Chimney Repair in Hanover Township (Whippany & Cedar Knolls), NJ | Monarch Roofing & Construction

Hanover Township’s two communities, Whippany and Cedar Knolls, grew largely after World War II, when the old iron and paper mill township became a suburb. Many homes from that era are now on their second or third roof, and some have had new layers of shingles added over old ones. Each of those roofing jobs touched the chimney flashing, and not always for the better. Add mature trees and Morris County freeze-thaw winters, and a lot of postwar chimneys are due for attention.

Monarch Roofing & Construction repairs chimneys throughout Whippany and Cedar Knolls. We trace chimney leaks, replace flashing, repoint mortar, replace brick, rebuild crowns, install caps, and rebuild chimneys above the roofline when the masonry is beyond repair. You can start with a free chimney repair estimate.

Chimney Repair in Whippany and Cedar Knolls

A chimney does its job quietly until something gives. On postwar homes, the usual weak points are predictable:

• Flashing that has been reused, buried under extra shingle layers, or covered in roofing cement during past re-roofs
• Mortar joints eroded by decades of rain and freezing
• Crowns built as a thin layer of mortar that has since cracked
• Missing caps that let rain fall straight into the flue
• Brick at the top courses loosened by water and frost

Our chimney services cover each of these:

• Exterior leak diagnosis at the chimney and roof junction
• New step flashing, counter-flashing, aprons, and back pans or crickets
• Repointing and brick replacement
• Crown repair or replacement
• Cap installation and replacement
• Partial and full rebuilding above the roofline
• Repairs to the shingles, underlayment, and decking around the chimney

Layered Roofs and Chimney Flashing

When a new layer of shingles goes over an old one, the existing chimney flashing is often left in place and simply sealed over, or the new shingles are butted against the chimney with a bead of cement. That shortcut tends to fail within a few years. The cement shrinks and cracks, the old metal underneath may already be corroded, and water finds its way in.

Correct chimney flashing has distinct layers. Step flashing is woven into each shingle course along the sides. Counter-flashing is cut into a mortar joint and folded over the step flashing. An apron covers the downhill face, and a back pan or cricket handles the uphill side. When we repair flashing, we strip the roofing back around the chimney, check the decking, and install new metal in that sequence. If your roof is near replacement anyway, we will tell you, since the best time to re-flash a chimney is during a full tear-off.

Additions and Chimney Leaks

Many Hanover Township homes have been expanded over the years. When an addition changes the roofline, a chimney that once sat in the middle of a simple slope can end up near a valley or at the bottom of a longer run of roof. More water reaches it, and flashing that was adequate before may no longer keep up. We look at how water flows toward the chimney across the whole roof and recommend upgrades, such as a cricket, where they make sense.

Mortar Repointing and Brick Repair

Mortar joints are designed to wear before the brick does. After decades, they recede, crack, and crumble, letting water soak into the chimney. In winter that water freezes and pushes the joints further apart. Repointing removes deteriorated mortar to a sound depth and replaces it with new mortar compatible with your brick, tooled to match.

When bricks are cracked through or spalling, with faces flaking or breaking away, we cut them out and set replacement brick. Widespread spalling usually means water is entering from above, and we correct the source at the same time.

Crowns and Caps

Crown repair and replacement

A crown sheds water off the top of the chimney. Done well, it is a solid, sloped slab that overhangs the brick with a drip edge. Done poorly, it is a thin layer of mortar that cracks in the first few winters. We repair minor cracks in sound crowns and replace crowns that are broken or deteriorated.

Chimney caps

A cap keeps rain and snow from falling directly into the flue and keeps out birds, animals, and debris from nearby trees. We install caps on uncapped chimneys and replace those that are rusted or damaged.

Rebuilding Above the Roofline

When the brick above the roof is loose across many courses, the chimney is leaning, or patching has left little sound masonry, rebuilding is often the durable option. We take the chimney down to solid masonry and relay it, then install a new crown, cap, and flashing. Depending on the condition, this might be a partial rebuild of the upper section or a full rebuild above the roofline. We only recommend it after evaluating the chimney.

Waterproofing After Repairs

A breathable water repellent can help repaired masonry resist rain absorption without trapping moisture inside. It is a finishing step for chimneys where it is appropriate, never a substitute for fixing flashing, crowns, or mortar.

Signs Your Chimney Needs Repair

• Water stains near the chimney on ceilings or walls
• Flashing covered in tar or caulk
• Eroded, cracked, or crumbling mortar
• Cracked, loose, or flaking brick
• A cracked crown or missing cap
• Masonry debris on the roof or in gutters
• White deposits on the brick
• Damp wood around the chimney in the attic
• A chimney that leans

Repair Versus Rebuilding in Hanover Township

If the masonry is mostly sound, repair is the practical choice: new flashing, repointing, and crown work can restore a postwar chimney for many years. If deterioration runs deep or the chimney has shifted, rebuilding the affected portion is usually more durable than repeated patching. We explain our findings and why we recommend one approach.

What Affects Chimney Repair Costs in Hanover Township?

• Number of roofing layers around the chimney
• Extent of repointing and brick replacement
• Crown repair or replacement
• Flashing replacement and cricket construction
• Chimney height and roof pitch
• Deck damage from past leaks
• Partial or full rebuilding

Permits

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 Hanover Township construction office before work begins, and we can discuss it during your estimate.

Hanover Township Chimney Repair FAQs

Do you offer free chimney repair estimates in Whippany and Cedar Knolls?

Yes. We provide free chimney repair estimates throughout Hanover Township.

How do I schedule?

Use the scheduling button on this page or call or text (551) 241-0470.

My roof has two layers. Does that affect the chimney flashing?

Often, yes. Flashing on layered roofs is frequently sealed over instead of being replaced. We remove the roofing around the chimney to install new flashing correctly.

Should I replace chimney flashing when I replace my roof?

Yes. A full tear-off is the ideal time to install new flashing, and we include it in our roof replacements.

Can you repair just the crown?

Yes, if the rest of the chimney is sound. We check the brick and mortar below to make sure the crown repair will not be undermined.

Does an addition change how my chimney handles water?

It can. If the new roofline sends more water toward the chimney, it may need upgraded flashing or a cricket.
