Tackling Mold on Your Roof

Mold is a type of fungi that thrives in damp and humid conditions, making your roof a potential spot for growth. While roof mold might not be as noticeable as the mold you see inside your home, it can lead to some serious issues if ignored. Here are a few things to keep in mind about the risks associated with mold on your roof:

Structural Integrity: Mold can weaken your roof’s structure. It can damage shingles, deteriorate wood, and affect the overall stability of your roofing system.

Health Concerns: Mold spores can become airborne and make their way into your home, potentially causing respiratory problems, allergies, and skin irritations.

Energy Efficiency: Mold can compromise your insulation, leading to higher energy bills and a less comfortable indoor environment.

Curb Appeal: A moldy roof isn’t just a concern for your home’s health; it can also impact its appearance and market value.

To keep your home and family safe from the risks of mold, it’s important to take proactive steps. Here are some friendly tips for prevention and remediation:

1. Schedule Regular Roof Inspections: Aim for annual inspections to catch mold early. Professionals can spot potential issues before they become serious.

2. Ensure Proper Ventilation: Good airflow in your attic and roof helps keep moisture levels in check, reducing the risk of mold. Consider adding roof vents or attic fans if needed.

3. Clean Your Gutters and Downspouts: Clogged gutters can lead to water pooling on your roof. Regular cleaning can help prevent this and reduce mold growth.

4. Repair Any Leaks Promptly: Address signs of water infiltration as soon as you notice them. A leaking roof is a prime spot for mold to thrive.

5. Act Quickly on Mold Removal: If you discover mold, it’s important to take action. Hiring professionals experienced in mold removal is the safest way to ensure thorough and effective treatment.

6. Install Zinc or Copper Strips: Consider placing these metal strips at the top of your roof. Rainwater reacts with them to release ions that can help prevent mold and algae growth.

7. Trim Overhanging Trees: Keeping tree branches away from your roof allows for better sunlight and airflow, which can deter mold growth.

8. Choose Mold-Resistant Roofing Materials: When it’s time for a roof replacement, consider materials designed to resist mold growth.

Mold on your roof is a concern that deserves attention. By taking preventive measures and addressing issues promptly, you can protect your home and your loved ones. Regular inspections, proper ventilation, and maintenance are key to keeping your roof healthy. If you find mold, don’t hesitate to seek professional help to ensure your roof stays mold-free. A well-maintained roof not only safeguards your home but also enhances its beauty and value.

A Fall Maintenance To Do List

As the days get shorter and outdoor projects become harder to tackle, now’s the perfect time to take care of a few key tasks before the colder weather sets in. Here are my top five tips to prepare your home for fall and winter.

1. Clear Those Gutters Falling leaves are just around the corner, and they’ll quickly clog your gutters and downspouts. If you've been thinking about installing gutter guards, now’s the time! These will prevent debris buildup and spare you the hassle of frequent clean-outs. Clean, functional gutters are essential to channel water away from your home and avoid potential damage.

2. Check Your Doors Stiff, hard-to-open doors are a sign that cooler temperatures are already having an effect. As the weather shifts and wood contracts, gaps can form, allowing cold air to seep inside. Make sure your door sweep is in top shape, and consider adding weather stripping to seal any cracks between the door and its frame.

3. Assess Your Insulation Many homes I visit are under-insulated, which creates discomfort in both winter and summer. Adequate insulation helps maintain a steady temperature throughout the house. If your second floor is consistently warmer than the first, it’s a good indication that your home could benefit from more insulation.

4. Inspect Your Roof Now is an ideal time to check your roof for any damaged shingles or issues around the chimney flashing. Snow lingers on roofs far longer than rain, making it easier for leaks to develop during the winter. Addressing small roof problems now can prevent larger, more expensive repairs later.

5. Evaluate Your Windows Using a thermal camera, I often find homes losing a lot of heat through old wood sash or aluminum windows. Replacing them with energy-efficient vinyl windows can make a noticeable difference. And the added bonus? Many vinyl windows come with tilt-in sashes for effortless cleaning, which we love at my house.

6. Get Your Hot Water Heater Tuned It’s not an outside project but if your hot water heater isn’t working when you need it, it’s going to make life very uncomfortable. Make an appointment now to have your systems flushed and inspected before the season gets too busy, or DIY it if you’re comfortable doing the work. Either way, don’t wait until it’s too late.

Owning a home means regular upkeep, but it’s an investment that pays off in comfort and energy savings. By taking a few simple steps now, you can enjoy a cozier home this winter—and keep those utility bills in check.

Attic Ventilation is Key for the Home

I recently did work for a homeowner who got the shock of her life when we removed her old roof and found sheet after sheet of black, rotten plywood. The homeowner couldn’t believe it and asked me how the plywood could be so damaged if she had never had a roof leak. 

The answer is quite simple and a lot more common than you think. In our area of Connecticut, nearly all attics don’t have enough insulation and aren’t ventilated properly. I meet people who need a new roof and want me to just lay an extra layer of shingles over top of what they already have to save money. What they don’t realize is how much deterioration exists that they simply can’t see.

With a roof, airflow is absolutely crucial. Attic ventilation allows your home to “breathe” by taking in air from the outside and letting out air from the inside. Too many homes that I work in aren’t properly ventilated, in fact, most have their bathroom and even dryer vents going into the attic instead of outside. In order to have proper ventilation, your home needs a system that includes intake ventilation through the soffit or a new product called SmartVent which is installed on top of the roof near the gutter edge. Louver vents were typically used at an exhaust vent in the 1950’s and 1960’s but now ridge vents are more common. If your house has both louver vents and ridge vents, the louver vents should remain closed, otherwise, the louver will act as an intake vent and will only cool the top third of the attic. 

In the colder months, it’s not uncommon for me to see frost on attic plywood because of subpar insulation. Insulation and ventilation work hand in hand - the ventilation controls the airflow and the insulation controls the temperature. You’re probably familiar with insulation - it’s a cotton-looking fiberglass material that often comes in pink or yellow rolls. It can also be loose-filled into tough to reach areas with a blowing machine. Remodeling professionals use insulation between walls, in attics and in basements to retain heat in the house in the winter and keep it cooler in the summer. However, without proper ventilation, the insulation is just as susceptible to moisture and deterioration as the plywood.

My customer didn’t venture into her attic, so she never noticed the problem. What she thought was a simple roof replacement ended up being a bigger job simply because after years of decay, the plywood she had was no longer strong enough to properly support the new roof. Ignoring the problem would have voided the new roof’s 30-year warranty.

The lesson for this week? If you’re going to reroof your home, make sure that the plywood is healthy and that your contractor has given you a thorough plan to ensure that your home is properly insulated and ventilated. It might cost a bit more today, but it will regulate the heat and cooling in your home for years to come, saving you on energy costs and giving you more comfort as well as peace of mind for the health of your house.
