Sorbent pads are great for protecting roof shingles from ChimneySaver overspray. When spraying ChimneySaver through a pump-up sprayer, overspray that is allowed to dry on the roof can discolor shingles making dark spots appear where overspray lands. This soft, absorbant material prevents overspray from soaking through as well as being designed to stick to the roof without sliding off. Sorbent Pads are available in packs of 6. Don't forget these when doing your next ChimneySaver job.
