Chimney Repair in Chatham, NJ | Monarch Roofing & Construction

Most of Chatham Borough was built out before World War II, and its streets, from the Main Street downtown to the homes climbing Long Hill along Fairmount Avenue, are full of pre-war houses with masonry chimneys. Those chimneys have outlasted several roofs, and in many cases the flashing around them has been patched with tar again and again rather than replaced. Tar buys a season or two, then cracks, and the leak returns. Behind finished attic walls and knee walls, that water can go unnoticed for a long time.

Monarch Roofing & Construction repairs chimneys across Chatham Borough with the care older homes need. We replace patched flashing with properly installed metal, repoint with mortar compatible with older brick, rebuild crowns, install caps, and rebuild chimneys above the roofline when the masonry is beyond saving. We start with a free chimney repair estimate.

Our chimney work covers the exterior masonry and the roof junction:

• Back pans and crickets on the uphill side of the chimney
• Repointing deteriorated mortar joints
• Replacing cracked and spalling brick
• Repairing or replacing crowns
• Installing and replacing chimney caps
• Partial and full rebuilding above the roofline
• Repairing board decking and roofing around the chimney

The Problem With Tar-Patched Flashing

On many pre-war homes, the chimney flashing has been “repaired” by coating it with roofing tar or caulk. It looks like a fix, and for a little while it acts like one. But tar does not move with the chimney and roof as temperatures change. It hardens, shrinks, and cracks, and once it opens up, water runs behind it and into the house. Layers of tar also hide what is underneath, which may be rusted step flashing, loose counter-flashing, or no flashing at all.

A proper repair removes the patches and the old metal. Step flashing is installed with each course of shingles up the sides of the chimney. Counter-flashing is set into a cut in the mortar joint and folded down over the step flashing. The low side gets an apron, and the high side gets a back pan or cricket. Done this way, the flashing sheds water mechanically without depending on sealant.

Finished Attics and Hidden Leaks

Many older Chatham homes have finished attics or rooms tucked under the roof. When a chimney leaks into a space like that, water can run behind knee walls and plaster before it shows. Signs to watch for include stains or bubbling paint on walls near the chimney, a musty smell, or soft spots in the plaster. If you notice any of these, the chimney flashing and masonry are worth checking even if you have not seen a drip.

Brick and Mortar Repair

Pre-war chimneys were typically built with softer brick and mortar than today’s materials. When we repoint, we use mortar that is compatible with that older brick. A mortar that is too hard can crack the brick faces as the chimney expands and contracts with the seasons.

Repointing means removing deteriorated mortar to a sound depth and filling the joints with fresh mortar in layers, tooled to match. Bricks that are cracked or spalling, with faces flaking or breaking away, are cut out and replaced with brick matched as closely as practical. When spalling is extensive, we look for the water source, typically a failed crown or open flue.

Crowns and Caps

A chimney crown covers the top of the masonry. A good one is solid, slopes away from the flue, and overhangs the brick with a drip edge. Many older chimneys have thin mortar crowns that have cracked through. We repair minor cracks and replace crowns that are failing.

A cap covers the flue to keep out rain, snow, animals, and debris. We install caps on uncapped chimneys and replace those that are rusted or damaged.

Rebuilding Older Chimneys

When the masonry above the roof is loose or crumbling across many courses, leaning, or so heavily patched that little sound brick remains, rebuilding is often the most durable option. We take the chimney down to solid masonry and relay it, either partially or fully above the roofline, then finish with a new crown, cap, and flashing. We match the brick and mortar to the house as closely as practical and recommend a rebuild only after evaluating the chimney.

Staging on Hillside Streets

Homes on slopes, such as those along streets climbing Long Hill, can be harder to stage for chimney work. We plan ladder and material placement, debris removal, and protection for landscaping before the job starts.

Breathable Waterproofing

Once repairs are complete, a breathable water repellent can reduce how much rain older brick absorbs while allowing moisture vapor to escape. It is a finishing step, not a fix for flashing, crowns, or open mortar joints.

Signs Your Chimney Needs Repair

• Tar or caulk smeared around the base of the chimney
• Stains or bubbling paint on walls or ceilings near the chimney
• Musty smells in finished attic spaces
• Recessed, crumbling, or cracked mortar
• Flaking, cracked, or loose brick
• A cracked crown or missing cap
• White deposits on the brick
• Debris from the chimney on the roof
• A visible lean

Repair Versus Rebuilding

Repair is the starting point for older chimneys, because preserving sound masonry is usually worthwhile. When damage is too extensive for repairs to hold, rebuilding the affected section is more durable. We explain what we found and why we recommend each approach.

What Affects Chimney Repair Costs in Chatham?

• How much tar and old flashing must be removed
• Repointing and brick replacement scope
• Crown repair or replacement
• Whether a cricket is needed
• Chimney height and roof pitch
• Board decking damage near the chimney
• Staging on sloped lots
• Partial or full rebuilding

Permits for Chimney Work in Chatham

Permit requirements depend on the type of chimney work. Rebuilding a chimney or other structural masonry work may require a construction permit and inspection under New Jersey’s Uniform Construction Code, while some minor exterior maintenance may not. Because the answer depends on the scope of the job, check with the Chatham Borough construction office before work begins, and we can discuss it during your estimate.

Someone tarred my chimney flashing last year and it still leaks. Why?

Tar cracks as it ages and does not replace missing or corroded flashing underneath. The lasting fix is new flashing installed in layers with the shingles.

Can you repair flashing without redoing the whole roof?

Usually, yes. We remove and replace shingles around the chimney. If the roof is near the end of its life, we will let you know.

I have a finished attic. How would I know if the chimney is leaking?

Look for stains, bubbling paint, soft plaster, or a musty smell near the chimney.

Is Chatham Borough different from Chatham Township for permits?

Yes. They are separate municipalities with their own construction offices.
