Is Fall Mold Creeping Onto Your Roof

As the crisp autumn air settles in and the leaves start to fall, most homeowners are focused on pumpkin decor and raking their yards. But there’s something sneaky that may be settling in overhead: roof mold. Yes, fall is prime time for mold to make itself at home on your shingles, and ignoring it could lead to bigger (and more expensive) problems down the road.

Let’s break down what roof mold is, why it thrives in the fall, and what you can do to kick it to the curb before it spreads.

Why Fall Is Mold’s Favorite Season

Mold is a fungus that loves moisture, shade, and organic debris - all of which come together perfectly during autumn in New England. Here’s why:

• Falling Leaves: Leaves that land on your roof can trap moisture and block sunlight, creating damp, shaded pockets where mold thrives.

• Cooler Temperatures: As temperatures drop, homeowners may not notice excess moisture buildup because it’s not evaporating as quickly.

• Shorter Days: Less sunlight means less natural drying power for your roof.

• Clogged Gutters: Leaf-filled gutters lead to poor drainage and water pooling on the roof. Mold eats this up, literally.

What Mold Does to Your Roof (It’s Not Just Ugly)

Roof mold might seem like just a cosmetic issue, until it isn’t. Here’s what can happen if mold takes hold:

• Shingle Damage: Mold can deteriorate asphalt shingles and shorten your roof’s lifespan. It eats away at the granules that protect your roof from UV rays and weather damage.

• Wood Rot: If moisture seeps beneath the shingles, it can lead to rotting of the underlying wood structures, threatening your roof’s structural integrity.

• Insulation Issues: Mold creeping into your attic or insulation can ruin energy efficiency, sending your heating bills through the roof - pun intended.

• Health Concerns: Mold spores can make their way into your home’s air, potentially triggering allergies, asthma, or other respiratory issues for your family.

How to Stop Fall Mold Before It Starts

The good news? Roof mold isn’t inevitable. With a little proactive maintenance, you can keep your roof mold-free all season long. Here’s how:

1. Clean Your Roof (and Gutters)
   Leaves, twigs, and debris are mold’s favorite housewarming gifts. Clear your roof and gutters regularly, especially after a big wind or rainstorm.

2. Check Your Attic Ventilation
   Poor airflow in the attic can trap moisture and encourage mold growth from the inside out. Make sure vents are clear and consider installing an attic fan if airflow is limited.

3. Trim Back Overhanging Branches
   Shade is great for picnics, not for roofs. Cutting back branches allows more sunlight to hit your roof and dry up any lingering moisture.

4. Inspect for Leaks and Damaged Shingles

   Take a walk around your home and look for signs of water damage, cracked shingles, or dark streaks. If you spot anything suspicious, call in a pro.

5. Consider Copper or Zinc Strips
   These metal strips, installed near the peak of your roof, naturally kill mold and algae as rainwater washes down over them. It’s a smart investment for long-term mold prevention.

6. Book a Professional Roof Inspection
   Fall is an ideal time to have a professional take a look. They can spot early signs of mold or damage you might miss from the ground.

When in Doubt, Call It Out

If you already see mold growing on your roof, don’t panic, but don’t ignore it either. DIY solutions may help with small patches, but for widespread or stubborn growth, it’s best to bring in the experts. Professional mold removal will ensure it’s safely and thoroughly taken care of, without damaging your roof in the process.

A clean, mold-free roof isn’t just about curb appeal. It’s about protecting your investment, your home’s structural integrity, and your family’s health. So this fall, while you’re sipping cider and enjoying the foliage, take a few minutes to look up. Your roof might be trying to tell you something.

Wind Damage Tips To Prepare Your Home for Future Storms

This week’s wild weather was not to be taken lightly. I’ve had calls from all over the area to fix roofs, repair gutters, and replace siding that was damaged. While high winds aren’t very common, they can cause major headaches for homeowners, especially those who have to go through the process of making an insurance claim. With that being said, here are my six tips for “weathering the storm” that inevitably comes with unanticipated damage to your home.

