How to Seal Over Asphalt Shingles
Asphalt shingles are used on 80 to 85 percent of all residential roofs. Because of this, there is a large segment of the population who would have an interest in sealants for asphalt shingles. Adding a sealant to asphalt shingles extends the life of the roof, which saves money for the homeowner. Although you can apply a sealant yourself using a sprayer or roller, if you are unsure of your capabilities, it is best to hire a professional for the job to avoid injury from falling off of the roof.
Inspect the roof for any damaged shingles, and then repair or replace them before applying sealant to the roof.
Spray an even coat of liquid sealer over the entire roof, using a professional pressurized sprayer. Allow the shingles to dry for a couple of hours. Although you can use a full-nap paint roller to do the job as well, a professional sprayer is much more efficient.
Complete the job by spraying a second coat of sealer evenly over the roof.
Things You Will Need
- Liquid roof sealer
- Spray applicator
- Check your local weather forecast before starting this project, to avoid application before rain. Keep roofing nails, extra asphalt shingles and a hammer on hand in case some shingles need to be replaced or secured.
- Because this job must be performed in a standing position on the roof, it is recommended that a professional be hired for this type of work because of the high potential for serious injury.
