Flashing & Leak Repair in Ann Arbor, MI

Chimney flashing and leak repair is the process of diagnosing and correcting the points where your chimney meets your roof — the metal barrier system that keeps water from entering your home at that junction. Ann Arbor Chimney Repair offers this service to homeowners in Ann Arbor, Michigan who are seeing water stains, damp walls near the fireplace, or ceiling damage they can't trace to a clear cause. If you've noticed these signs after a rainstorm or during the spring thaw, you're in the right place. Done correctly, flashing repair stops the intrusion at its source and protects the surrounding masonry, framing, and interior finishes from compounding damage.

What This Service Involves

A flashing and leak repair job begins with a thorough inspection of the chimney from both the roof and the interior — the flashing itself, the chimney crown, the mortar joints, and the area where the flashing is embedded into the masonry. The crew identifies whether the problem is a failed sealant joint, corroded or lifted metal, improper original installation, or damage to the chimney crown that's allowing water in from above. Repair work typically includes resecuring or replacing the flashing panels, resealing all joints with appropriate materials for the freeze-thaw conditions Michigan delivers, and addressing any minor masonry deterioration directly connected to the leak. You don't need to move anything or prepare the roof yourself — the crew brings all materials and handles everything from access to cleanup.

When You Need Flashing & Leak Repair in Ann Arbor

The most common trigger is water stains appearing on the ceiling or wall near your fireplace, especially after a heavy rain or when snow on the roof starts melting. You might also notice a musty smell inside the firebox, efflorescence (white mineral deposits) on the exterior masonry, or deteriorating drywall near the chimney chase. Some homeowners call after a home inspection flags flashing separation before a sale or purchase. Flashing & leak repair in Ann Arbor is also frequently needed after ice dam seasons, when the freeze-thaw cycle has worked existing gaps wider over several winters. If the leak is small now, it rarely stays that way — water finds the path of least resistance and widens it.

Why These Problems Happen

Flashing fails for a few predictable reasons. The metal separates from the masonry because mortar joints around the embedded edge deteriorate over time, especially in Ann Arbor's climate where freeze-thaw cycles put constant stress on the chimney's exterior. Older homes throughout Ann Arbor's established neighborhoods — many built with aluminum or thin galvanized flashing that has a shorter service life — are particularly vulnerable. Poor original installation is also common: flashing that was surface-sealed rather than properly embedded into the mortar will fail within a few years regardless of material quality. Once water gets behind the flashing, it accelerates the mortar's breakdown, making each subsequent season worse than the last. DIY sealants don't address the separation at the masonry level, so they provide only temporary relief.

What Affects the Cost

Several factors shape the scope of a flashing repair. The size and configuration of the chimney matters — a single-flue chimney on a simple gable roof involves less flashing area than a wide double-flue chimney on a complex hip roof. The type of metal required plays a role, since some roof materials and chimney configurations call for heavier or more specialized flashing. If the chimney crown is also damaged and contributing to the leak, that work adds to the scope. Roof pitch and height affect how much time and equipment safe access requires. Finally, if the surrounding masonry has deteriorated beyond the immediate flashing area, that additional repair work will be factored into the consultation. The right approach is to assess all of this on-site before any number is discussed.

What to Expect from Quote to Cleanup

The process starts when you call or reach out to schedule an inspection. A technician comes to your home, gets on the roof, and examines the flashing, crown, and connected masonry in person — photos can help confirm an appointment but don't replace the on-site assessment. After the inspection, you receive a clear explanation of what was found, what needs to be done, and why. Once you approve the scope, the repair is scheduled and completed in most cases in a single visit. At the end of the job, the crew removes all debris and old materials, and a technician walks you through what was done so you know exactly what changed and what to watch for going forward.

Repair vs. Replacement

Not every flashing problem calls for a full replacement, and not every repair is worth attempting on badly degraded material. If the existing flashing is intact, properly embedded, and the leak traces to a failed sealant joint or a single lifted section, repair is the right call — it addresses the problem without unnecessary work. Replacement becomes necessary when the metal has corroded through, when the original installation was never correctly embedded into the masonry, or when the flashing has shifted so far out of position that it can't be resecured reliably. A partial replacement — addressing one side or the step flashing along a roofline — is also sometimes the right middle ground. The on-site inspection is what makes that determination; there's no way to know from the outside which situation you're dealing with until the flashing is examined up close.
