Finding out you have a leak in your roof is always a bad experience, but it’s especially bad if it occurs in the middle of winter. If you own a home with asphalt tile roofing, the tiles or shingles must form a seal so they can perform to their maximum capacity. In order for the seal to form properly, there are a few important conditions that must be met.

Understanding Asphalt Shingles
When it comes to roofing material, asphalt shingles are certainly one of the most affordable. In addition, they tend to last approximately 30 years, making them a wise investment for your home. The reason they last so long is that they include a special self-sealing adhesive strip that can be found on the top of each individual tile. As the roof is installed, the adhesive strip forms a permanent barrier with the underlayment. This prevents water, dust, and other debris from penetrating the shingles and it holds them securely in place, even during high winds.
Temperatures to Seal Shingles
If you need a new roof in the winter, it’s important to know what the manufacturer’s requirements are to make sure that the shingles are properly sealed. First, the outside temperature on your roof must be at least 40 degrees F for at least 24 consecutive hours. If it is not, the adhesive strip won’t activate, and the shingle will not be sealed correctly. When it’s cold outside, the adhesive is left open to being exposed to problems like accumulating dirt or water. These elements can completely ruin the seal. Some manufacturers will not provide warranty coverage for shingles applied in cold weather, so be sure your installer knows the proper specifications before you decide on any installation or repair.
Problems with Cold Shingles
If the weather is too cold, your shingles could crack on the back when they are nailed to the plywood. This can cause your roof to leak or even fail. It often depends on the material of your shingles as well. For example, fiberglass shingles tend to have more issues in cold weather and should always be installed directly on a warm surface. If the plywood is not warm enough, the nails could break the seal of the shingles or even back out of the wood. In some cases, roofers will store your shingles in a warm location and then bring them out to install in small batches. Others will not install a roof in winter at all due to sealing issues. Unless you’re encountering a serious emergency with your roof, it’s always best to have them installed during the warmer months whenever possible.
