The reality is that all shingles, whether organic or fiberglass, are likely to last only 60 to 70 percent of the warranty period. Because all the warranties are pro-rated in favour of the earlier years, the length of the warranty becomes largely insignificant. Both wood and metal roofing have longer life expectancies and more closely match the warranty period.
