Flashing is the material used to waterproof a roof around any projections through the roof deck. 90% of all roof leaks originate at flashings. Flashings are the most vulnerable part of any roof, and many roof problems are actually flashing problems. Leak Enders is able to detect and repair most flashing concerns, including step-flashing. These are metal flashing pieces installed at side-walls and chimneys for weather proofing. Our roofers are also experienced with counter-flashing, which is the metal or siding material that is installed over roof-top base flashing systems.
