Chimney Flashing Repair in Portland, ME
Salt air and severe coastal Nor'easters destroy metal flashing. Learn the realistic 2026 costs for repairing or replacing chimney flashing on Portland homes....
Expert sealing and structural repair of the most vulnerable points on your roof: chimneys, skylights, vents, and roof valleys.
Because gravity naturally forces water into roof valleys and around chimneys, flashing failures account for over 80% of all residential roof leaks. When these metal joints fail, water pours directly into your wall cavities, silently destroying drywall, rotting framing, and creating severe electrical hazards.
Depending on the severity of the failure, our local experts will either apply advanced polyurethane sealants to minor cracks or completely excavate and replace the rusted metal step-flashing. We ensure the new metal is properly layered beneath the shingles to aggressively redirect heavy water flow away from the vulnerability.
Flashing leaks never get better on their own. The longer you wait, the wider the gap becomes. Seal the leak today.
Carefully pulling back the shingles surrounding the chimney or valley to expose the damaged or rusted metal flashing.
Removing compromised metal and installing custom-fabricated, heavy-gauge replacement flashing designed to outlast the weather.
Properly weaving the new metal with premium ice-and-water shields and your existing shingles to ensure a watertight seal.
The leak is almost always occurring at the 'step flashing'—the thin pieces of layered metal that bridge the vulnerable gap between the slanted roof deck and the vertical brick wall.
While the metal flashing itself can last decades, the sealants and caulking used around it endure extreme thermal shock. They often dry out, shrink, and crack within 7 to 10 years, requiring professional maintenance.
