Trying to find the answer to “how long does it take for asphalt shingles to seal”?
With warmer weather comes the start of many home improvement projects, including roof repairs and replacement. Aside from it being difficult to work on a roof that is covered in snow and ice, roofs tend to be replaced in warmer months because heat is necessary for shingles to seal. But, how much heat is really needed, and how long does it take for your newly installed shingles to seal?
Sealing Asphalt Shingles
Sealants on shingles are not of the “peel-and-stick” variety. When shingles are installed, they require a period of sufficient RADIANT heat for activation of the sealant.
As we discussed in our blog “Is It Okay to Roof in Cold Temperatures?” radiant heat – and not air temperature – is the key to shingle sealant activation. Radiant heat refers to the heat that “radiates” from a warm object (e.g., the sun) to people or objects (e.g., your roof). Even on cool days, the sun can warm surfaces such as your skin and your roof. If it is 30 degrees and sunny, your roof can be over 100 degrees, allowing your shingles to seal even if installed when it is cooler out.
The tricky part about this is estimating the length of time it takes for activation to occur in your shingles. This is because sealant activation depends on a number of factors, including where your home is located (e.g., under a bunch of shady trees or in full sun), the direction your roof slopes are facing (in the northern hemisphere, the south facing slopes will receive the most sun, and thus, the most radiant heat), the slope of your roof, and the climate you live in.
Many shingle manufacturers have added substances that enhance the sealants “tackiness” and hardiness, making them seal more quickly, in more adverse conditions. If your shingles were installed correctly, you should have nothing to worry about.
Getting the Most Out of Your Asphalt Shingles
Getting shingles to seal is just one of the many reasons why it is so important to hire a reputable contractor who will stand behind their work with a workmanship warranty! When you hire a quality roofer, you can trust that your shingles will seal and you will have not have to worry about your roof for years to come.
