How to Spot Trouble with Your Chimney Before Fireplace Season

As the days get shorter and the air gets cooler, many homeowners look forward to that first cozy fire of the season. But before you strike a match, it’s important to make sure your chimney is in good working order. A damaged or blocked chimney doesn’t just reduce efficiency - it can create serious safety hazards, including chimney fires and carbon monoxide buildup. The good news? A little preventative maintenance now can save you from expensive repairs and dangerous situations later.

Here’s what to look for when checking your chimney this fall.

Cracks and Gaps in the Masonry

Start with a visual inspection. If you see crumbling mortar, missing bricks, or hairline cracks, that’s a sign your chimney is weakening. Water can seep into these gaps, freeze in the winter, and make the damage worse. Over time, this can compromise the entire structure. Small cracks can often be sealed, but larger problems usually require professional repair.

A Damaged Chimney Cap or Crown

Your chimney cap is the unsung hero of the fireplace system. It keeps out rain, snow, animals, and debris. Without it, your chimney can quickly become clogged or water-damaged. Similarly, the chimney crown - the cement slab at the very top - acts as a shield. If you notice rust on the cap or chips in the crown, it’s time to repair or replace before moisture finds its way inside.

Creosote Buildup

Even if the outside looks fine, the inside of your chimney can be another story. Burning wood produces a tar-like substance called creosote, which clings to the interior walls. Creosote is highly flammable, and too much of it can spark a chimney fire. If you notice a strong, smoky odor, or if you can see black, shiny buildup inside, schedule a professional cleaning before you use the fireplace again.

Signs of Water Damage

Look around the base of your chimney and inside your attic for water stains or dampness. Discoloration on ceilings and walls near the chimney can be a red flag. Water entering through cracks or missing flashing (the metal seal where the chimney meets the roof) can cause mold, rot, and costly structural issues.

While You’re Up There - Check Your Roof

Inspecting your chimney is also a great opportunity to take a quick look at your roof. Loose, curling, or missing shingles can lead to leaks that damage not only your chimney but your entire home. Shingle problems are easiest to fix when they’re caught early, so don’t wait until you see water spots inside your house to take action.

When to Call a Pro

Some issues, like trimming back tree branches or replacing a simple cap, may be safe for homeowners to tackle. But climbing on a roof always comes with risks, and chimney repairs often require professional tools and expertise. If you’re unsure about the condition of your chimney or roof, schedule an inspection with a qualified contractor. It’s a small investment that can prevent big problems down the line.

A healthy chimney doesn’t just make your fireplace more efficient; it keeps your family safe, too. Take a little time this season to inspect for cracks, damaged caps, creosote buildup, and signs of water leaks. And while you’re up there, give your roof a once-over, too. A careful check now means peace of mind when you’re enjoying those winter nights by the fire.

Put a Roof Check on Your Fall Maintenance List

When it comes to protecting your home, your roof is the unsung hero. It shields you from rain, wind, snow, and sun every single day. Yet most homeowners don’t think twice about it until a problem pops up. By then, it’s usually more than just a minor inconvenience. That’s why fall is the perfect time to give your roof some attention. Taking a little time now can save you a lot of stress and money once winter sets in.

Take a Quick Look

Start simple. Stand back in your yard and scan your roof from the ground. Do the shingles look flat and uniform? Or do you see sagging areas, dark streaks, or patches that just don’t look right? Those could be early warning signs of bigger problems.

Don’t forget the inside of your home either. Water stains on the ceiling, peeling paint, or small cracks in your walls can all signal that moisture is making its way in. Even if you don’t see active dripping, these issues usually start small and then spread. Catching them early is the key.

Remember the Roof’s Birthday

Age is one of the biggest factors in how your roof performs. Most roofs last about 20 years, but that number isn’t set in stone. The quality of the installation, insulation, and ventilation all make a difference. A roof that’s well-installed and properly ventilated can easily last a few extra years, while a poorly maintained one can wear out much sooner.

