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's That Smell in Your Basement?

Most people think that a musty-smelling basement is normal. After all, isn’t that what you would expect from a part of the house that’s underground? The truth is that, while common, that damp odor that’s become expected is actually a sign of something more sinister than smell. 

First, let’s address what it is we’re smelling. Since basements are damper than any other part of the house, they are susceptible to higher humidity. Where there is high humidity, there is also a high chance for mold and mildew to spore. Why is this a problem? In addition to being bad for your home’s health, it’s terrible for yours too. Mold and mildew can bring on asthma and allergies and can make anyone with a respiratory problem feel a lot worse. 

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 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.

Once you have rid your basement of extra moisture, 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 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 seem to have difficulty breathing at home, it might be worth a call to your local pro for an air quality inspection. The symptoms of a mold allergy are not dissimilar to a common cold or even COVID, so a simple reading of your in-home humidity might be a smart step once other things are ruled out.

Spring Rain Means Basement Leaks

Winter and spring are the two most common times for house leaks. During the colder months, it’s generally the roof that’s a worry, but as spring starts to edge closer, the basement takes centerstage. 

As the temperature warms, residual snow melts, the rain becomes more frequent, and the ground gets saturated with water. This water can find its way into your basement through non-structural cracks in poured concrete walls or deteriorated joints in masonry walls. Poorly fitted or old basement windows can also let water in, as well as utility openings. 

The best line of defense against a wet basement is to make sure that the water is directed away from the foundation. Inspect your gutters and downspouts to see if they are flushing out the way they should be and also check to see that the ground right around the house is higher than the rest of the yard. Having the yard grade at its highest around the perimeter of the foundation will ensure water drains away from the house instead of into it.  

If you think your home is susceptible to leaks, you can also use a waterproofing membrane or coating to seal the foundation or basement area. However, if you have regular leaking problems, you may need to have a drainage or sump pump system installed by a professional. 

Even if you don’t have a leak problem, the basement can get pretty damp in the springtime which creates the perfect environment for nasty mold and mildew. To get rid of the excess water, I always like to run a dehumidifier in the basement as the weather warms up. 

A dehumidifier works by pulling the moisture out of the air and storing the excess water in a holding tank. Many people keep dehumidifiers in their basement all year long to control the dampness that can often be felt in underground areas, but I find it especially useful this time of year. 

You can find out if your basement is holding a lot of moisture by purchasing a simple five-dollar humidity gauge from the local hardware store. Ideally, you want the humidity to be under 50%. If it’s higher, a dehumidifier might be a good solution. Generally, a unit will come in 25, 30 and 40-pint models, and on average a 25-pint unit will be sufficient to control the moisture in a 1,000 square foot area.

One last word of advice - if you have a dehumidifier or plan on getting one, please be sure to empty it regularly and keep the filter clean. A simple wipe down with a damp cloth and spray bottle will do the trick to keep you breathing freely and ensure a longer life for the appliance.
