Know Your Roof Penetrations
Roof Penetration Sealant Systems | H.B. Fuller
The reasons for roof penetrations are numerous: roof vents, electrical conduit, utility pipes, satellite dishes, HVAC curbs, lightning protection. Where possible, flashings should extend a minimum of eight inches above the finished roof surface. In the past, using pitch pockets or pitch pans around penetrations was a common practice, especially on modified bitumen and built-up roofs. This method involved installing a 2-inch high flanged open-top metal box placed around the penetration, mechanically fastening it to the roof and filling it with non-shrink grout. Pourable bituminous or polymeric sealant is added on top and built up sloped so water runs down and away from the penetration.
Roof Penetration Flashing
E-Curb penetration seals replace old-style metal pitch pans with versatile, precast components and pourable sealants. E-Curbs are designed for use on granulated modified bitumen, asphalt and coal tar B. E-Curbs are highly versatile for sealing penetrations around solar panel mounts, HVAC, Electrical, Pipes, and any type of structural supports. When installed properly, this system forms a durable, waterproof rubber seal around penetrations.
On the surface, the idea of adding equipment to a roof without penetrations sounds pretty good. Keep reading to see why this may be the wrong approach It is understandable that people hate roof penetrations and try to avoid them at all cost. But instead of simply avoiding roof penetrations altogether, consider that if done properly, those painful leaks can be eliminated and rooftop equipment can be mounted securely.