If your roof is pushing the two-decade mark - or if you’re not sure how old it is - it’s time to start planning ahead. This is especially important if you’ve recently bought your home. Knowing when your roof was last replaced can help you budget and avoid surprises down the road.

Check Those Shingles

Shingles are your roof’s first line of defense, and they’re also one of the easiest things to inspect. Look for shingles that are curling at the edges, splitting down the middle, or missing altogether. These issues often happen as roofs age and are exposed to the elements year after year.

While you’re at it, take a peek at your gutters and downspouts. If you notice piles of shingle granules collecting there, it’s a sign that the protective coating on your shingles is wearing away. Once that happens, your roof is much more vulnerable to leaks.

Don’t Brush Off Moss or Mold

It’s not unusual to see a little moss or dark staining on a roof, but don’t ignore it. Moss and mold thrive in damp, shaded areas, and they can signal that moisture is getting trapped under your shingles. Left unchecked, that moisture can lead to rotting plywood and costly structural damage.

Sometimes, the fix is as simple as cleaning the roof and improving ventilation. Other times, it may require replacing damaged areas. If you’re not sure which it is, calling in a professional is the safest route.

Look Inside, Too

Your ceilings and walls can often tell you what your roof can’t. Yellowish-brown stains, bubbling paint, or cracked drywall are all signs of water damage. Even if the issue looks small, it’s best not to wait. Roof leaks don’t heal themselves - they only get worse. Acting quickly can prevent a small drip from becoming a major repair job.

Call in the Pros

If you’re not comfortable judging the condition of your roof - or just want peace of mind - bring in an expert. Many roofing companies, ours included, offer free inspections. A roofer can tell you how much life your roof has left, point out any problem areas, and recommend the best next steps.

One of the most common reasons roofs fail before their time is poor ventilation and insulation. These issues can cause shingles to age faster, trap moisture, and even lead to rot. A good roofer won’t just look at the surface - they’ll check what’s going on underneath, too.

A little preventative maintenance this fall can make all the difference. Your roof protects everything beneath it. Giving it a checkup now means fewer surprises, fewer headaches, and fewer bills later on.

5 Late‑Summer Home Projects to Tackle

As summer winds down here in Connecticut, now is a golden opportunity to tackle home improvement projects with maximum return. Late summer offers warm, dry days that are perfect for outdoor work before the wet chill of fall sets in. Here are five smart projects every homeowner should consider while there’s still daylight (and deck furniture to enjoy).

1. Exterior Painting or Staining

August and early September give you cooler, less humid weather which are ideal conditions for paint and stain to dry evenly without peeling or blistering. Whether it’s freshening up siding, restoring your deck, or repainting trim, late summer ensures the new finish cures properly for a long-lasting result.

2. Roof Inspection & Minor Repairs

Summer storms can loosen flashing and shingles, and if left unchecked, those small issues become leaks once the snow flies. A roof check now helps you avoid water damage and insulation headaches. Plus, contractors in Connecticut can often still fit this work into their schedules before fall gets busy.

3. Gutter Cleaning & Guard Installation

Leaves haven’t started falling yet, so now’s the best time to clean out your gutters and downspouts. While you’re at it, consider adding gutter guards. This prepares your home for leaf season and keeps you off the ladder in cold weather. It’s an investment you won’t regret. 

4. Window Sealing or Replacement

Drafty windows? Now’s the time to replace or seal them before the heating season hits. Caulking and weatherstripping stop cold air in its tracks, while double‑pane, energy-efficient replacements reduce your heating bills. Connecticut homeowners can tap into rebate programs for these upgrades. Check out Energize CT for information.

5. Driveway Sealing or Repairs

Sealcoating your asphalt driveway protects it from salt, freeze-thaw cycles, and ice damage, just what Connecticut winters bring. Asphalt requires daytime temps above 50 °F to cure; late summer givesplenty of time before cooler weather sets in.

Late summer may feel like the calm before the leaf blowers, but it’s also prime time for smart homeowners to take care of the jobs that will protect and preserve their homes into the colder months. A little time and effort now can go a long way toward keeping your home dry, warm, and efficient all season long.
