The answer to 'how to install flashing' is to properly install flashing around roofing penetrations, edges, and transitions to prevent water leaks. Flashing is a thin, impermeable material like metal or plastic that is used to divert water away from vulnerable areas of the roof. Proper flashing installation is crucial for maintaining a watertight roof system.
To install flashing, first clean and prepare the surface where the flashing will be placed. Apply a layer of roof sealant or adhesive, then press the flashing firmly into place. Secure the flashing with roofing nails or screws, overlapping seams by at least 2 inches. Finally, apply another layer of sealant over the edges of the flashing to create a waterproof seal.
