this is the first winter in a new house (to us :) We were told the roof was
redone about 3 years ago, and the professional home inspector agreed. we'd
had a huge amount of snow this year (northern ontario canada), which in turn
covered the lower profile bathroom exhaust vent. of course, being under 16"
of tight snowpack on a gently sloped roof, the exhaust was melting the snow
underneath and caused a classic ice dam.
water dripping in the bathroom indicated it, and a quick check in the attic
proved it. I carefully shovelled the roof as clean as I could get it, and a
warm spell has completely bared the south side of the roof, completely
clearing the gutters and ice dam (we've had no further problems, btw). did
this ice dam cause any permanent damage? i thoroughly inspected the roof
and see nothing that alarms me (tho I'm not a roofer :) I do see a few
spots where the shingles have been lifted up, they are staying in the lifted
position (say less than 1" up on one side) likley due to the cold. I'm told
by a roofer that once the sun warms them right up in the spring, they'll go
any opinions? anything that I should be concerned with? anything specific
to look for? if all else fails, in the spring when its warm I'm going to go
up there with roofing cement and do as the instructions say to glue the few
high ones down....the roof is in otherwise excellent condition.
