Flashing and Crowns

Your chimney protects your home from the elements, but two of its most important parts often go unnoticed. The flashing and the crown are essential for keeping water out and preserving the strength of the brickwork. When either one starts to fail, leaks can spread quickly to your roof, attic, and interior walls. At Masonry Portland Maine, we repair and rebuild chimney flashing and crowns to ensure your home stays dry and secure all year long.

Water is one of the biggest threats to any structure. Once moisture enters the joints or the chimney base, it can freeze, expand, and cause cracking. Proper flashing and a well-built crown work together to stop that damage before it starts. Our team inspects, repairs, and replaces these components using proven methods and quality materials that last.

Chimney Flashing Repair and Replacement

Flashing is the metal barrier that seals the gap where the chimney meets the roof. Over time, flashing can rust, loosen, or separate from the masonry, allowing water to leak into the home. We inspect every layer of the flashing to locate weak spots or gaps. If repairs are possible, we reset or reseal the existing metal for a watertight finish. When flashing is too damaged to save, we replace it entirely using durable galvanized steel or copper for long-term protection.

Our team takes the time to shape and secure the metal properly to both the roof and the chimney. We seal every edge and overlap to ensure no water can work its way inside. Correctly installed flashing not only prevents leaks but also helps maintain the integrity of your roof and attic insulation.

Chimney Crown Repair and Rebuilding

The crown is the concrete or mortar cap that covers the top of the chimney. Its job is to direct water away from the bricks and mortar joints below. When the crown cracks or begins to crumble, water can seep into the masonry and cause serious deterioration. Our masons repair small cracks with strong, weather-resistant sealants or rebuild the entire crown if the damage is extensive.

We form new crowns with proper thickness, drip edges, and slope to allow water to run off smoothly. Each rebuild uses high-strength materials designed to resist the freeze and thaw cycles common in Maine’s climate. A solid, well-shaped crown extends the life of the entire chimney by keeping water out of the structure.

Waterproofing and Preventive Care

Repairing or replacing flashing and crowns is only part of a complete waterproofing plan. We also apply breathable masonry sealants that allow moisture to escape from inside the chimney while keeping rainwater out. This extra layer of protection helps prevent stains, cracking, and mold growth. Regular inspections and maintenance make it easy to catch small issues early before they turn into costly repairs.
