This Prince William County roof repair video explains how ice damming happens and how we repair it
We received a call from a Prince William County homeowner requesting an estimate for roof repair due to ice damming. Let me show you the problem that they’re having. This is just only in their master bathroom. I saw many leaks like this back in 2010 when we had that Snowmageddon, where we had a lot of sections of northern Virginia had four feet of snow.
Not only did they have the problem here in the master bathroom, they also have it in the bedroom as well. So, the next photograph will show you what we did to actually stop the leak. As soon as we arrived at the home, we instantly set the ladders up and we removed the snow along the entire length of the gutters from the gutter up seven feet. Once all this snow and ice was removed, we then removed the shingles down to the bad wood and then we had to remove the gutter. But, you can’t remove the gutter all in one piece. It’s too dangerous, because it’s way too heavy with all that ice.
So to be safe, we cut the gutter in three- to four-foot sections. If you tried to remove the gutter in a section in anything longer than four feet then it would be too dangerous and you could also rip of the roof fascia that gutter is fastened to. So to be safe we did it in three- to four-foot sections and everything came out well. Now, we install ice and water seal to the wood deck 32″ up the roof and four inches onto the wood fascia, where the gutter was fastened, too. Once that’s in position, we then installed the new gutter, making sure the gutter is secured over the ice and water sheild and then we did the roof completely along the gutter on the upper section and the lower section.
A big problem that a lot of roofers do is, when they install the ice and water shield, they don’t bring it behind the gutter. They just start at the edge of the roof line and that’s it. So, now when you have ice damming all over again the ice will lift the shingles up. It will lift the ice and water shield up like it’s not even there and then you are going to have this problem all over again. So, it’s crucial that the ice and water shield be installed behind the gutter.
To make sure they don’t have a problem again with ice standing we had to make sure that the house was ventilated correctly which it was not from the very beginning. They had no soffit intake vents and they had no exhaust vents whatsoever. So, we installed ridge vents at the peak of the roof.
Now they have proper intake ventilation and exhaust ventilation. And, another key thing is to make sure that the insulation in the attic is not pushed up too far to where the soffit is where the intake vents is, because if the insulation is pushed in there too far you are closing up the cold air from rising in through the intake vent installation from the soffits. So, you have to make sure that it’s not closing it up and there’s a proper breathing space for proper air flow.
