One of the challenges of the winter season is addressing roofing problems, as fewer roofing contractors are available by then. Knowing potential roofing problems in the winter lets you anticipate them and address possible causes before they can happen. The following are some of the common winter roofing problems.
Blocked Plumbing Vents – Plumbing vents could get blocked by snow, which can be risky because it could allow sewer gas to linger in your home. In addition to the bad smell and sanitary issues, the methane gas also poses a danger of being accidentally lit. The plumbing vents at the roof should be tall enough avoid getting blocked during heavy snowfall.
Ice Dams – Ice dams form at the roof edges, though the actual cause of ice dams begin closer to the top. The combination of poor attic ventilation and insulation results in heat getting trapped in the attic, which raises the roof’s outer surface temperature. The melted snow flows down the roof, then refreezes as it reaches the roof edge. This cycle repeats until an ice dam is formed. In addition to the water intrusion risks, icicles can also form, which is dangerous to anyone who happens to walk under the eaves. Clogged gutters can also aid in their formation and investing in gutter guards can help.
Cracked Shingles – Certain types of asphalt shingles, such as those that are not designed for winter use, can become brittle when frozen, and can crack at the slightest impact. This is why it’s important to choose a local contractor like us who hold manufacturer certification. Since our roofing supplies are provided by manufacturers such as GAF, CertainTeed, Owens Corning® and TAMKO®, we can ensure that the roofing materials are designed for the local climate.
Flashing Leaks – Flashing refers to the strips of copper, plastic, or galvanized steel that protect valleys, skylights, and areas where the roof meets a wall or dormer. If the flashing is improperly installed, knocked out of place, or is missing, you run the risk of leaks during winter. Thorough roofing maintenance and timely repairs will address this and other potential roofing problems.
