the rain gutters are a one shot assembly with a large spot welder......Roof section window frame and gutter. Would be very hard to salvage a used one.

Carefully cut off the old one.

And have a sheet metal shop do you a couple of sections and mig weld inplace with drilled holes in the new section 1/4 inch and do a rosette weld that you can sand down.

When you do the grinding of the welds on your roof watch for heat build up that can cause warping.......we orefer trhe course flap wheel to a disk...... leave the little pinholes you find and fill them with a then coat of JB weld..... works well on clean metal and can be sanded flush.

We use it at the barn and prefer it to glazing compound
