Ice Dams From Early Snow Can Cause Major Problems All Winter

Early snow, a quick warm-up, and an immediate deep freeze had my phone ringing off the hook this week with requests for roof leak repairs. Ice dams are building up on people’s homes and causing big-time damage, which is a major headache right before the holidays. 

Are you scratching your head? Let me give you some background. An ice dam forms when heat from inside your home causes snow on your roof to melt. That melting water begins trickling down towards your gutters, which sounds like a good thing, except that in many homes, the temperature at the top and bottom of the roof is so different that the water refreezes at the gutter line, causing a mass of ice. When the water has nowhere else to go, it continues to expand, pulling up shingles and seeping underneath the roof. 

Why do so many homes have such a variation in temperature between the top and bottom of their roof? We all know that heat rises and when your house isn’t properly insulated or ventilated, the heat from the living areas of your home rise into the attic, hitting the highest temperatures in the very peak of the roof. So it’s no surprise that snow begins to melt at the highest point, where the temperature can easily rise to 32 degrees Fahrenheit or melting point. As the water makes its way down the roof, the temperature decreases; enabling the water to refreeze by the time it finds its way to your gutters. As that water builds up, it begins to form an ice dam. 

Have you ever seen a house with big beautiful icicles hanging from the roof? Those icicles aren’t just a pretty bi-product of winter weather; they are a sure-fire sign that an ice dam is forming. Ice dams can be a real problem, especially in older homes that aren’t properly insulated and ventilated. As the water builds up, it can leak into the house and cause damage to the walls, ceilings, insulation, and other areas. Additionally, an ice dam that is melting can channel water down into the foundation, which can cause leaks and mold formation in the basement. 

Worried about ice dams damaging your house? Next week, we’ll talk about ways to temporarily fix them, and what you can do to ensure they don’t pop up again next winter.

Warmth Seeking Pests Are a Common Nuisance As the Cold Sets In

The first sign of an animal intruding in your home is likely the noise. Late at night when all should be quiet, you might be woken up to squeaking, rustling, or even hissing somewhere above your head. As the nights start to get cold, mice, rats, raccoons, possums, and other small animals start looking for warmer shelter, and attics are a popular place for them to reside. What’s important is to take action quickly, before they start to get too settled in and begin to nest where they shouldn’t. 

Generally, the noise that the animal makes will tell you what you’re dealing with. Squeaking or chewing sounds are likely rats, scurrying is probably a squirrel or mouse, and snarls or hissing is usually a raccoon. While some of these animals are looking for a place to call home, others may have ended up in your attic by accident and are looking for a way out. It’s a good idea to know the difference. 

Almost all animals are likely to chew through wiring and bigger ones like raccoons or possums can tear apart insulation and ruin ductwork. Even small mice can make unwanted nests and leave an awful smell with their excrement. Although dealing with animal removal is a pretty awful job, leaving an unwanted visitor alone will end up costing you a lot more than sleep. If removing pests isn’t on your resume, call in an exterminator to take care of the problem. 

If you have mice or rats, they have likely moved in because there is a water source. Simple bait traps will help get the ones that are already there, but a mouse can fit through a hole the size of a dime, so rodent proofing is essential. You’ll also want to inspect for any roof leaks as part of the job.

Squirrels are one of the animals I mentioned that might have come in accidentally. They usually prefer it outside and will be looking for a way to leave your home. Soffits and vents are likely places for squirrels to be able to get in so your best bet is to install an exclusion door that lets the rodents out so they can’t get back in. 

A one-way door will also work for raccoons, who don’t mind sticking around if they find a warm, dark and comfy place to live. However, since raccoons are nocturnal, you can make your attic less accommodating by leaving the lights on and even playing music. They’ll soon look for somewhere else to live. 

Bats are elusive in that they are very quiet and you might not even hear them unless there is a decent size colony making their home in yours. Removal is key and should only be done by a registered DEEP specialist as bats can be diseased. 

Finally, there are possums which, similar to raccoons, won’t want to leave. These guys are pretty resilient and they go to the bathroom everywhere, leaving a huge smelly mess behind. The best method to get rid of a possum is to have it trapped and removed by a professional. 

Happy animal proofing!

What's Under the Roof?

I recently did work for a homeowner who got the shock of her life when we removed her old roof and found sheet after sheet of black, rotten plywood. The homeowner couldn’t believe it and asked me how the plywood could be so damaged if she had never had a roof leak. 

The answer is quite simple and a lot more common than you think. In our area of Connecticut, nearly all attics don’t have enough insulation and aren’t ventilated properly. I meet people who need a new roof and want me to just lay an extra layer of shingles over top of what they already have to save money. What they don’t realize is how much deterioration exists that they simply can’t see.

With a roof, airflow is absolutely crucial. Attic ventilation allows your home to “breathe” by taking in air from the outside and letting out air from the inside. Too many homes that I work in aren’t properly ventilated, in fact, most have their bathroom and even dryer vents going into the attic instead of outside. In order to have proper ventilation, your home needs a system that includes intake ventilation through the soffit or a new product called SmartVent which is installed on top of the roof near the gutter edge. Louver vents were typically used at an exhaust vent in the 1950’s and 1960’s but now ridge vents are more common. If your house has both louver vents and ridge vents, the louver vents should remain closed, otherwise, the louver will act as an intake vent and will only cool the top third of the attic. 

In the colder months, it’s not uncommon for me to see frost on attic plywood because of subpar insulation. Insulation and ventilation work hand in hand - the ventilation controls the airflow and the insulation controls the temperature. You’re probably familiar with insulation - it’s a cotton-looking fiberglass material that often comes in pink or yellow rolls. It can also be loose-filled into tough to reach areas with a blowing machine. Remodeling professionals use insulation between walls, in attics and in basements to retain heat in the house in the winter and keep it cooler in the summer. However, without proper ventilation, the insulation is just as susceptible to moisture and deterioration as the plywood.

My customer didn’t venture into her attic, so she never noticed the problem. What she thought was a simple roof replacement ended up being a bigger job simply because after years of decay, the plywood she had was no longer strong enough to properly support the new roof. Ignoring the problem would have voided the new roof’s 30-year warranty.

The lesson for this week? If you’re going to reroof your home, make sure that the plywood is healthy and that your contractor has given you a thorough plan to ensure that your home is properly insulated and ventilated. It might cost a bit more today, but it will regulate the heat and cooling in your home for years to come, saving you on energy costs and giving you more comfort as well as peace of mind for the health of your house.
