Ice Dam Removal is Key for a Leak-Free Roof

The kind of weather we’re having can create some messy challenges for homeowners. Snowfall followed by freezing rain and sleet makes icy conditions on sidewalks, in your driveway, and worst of all - on your roof. The culmination of wintry build-up is one of the most dangerous hazards for a home because although icicles look pretty, the ice dams creating them can result in major leaks in your ceiling and interior walls.

An ice dam forms when heavy snow blankets the roof, forming an extra layer of insulation. As warm air rises from your house and up through your attic, it causes the layer of snow closest to the roof to melt and the water to slide down into the gutters. This would normally be a good thing, but because so many homes in our area aren’t properly insulated, what often happens is that the melting water hits the cold eaves of the roof, freezing again instead of draining off through the gutters. This forms an ice blockage. As that ice grows and grows, the water has nowhere to go so it starts to move under your roof shingles and eventually into your insulation and drywall. This is when you’ll start to see the leaks in your ceiling and walls.

The best way to avoid this problem is by taking preventative measures. I get calls from homeowners to remove ice dams after every winter storm, and for many, it is too late and they are already facing thousands of dollars worth of damage. But if you’re lucky enough to catch an ice dam before it fully forms, it’s a smart idea to get rid of it as quickly as possible.

Firstly, when you’re clearing snow from your driveway and sidewalks, think about your roof too. Removing snow from the house is the best way to protect your home against ice melting and refreezing in the gutters and up the roof. If you already have an ice dam forming, you can use a hammer and chisel to get rid of it, but be very careful as roof shingles are more delicate and brittle in cold conditions. One safe home remedy is to fill a pair of pantyhose with ice melt and lay it across the ice dam so the water will melt into the gutter. If you’re not comfortable on a ladder, call a professional to help you get rid of the ice dam quickly and 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. 

To all of my readers, may you have a wonderful Christmas and holiday season. I look forward to seeing you in the new year.

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!
