As a homeowner you have likely wondered about some of the basic roofing maintenance fundamentals and what to do in order to best prepare yourself for any roofing project in general. One particularly common question asked by homeowners when it comes to roofing projects, is what, if any, is the ideal roofing temperature for performing roofing maintenance or a roof installation?

Since the temperature directly impacts how well roofing materials like asphalt and fiberglass shingles work, it is imperative to plan strategically when going about a roofing project. With that being said, let’s take a closer look into how and why the roofing temperature can affect the overall quality of the roofing job itself.

 

When is it too cold to put on a roof?  

The cold weather can be bad news for your materials. Some types of materials can turn brittle during the process. One of the more delicate shingles in the cold is fiberglass shingles. If the shingles become brittle, it is going to be difficult for the contractor to lay them down in your roof. A lot of damage can be sustained during the process, and it might cause the homeowner more money. Installing shingles in the cold weather necessitates extra caution. Aside from the brittleness of shingles, the adhesive might be affected as well. The adhesive may not work as expected since it may lose its stickiness due to lower temperatures. Make sure that roofing installation is not done when the weather drops below 40 degrees Fahrenheit.

If you have no choice but to install a shingled roof during the winter season, take these tips into consideration:

  • Store the shingles in a warm location right up until you are ready to transport them to your roof.
  • Efficiently cluster the shingles together on a cart to transport them quickly, and with less likelihood of them cracking as a result of too much handling.
  • Apply a conservative amount of adhesive to the back of the shingles to help them stay in place and protect them from high winds, and firmly adhere the shingles to the roof’s surface.

When is it too hot to install a roof?

It is another issue when the temperature spikes up. One particular problem that contractors encounter is the quick drying of the adhesive. It can be challenging to lay down the shingle accurately piece by piece if the adhesive keeps drying out fast. Depending on the material you have chosen, shingles may soften and lose their original shape. It can be harder to install if that such a thing happens. The heat may alter the shape and edges. This change may result in the difficulty of installing them side by side with accuracy and precision. The best way to avoid this issue is to install roofing between 40 to 80 degrees Fahrenheit.  

When is it too hot to do roofing

Keep in mind the following if you are considering a roofing project during the summer months:

  • High humidity levels can make it nearly impossible to get the shingles to adhere properly to the roof, and if shingles are not installed properly, they can easily be torn off by a gust of wind.
  • Avoid keeping your shingles in direct sunlight right before installation, as they will become very difficult to work with once they acquire heat.
  • Make sure to perform the job outside of the peak heat hours during the summer, which are from noon until 4 pm.

What is the best temperature for installing a roof?

Professional roofing contractors generally agree that while roofing projects can be done in any temperature, most experts advise against roofing when the temperature drops below 40 degrees, or when it climbs to higher than 85 degrees. Now you may be asking yourself, what are the reasons why the temperature has such a strong influence over the way a roofing project turns out? The short answer to this is that the properties of roofing materials make them susceptible to physical changes during installation and repair if the surrounding temperature is either too hot or too cold.

 

Ideally, the best temperature and conditions under which to work on a roofing project or installation would be around 55 degrees, with mild humidity, low wind speeds, and no rain. However, when in doubt, don’t hesitate to call your local Bay Area roofing company for further advice and assistance!
