What Homeowners Should Check Around Their Chimney Before Winter

August 13, 2026
Chimneys

During winter, there is cold weather, rain, snow, ice, and windy conditions, which reveal the weaknesses surrounding your chimney and roof. Therefore, homeowners should consider scheduling a chimney inspection Before Winter. Early inspections can identify small issues that, otherwise, can develop into costly repairs. Since your chimney connects to your roofing system, any weakness in flashing, shingles, masonry or sealants creates an entry point for water into your home. In New Jersey, homeowners should look at the above-mentioned areas before the coming of severe winter weather conditions.

Why Schedule a Chimney Inspection Before Winter?

Your chimney experiences changes in weather throughout the year. But winter weather conditions may intensify any damage that already exists in your chimney. Cold weather increases chances of expansion of the moisture found within cracks. Snow and rain penetrate through the weak flashing or masonry. A professional inspection of your chimney can identify:

  • Cracked masonry: Small cracks allow moisture to penetrate into your chimney. And such cracks may increase due to the freeze and thaw cycle.
  • Damaged flashing: Such problems may include loose flashing, cracks, or corrosion allowing water into the roofing system.
  • Deteriorated mortar: It reduces masonry’s strength making it easier for moisture to penetrate into the chimney.
  • Damaged chimney caps: The cracks, loose sections, or damage screens allow rain, snow, leaves, and other debris to penetrate into your chimney.
  • Roofing damage: Missing or damaged shingles around your chimney act as other entry points for water.
  • Interior moisture: The ceiling stains, damp insulation, and musty odor show that water already infiltrates into your house.

Finding such problems early allows homeowners to prepare repairs.

Follow a Chimney Inspection Checklist

The use of Chimney Inspection Checklist is essential during preparing your house before the coming of winter. First, you should start by examining the exterior chimney structure. That includes looking for cracks, loose bricks, deteriorated mortar, and discoloration. Next, you should inspect the area of the connection between the chimney and the roof since damage of flashing in this area allows water to penetrate into the roofing system.
Your list should have the following items:

  • Chimney masonry: Cracked bricks, loose parts, deteriorated mortar, and other deterioration that may worsen in winter.
  • Flashing: Gaps, lifting, rust, corrosion, and deteriorated sealants in the chimney-roof connection.
  • Chimney cap: The cracks, loose parts, damage screens, and other openings allowing moisture into your chimney.
  • Roof shingles: The missing or damaged shingles around your chimney.
  • Attic area: The presence of water stains, damp insulation, and moisture around the chimney penetration.
  • Interior ceilings: The stains, peeling paint, or other signs of moisture on the ceiling.

Homeowners should avoid climbing onto steep or slippery roofs. A professional can safely inspect difficult-to-reach areas.

Inspect the Chimney Flashing Carefully

The chimney flashing forms a waterproof layer protecting the area of the connection between your chimney and the roofing materials. Damaged flashing may allow water into the roofing system.

During your inspection, look for:

  • Lifted or loose sections at the chimney base.
  • Rust or corrosion of metal flashing.
  • Cracks or gaps in the sealing around the chimney-roof connection.
  • The separation of flashing from masonry.
  • The stains of water inside the attic near the chimney.
  • Damaged shingles near the flashing.

Do not ignore even the smallest problems with flashing because they may allow repeated water exposure and may eventually damage your roofing materials or interior structures. Professional chimney repair services can help you to solve problems with flashing before winter.

Look for Signs of Chimney Leaks

The prevention of chimney leaks is a significant task when you are preparing your house before winter. Water can penetrate into the chimney through various areas, including flashing, cracked masonry, deteriorated mortar, and defective chimney caps.

On the interior side of your house, you should check for:

  • Ceiling stains: Brown or yellow stains around the chimney.
  • Damp attic materials: The wet insulation or damp wood near the chimney.
  • Peeling paint: Due to moisture, finishes may bubble or discolor.
  • Musty odors: The persistent odor around the chimney may indicate the moisture inside the house.
  • Damaged drywall: Repetitive moisture exposure may cause softening or deterioration.
  • The new stains appearing after the rain show that there is some exterior leak unresolved yet.

If you have the above-mentioned problems, you should look for the source of leaks.

Examine Chimney Masonry Before Winter

The brick and mortar may deteriorate after many years of exposure to moisture and temperature change. Cold weather intensifies the existing cracks since the moisture penetrates into the cracks and after freezing, it enlarges them. You should look for:

  • Cracks or missing bricks allowing moisture to penetrate into the deeper parts of the chimney.
  • The crumbling or missing mortar reducing the protection between masonry components.
  • Loose bricks showing the structural problems.
  • The white mineral deposits appearing due to moisture moving through the masonry.
  • Gaps or openings around the chimney requiring professional evaluation.

If masonry damage appears to be significant, you should contact a professional before winter.

