Image
A roof drain is installed in an existing flat roof retrofitted with above-deck rigid foam insulation that is integrated with new air and water control layers
Image
Closed-cell foam is sprayed into roof cavities along the masonry parapet wall to form a continuous air barrier between the wall and the sheathing of the flat roof
Image
Closed-cell spray foam fills the roof joist cavities forming an air barrier between the masonry parapet wall and the roof sheathing
Image
Existing low-slope (“flat”) roof and brick masonry walls with a new fully adhered air barrier membrane plus polyisocyanurate rigid foam insulation and a roofing membrane water control layer
Image
Polyisocyanurate rigid foam insulation is installed in multiple layers with staggered, taped seams over the flat roof
Image
Provide flashing and sealing integrated with the air and water control layers for vents and other roof penetrations
Image
Retrofit an existing roof by installing rigid foam, new moisture and air control layers, new sheathing, and new cladding plus cavity insulation in the roof rafters to create an unvented attic
Image
Right - These roof insulation panels are installed in multiple layers with joints offset both vertically and horizontally. The plywood nail base fastened to the roof framing holds the insulation layers together snuggly thus minimizing gaps
Image
Roofing membrane is installed over polyisocyanurate rigid foam insulation and insulation cover board that has been cut to fit around locations for blocking for the PV system rack
Image
Roofing paper protects the top of the new plywood parapet while the base of the parapet is air sealed with spray foam and fibrous insulation is installed in the rafter cavities in this flat roof retrofit
Image
The base of the plywood parapet is air sealed with spray foam and fibrous insulation is installed in the rafter cavities in this flat roof retrofit
Image
The retrofitted flat roof has PV panels and walking mats installed over the roofing membrane
Image
The wood blocking for future PV panel installation extends above the surface of the top layer of polyisocyanurate rigid foam insulation installed as part of a flat roof retrofit
Image
Water management details for a roof drain installed along with rigid foam on a flat roof
Image
Wood blocking for future PV panel installation is installed in the layers of polyisocyanurate rigid foam insulation during a flat roof retrofit
Image
Wrong - The roof insulation panels for this building were not installed in multiple layers with joints offset. The snow melt pattern shows thermal bypasses at the insulation panel joints.
Image
Wrong: Closed-cell spray foam roof insulation was not thick enough to meet IRC levels so the foam surface is colder than the dew point of the interior air and condensation formed on surface of the foam
