what is problem?
Why Boston Chimneys Fail, and Why Waiting Makes It Worse
Chimneys are exposed year-round to rain, snow, ice, and temperature swings. Flashing rusts or pulls away, creating gaps where water pours into your attic. Mortar cracks. Bricks spall. Liners deteriorate. Caps loosen. Each issue worsens the others. A small leak becomes structural damage, mold, ruined insulation, and ceiling collapses. Insurance rarely covers preventable deterioration. The longer you wait, the more expensive it becomes. We catch these problems early.

Chimney Repair Methods That Actually Work
Surface patches fail. We find what caused the damage and eliminate it. Every repair is built to survive Boston winters.
Chimney Flashing Repair
Flashing is the metal seal where your chimney meets the roof, and it fails through rust, poor installation, or weather damage. We remove old flashing and install new material with proper overlaps and sealants to create a waterproof barrier that prevents water intrusion.
Brick Chimney Restoration
Brick chimneys deteriorate through cracked bricks, failing mortar, and spalling that compromise structure. We assess which bricks need replacement and repoint mortar joints with weather-resistant material using proper techniques that match your home’s original construction.
Chimney Crown Repair
The crown sheds water away from your flue, but cracks allow water directly into your chimney interior. We install new reinforced concrete crowns properly sloped for drainage and sealed at edges to prevent water pooling and seepage.
Chimney Liner Assessment & Repair
The liner protects your home from heat and combustion gases, and cracked liners are fire hazards that reduce efficiency. We use camera inspection to identify damage, then repair or replace the liner with modern durable materials.
Chimney Cap Repair & Installation
Missing or damaged caps allow water, birds, squirrels, and debris into your flue system. We install heavy-duty caps engineered to withstand Boston’s wind and ice while preventing entry points and improving draft efficiency.
Advanced Leak Detection
Water leaks often cause damage before they’re visible, hiding inside walls and attic spaces. We use thermal imaging, moisture meters, and camera inspection to pinpoint leaks and repair the actual source rather than just the symptom.
Chimney Mortar Repair
Deteriorating mortar joints allow water inside brick structures, which freezes and expands, destroying the brick. We remove deteriorated mortar and repoint joints with weather-resistant material to restore water resistance and structural integrity.
Complete Masonry Chimney Repair
Chimneys with multiple issues – cracked brick, loose stones, failing mortar, water damage – need comprehensive assessment. We evaluate the entire structure and replace sections as needed to ensure your chimney is solid, not just temporarily patched.

Reviews From Boston Clients
Our reputation is built on chimney repairs that actually work and customers who trust us again.
Sarah M.
"Water was actively dripping in our attic when I called. They came out the same day, sealed it temporarily, and had a permanent fix scheduled within 48 hours. Saved us thousands in potential damage."
David & Linda K.
"We've had our 1800s home inspected by other contractors who said the chimney was 'fine.' CAN Roof's drone inspection caught hidden mortar deterioration that would've failed within two years. Their honesty and expertise made all the difference. Worth every penny."
Michael P.
"After discovering brick damage, I was dreading the cost. Their inspection was thorough and transparent, they explained what absolutely needed fixing versus what could wait. The final bill was fair, the crew was respectful of our home, and the work is solid. We actually trust our chimney again."

FAQ
Chimney Repair Questions Answered
Water stains in your attic or near the chimney are the biggest red flag. Also look for white residue (efflorescence) on the exterior, cracked or missing mortar, loose or missing bricks, a damaged or missing cap, or visible cracks in the structure. Any of these warrant a professional inspection. Catching problems early prevents expensive structural damage.
Flashing is the metal seal where your chimney meets your roof. It sheds water away from the junction. When flashing fails, through rust, poor installation, or weather damage, water leaks into your attic and walls. Chimney flashing repair means replacing the old flashing and sealing it properly to create a waterproof barrier. This is critical because roof-to-chimney leaks cause serious water damage quickly.
Cost depends on what’s damaged and how extensive the repair is.The only way to know your actual cost is a professional inspection. We provide detailed written quotes with no hidden fees. Many homeowners’ insurance policies cover storm-related chimney damage, we help document and file the claim.
Repair makes sense when the chimney is structurally sound but has localized damage: flashing issues, mortar deterioration, cracked crown. Replacement becomes necessary when damage is extensive, structural integrity is compromised, or repairs keep failing. We assess your specific situation and explain the pros and cons of each option.