Check the Chimney Cap and Crown

The chimney cap and crown prevent the upper part of your chimney from precipitation. A damaged cap or crown exposes vulnerable areas of the chimney.

You should look for:

  • Cracks expanding with the winter moisture.
  • Loose components that become vulnerable due to winter high winds.
  • Openings allowing the penetration of rain, snow, and debris into the chimney.
  • Deterioration of the concrete or masonry surfaces requiring repairs.
  • Buildup of the debris retaining moisture and preventing drainage.

You should solve these problems before winter to reduce moisture exposure.

Complete a Roof and Chimney Inspection Together

The Chimney and roof inspection provides a better look at your home’s exterior. The chimney and roof have a close connection, and therefore, the inspection of only the chimney may miss nearby roofing problems. Combined inspection can identify:

  • The damaged shingles around the chimney allowing water beneath the roof.
  • Deteriorated flashing allowing moisture into the roof.
  • Gaps around roof penetrations requiring sealing or repair.
  • The signs of water damage beneath the roof.
  • Drainage problems increasing moisture exposure.
  • Other roof problems that may intensify in winter.

A professional can decide whether the identified problems require only minor repair or more extensive roofing work.

Inspect Roofing Materials Around the Chimney

Homeowners should examine the roofing area around the chimney, not only the chimney itself. Roofing materials may deteriorate due to the age, weather exposure, poor installation, or previous storm damage. You should pay attention to:

  • The missing or displaced shingles around the chimney.
  • Cracked or curled shingles that are not able anymore to protect the roof.
  • The damaged underlayment that directs water towards the roof deck.
  • The loose flashing around the chimney base.
  • The discoloration of your roof indicating previous exposure to moisture.
  • The damaged roof decking that you can see from the accessible interior areas.

You should address these problems before winter to decrease water infiltration.

Clean Gutters and Improve Drainage

The gutters influence the movement of water around your roof. Blocked gutters may cause overflow or keep water around vulnerable areas of the roof. For these reasons, gutter maintenance is also part of your winter preparation. Homeowners should:

  • Remove the leaves and other debris blocking the free passage of the rainwater towards the downspouts.
  • Check the downspouts to ensure that they direct the water away from your foundation and surroundings.
  • Inspect the gutter connections for gaps, leaks, or loose fasteners.
  • Watch the standing water near the roofing areas showing the drainage problems.
  • Check the edges of your roof for staining, deterioration, or signs of prolonged moisture exposure.

Good drainage reduces unnecessary moisture around your roof and chimney.

Check Your Attic for Water Damage

The attic can give clues regarding your chimney problems. Although the exterior of the chimney looks fine, the water may already infiltrate into the house. You should check for:

  • The water stains around the roof penetrations and chimney areas.
  • Damp or unusually heavy insulation.
  • The discolored wood around the chimney and roof connection.
  • Musty odors indicating the moisture buildup.
  • The mold-like growth due to the persistent dampness.
  • The damaged roof decking requiring professional evaluation.

You should investigate the source of the moisture found in the attic.

Know When You Need Chimney Repair Services

Not all chimney problems require extensive repair but the delay with their solutions may turn the minor problems into major ones. You should consider professional Chimney Repair Services if you notice:

  • The cracks in bricks, mortar, or chimney crown.
  • Damaged or separated flashing in the roof connection.
  • The loose or deteriorated masonry creating the structural issues.
  • The repeated stains of water around the chimney.
  • The damaged chimney cap not protecting the opening anymore.
  • The moisture inside your attic or living space.

A professional will evaluate the problem and offer appropriate repair.

Why Hire a Roofing Contractor in New Jersey?

The trusted roofing contractor that New Jersey homeowners rely on can inspect the whole area around the chimney. This is important since chimney and roof problems often interconnect. For example, the water stain near the chimney may appear because of the damaged flashing and not because of masonry. The professional contractor can:

  • Inspect the roof and chimney connection for the visible damage.
  • Evaluate the flashing and other roof penetrations for the leaks.
  • Check the nearby roofing materials for deterioration or storm damage.
  • Identify the water entry points that homeowners may not notice.
  • Recommend repairs depending on the roof condition.
  • Decide if additional roof work is required before winter.

For New Jersey homeowners, the professional evaluation gives more confidence before severe winter conditions.

When Should You Schedule a Pre-Winter Inspection?

You do not need to wait until the first snowstorm for inspecting your roof and chimney. Ideally, you should organize an inspection in advance to be able to fix all necessary problems before the lowering of temperatures. You should consider an inspection if:

  • Your roof or chimney is old and was not inspected recently.
  • There are water stains or moisture around your chimney.
  • Your region has experienced recently the severe weather conditions.
  • You see the cracks in the masonry or damaged flashing.
  • Your roof has missing or damaged shingles.
  • You prepare the old house for its first winter.

The early action gives contractors more time to identify problems and perform repairs.
