Asphalt shingles made in recent decades include less asp[halt than they once did, so they're drying out and failing faster than ever before. They contain small sand-like pebbles that stick together when their natural oils are intact. But once those oils start drying out with age, you may see the granules flaking off in your gutters or downspouts. You might also notice black stains and streaks or shingles cracking, breaking and curling
Don't wait until your shingles are too old and you have to replace them. Rejuvenate them now for a fraction of the cost of a new roof!
