Am looking to replace the (hip) roof on my 1957 single story brick ranch. Not sure how many squares, but probably about 25-30. Roof deck is tongue in groove pine on about a 5.5 pitch. Currently a turbine vent with one small stretch of ridge vent.
Lots of research on the internet and drove the neighborhood to see what other HOs are doing (mostly 3 tabs being replaced by archs). One neighbor had a metal roof that had a shingle appearance. Really liked the look, and he told me it was the Classic Metal Oxford Shake. Contacted the co. who put it on for him (they are an out-of state operation) as well as the mfr, who gave me another out-of-town (but in state) group. Both had the same process- self stick underlayment over the old 3 tabs (roof is not currently leaking) then cover over with the metal roofing, which is an interlocking panel system that just looks like shingles. Both kicked back at the idea of a complete tear-off and installation, and told me that the old shingles were “Insulation”, etc. Frankly, it all sounded like bs explanations pulled from nether regions to me, but I’m very much not an expert, so maybe I’m maligning them unjustly.
I have always been under the impression that the way to do a roof “right” was a complete tear off to expose any hidden problems, and it seems counterintuitive to me to put a new, long-lasting product over something that will continue to deteriorate through the years. I am also a little concerned about the underlayment over the old shingles creating a long term moisture problem in this high humidity environment. I have since read that aluminum roofing is a problem in salt-water exposed areas. My house has no direct salt spray, but is about a mile from brackish river/salt marsh. The old (40+ years) aluminum windows show mild to moderate corrosion. Nothing awful, but they are under an 18" overhang.
I really like the idea of a metal roof for superior heat reflectance and wind resistance, along with not having to re-shingle in 20 years, and am not averse to spending the additional $$ as I believe it will pay off in the long run if I can get a quality product/job. But standing seam (which is what the local guys do) is not the right look for this house. I’ve already rejected the out of state co. due to a BBB check, and can’t get a price out of the in-state out of town guys. I have also looked into a product called Reinke shakes, a corrugated aluminum shingle manufactured in Nebraska. But it has to be hand nailed, and interlayered with 3 layers of felt, like old wood shakes. The one local contractor I talked to about installing them spent literally 3 hours coming up with reasons to hate them. He normally does historic slate roofs and I tried him because of his familiarity with traditional techniques.
So, 1) Am I crazy to be pursuing the metal option and should I just give up and get 30-40 year architecturals?
Am I right to be concerned about metal and 100% ice and water shield over the old shingles?
What about the aluminum/salt water issue?
Does anybody have any experience with Reinke shakes or do you have any alternative products to suggest that would give metal protection and reflectivity but still look like individual shingles. Or I should say, be an appropriate look for my house.
Thanks for your patience with the long post. I’ve tried to give details, but apologies in advance if I’ve violated etiquette with my wordiness!
