A stain near the chimney is a symptom, not a diagnosis. We trace the likely entry point and explain whether the roof connection, masonry or chimney top needs repair.

Repairs for older Boston homes
Want to know the cost before anyone visits your Boston home? Our flashing repair pricing page covers everything from resealing to full replacement and works out an estimate for your chimney. No email, no callback.
Chimney flashing seals the transition between the masonry stack and the surrounding roof. Brown Chimney assesses this connection on Boston homes where water appears near a chimney, roof deck or interior ceiling. The visible stain may be well away from the point where rain first entered.
The assessment considers damaged metal, open joints, failed sealant and the way the flashing integrates with roofing and masonry. Water can also come through a cracked crown or deteriorated brickwork, so those possible routes should be considered before the flashing is blamed.
Roof materials, slope and previous patches affect the repair plan. A compact rowhouse roof and a larger detached home may need different access arrangements. We explain the proposed work and any related roofing concerns before a repair is approved.
The chimney-to-roof connection inspected for water entry
A durable repair may require more than applying sealant over the exposed surface. The scope identifies whether selected sections can be repaired or whether the flashing arrangement needs replacement. Step flashing, counterflashing and other roof details are assessed in relation to the actual chimney and roof.
If opening the area reveals damaged decking or roofing, that condition needs a documented scope and price. The finished repair is photographed so you can see the work that is otherwise difficult to view. Interior stain treatment follows resolution of the leak and is a separate finishing task.
If the source lies higher up, see chimney crown repair and cap installation. Masonry waterproofing may help suitable sound masonry after defects are repaired.
Note when the moisture appears and how long it lasts. Rain-related patterns, previous roof work and photographs can help explain the problem when you arrange the assessment.
We assess the relevant chimney and roof components, explain the likely source and agree on a repair scope. Access, any opening-up work and the planned finished roof condition are confirmed before work begins.
01
Water stains rarely start where they show. We trace the actual entry point — flashing, crown, cap, or masonry — before quoting anything, because sealing the wrong spot solves nothing.

02
You approve the exact price before anything is lifted. Chimneys wider than 30 inches at the roofline need a cricket by code — if yours does, that's identified and priced up front.
03
Failed flashing and hardened sealant come off down to sound roof deck. Any pre-existing shingle damage is documented and quoted separately rather than quietly absorbed.
04
Step, counter, and saddle flashing set in aluminum or lead-coated copper — never plastic, never rubber — and sealed with chimney-rated elastomeric caulk.
05
The roof area around the chimney base is restored, the work photographed before and after, and the labor covered by the 1-year workmanship warranty.

Our first chimney cleaning for our wood stove and could not have asked for a better, swifter and quality experience. Many thanks to the Brown Chimney team.

A flashing quote should identify the metalwork and roof integration included in the repair.
Damaged decking, broad roof replacement and interior finishing are separate unless explicitly listed.
Crown, cap and masonry defects may need their own repair; waterproofing alone does not replace failed flashing.
Call Brown Chimney at 781-547-7784 or book a Boston leak assessment. Explain where and when water appears so we can plan the inspection and quote the appropriate repair.
