Ice Dams and Your Home
Ice dams. What exactly are these? Ice dams are continuous chunks of ice that start to form along the margins of your roof during the winter and super cold seasons. When these are frozen, they don’t seem to cause much harm or troubles, but what about when the the warmer part of the day comes along during the cold day and these begin to melt? Water melting off the roof begins to pool behind the ice and can seep back up under the shingles of your home. That melted ice will eventually drip through the roof onto the soffits, walls, and your worst nightmare: the ceilings.
We all know how frustrating and can be to have ice dams on our home and maybe you are not too worried about it right now but although winter is not here yet, it will be sooner or later. What better thing to do than prepare yourself and your home before it is too late to start?
First off it is very important that you know how these ice dams form. These occur after a very heavy snowfall when the warm air inside your attic causes your roof to warm and therefore the snow begins to melt. This running melted water then freezes once again once it gets to the colder roof edge, which then forms a mound of ice. The ice there now traps that melted water which from there on seeps back up the shingles and now is dripping through your home ceilings making your ceiling to stain, be wet and potentially rot. Sounds like a lot for something we may
sometimes pay no attention or importance to right?
So what can you do to prevent all this worry some fuss? Stop these ice dams with a cold roof. That’s right, a cold roof. The formation of ice dams and icicles as read above, occurs only when part of your roof warms about 32 degrees F, and this created what is known as a warm attic.
The heat escapes from the ceilings into the home’s attic and warms up the roof and shingles that are located just above it. The outdoor temperature can be freezing but due to that warm section the snow melts. So with a cold roof as we mentioned, after a snowfall, it will have a thick blanket of snow not melted spots.
You can have a cold roof with proper insulation. It is very important and essential for you to have a thick enough insulation level and that is where the R-value is so very important. Although there are many insulation options in the market it is very important that you seek and use the one with the best R-value. Amongst the best known is spray foam insulation.
