A common roofing material chosen by homeowners is asphalt shingles. Shingles add an additional layer of protection to homes by keeping the wind and rain out of them. They are robust and resilient in all types of weather, including severe storms. Their strength, though, lies in their ability to function as a unit. Homeowners who are thinking about installing a new roof might be curious about how long it takes for asphalt shingles to seal.
In this blog post, we will learn more about how long it takes asphalt shingles to seal and the significance of this timeline for a durable and long lasting roofing system.
How Long Does It Take Asphalt Shingles To Properly Seal?
Sealing your roof after installing asphalt shingles can take several hours or even weeks. A number of things can influence this, but the weather is the most significant factor. Asphalt shingles adhere to one another more quickly in warm weather—sometimes even in a matter of hours. However, if it’s colder, it could take them a full day, several weeks, or even a month to seal correctly.
What Is The Best Temperature For Asphalt Shingles To Seal?
For asphalt shingles to seal, a temperature range of 45 to 85 degrees works best. The shingles properly stick to one another and form an impenetrable seal within this range.
Warmer weather promotes the bonding of the shingles to the roof, whereas colder temperatures can keep the adhesive inactive, leading to poor adhesion and potential issues down the line.
While cold weather makes asphalt shingles brittle and increases the chance of cracks or breaks during installation, warmer weather makes them more flexible and easier to handle.
Direct sunlight also helps the shingles settle and seal, creating a bond that keeps water out and maintains the lifespan of the roof.
Are Asphalt Shingles Self-Sealing?
Asphalt shingles don’t naturally seal on their own, but they often come with a temperature-activated adhesive strip that is applied during manufacturing. Here’s how it works: each shingle has a sticky tar strip, and when it gets warm, this strip bonds with the shingle above it, making a tight, waterproof seal. However, for steeper slopes or when applied in winter, manufacturers often recommend hand-sealing.
Although asphalt shingles don’t have the self-healing abilities of other types of synthetic shingles, they do have some self-sealing properties. The adhesive strip enables them to bond with the shingle above, creating a waterproof seal and preventing them from blowing away in strong winds.
It’s important to follow all the manufacturer guidelines to ensure correct installation and maximize the effectiveness of these self-sealing properties. Proper installation is crucial to avoid issues like water leaks, which is the main cause of roof damage.
What Is The Best Way To Seal Shingles?
To ensure that your asphalt shingles seal properly, it’s crucial to use the right adhesives and follow proper installation steps. Here’s a guide to help you effectively seal the shingles:
#1. Choose the Right Adhesive
Opt for high-quality asphalt plastic cement or silicone adhesive. Avoid using too much of the product, as it can soften the shingle coating and cause issues.
#2. Apply Adhesive in Small Areas
Place a small amount, about a 1-inch circle, of adhesive under each tab of a 3-tab shingle or along the seams of laminated shingles. For hot melt adhesive, evenly space the spots along the shingle length.
#3. Consider Temperature and Sunlight
Asphalt shingles seal better when the temperature is between 70 to 80 degrees. In cold weather, sealing may take longer, while warm weather often shortens the sealing time.
#4. Follow the Manufacturer’s Instructions
Adhere to the sealing instructions provided by the shingle manufacturer, as different brands may have specific requirements.
#5. Ensure Proper Weather Conditions and Ventilation
Avoid installing shingles during rain to prevent water from interfering with the sealing process. Proper ventilation also helps prevent moisture buildup and aids in drying.
#6. Monitor the Sealing Process
Keep an eye on the sealing progress and promptly address any issues to ensure the shingles adhere correctly.
Factors Affect The Sealing Time Of Asphalt Shingles
Homeowners may have problems if their shingles are not adhering correctly. This is a major problem because it can cause water to leak into the roof, causing damage.
In this section, we will go over the different factors affecting the time to seal asphalt shingles:
The time it takes for asphalt shingles to seal is greatly affected by temperature. Shingles typically seal more quickly in warmer weather, usually in a matter of hours. On the other hand, the sealing process may take longer in colder weather, sometimes taking a full day or longer to finish.
The sealing time is also affected by humidity levels. Given that there is more moisture in the air during high humidity, asphalt shingles may not completely seal for a few days to a few weeks. While sealing may take less time in low-humidity settings, care must be taken to keep shingles from drying out too quickly, which could result in breaks or cracks.
Sunlight is another factor that has a huge impact on the sealing time. The process usually goes faster in direct sunlight because of the increased heat and UV rays. In contrast, because it takes longer for the shingles to heat up and the adhesive to activate, sealing may take longer in shaded areas. That is why it is better to install shingles when it’s dry and warm outside.
Depending on the type, brand, and other features of the asphalt shingles, the sealing time may change. Take into account the unique characteristics of the shingles used because it is important that you stick to the manufacturer’s installation instructions.
Why Is It Important To Get A High-Quality Coating For Asphalt Shingles To Seal Them?
To make your roof last longer, it’s crucial to pick the right coating for your asphalt shingles. A good-quality coating prevents the roof from drying out and getting brittle. It also acts as a protective layer against different weather conditions and stops water from seeping into your home. The right sealant not only reduces the need for repairs but also makes your home more energy-efficient by sealing any gaps in the roof. Just make sure to choose a coating that suits your local climate and the specific needs of your building.
Overall, the time it takes for asphalt shingles to seal depends on factors like temperature, humidity, and the type of shingle. To ensure effective sealing, use the right adhesive, follow installation guidelines, and monitor the process.
