Putting this question out there,asphalt shingles are curling up,several are missing on house,need to put new roof on. Should I strip shingles as best as possible,then strap,or can I just strap over the existing shingles? Thanks in advance

If this is the first time you are redoing the roof you can put on the metal roof right on top of the shingles. The Amish do it around here all the time.
Just consider your roof framing/design and the additional weight of the metal. Strip the shingles if weight is a concern.
2016 - helped at afriend with a small operation, 300+ taps. = hooked
2017 - 20 taps @ home, 1 gal @ home on propane, then hauled to friends operation
Bought a whole shack locally, with a Leader 1/2 Pint, moved it home
2018 - 50 taps, 9 on 3/16 gravity and 41 pails -14 gallons of good sweet stuff
2019 - 27 taps, 17 on 3/16 gravity and 10 on pails - 12-3/4 gallons of good sweet stuff (most fun I've had with this hobby)
Part of that will depend on the pitch, Steel roofing sheds snow much better, but if the pitch is only 4/12 or 5/12 it may not do it quite as well. My sugarhouse is 6/12 pitch and snow rarely gets more than 6-8" deep before it slides off. My shop is a hip roof, the top is only 3.5/12 pitch, it holds snow much longer, the steeper angle o9n the lower roof (24/12) never holds more than 3-4 inches before it slides off.
By the way the pitch of a roof for those who may not know is stated as the " rise/ft, for example 4/12 rises 4" every 12.

Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
I have A steel Roof over asphalt Shingles. The house was like that when I bought it. It's not a huge Big Deal, that being Said most of the roofing guys I know recommend against it. I don't believe that its frowned on because they want the extra dough to strip the roof. It's a ****ty Job if you have ever done one.

I just had a metal roof installed on my log cabin over the shingles. Your adding very little weight because over the years your shingles have broken down and loss weight so you bascily hae no more weight than when shingles were installed years ago.
110 taps W.F Mason 2x3 and two turkey friers for finishing
2011 expanding to a Mason 2x4 with a blower increasing taps to about 200
2011 Hurricane Irene rips thru my small sugar bush cost me to lose 20% of taps
2014 I have reworked my lines for 2014
32 taps on 5/16 line with check valves
57 taps on 3/16 line with check valves
55 buckets with total tapped trees of 144
The color of painted roofing installed on slats over shingles will fade due to heat build up -- that's why the roofers recommend against it.

Just put steel on my house last year and did it right over the shingles. I laid 1/4" fanfold insulation over the shingles and secured with plastic cap nails. Steel over that. I can see that there might be pros and cons to both options, but for me, not having to tear off, haul, and pay to dispose of the shingles made leaving them a no-brainer.

Went off the deep end. Might be in over my head...
Metal roofing over shingles isn't a problem as long as the roof can take the additional load (not likely a problem). You may need to trim some of the shingles if they are curled/cupped really badly, otherwise just fasten down some strapping and use long screws to go through the metal/strapping/shingles/decking and get well into the roof rafters. If you're paying to get it done, the main difference is cost. Removing shingles is a pain in the butt and generates a good deal of waste material to be disposed of. Contractors charge accordingly.

You might want to check the steel manufacturers warranty. With some companies it voids the warranty if installed over shingles.
