Typically, sealcoating is for roads and asphalt-covered driveways. It is a liquid protectant coating that prevents and slows rapid deterioration of the binder used in asphalt. However, because sealcoating is also waterproof, it can be used in other ways. In this particular example, sealcoating can be used on asphalt shingles. Here is how to apply it, as well as the benefits and reasons for doing so.
How to Apply Sealcoating to an Asphalt-Shingled Roof
Most shingles are made of asphalt to begin with. That means that sealants made for asphalt may also be used on roofs, with a few exceptions. To apply sealcoating to your roof, you can either hire a roofing contractor or a paving contractor to climb up there to do the job or do it yourself.
Follow these directions to do it yourself:
- Pressure-clean the roof gently.
- Choose your method of application: spray, brush, or squeegee. Unless you are certain that you can control the downward flow of the sealcoating easily enough with a brush, you may want to spray or squeegee instead. Spraying is the easiest-to-control option.
- Climb to the top of your roof, and apply the sealcoating in sections from the peak to the gutter. Keep doing two- or three-foot-wide sections of the roof until you have coated the entire roof.
- If you have chosen to spray on the sealcoating, a second layer is recommended to make sure the entire roof is adequately protected.
- Make sure this project is completed on a dry, warm day so that the sealcoating cannot be washed away or freeze and crack.
The result should be a very black, glossy-looking roof that repels rain.
Reasons and Benefits of Sealcoating Your Roof
Small roofing repairs are not small in expense. Simple patch solutions cost less and are actually extremely effective. Sealcoating is one such patch solution that is not only effective but also durable and long-lasting. The affordability of supplies also makes it a favorable option in comparison to other roof patching solutions.
This coating waterproofs your roof. If you are experiencing any sort of leaks, the sealcoating stops them. On a roof, this coating can last anywhere from a year to five years, depending on the quality of product you use. That means that sealcoating the roof can postpone any roof repairs until you can afford them. Since it is waterproofing your roof, it also prevents water damage, mold, and mildew from leaks.
