The roof of your home is the protective shield that shelters your house from the outside world. When your roof is leaking, this protection is severely diminished. When this happens, you will be searching for an effective solution that does not damage your roof further and won’t cost a small fortune– that’s where Flex Seal comes in.
It is safe to seal a roof with Flex Seal. Flex Seal is applied to damaged roofs to fill gaps and prevent leaks. It forms a solid bond to the shingles, tiles, or metal on your roof that keeps water out. Also, Flex Seal can form a protective seal for years to come without harming the roofing.
Keep reading to learn more in detail about how you can use Flex Seal to cover holes and cracks in your roof. I will explore how long you can expect your Flex Seal to last and how you can avoid some issues that people often encounter when using Flex Seal on roofs.
Will Flex Seal Stop Roof Leaks?
A leaky roof is always a cause of concern in any property. A leaky roof can allow water to pass through into your home, which can devastate structures, walls, ceilings, and possessions. As a result, people often look for an affordable and effective way of stopping leaks in a roof without paying for a replacement.
Flex Seal will stop roof leaks. You can apply Flex Seal as a thick layer over the damaged section of your roof where the leak originates. The sealant fills in all cracks and gaps then hardens to form a water-tight rubber seal over the damaged areas, stopping roof leaks.
Flex Seal is a durable and practical material. The seal formed by Flex Seal is an excellent barrier that does not allow any air or water to pass through. As a result, it is an ideal product for sealing roofs and repairing leaks.
You should apply Flex Seal to the source of the leak in the roof for best results. Doing so ensures that you have protection against water and the elements. If the Flex Seal does not cover the root of the issue, the leak will likely continue causing further damages to your roof and home.
You can also use Flex Seal as a preventative measure to protect your roof from leaks and water damage. Some people apply a layer of Flex Seal to roofing before a storm or bad weather. Doing so offers your home added protection that prevents storm damages and keeps your home dry, even during severe weather.
How Long Does Flex Seal Last on a Roof?
Flex Seal is safe to use to form a protective seal over many surfaces, including roofing. However, the roof of your home experiences harsh conditions like sunlight, wind, and rain that can cause harm to some materials.
So, how long will Flex Seal last when exposed to extreme conditions on your roof?
Flex Seal lasts for up to 30 years on a roof. Flex Seal will last for different amounts of time depending on the local climate and maintenance. As a result, Flex Seal can be used to repair leaks and cracks on a roof that lasts for years.
Several factors can cause Flex Seal to last longer.
For instance, applying multiple thick layers of Flex Seal will form a stronger bond on your roof. Using plenty of this sealant will reduce the rate of wear in the Flex Seal and ensure that your roof remains protected for decades to come.
While Flex Seal can last for up to 30 years in ideal conditions, it’s unlikely that it will stay in good condition that long on your roof.
Flex Seal is considered a short-term fix for roofing issues, and after applying Flex Seal, you will likely need to hire a professional roofer to carry out more extensive repairs.
Will Flex Seal Form a Strong Bond if It Gets Wet?
Flex Seal is a great option when your roof has been damaged and needs a quick repair. However, roofs typically wear down and crack during bad weather like heavy rain and storms. As a result, you may be wondering whether Flex Seal can still form a strong bond if it gets wet on your roof while drying?
Here is a useful video that shows how Flex Seal can be used to repair shingle damage after a storm:
Flex Seal will still form a strong bond if it gets wet before it cures. However, some sprays will run off with the water if you apply them during heavy rain or snow. As a result, it’s best to use Flex Seal at least 24 hours before any heavy rainfall.
Flex Seal takes between 24 and 48 hours to cure and dry out thoroughly. It will dry slower on a wet surface, but it will still dry.
The thickness of the layer applied to the surface will also influence curing time, with thicker layers taking longer to harden. On top of this, Flex Seal typically dries quicker in humid climates and when placed in direct sunlight.
If you wish to apply multiple layers of Flex Seal for added protection, you will need to wait at least 24 hours after the initial application to add a second layer.
It’s best to let the initial layer of Flex Seal cure entirely before applying a second layer. If the Flex Seal is soft to the touch and easily malleable, the coat has not cured, and you should wait before applying the second layer.
Flex Seal is an ideal product for use on roofs. Flex Seal is usually applied as a liquid onto a surface. Over time, the material cures and forms an airtight and water-tight seal. This protective barrier on your roof can prevent leaks and keep the elements out of your home.
Flex Seal can be applied to wet or dry surfaces and still form an adequate bond. However, Flex Seal will dry quicker when applied to a dry area in humid conditions. Nevertheless, the curing process for Flex Seal is 24 to 28 hours.
