Winter in Ottawa has gotten more severe in the past few years. Sudden thaw and freeze has been causing freezing rain accumulation over the years.

As a homeowner it is that time of year to take a good look around your house and make sure there isn’t any massive icicles hanging around. It can be really dangerous depending on where it is located. If the ice dam/icicle is located above any doorway, steps or parked cars etc… contact a local roofing company to have it removed safely.

There are lots of older homes in Ottawa Ontario that does not have significant ventilated soffit installed to increase the fresh air flow into the attic. Majority of the older homes did not come with that feature and those homeowners replace the roof way more often than they should.

Roof vents are designed to help all the fumes, hot air from your attic to escape so that the temperature of your attic is same or similar to outside. In order for the roof vents to work properly it requires fresh air to enter from the soffit. When there is no intake/fresh air entering the attic ventilation process is very slow maybe even non. You can install as many vents as you like but it requires fresh air to create a force to complete a cycle.

During winter months it is very easy to point out which house does not have proper air circulation just by looking at the ice dams. When the snow covers the vents on your roof it suffocates your attic and that causes condensation, forces the hot air to exit from the soffit instead of the roof vent itself. Hot fumes exiting from the soffit creates a thaw action daytime and allows it to freeze overnight. After few weeks of that will give you a massive ice dam that will form along the eavestrough and it will work its way along the metal valley. It can get messy once this ice starts to melt and cause major water damage to the houses.
It is not a very big job to do but there are only certain roofing companies who will be able address that issue. Many roofing companies would want to get paid for removing ice dams instead of fixing the lack of air balance. We offer residential and commercial soffit and fascia sales, installations, repairs and services in greater Ottawa region. We also do offer free quotes and estimates to potential customers who is experiencing that types of problems.

I have to admit this past week was extremely crazy. My phone did not stop ringing for the past 5 days because of all the houses that got flooded because of the ice dams.   Homeowners starting to understand the importance of a good quality roof instead of a quick fixer upper. The money they saved on the roof replacement plus few more thousands to the repairs to correct the issues and maybe a new roof. Ice dams does not form on its own. It requires either direct sunlight or heat loss thru your attic to form ice dams. Proper ventilation is one of the issues. When the vents get covered by snow, it makes it harder to vent our or even does not vent out at all. When the hot air gets trapped in your attic if will push back thru the ventilated soffit and start to form ice dams along the gutters. Hot fumes will melt the snow and turn it into ice over night. Eventually it gets bigger and wider. Whenever there is a warmer day, snow melts and it polls up behind the ice dam. It wont take a long time until you can see it dripping from your ceiling.
Here is my advise to the homeowners, don’t try to save couple of hundred dollars during replacing your roof. Make sure drip-edge is installed along all the edges. Depending on the slope of your roof have ice and water shield installed at least 6 feet from the gutters maybe more if needed. And have the rest of the roof covered with felt/tar paper or anything similar.
When we replace a roof our minimum usage of ice and water shield is 6 feet. Regardless of what the slope is, it is our company policy install 6 feet of ice and water shield and 100% felt paper and of course maximum ventilation.

Did somebody say winter? Yes you heard it right winter. It is that time of year cleaning the front and back yard few times until there is no more leaves left to rake.

You don’t necessarily need to be living beside a lot of trees but the wind has its own method of drifting. Cleaning around the house gives every home a fresh and clean start when the spring is knocking at the door. But before we go to fast, we need to make it thru the winter first. It takes a lot of dedication to take all the necessary steps to protect yourself and your loved ones from the cold winter days. For starters make sure your hydro and natural gas bills are paid up to date for any surprise delays during cold days. Your roof is in good shape and has been inspected by a professional roofing company. Any branch that is leaning towards your roof is a potential danger so trim it down. All the gutters are free from leaves, debris and maybe tennis balls. It may sound strange but I’ve seen it too many times. A clogged drain is a first element of a massive ice dam that could destroy your home and cost you a chunk. Make sure all the drains are functioning and water is being guided “away” from your foundation.

If you have a low-pitched roof that is facing north, be sure to keep an eye on it because it can get messy especially when the thaw begins. Roof rakes are good to have but always hire insured and experienced roofing companies to perform the risky stuff, don’t take a chance. If you notice a leak, call your local roofing company to remove all the snow and ice off the roof.
