Roof leaks are a homeowner’s nightmare, leading to potential damage, mold growth, and costly repairs.

While many people associate roof leaks with damaged shingles or flashing, one often overlooked culprit is the chimney. Chimneys can be a source of significant water damage if not properly maintained. But how do you know whether your leak is coming from your roof or your chimney?

How Your Chimney Can Cause a Roof Leak:

Cracked or deteriorated chimney crown: The chimney crown is the concrete or cement layer at the top of the chimney. Over time, exposure to harsh weather conditions can cause it to crack or deteriorate, allowing water to seep into the masonry and eventually into the roof.
Damaged or missing chimney flashing: Flashing is the metal strip that seals the intersection between the chimney and the roof. If the flashing becomes damaged, improperly installed, or starts to deteriorate, it can create a pathway for water to enter the roof system.
Crumbling mortar joints: The mortar that holds the bricks or stones of the chimney together can deteriorate over time due to weathering. As the mortar crumbles, gaps and openings can form, permitting water infiltration into the roof.

How to Detect a Chimney-Related Roof Leak:

Internal signs: Look for water stains, peeling paint, or discoloration on ceilings or walls near the chimney. These are often indicators of a leak. Mold growth or musty odors may also be present.
Exterior signs: Inspect the chimney for cracks, crumbling masonry, or missing flashing. Pay attention to any signs of water pooling on the roof or around the chimney after a heavy rainfall.
Attic inspection: Check your attic for signs of water damage, such as damp insulation, water stains, or rotting wood near the chimney.

Taking Steps to Repair the Damage:

Consult a professional: If you suspect your chimney is causing a roof leak, it is crucial to contact a qualified roofing professional and/or chimney specialist. Depending on the damage you may need both specialists to come in and do repairs – especially if a chimney leak has caused damage to nearby areas of your roof.
Chimney crown repair: If the chimney crown is cracked or deteriorated, it should be repaired or replaced. A chimney professional can apply a waterproof sealant or construct a new crown to prevent water penetration.
Flashing replacement: Damaged or missing flashing should be replaced with new, properly installed flashing. This will ensure a secure seal between the chimney and the roof. A qualified roofing contractor can do this repair and in some cases a chimney repair company can as well.
Mortar joint repair: If the mortar joints are deteriorating, a process called tuckpointing can be performed. This involves removing the damaged mortar and replacing it with new mortar to restore the chimney’s integrity. This should only be done by an experienced chimney and masonry expert.
Regular maintenance: To prevent future leaks, schedule regular chimney inspections and maintenance. Keep the chimney free of debris, ensure proper ventilation, and consider applying a waterproofing sealant to protect against moisture.

While chimneys provide warmth and charm to our homes, they can also become a pesky source of roof leaks if neglected. Just like other functional and structural aspects of your home, pay attention to your chimney and visually inspect it regularly. If you think it may be causing any leaks or issues, contact a professional as soon as possible before further damage is done. By addressing chimney-related issues promptly, you can protect your home and preserve its structural integrity for years to come.

For some things in life, it’s very easy to know when it’s time to call in a professional. If your car breaks down on the highway, it’s time for a mechanic. If you break your leg, it’s time for a doctor. But there are some things that are a little less obvious. For instance, knowing exactly when to call in someone to service and inspect your roof can be tricky for some homeowners. A lot of your roof may not be visible to you, and from the ground it can be difficult to spot some of the tell-tale signs of decay or damage. But there are a few good ways to tell if it’s time to call in a roofing professional, so here are some signs to look out for.

Soaring Energy Bills
Your energy bill may be soaring lately because of rate increases, but pay attention to the actual kilowatt hours you’re using each month. If that number has started to rise over time and you haven’t made any changes or added any new electrical elements to your home, that can be a sign of a roof that needs service. That’s because your roof is one of the main temperature control elements of your house. A leaky roof lets water in but it also lets warm or cold air out. Don’t pay money to air condition the outside, call a roofing company instead and see if any repairs are needed that will help make your energy bill (somewhat) more reasonable.

Sagging
A sagging roofline – usually a gentle slope down toward the middle of a roofline, or drooping at the edge of an eave – is a sign that there are problems with the underlying structure. This could mean that the rafters, roof decking or both have started to deteriorate. This can happen due to age, but it can also happen if moisture is coming in through the roof, causing the wood beneath to rot or invite termites. In any of those cases, a professional roofing company and potentially a general contractor and pest company may be needed to address this issue. Left unchecked, a sagging roof can cause massive and extremely expensive damage to the core structure of your home.

Dark Spots
Leaks don’t always present themselves as a steady stream of water or even a drip directly from the ceiling. In slow leak cases, a dark spot on in the interior will appear and start to grow in the area where the water is penetrating the roof. This is often in the corner of rooms that are along the exterior of a home. The dark spots may appear on the ceilings, but they also can appear along and down walls, especially if water is entering the house along the roofline. As soon as you see a dark spot start to appear, call a roofing company. The longer you allow those spots to grow and exist, the more likely it is that mold, mildew, and other types of water damage will occur in areas beyond your home’s roof. Drywall, trim, window casings and even flooring may need to be replaced if leaks are not addressed quickly.

Debris
If you’re finding bits of asphalt shingles in your yard, especially after a weather event, this may be a sign that your roof needs to be replaced. While asphalt shingles are very durable, they do have a life expectancy of 20-30 years. This means that even homes built after the year 2000 may be due for a new roof. Another sign of shingle deterioration is asphalt grit in your gutters. Small, sandy bits of a shingle’s asphalt will start to slough off when they’ve reached the end of their lifespan, and very often this material will make its way into your gutters and even down the downspout. Again, this is especially noticeable after a weather event with heavy rain.

The Obvious
Of course, there are some obvious signs that it’s time for a roofing professional’s opinion. Missing shingles, clear water leaks, or a roof that’s older than 30 years most certainly requires a service call to your local roofing company.
