You may think that the seals are bad between the double panes in your window but the real question is what is the cause for it? During cold winter months your furnace is working overtime to keep your house in a reasonable temperatures live in. Insulation behind the drywall and in your attic supposed to keep you warm from cold winter months. When there is no fresh air flow in your attic due to improper ventilation system, it forces all the warm air to get trapped and cause condensation .

Many may think skylight is in bad shape and needs to be replaced but it may only leak because of the ice dams that are allowing water to enter around the skylight and cause a leak.It’s like taking a shower with hot water and getting all the mirrors moist. As soon as you turn on the fan all the moist air fans out and circulates the air. Due to position of the skylight, snow does melt and freeze. Monitor skylight tunnel for yellow stains to make the call.

So on your roof there are vents designed to fan out the trapped moist air. If these vents are blocked because of the snow or they are not big enough to fan out the moist air, it will cause condensation. If you are experiencing similar effects and want some answers, contact your Ottawa Roofing Contractor  for advise. If roof vents are not visible and covered with snow, hire an  experienced roofer in Ottawa to remove all the snow off your roof.

Annual roof inspection is in every home and business owners interest and responsibility to protect integrity of the dwelling. Oil change for your is no different than inspection for your residential and commercial roof in Ottawa. Better safe is always better than too late

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.
