Shingles Over Torch Down?

When a roofing guy does a modified torch down system....does he still put shingles on top of that?

No. The modified is the roofing material. It is used for low pitch roofs where shingles would not work.

Thanks....just confirming.....after I wrote the post I realized that nailing on shingle through that nice new torched down roof would not be a good idea....

Is modified torch down also used for low pitched hog valleys, where the bottom point contains a valley flashing? And in this torch down case, the modified itself replaces the shingles plus valley flashing?

One roofer suggested that for reroof bid where the rest of my roof would have shingles.

Other roofers didn't suggest that, so they would still continue with shingles it appears.

Daluu,
not sure what you mean by a hog valley. Modified roofing is a material that comes in a roll and the torch heats up the backside to adhere it to the roof. I don't see any advantage to putting shingles in low pitch applications, in fact I see it as a leak waiting to happen. My younger brother is a commercial roofer, union actually, for the last 30 years. He has forgotten more than I know about the low pitch roofs. I will ask him and let you know what he says.
