While it may seem counterintuitive to apply a reflective roof coating at the end of summer, it is actually a good time to do so. Ultraviolet rays from the sun degrade your roof tiles all year long, not just during the heat of summer.
In addition, reflective coating may also seal slight cracks in your roof, which can prevent water from entering your roof and freezing during winter's chill. Freezing will cause the water to expand and create an even larger hole or crevice for water to enter.
Finally, the cool temperatures of autumn allow you to work in relative comfort.
Convinced? You can begin by purchasing the necessary materials.
What you will need:
Although the most common colors are aluminum silver or bright white, you can find reflective coatings in various light colors. You will need to measure the length and width of your roof to determine the square footage (length multiplied by width) to determine the amount of coating you will need.
The coverage area will be listed on the outer label of the cans of coating. Reflective coating is usually sold in one- and five-gallon cans. While it is cheaper to buy a five-gallon can, it is heavy to haul to the roof and to move across the roof as you apply the coating, so you may choose to buy individual gallon cans for easier handling.
Applicator brush and handle
The best way to apply reflective roof coating is with a hard-bristled applicator brush. The brush head, along with the twist-on handle, is usually sold in the same department as the reflective coating.
Gloves, hat, sunglasses
The adhesive quality of the coating is a double-edged sword, because while it allows the coating to stick well to the roof surface, it also sticks to anything else it touches. This includes your skin, clothes, ladder, shoes, and tools. Remove your gloves when you are not working with the coating, and avoid touching anything but the brush and roof while you are applying the coating.
The reflective nature of the coating requires the use of sunglasses and a hat to protect your eyes and skin from the sun. Don't be deceived by the cooler autumn weather, because the ultraviolet rays can cause damage at any time of year, especially when reflected from all sides.
Applying the reflective coating
You must first sweep the roof thoroughly to remove as much dust and debris as possible. Don't sweep it into your rain gutters, or you will cause them to become filled and clogged, and you will face the unpleasant task of cleaning them.
After the roof is cleaned, begin to apply the coating as far away from the access point to the roof as possible. You will want to end the task at the ladder and avoid walking across the coating.
Try to pick a time of day when the sun is at your back. This will provide additional protection from the reflected rays of the sun.
Remember to remove your gloves before climbing down the ladder and to check the bottom of your shoes before walking into the house. You will be surprised at how much coating you have accumulated and spread if you are not mindful while you are working with it.
