Can you seal a roof in the winter?

Dew and fog can interfere with coatings and damage them if they don't cure properly. Coatings should be stored between 40° F and 90° F. Do not leave coatings or sealants on the ceiling if temperatures are expected to fall below 45° F. Applying roof coverings in cold climates is certainly feasible, but it can be a bit like walking through a minefield.

While most roof coverings can be applied when the temperature drops, freezing temperatures, snowstorms, and the like can make it especially difficult. Not only should you ensure the proper storage of the products and follow the application instructions to the letter, but you must also take into account a variety of factors. Everything from the condition, color and temperature of the roof surface to the air temperature before, during and after application. When it comes to repairs, almost any repair of any roofing system can be done as well in winter as in summer.

When a lack of heat prevents an immediate seal between the shingles, putty can be used to provide this seal. Letting shingles stay away from the roof during the winter is a good way to turn a minor repair into a major one. Once snow accumulates on the roof, repairs become extremely difficult and melted snow can cause large amounts of water to reach the drywall, adding internal damage to external damage. It should not be forgotten that melting snow can cause leaks where rain would not.

The classic “ice dam” is one example, but the generally winding path followed by water that melts under the snow allows it to find ways to enter the roof system that a constant rain could not. Yes, the snow closest to the roof will melt before all the snow above it, creating a layer of water between the shingles and most of the snow, caused by heat loss from inside the house. Expect the roof to leak every time the snow melts on the roof, not just at the end of the snow melt. Homeowners should consider the weather before a major snowfall as their “last chance” to avoid potentially devastating consequences as a result of known roof damage.

Now, I don't want to back down, but I would like to say that we've done a lot of successful roof repairs, even with 6 inches of ice on flat roofs, for example, in Montgomery Village, Maryland, where there are a lot of townhouses with flat roofs. Needless to say, these repairs would have been relatively easy “before the ice storm”. However, in cold temperatures, roofing equipment must hand seal each tile to ensure that the sealant adheres properly. In other words, they cannot rely on the natural heat of the sun to activate the seal.

As an experienced roofing professional knows, hand sealing takes a little longer, but ensures that each and every one of them is sealed. If you notice your roof leaking in winter, what can you do? The key is to identify the problem in time, then call a professional to repair it or offer a temporary solution and schedule the repair for the spring. If your roof was damaged during a storm due to high winds, hail, or a falling tree branch, you could have removed the shingles and left the roof deck exposed to water.

Professional roofing contractors have the resources to tear off the roof and replace it during the winter months. In cases of extreme roof damage due to the hazards of winter conditions, a complete roof replacement may be necessary. Even fixing a slowly leaking leak can take several hours of a roofing contractor's time, and this is mainly due to removing mountains of snow from the flat roof. It is not recommended to install any roof coating, whether water-based or solvent-based, at sub-zero temperatures, as rainfall on the roof will not be as evident.

If you're going to do the repairs yourself and use tar, you could use a flashlight to warm up enough to stick to the roof and roofing material. And if you're worried about how long your roof will last, you should only work with a roofing company with a lot of experience that backs up your work. If you call and talk to roofing contractors, some may tell you that it's never OK to replace a roof in winter or when temperatures fall below freezing. Metal roofs that require roofers to carry large panels across the roof can be complicated by strong winter winds.

Many people may need to do roof work during the colder months, and yet they wonder if doing roof work during this period is a good idea. As with any roofing product, be sure to store Ecodur roof covering properly, in a dry place at room temperature, so you're always ready for your next project or repair. While roof coverings are usually part of any roof replacement, every product reacts differently to cold weather.
