Can Roofing Tar Be Applied in the Rain?

It is not recommended to apply roofing tar in the rain or high humidity. Tar needs dry conditions and direct sunlight to cure properly, usually at least 8 hours. Applying tar in wet weather can prevent it from adhering and drying correctly, compromising its effectiveness and longevity. Wait for clear, dry weather to ensure the best results.

It is possible to apply the roofing tar when it is raining out. If the roofing professional chooses to go with rubberized tar, this is often designed specifically to be applied in the rain. You will just need to clean the area before applying it to the place that you would like.  Montclair Roofing, a roofing company in Montclair, New Jersey, advises If you are not using rubberized tar, then you need to wait until it stops raining and the roof is dry.

There are a lot of nuances that can happen when it comes to your roof and it can often depend on the material and even the product that is used. This is why it is often a better idea to hire the professionals to get it done to keep things safe. Let’s take a closer look at the best time to apply roofing tar to get your roof done.

Should I Apply Roofing Tar in the Rain?

This can be a complicated question to ask. It may seem straightforward and easy to work with, but it often depends on a number of factors and what type of material you would like to use. If you or your roofer decide to use rubberized roofing tar, then it is generally fine for you to choose to apply it in the rain.

This tar is made for applying in any weather and will not slide off. Just take the time to clean off the area you plan to apply the tar on before you do the application.

However, if you decide to go with a traditional tar (not rubberized) then it is best to not apply it at all when there is rain or when the roof is wet. This type of tar is not going to stick to the surface you are applying it to, and will slide right off, giving you more work to do in the end with your roof.

So, the easy anger is that yes, there are some types of roofing tar that will do well in the rain and you can apply them in any type of weather. But this does not hold true for all types of roofing tar, so it may be a better option to avoid using it until the weather is a little bit nicer out.

Ideal Weather Conditions for Applying Roofing Tars

Notes:

• Traditional tar requires warm, dry conditions for proper curing and adherence.
• Rubberized tars can be applied in light rain but not heavy precipitation.
• Cold-applied tars allow application in cooler temps but still need dry surfaces.
• High humidity can impact drying/curing times for all tar types.

What is the Ideal Weather for Applying Roofing Tar?

If you have the choice, it is best to have at least a few days of sunshine, days without any rain or snow, before you add tar to the roof. This ensures that there is nothing on the roof to prevent it from sticking and gives the tar time to cure before anything comes to take it off. Try to get as many days before and as many days after that are nice and sunny before you decide to do the tarring process.

Most roofers are going to do the tarring in the summer, so the temperature is going to not play as big of a role here. It is ideal if you can get it to the 70 degree mark, or higher, so that the roof is warm enough to hurry the process along. It is possible to apply the roofing tar when it is a little bit lower, but it will take longer to get the work done.

And you should be careful about it getting too hot on the roof because it is possible that it will melt the roofing tar, causing it to drip and making a big mess for you to clean up later.

Choosing the Right Time to Apply Roofing Tar

If you choose to do the roofing tar on your own, it is often a good idea to have a nice, sunny and warm day to do this. But if you are hiring a professional, they can step in and get the work done for you to avoid problems. This is why it is so important to choose the right professional from the start to take the worry off and give you some peace of mind.