Check your policy now

Every insurance policy is unique and it’s really important to review your coverage annually to make sure you’re up to date with the inclusions and exclusions. Most homeowner's policies cover damage due to wind but other storm-related issues such as flooding are usually not part of the deal. The State of Connecticut Insurance Department has a basic homeowner’s storm damage FAQ on their website, but because all policies and insurers are different, it’s worth talking to your agent.

Be very careful

Damage can’t always be seen, so it’s important to exercise extreme caution. Inspect the power lines around your home as well as the trees. Even if nothing is down now, a broken limb could fall later, so it’s better to be diligent. Also, be sure to watch for leaks in the days and weeks after bad weather. High winds often rip off shingles, leaving roofs exposed to water. 

Make use of your camera

The most common types of storm-related damage are to roofs, windows, siding, and windows. As you inspect your home, take photos or everything and don’t move anything unless it's necessary. Video is also a great way to document any potential damage. The more evidence that you have, the better off you’ll be when you go to make an insurance claim. 

Call your insurance company

Once you’ve assessed any potential damage, you can get in touch with your insurance provider. Do this as soon as possible and be ready with all the documentation that you’ve collected. Your insurer will be able to assess the damage to your home and help you understand what's covered by your policy. They’ll also connect you to a claims agent if required.

Make repairs

After you’ve reported any damage, it’s time to clean up. Leaving exposed areas uncovered and not fixing leaks will create much bigger issues, so be sure to clear and patch any problem spots. Do not ever try to touch downed power lines or electrical equipment - report those to your electricity provider or even your town’s fire department. 

Hire a good, local contractor

Believe it or not, there are some hacks out there who chase storm damage, taking advantage of homeowners who need a fast fix. Don’t fall for these traps - look for someone local, reputable, who has a good track record, and is fully licensed and insured. The Better Business Bureau is a great place to get started.

A Musty Basement Isn't Just an Odor Issue

A lot of people think that the musty scent of a basement is par for the course. Isn’t having a space that’s underground going to smell no matter what? The answer is actually no. Sure, basements are prone to higher humidity which means that it’s easier for mold and mildew to spore since moisture enables them to thrive. So that basement smell is actually mold, which, in addition to having a funky odor, can also cause decay and damage to a home over time. For people who suffer from asthma and other respiratory issues, the problem can be even more serious. 

The ideal humidity level for most homes is 50% or lower, but in basements, humidity can often skyrocket to 80%, which is the perfect environment for mold and mildew to flourish. If your basement seems extra damp, I highly suggest investing in a dehumidifier that will work to draw the moisture out of the air. You’ll be shocked at how quickly the holding tank on an average-sized unit fills. You may have to dump it daily, but in doing so you’ll be removing moisture that allows mold to grow in the first place.

Next, it’s time to purify the air. Overly humid areas attract a lot of bacteria, which is what causes the smell in the first place. That bacteria can live in walls and spread into your fabrics, furniture, and storage. By killing the bacteria in the air, you will remove contaminants that not only stink, but can also cause or irritate allergies, asthma, and immune system disorders.

One of the best air dehumidification and purification units I’ve seen is by a company called Aerus.  They produce a system that uses NASA technology to remove pathogens, pollution, contaminants, and even pet dander from the air. Regardless of what brand you go with, be sure to look for a unit that has the EnergyStar seal, and make sure that you pay attention to the capacity of the air filtration as it pertains to your room size. If you have a big space with a lot of moisture, you might want to consider a unit that has a self-draining system to save your back and your patience.

Regardless of your plan of attack, the air quality in your home should be taken seriously. If your kids are coughing or have allergies and you find yourself having difficulty breathing at home, it might be worth a call to your local contractor for an air quality inspection. The symptoms of a mold allergy are not dissimilar to a common cold, so a simple reading of your in-home humidity might be a smart first step.
