Help! I Have Icicles in My Attic

Not long ago I received a question from a reader who lives in an older home in the Bristol area. She wrote to me because she had gone to get something that was stored in her attic and noticed that there were icicles hanging off the framing inside. She wasn’t sure how they got there but she was worried and reached out to ask my advice. I’m so glad she did.

It might be hard to believe that icicles can form inside the house, but in many older homes that lack proper insulation and ventilation, the attic can become a magnet for condensation, which will freeze when it gets cold enough and the moisture has nowhere to go.

We all know that heat rises, and when we heat our homes in the winter, a lot of that warm air moves up through our ceilings and into the attic, rising all the way up to where it should be able to pass through the vents to the outside. However, if those vents aren’t working properly, the condensation and air have nowhere to go, so it collects on any cold surface below the dew point and turns into frost. After a while, this frost builds up to form icicles. The more moisture that builds up in the attic, the worse the problem will become. As temperatures rise and that ice and frost start to melt, it can saturate your insulation with water, causing mold and mildew problems as well as potential leaks in your ceiling. What’s worse is this isn’t even just a winter problem. Condensation build up can cause issues in your attic all year long.

So how do you stop the condensation from forming? Your first move is to look for sources that are pushing excess warm air into the attic. If you have a whole house fan, it’s a wise move to cover it as the louvers are letting your valuable heat escape quite easily. Bathroom fans are another sure bet for letting air through and they will cause major condensation issues if they are blowing into the attic instead of venting directly outside. Finally, make sure your folding stairway is covered over with an insulated box or weather stripping to avoid losing that extra heat.

While sealing off places that allow excess heat to get into the attic is a great idea, the one thing you never want to do is seal off your attic vents. Attic ventilation is a system which includes intake vents in the soffit and exhaust vents at the roof’s ridge. If these vents get sealed or blocked, there is nowhere for the condensation to go, so it gets trapped and can easily manifest into a leak. Believe it or not, the average family of four generates two to four gallons of water vapor each day from cooking, cleaning, showering, laundry, and breathing. If that water is left sitting in the attic, you’re going to have a problem.

These freezing temperatures give you a great opportunity to take a look up in your attic to see if you have any frost or icicles culminating in your home. Next week I’ll tell you more about how to properly ventilate and insulate an attic to make sure your property isn’t prone to leaks and other condensation-based damage in the future.

Don’t Let a Poor Installation Void Your Roof Warranty

If you’re like me, you’ve been keeping an eye on the situation in eastern Connecticut where over 30,000 homeowners are dealing with cracking and crumbling foundations. It pains me to see people wrestling with insurance companies and pleading with government agencies for assistance, all while worrying if they’re safe sleeping in their own home at night.

When it comes to building or remodeling a house, two of the things many homeowners rightly need to worry about are defective products and improper installations. After 40 years of being in business, I know all too well how a job that's incorrectly done can cause a homeowner time, money, and headaches that could have easily been avoided if the job had been done right in the first place

About one-quarter of the jobs I get called to today are to inspect a roof that has been installed incorrectly by someone else. A homeowner will call me up wondering why their brand new roof is leaking, or why there is mold growing in their attic, and I have to give them bad news. Not only was the job done wrong, but their product warranty is also void.

Choosing to get a new roof can be a nerve-wracking process, but even more so if poor installation ends up leaving you with a useless warranty and a massive out-of-pocket expense. Most roofing manufacturers offer a 30-year warranty on their products, but that peace of mind is only good if the installer takes the correct measures to properly ventilate the attic. Without that ventilation, you can kiss your warranty goodbye.

Ventilating a home enables good air to get in and bad air to get out. A ventilation system is comprised of 50 percent intake and 50 percent exhaust, whereby air can get pulled in under the eaves of a home and can escape at or near the peak of the roof, ensuring there is constant circulation and no threat of moisture buildup or too much heat.

If moisture builds up in the attic, mold spores will begin to grow. Excess heat will feed that mold, enabling it to colonize and infiltrate the insulation and wood in your attic. In the winter, moisture can become frost, which will melt as the air warms, causing “rain” to seep down into your walls and ceiling. If you think these issues sound rare, they’re not. Only 10 percent of homes are properly ventilated, which is partially due to poor education on the importance of ventilating a home, and partially due to “cutting corners” during the installation process.

Sometimes, when dealing with a faulty product like those folks in eastern Connecticut, there is very little a homeowner can do. But if you’re in the market for the big remodeling job, you as the homeowner can always ask questions, do your research and understand the steps necessary to ensure that your roof, siding, or other home improvement job is being done correctly. For us pros, an educated homeowner is the best kind of customer.
