Prepare Now Before Temperatures Drop
North Texas is about to experience one of the colder weather events we have seen in several years. With temperatures expected to drop quickly, a little preparation now can save a lot of stress later. Stock up on basic groceries, bottled water, flashlights, and batteries. Make sure phones and power banks are charged. Wrap or cover exposed outdoor pipes, disconnect garden hoses, and know where your main water shutoff is located in case a pipe bursts. Bring pets inside, check on elderly neighbors, and plan for slower travel if roads ice over.
What Is an Ice Dam and Why It Matters
One of the most common cold weather roofing issues we see after a freeze is an ice dam. An ice dam forms when snow or ice on the roof begins to melt, usually from heat inside the home, and then refreezes near the roof edge where temperatures stay colder. 
As ice builds up along the eaves, melting water can back up instead of draining off the roof. That water may work its way under shingles and into the home. Ice dams are temporary. Once temperatures rise and the snow and ice fully melt, the ice dam itself disappears. Any remaining issues are typically related to water intrusion that occurred while the ice was present.
Ice and Water Shield and Dallas Roofs
In colder climates, ice dams are often addressed during construction with special materials. One of the most common is ice and water shield, a thick rubberized underlayment installed in vulnerable areas like valleys and sometimes along roof eaves to help prevent water backup. In Dallas and most of North Texas, roofing systems are not required to be built for snow or ice dam conditions. Most roofs here do not have ice and water shield along the eaves, and that is normal for this climate. It is commonly used in valleys because it works well as a valley liner, but full perimeter eave coverage is not standard. Should you add it during a future roof replacement? That comes down to cost versus benefit and your personal comfort level. If your roof is in good condition, there is no reason to add anything now just because of a short cold snap.
