Roof Design:Flat roofs are at the greatest risk from roof snow load damage, whereas a steeper incline (pitch) roof allows the snow to fall more easily off the roof. Experts suggest having a roof pitch of no less than 1:12 if you live in a heavy snow-prone area. Risks of Excessive ...

PREVENT WATER & ROOF DAMAGE Oftentimes, it is not the ice dams themselves that cause the most damage to your roof; the real worry comes from the melted snow or ice that has seeped into cracks on your roof and then froze again. This is where the damage begins. The water that has pool...
blocking snowmelt farther up from running harmlessly toward your gutters or the ground. Instead, the liquid soaks into your roof and attic, resulting in potentially serious water damage. The cause of ice dams and icicles is similar -- snow on the roof is warmed enough to melt, and then re...
The handle assembly may be gripped by a user who is not located on the roof to pull the snow moving surface from a position on the interior of the roof towards the eaves of the roof to remove a swath of snow. To prevent damage to the roof during this snow removal operation, the ...
A heated roof valley device for melting ice and snow accumulating on a roof valley including a generally "V"-shaped lower casing and a corresponding "V"-shaped cover positioned in spaced-apart relation to the lower casing. An electrical heating element positioned in the space between the lower...
(NRCA) recommends that some snow be left on the roof in order to prevent damage to the shingles. That way, the contractor’s shovel doesn’t come into direct contact with the roof, so it won’t scrape it. Remember that only a professional can safely remove snow from the roof with a ...
