To get an idea of added value, you would need to contact a good Realtor in your area. They can run comps for recent sales in the neighborhood to see what value is added by a metal roof as opposed to a shingle roof. If the Realtor doesn't know how to do this metric, find one that does.....

Once you install the standing seam roof, you'll never have to redo the roof again. That's not the case with the shingle roof.

I owned a home for 30 years that needed one partial and one full reshingling. It also collected debris and required periodic maintenance a couple of times a year. And when I sold it, the state of the roof was such that I had to provide an allowance to the buyer for some re-shingling. I moved to a new home with a standing seam metal roof 13 years ago. I have never needed to do maintenance on it and it will likely outlast me.

You may not be guaranteed a specific financial return on a standing seam metal roof, but the advantages in terms of not having to deal with a shingled roof and the easier time you may have selling the house in the future are not insignificant considerations.

a few thoughts:

a metal roof is less likely to catch on fire from blowing embers... not nothing in Napa... if the roof doesnt show from the street or driveway, the aesthetics are lost...a metal roof can be really quite... loud.... in the rain.. if you are planning to have cathedral type ceilings.

Homeowner's perspective- YES, it is worth it. I have standing seam Gavalume with a 50 year + warranty. No maintenance, aside from a bit of gentle wash, every once in a while. Looks amazing, and you can get every color under the sun, even if it isn't Gavalume.

Check in with a Realtor, sure, but also your insurance agent. That, plus my integral stucco and fireproof siding saved me a ton on insurance $.

In a resale, I can't speak to your market. But this is one of those things that in my market (Austin Texas) means a lot to people who don't want the maintenance costs.

I don't hear the roof at all in rains. I do hear the Galvalume gutters/downspouts a bit. But it is gentle.

I live in the Pacific NW so we get steady rain for many months in a row. I have cathedral ceilings in some rooms and I don't find my metal roof to be particularly noisy. The sound the rain makes is actually quite nice....

i guess it must depend on the pitch of the roof. the flatter, the splatter!

We put a standing seam metal roof on a large farmhouse-style new build in metro Atlanta, where it is somewhat rare, and while I can't say it increased the value (no data for that really, there aren't good comps for our home for other reasons), it did sell at 98% of asking price the first week. I have loved it...our home has been extremely energy efficient and on a hot sunny day when the roof is so bright it glows I like to think about all the heat it's reflecting!

I'm not sure this will be meaningful for your house, but the one thing I wish I'd known for ours is that the gutters available (half round to match the roof) have been a pita to get right. My husband loves the roof and hates the gutters. I could go on and on, but suffice to say we have consulted at least 3-4 specialists with no fixes. But, our house is a two story on a daylight basement with a much steeper roof line that I'd imagine yours is on a CA ranch. We were told the steeper pitch causes the water to run fast, and the lengths required (up to 50') are super difficult to tilt effectively. Also, the house sits under a gorgeous 150+ yr beech tree so there is a lot of gutter cleaning going on around here. And we couldn't find gutter guards for the half-round gutters. Again, I hope this is all moot for you, but in GA where it can get very rainy we wish we'd had a more effective gutter system from the get-go.

We are reroofing next year and going for a metal roof this time, I happen to love the sound of therain on a metal roof. We have a 50s ranch with quite a low pitched roof.

patricia, i will give you a heads up that rain on a metal roof *can* in fact be very loud and not soothing at all. if you have been at someone's house and it was soothing, i have to have you consider: how hard was it raining, and what was their roof pitch, and how sound insulated was their space... was it a cathedral ceiling, or was it a flat ceiling.

i say all this (several times, dont mean to belabor the point) because i spent a rainy weekend in maine with friends and you could not hear to talk in some rooms of their house. it wasnt stormy... just rain... and it was not cozy, it was intrusive.

I don't remember the sound of rain on the metal roof of our place in the Adirondacs. What I do remember hearing is the frantic scritching of tiny squirrel claws as they lost traction and slid down the roof.

If you have some intention in the future of collecting rain water in a cistern for supplemental water for your homesite, then a metal roof makes a lot of sense.

This is a home in Napa above. I love the natural finish on the roof.

Here's another light home with a more natural finish on the roof.

Hi Beverly thanks for your perspective and the pics. These are all lovely

You really should look at Firewise. Ruidoso/Lincoln Country, NM requires metal roofs due to the high fire danger.

In Napa, I believe if we are class A rated we are good.
