Tackling Humidity Hazards at Home

With a solid mix of heat, humidity, and rain so far this summer season, now is the perfect time to talk about what high moisture can do to your home. 

Let’s start with a bit of background on mold, which is the biggest threat to homes that hold a lot of humidity. Mold is made up of thousands of microscopic spores that travel through the air until they land on a surface. They love to live in places that hold water, which is why you often see mold growing on trees, roofs, and other places that stay warm and damp. Indoor mold generally develops after being carried in from the outdoors or because of a leak that hasn’t been remedied. Homes that tend to hold a lot of humidity are more susceptible to mold infestation, something that no homeowner wants to deal with. 

Many people can get sick from mold and mildew, especially children and the elderly. It grows and spreads incredibly quickly and cannot be contained without removing its food source, which is water. Once it settles inside a home, mold can cause illness, asthma, and a host of other respiratory issues that can affect a person’s health for life.

So how can you get rid of mold in your living space, or prevent it from making a home in yours? Here are my top tips.

1. Run a dehumidifier in your basement constantly. I have an air-tight finished basement and I still run a dehumidifier 24/7. The goal here is to keep your air humidity at or below 50%. When it’s raining or super humid, don’t be surprised if you have to dump the water collection bucket twice a day. 

2. Always use the extractor fan while showering or cooking. With so much water in the air from the weather, the last thing you want to do is add more moisture inside your home. Be sure that your fans vent outside, not in the attic. Otherwise, you’re just redirecting the moisture to another part of the house. 

3. An air conditioner is not a dehumidifier. Yes it will remove some humidity but an air conditioner’s main function is to cool the air, rather than remove the water. If you find yourself running your A/C unit to control your humidity, you’re going to end up with an expensive energy bill and not too much to show for it.

4. Store unused clothing and linens in airtight plastic. People often put winter clothes and bedding up in the attic, which can be a breeding ground for mold if the area is not ventilated properly. Keeping the attic vented is key, good airflow can slow or even prevent mold growth.

5. Check the drainage around your home. Gutters should be clean and in working order and your landscaping should slope away from the foundation so you don’t have standing water at the base of your house. Make sure your downspouts extend at least four feet out and away from that foundation.

In short, a house with high humidity is nothing to ignore. If you suspect that your home might be susceptible to mold, it’s worth purchasing an inexpensive humidity gauge to find out. Remember, a mold problem can be a serious health risk to your family if not dealt with properly.

What’s Growing In Your Attic

This past week’s brutal temperatures had plenty of people thinking about the heat in their homes. While high energy bills, drafty windows, and cold floors are the obvious issues, what most homeowners don’t see is what’s causing the biggest problems in their homes. 

Most of the houses in our area are underinsulated and not properly ventilated. We all know from high school science class that heat rises, right? In a house, that means a good amount of heat makes its way up to the attic where it’s usually pretty cold. When warm and cold air collide, it creates moisture or condensation, which is the last thing you want up there. As an attic collects moisture, it adheres itself to any surface, which in an attic’s case is usually wood. That moisture becomes an ideal home for mold spores, which eat away at the plywood, causing it to rot. 

An attic that has enough insulation and ventilation allows air to flow through and temperature to regulate, which creates a healthy atmosphere and keeps a home warmer in the winter and cooler in the summer. A home without proper insulation and ventilation is susceptible to mold infiltration which will create rot, roof leaks, and can even become a potential health hazard in your home, especially for folks with asthma or allergies. 

So how do you know if your home has enough insulation and ventilation? A roofing contractor will be able to help you identify exactly what you need, but a good place to start is insulation. Insulation is measured by its R-Value, which is the level at which heat can penetrate it. According to EnergizeCT, the recommended R-Value for a home here in Connecticut is R38 to R60, which is roughly 12 inches thick at the low end of that range. If you can access your attic, you’ll be able to get an idea of your insulation situation. More than 75% of homes I visit don’t come close to an R-Value of 38, in fact, homes built before 1940 didn’t require insulation at all. Those built in the decades after usually have enough to be suitable for winter in Florida. 

A warm, energy-efficient, and healthy home always starts at the roof. Ensuring your home has enough insulation and ventilation is the best way to prevent bigger problems such as leaks from happening in the future. Plus, getting your home insulated and ventilated properly offers both tax credits and will immediately make a big difference in those energy bills. Don’t forget your family’s health as well. Illness from long-term exposure to mold is not something anyone wants to deal with.

Is It Time For A New Roof?

When was the last time you checked out your roof? If it has been a while, now is the time to do it. Most roof problems are caused by snow, wind, rain, and ice, making spring the perfect season to assess your home for damage. 

When you look at your roof, what do you see? Are the shingles intact? Is any part sagging or discolored? Are there dark spots on the outside or ceiling cracks and yellowing on the inside? These can all be signs of a deteriorating roof. But how long is a roof actually supposed to last, and is a new roof worth the investment? Here are some things to think about when it comes to roof replacement.

1. How old is your roof? Roofs generally last about 20 years, and the reason I say generally is that the life of the roof depends on how it was installed and if it has proper insulation and ventilation. If a roof is done correctly, it can often last longer than 20 years. If you don’t know, it’s worth finding out, especially if you recently purchased your house or are thinking about purchasing one.

2. Are your shingles curling, splitting, or falling off? This could be due to age and general wear and tear. If this is happening, your roof will be much more susceptible to leaks, which can cause major problems both inside and out. Take a look at where your downspouts deposit onto the ground. If there are lots of granules, that’s a sign of shingle deterioration.

3. Do you see moss or mold growing on your roof? This is a problem that could be fixed with a simple roof cleaning, or it could be a sign that you have rotting wood and damaging moisture trapped under the shingles. A simple inspection will tell you if it’s a quick cosmetic fix or something more complex that needs to be repaired.

4. Are there yellowish-brown stains or cracking on the ceiling inside the house? This is likely water damage coming from the attic. This is a problem you don’t want to ignore as water is likely already entering the home and the problem won’t fix itself. 

Many remodelers will do a roof inspection for free, so if you’re unsure about how your roof is holding up, consult with an expert. I always tell the homeowners how long I think their roof will last based on its current condition and the external environment. The number one reason roofs don’t make it through their warranty is because of poor ventilation and insulation, which lead to premature roof aging and rot. If you’re dealing with a good roofer, they will explain all the options available to you so don’t be afraid to ask questions.
