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.

What to Know About Ice Dams

This winter has been fairly mild but the season is still in full swing and it won’t be long until we get another storm to remind us that we live in New England. Before that happens, I always like to talk about the dangers of ice dams and the reason why so many homes in our area get damaged by them. 

An ice dam is a solid mass that forms when heavy snow blankets the roof, creating an extra layer of unwanted insulation. As warm air rises from your house and up through your attic, it causes the snow to melt and the water to slide down into the gutters. This would typically be just fine, but because so many homes in our area aren’t properly insulated, the melting ice will often make contact with the cold eaves of the roof and freeze again instead of draining off through the gutters. This forms a large ice mass at the gutter line, which will grow if not taken care of.

Solid ice is heavy and can easily pull gutters loose. The dam can even get strong enough to lift up your roof shingles, creating gaps that let the water through and into the attic. This is when people start to see leaks in their ceilings and walls. 

The only way to prevent ice dams from forming is to have your home properly insulated and ventilated. More than 75% of homes in our area are under-insulated which causes the heat from your home to shoot right through the roof. Because insulation and ventilation weren’t regulated when most of the homes were built in this area, a lot of us have houses that are better suited for Florida winters than our cold Connecticut climate. 

Having appropriate insulation and ventilation will not only keep your home free from ice dams but will also keep you much more comfortable in both the winter and the summer. You’ll feel the difference immediately, and you’ll see the benefit in your energy bills too. A house that can breathe and can properly regulate its own temperature will also be less like to accumulate mold and mildew which is not only damaging to your house but also to your health. It’s a simple solution to keep your family, your home, and your wallet healthy.

Consider a Gutter Upgrade To Reduce Spring Cleaning

While most people think about gutter cleaning in the autumn, the falling of spring blossoms can cause serious clogging that creates overflows and inadequate rainwater drainage. 

Gutters have come a long way in the past few years. Back when many of the homes in this area were built, open gutters were used to collect rain off the roof and deposit it onto the ground through a system of downspouts. Open gutters, however, allow not only water but leaves, whirlybirds, blossoms, and sticks to also fall into the gutter, blocking them and eventually causing overflow without regular removal.

Gutter cleaning keeps me busy, mainly because it’s a dirty job that can also be dangerous if you’re not used to working on a ladder. Luckily, over the past few years, gutter manufacturers have smartened up, creating shields to install over your current gutters, as well as closed gutter systems that can replace your current setup.

Gutter guards come in a variety of materials and sizes, but they are all designed to maximize water flow while keeping tree debris out of the channel. The least expensive option is steel mesh screens which slide in and sit above the gutter lip itself. The arch design helps to ensure that debris can’t get stuck in the back of the gutter and they generally come with a five-year warranty against rusting or corrosion.

A step up from mesh screens is a heavy-duty aluminum option that can be fitted from the front and back, avoiding the need to remove roof shingles for installation. These products come with a ripple design to prevent leaves from drying on the surface and they are generally backed by a 20-year warranty so you don’t have to worry about replacing them often. I like these because the design strengthens the gutter which comes in very handy during major snowstorms when many homes in the area suffer from heavy and dangerous ice dams.

Finally, there is Leaf Relief, a heavy aluminum gutter shield that can drain nearly 30 inches of rainfall in one hour, which is 15 inches more than the highest rainfall ever recorded (for inquiring minds, that’s 12 inches in one hour in Holt, Missouri). For homeowners who want no maintenance, this is the gutter product for you. The 25-year no-clog, no-overflow warranty gives it the same lifespan as a new roof and the inset design makes it invisible from the road. Best of all, dry debris blows away with only a six-mile-per-hour breeze.

No matter what type of gutter guard you choose, you want to make sure that it’s the best product for your home. While any gutter guard will reduce debris getting into your gutter, the right guard will depend on the trees in the area, how much rainfall you get, the position of your house, and the size and age of your current gutters. Once those factors are taken into consideration and the appropriate product is chosen, you can say goodbye to messy cleaning and enjoy less maintenance at your home.
