Exterior Roof Spray

For this 1930s-built house, a re-roof allowed our crew of trained professionals to spray down into the roof joists from above.

The Foam Comfort Crew, along with the careful coordination of a highly skilled roofing crew, allowed the two trades to work seamlessly to prepare the area for insulation, install a 2lb spray foam insulation solution and then close, seal and shingle the roof.

All old homes built in this area had minimal to no insulation in the roofline and attic areas often involved knee walls and dormers, further adding to the complexity.

Once the old roof was removed, a cardboard baffle was secured in the joist cavity and then a 2lb medium-density spray foam insulation was applied. The 2lb foam is a vapor barrier and will not allow any condensation to form in the roof cavity below as it provides a monolithic barrier.

Removing the lathe and plaster from the interior is a major and totally disruptive endeavor, so using an exterior method to insulate, such as what was done in this scenario, can significantly reduce the mess and inconvenience to the inhabitants.
