4 Common Problems Affecting Metal Roofs in the Winter
If your home has metal roofing, you know that this is one of the most durable materials available. However, despite its resilience, snow and ice can still damage the panels, especially in the frigid Wisconsin winter. Below are several issues that you may experience this season so that you can spot and repair them promptly.
What Winter Metal Roofing Issues Should You Recognize?
1. Leaks
Modern roofing materials include insulation that prevents them from shrinking and warping in cold temperatures. However, corroded flashing can allow water into the seams, where it can freeze and force the panels apart. Incorrectly installed panels can also separate in high winds, creating large gaps that allow water into your home. At least once a year, have an experienced technician inspect your metal roofing. They can often identify issues that may lead to winter leaks and repair them before you experience issues.
2. Ice Dams
Metal roofing is designed to prevent heat from transferring from the attic to the surface. However, if the insulation has degraded or the attic doesn't have enough ventilation, the upper portions of your roof may be warm enough to melt snow. When the runoff reaches the gutters along the edge, it can freeze, creating large blockages that force future water into the seams of the roof. The best way to prevent this is by updating the attic's insulation. Also, clean your gutters so that the water drains away from the home before it accumulates.
3. Corrosion
With proper maintenance, metal roofing can last for more than 50 years. However, if impacts damage the protective coating or the fasteners fail, water can contact the metal directly, leading to rust. To minimize the risk of corrosion, repair any roof damage as soon as possible. After major storms, inspect the surface for large gouges, as without a full coating of paint, the roof cannot resist water damage. Promptly replacing missing hardware and damaged panels prevents corrosion from eating through the metal and contributing to leaks.
4. Wind Damage
Winter blizzards can bring winds of up to 40 mph, which can fling branches and debris onto the home. While metal roofing can withstand strong storms, the panels can still come loose if the roof deck is rotted or the fasteners are missing. One of the best ways to prevent damage is by trimming nearby trees so that they are at least 6 feet away. This prevents the branches from breaking and falling on the home, reducing the chance that they will break the hardware holding the roof.
