Winter weather brings unique challenges to your roofing system, often resulting in a range of common winter roof issues. Cold temperatures, snow accumulation, and ice buildup can all contribute to damage that impacts your home’s protection. In this article, we’ll explore six common winter roof issues and how to address them before they escalate.
PROBLEM #1 – CONDENSATION
When warm air meets a cold surface, condensation will occur. Unfortunately, an improperly insulated attic is a prime candidate for the formation of condensation, which can lead to mold and mildew, damaging the interior structure of your home. To prevent condensation, ensure your attic is properly ventilated. Inadequate ventilation can damage your roof, the decking, and encourage ice dams and shorten your roofs overall lifespan by half.
Problem #2 – Flashing Leaks
If you have a sloped roof like most of us do, you may be no stranger to leaky flashing. Flashing are the strips of metal that are placed along the front edge, corners and ridges of your roof and around your chimney and skylights. If not installed properly, or during a violent storm, they can start to pull away from your roofing material and lead to water leaks. Inspect your flashing about every six months to help prevent this from becoming a problem.
PROBLEM #3 – STRONG WINDS
Strong winter winds can cause significant damage to roofs by loosening shingles, tearing off sections of roofing materials, or even dislodging flashing around chimneys and vents. These high winds can also lift the edges of your roof, exposing the underlayment to moisture and debris, which may lead to leaks and structural issues over time. Additionally, flying debris carried by strong gusts can puncture roofing surfaces or clog gutters, further compromising your roof’s ability to protect your home during harsh weather.
PROBLEM #4 – TREE LIMBS
If you have lots of trees in your yard you’ve been blessed with beautiful, year-round scenery. But, this means you’re also privy to some of the dangers large trees can impose. Sometimes overhanging tree limbs can scrape the surface of your roof and damage its protective top layer. And, if branches end up falling into your roof that can cause problems too. So, to protect your home and family, make sure to trim any branches that come within six feet of your roof. It will also keep the critters from crossing the roof and trying to enter the roof for Spring nesting.
PROBLEM #5 – ICE DAMS
One of the most notorious winter roofing problems is the formation of ice dams, which can wreak havoc on your home’s roof and gutters. These icy barriers trap water, increasing the risk of leaks and other costly damage.

PROBLEM #6 – ICICLES
Icicles are also typically formed by sunny days and sub-freezing temperatures. They may look neat, but they can pose a real danger to people and pets. Often the result of clogged gutters and downspouts, their excessive weight can cause roofing and gutter damage. To discourage icicles from forming, keep your gutters clear of leaves, needles, and other debris. When the warmer weather arrives, attend to gutter maintenance swiftly to avoid leaking and other problems during spring rains.
