TAKE THE SHINGLES OFF FIRST IF NOT STUCK TO THE FELT THEN RIO OFF FELT I BEEN ROOFING 35 YEARS SOME ARE TOUGH I TORE OFF 9 LAYERS ON ONE HOUSE ABOUT TO FALL IN TO MUCH WEIGHT.
I just got quoted 45k for a shingle roof for my house. I went to a roofing supplier and 50 year GAF material (2900 sqft, 30 squares) is $9500. Includes material delivery and makita nail gun! It'll be fun
Considering how much work is involved in roof replacements I am suprised people go with asphalt shingles instead of somthing longer lasting. This is not somthing I would want to do more than once in my life.
You have more experience than I do for sure but I recommend wearing long sleeve shirts and pants. Don’t forget the hat. Protect yourself from the sun and the sun doesn’t drain you as much
