A little background.
I‘m located in the Sonoran desert. Can be continually 115-16 in the summer with lows in the high 80’s Low 90’s for weeks on end.
Winter temps typically run low 30’s with highs in the high sixties. It’s also windy here. 45 mph winds aren’t that uncommon.
Not a lot of rain days, but not that uncommon to experience a couple of inches an hour when it does rain. At times a great deal more. I’ve had 4” of standing water in the yard delivered in very short order at times. On those occasions all you can do is really hope it is going to stop.
The manufactured home I live in has a roof design load of 20 lbs per square ft.
The house roof is ~33 x 76. The house was placed East/West. I/2 of the roof faces south. Ideal for a solar install.
I’d guess the roof is at a 2-1/2 or 3 in 12 pitch.
The 3 tab roof is at the end of it’s life. It is a 20 year roof that has needed annual maintenance (spot shingle replacement) since year 10.
The UV here combined with the low humidity is brutal on asphalt shingles, wood and plastics.
At the moment my plan is to replace it with architectural shingles (25 yr) and hopefully get another 20 with maintenance.
My questions are:
With only a 20lb per sq ft design load roof structure, is it a bad Idea to plan on placing the panels (36) on the roof after having the roof re-done with shingles that are ~50% heavier than the originals that came on the house. Do I need to find a different place to mount my panels?
If I intend to put put a bunch of panels up there, (36) on the south facing side, should I have a different type of roofing material installed on that side when the house is re roofed, or will the architectural shingles be fine. I ask because of the heavy rains that come yearly combined with the low pitch and multiple holes that will be made to mount the panel mounting hardware. If a different roofing system? What would that be?
Thanks,
Joe
