show the relationship between the open roof field and the details around it.
Roof details
- White membrane roof field and perimeter transitions.
- Flashed roof vents and other penetrations.
- Equipment-curb flashing and a walkway pad beside rooftop equipment.
Give existing rooftop features their own scope
Equipment curbs, vents, and roof edges each need a defined transition to the roofing system. A proposal should identify those flashing details and distinguish roofing work from any separate equipment repairs, with responsibilities clearly assigned.
