About this service

Flashing is the metal seal where your chimney meets the roof, designed to keep water out of your home. If you see water stains on your ceiling near the chimney or notice damp insulation in the attic, your flashing may be compromised. Companies specializing in this repair remove the old sealant or metal, install new waterproof flashing, and ensure a tight bond. This is a critical repair to prevent long-term water damage to your home’s structure.

Summer is the quietest time for chimney work, making it the perfect opportunity to schedule repairs without the seasonal rush. Technicians have more flexibility to handle masonry work, cap installations, or flue liner replacements. Getting your maintenance done while the weather is dry ensures you are ready the moment the first chilly night arrives.
