Beware of Dangerous Ice Dams

We all know that snowfall, freezing rain, and sleet make for icy conditions on sidewalks and roads. But did you know that your roof is actually where hazardous winter weather can do the most harm? 

I’m talking about ice dams, a solid mass that forms when heavy snow blankets the roof, creating an extra layer of 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 normally 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 an ice blockage. 

If not taken care of, that ice can grow if the weather stays cold. The dam can even get strong enough to lift up your roof shingles, creating gaps that will let the water through and into the attic. This is when people start to see leaks in their ceilings and walls. 

The best way to avoid this problem is by taking preventative measures. When you’re shoveling your driveway and clearing your sidewalks, think about snow removal for your roof too. This will help to avoid any potentially dangerous build-up. If an ice dam is already forming, one easy way to get rid of it is to simply fill a pair of pantyhose with ice melt and put it directly on the dam. If you’re not used to being on a ladder, don’t even think about getting up there in the winter months. A professional can help clear any winter debris from the house safely.

These, of course, are just stop-gap measures. The only way to prevent ice dams from forming permanently 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. Having appropriate insulation and ventilation will keep your home free from ice dams and will 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.

Beware of Outdoor Remodeling During Winter Months

You might not believe it, but this time of year I get a lot of calls from homeowners who want to put on a new roof or update their vinyl siding. People often think winter is a good opportunity to do outdoor work since it’s past the holiday period and before spring sets in. As much as I hate to disappoint, now is actually a pretty dangerous time of year to do any exterior projects and here’s why:

• When the weather is below 40 degrees, building materials start to change. As it gets colder, products such as shingles can get brittle and crack or split more easily. Materials such as vinyl siding shrink, which can lead to misalignment or potential for leaks when they later expand as the weather warms.

• Another big issue is shingle adherence. Shingle sealant is activated by sun and heat. If there is not enough of either, the hold won’t be as strong as it should be, which could cause problems down the road. If the weather is too cold, we are often forced to hand seal, which can add time and cost to a generally simple process.

• Most contractors use an air nail gun for external remodeling, which works by pressure. If humidity turns to ice in the airline, it can under or overdrive the nails instead of putting them in flush. Compressors face the same potential problem. 

• Being on a roof or ladder in winter is dangerous. Even the most seasoned professionals need to take care as black ice can cause serious injury. While we take every precaution, there is a lot that can go wrong during cold conditions. It’s often not worth the risk. 

• Winter weather is unpredictable. When it rains in the warmer months, we tarp a job thoroughly to ensure there aren’t any leaks. Snow is more difficult as it adds both moisture and weight to a job. Imagine having a roof open in February and a foot of snow falls from the sky.

• A cold weather installation could void your warranty. Many products specify a proper installation environment, which is usually above 40 degrees. 

• Winter jobs almost always take longer as roofers need to take extra precautions and more frequent breaks while working in cold conditions. The last thing you want is someone on a roof who can’t feel their toes. There is also less daylight, which will add time to an installation.

Sometimes, a winter repair or replacement is inevitable, and leaving the job until spring might make things worse. If this is the case for you, be sure that you’re working with an experienced contractor who has a solid track record in winter conditions and discuss all the precautions and extra steps that will be taken to ensure the job is done properly. The last thing you want is someone getting injured or a situation where corners have to be cut to accommodate less than fair conditions. In the end, is it really worth it?

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.
