How soon will a new roof show aging?
When a new roof is installed research indicates that aging begins soon after. Initially, aging is rapid during the curing phase of the life cycle. During this stage, granule loss may occur, small blisters may develop or the shingles may curl slightly at their edges. You may even notice that this curling is more pronounced during cold weather and the shingles lie flat as temperatures rise. The good news, however is that after the curing stage the shingles enter a long period of slow aging, which lasts for the major portion of the shingles’ natural life.
