Roofing in the Winter is a challenge. Yes. When done correctly and by skilled professional roofing contractors, roofing in the winter is able to be performed successfully. However, sometimes it’s necessary. Winter roofing is particularly dangerous.
If you think that your roof may need to be repaired due to ice buildup, you are right. The risk for roofing problems increases dramatically in early winter when temperatures are near freezing. As temperatures dip below freezing, roofers may need to use additional measures. If ice has accumulated on the roof, then there may need to be some roof repair or removal work that needs to get done. It’s always better to catch problems before they become too big and expensive.
Roofing shingles, especially in the case of snowed-in roofs, are especially susceptible to damage in the cold weather. Over time, the rubber and canvas backing on shingles can degrade. If left unfixed, this degradation will expose the underlying metal underneath. If left unnoticed, this could cause quite a mess as the resulting leak may not only be inconvenient but also hazardous.
Once you’re certain that you’ve had a cold weather related roof repair problem, you should find out the best time to have it done. Depending upon where you live, roofing professionals may suggest that you wait for the weather to warm up again before having your work done. This is true whether you live in Seattle, Salt Lake City or anywhere else. The best time to repair a roof in the winter is when temperatures have warmed up to at least 60 degrees.
Keep in mind that roofing materials such as tiles, asphalt and slate are particularly sensitive to temperature changes. When temperatures drop below freezing for more than a few minutes, they begin to become brittle. Asphalt and slate roofing materials become brittle when temperatures drop below freezing for at least three hours. And if the temperature drops any lower than this for more than five minutes, any roofing materials are no longer safe to use.
Another thing to keep in mind is that some roofing materials are best installed during the day, when temperatures are cooler. By removing insulation from the attic area, you may also be able to extend the season by several days. This is especially true for fiberglass and aluminum roofs, which are typically best removed in the spring, summer and fall months. If your roof isn’t being installed during the spring or fall months, consider waiting until temperatures start to rise again before you do any work. Doing so will help to ensure that you’re not causing any damage to your home while trying to install your roof, and it will also ensure that the installation goes as smoothly as possible.
Roofing materials that are designed for use in cold weather are not necessarily designed for use in warm weather. Always consult with a reputable roofing contractor when choosing these products. In particular, always choose metal roofing over asphalt or slate due to their tendency to expand and contract when temperature differences are present. Also, avoid using rubber as an insulator, as it expands too much when the temperature rises.
Roofers recommend leaving the valleys between rows of shingles flat, even after they’ve been installed. This will help prevent valleys that run parallel to the structure of your roof from becoming too high, which could cause leaks and damage to the roof. It’s also important to pay close attention to your valleys as they form. Asphalt and slate typically don’t form valleys, although this may vary depending on the area.
