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.

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.

When installing asphalt shingles during colder temperatures for example, one of the primary concerns is that they will become brittle and even break during a shingle installation, as has been known to happen when installing fiberglass shingles in particularly cold weather. 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.

Now when installing or providing maintenance on a shingle or shake roof during the summer season, the obstacle many homeowners face is that the heat makes the materials over- malleable and causes the adhesive component to dry out quickly. 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.

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!
