With the exception of the Master Flash and Retro-Master Flash, all flashings have a one year warranty from the date of manufacture. Flashings cannot be guaranteed for the life of the roof due to varying roof life spans, and potential adverse conditions (i.e. extreme heat, extreme cold, hail). If a roof is replaced the flashing should be replaced at the same time. Master Flash and Retro-Master Flash are the only exceptions; if installed properly according to industry standards, they have a 20 year warranty from date of manufacture.
