How To Add A Roof Coating To Shingles

Posted on

The asphalt shingles on your roof are constantly exposed to damaging rain, hail and sunlight. All of this tends to make them brittle and crack prone. Any cracks in your shingle roof will increase the chance of your roof developing leaks. In order to protect your roof shingles from this damage, it's important to regularly apply a coating to the surface. In addition to sealing your roof and protecting your home, these coatings also give you the opportunity to change your roof's color (if you wish).

What You Will Need

  • Protective Gloves

  • Protective Eyewear

  • Nonslip Footwear

  • Extension Ladder

  • Stiff Bristled Broom

  • Roof Coating Material (Water-Based)

  • 5 Gallon Bucket

  • Paint Stick

  • Paint Grid

  • Four-Inch Wide Paintbrush

  • Roller Brush with Handle and Extension

Step 1. Position your extension ladder against the side of your house. Make sure it is on firm footing and perfectly level. The top of the ladder needs to extend at least 3 feet beyond the edge of the roof.

Step 2. Put on nonslip footwear, protective eyewear and protective gloves. Climb the ladder, taking your broom with you. Use the broom to sweep the surface of the roof clean of any dirt or debris. Climb back down the ladder and then bring up the other materials you need.

Step 3. Open the roof coating and use a paint stick to stir it thoroughly. If the coating you are using seems thicker than regular paint, add a little water to it and stir in the water to thin out the coating. You want to have the same consistency as latex paint.

Step 4. Pour the roof coating into a 5 gallon bucket and then lay the paint grid into the bucket.

Step 5. With a paintbrush, apply roof coating to any parts of the roof you know you won't be able to reach easily with the paint roller. You should also use the paintbrush where the roof comes into contact with siding or other features.

Step 6. Assemble the roller brush and slide the brush down over the paint grid in the bucket to load the roller with the coating.

Step 7. Go to the peak of the roof and (at one end) begin to apply the coating in a thin, even layer across the surface of the shingles. The best way to do this is to use the brush to create a large W shape (approximately 3 feet across) and to then spread the excess coating around. Continue doing this as you work your way from one end of the roof peak to the other. Then start one level down from this and go back in the other direction. Try to make sure that you finish where your ladder is.
