The answer to 'which is better flashing repair or' is that flashing repair is generally better than full flashing replacement for most homeowners. Flashing repair involves fixing or replacing small sections of damaged flashing around chimneys, vents, or roof edges, while flashing replacement requires removing and replacing the entire flashing system. Flashing repair is usually faster, less disruptive, and more cost-effective than a full replacement.
Flashing repair can extend the life of your existing flashing by sealing cracks, holes, or loose areas. This helps prevent water leaks and protects your home's interior. Flashing replacement may be necessary if the flashing is severely corroded, damaged, or no longer functioning properly. However, this is a more extensive and expensive project that often requires roofers to remove sections of the roof.
