Metal Roofing?

I had my roof done just over 2 years ago. I picked the architectural/laminated GAF shingles. Total came to about 18 grand, it`s a big place. The old style 3 tab shingles were far less high wind resistant, I`d lost a bunch. I asked about a metal roof, it would have been close to 40 grand, I laughed when the company owner said "metal roofs are for barns". Maybe in my 20`s or 30`s I`d have have considered it, not in my late 60`s. And who the hell in their 20`s has 40G`s for a roof? To the OP, where are you located? I`ll recommend my roofer, 2nd generation family biz.

Few people in cities stay that long in one house and the future value is questionable. The ROI of almost every renovation / upgrade is negative.

Young buyers move up. Older folks move to the cottage or condo when the nest is empty. The 50 year window doesn't cover a lot.

How long does a thatch roof typically last? Are you required to replace it with another thatched roof if it has a historical designation? I saw a tv show years ago about a couple that were restoring a home in the UK that was built in the 1500’s. They had to replace an oak beam that had been eaten by beetles ( no,not those“Beatles”). The building inspector made them replace it with another oak beam and would accept nothing else. Apparently oak trees that big don’t exist in the UK anymore, they had to have one shipped from Canada at huge expense.

When King Charles was a prince he grew organic thatch which was expensive but lasted longer.

When the owner built that oak-beamed house five hundred years ago he was supposed to plant an oak tree in the back yard. If he had done that he'd have the new beam. There's some online tale about that at a university in the UK.

I would still strip the existing asphalt. Low cost relative to entire project. Shows you didn't cheap out. Allows you to inspect the deck prior installing a lifetime roof. Steel should be more resistant to hail when installed on wood directly (my guess, I haven't looked for documentation on this). Asphalt under steel will get smoking hot and continue to degrade over time. Removes many thousands of pounds off your house. That has to be a good thing.

235 pound shingle = 235 pounds per square, 100 SF. My roof had about two tons of shingles on it. I wasn't worried about putting on the second layer in 1985 but, against my better judgement, helped my step father put a third layer of asphalt over a layer of cedars. I think the nails were 2-1/2".

My shingles were ~11,000 lbs when new.

On a slightly related note, a roof collapsed on a house in Oro. The seniors inside were unharmed but apparently may not have been entirely aware that it happened. Sad situation. House is farked. Window/door openings have racked. Probably a tear-down. Steel roof would have had avalanche risk but it's probably impossible to build enough weight to collapse.
