Lead flashing is an essential component of any roofing system, as it helps to prevent water from penetrating the roof and causing damage to the underlying structure. Installing lead flashing requires skill and expertise, which is why a professional roofing contractor typically does it. The process begins by cutting the lead flashing to the appropriate size and shape, considering the roof’s contours.    The flashing is then bent to fit the unique angles and curves of the roof and secured in place using roofing nails or other fasteners. Proper installation of lead flashing is crucial to the long-term durability and effectiveness of a roofing system and should always be entrusted to a qualified professional.
