Roof/Wall Seals in Buildings

Source

Investigation of construction details reveals that seals are virtually nonexistent at the junction of roofs and walls in commercial and school buildings of both past and current construction. Buildings with roof overhangs have greater problems than those with parapets or nonoverhanging designs. Various wall systems are utilized in conjunction with various roof systems, each reasonably serviceable in themselves, but the junction of two is badly neglected by designers and builders. Infiltration and exfiltration of hot and cold air at these junctions leads to the loss of large amounts of energy. Calculations of R-values are seriously in error due to lack of wind seals. Infiltration of rain water and the condensation that can form can appear to be roof and wall leaks. Methods are described to overcome this problem both in new and existing buildings, but primarily, the need to recognize and cope with the problem is described.
