Pat _ I also saw a statistic on X % of roofs were replaced for cosmetic reasons ( as opposed to leakage/failure), but danged if I can find those numbers again. I saw it posted on a washing forum somewhere and meant to bookmark it. However I didn't and can't find the info now.

Yes, i've seen a statistic that said 50% of roof replacements are due to appearance. Can't remember where though. Based on what my customers have said the main reason they have it done is for appearance and curb appeal purposes. Second reason would be extending the life of the roof. However, there are numerous benefits!
