Winter Roof Damage
Water leaks from ice and snow are caused by interior heat from the house. Water from ice melting on the roof is trapped and creates an ice dam on the roof, gutters and downspouts. The water then takes the path of least resistance under the roof system, or sideways and through flashings, which were not designed to handle this kind of moisture. When this happens, interior water damage can occur.
We have seen and heard of customers using a regular snow shovel or a garden shovel to remove excessive snow from the top of their homes to prevent roof damage. This technique has some pretty obvious drawbacks, and can cause its own damage to shingles. Some contractors may suggest that rock salt or calcium chloride be used to melt the ice and snow. Unfortunately, this may also damage shingles. In fact, many shingle manufacturers warn against this, and it may void your warranty. At Scro’s Roofing Company we never recommend you get up on a dangerous roof with ice and snow and attempt to remove anything from the roof, consult with a professional local Raleigh, NC roofing company. This defiantly will void warranties both our labor warranty and manufacture warranties.
Gutters & Flat Roofs
Ice in gutters and downspouts is virtually impossible to remove without causing roof damage or harming the gutters themselves. Gutters that are filled with blocks of ice, however, are a repair waiting to happen. Make sure that your gutters are cleaned regularly to reduce the risk of getting them clogged with ice. In some cases, the gutter system may even be removed from the roof to prevent ice damage.
Flat roofs or low pitched roofs with a slow shedding of rain. The rain will freeze and trap ice/water on the flat or low pitched roof section. The trapped ice/water may accumulate to levels higher than the roof flashings, resulting in water leaks. This problem also causes the ice to be trapped under the shingle causing the shingle to lift and sometimes crack. This now allows moisture under the shingle and access to the nails that hold the shingles down. Customers usually call us when this happens and inform us that they have never had leaks previous even in hard down pours.
Dealing with Skylights
Skylights covered with ice and snow may cause leaking because of their “weep holes” being covered. Internal condensation can’t escape, causing water. Have the snow and ice removed from and around the skylight by a professional local Raleigh, NC roofing company.
