The answer to 'flashing repair or flashing repair' is that flashing repair and flashing replacement are two different approaches to addressing issues with roof flashing. Flashing repair involves fixing or patching existing flashing, while flashing replacement involves completely removing and replacing the flashing.
Flashing repair is generally a more cost-effective option and can be a good choice if the flashing is only moderately damaged. It involves sealing cracks, holes, or gaps in the flashing to prevent leaks. This can be done with a sealant or by installing new pieces of flashing over the old ones. Flashing repair is a relatively simple DIY project for experienced homeowners, but it's important to ensure the repair is properly sealed to prevent future issues.
