About Flashing contractors

The purpose of flashings is to prevent the entry of water at areas on a roof where two components join together or intersect (i.e. one roof to another or a chimney thru a roof). Flashings can be constructed of galvanized steel, tin, aluminum, copper, lead or lengths of roll-roofing. The choice of flashing material will be dependent upon the construction of the roof and the material used for the roof covering.

Flashings will expand and contract, metal in particular, with heat from the sun and air temperature changes. They are also expected to move and stretch with typical building shifts. The areas where flashings are required are typically very vulnerable to water penetration. There is a high risk of water leakage and wood decay from a damaged, loose or poorly constructed flashing. For all of the above reasons, regular monitoring and routine maintenance of the flashing areas is essential to preventing leaks.
