Hi, I have a 1991 Horton 14 x 66 with shingled A roof. My roof started leaking in October 2014. Due to no time to fix the problem myself i started calling roofers in Nov 2014. NOBODY had time to get to it and kept telling us call back in a month and they would see what they could do or either they would set something up and never show up. Well now here it is almost July 2015 and still the same thing. Now the roof is beyond leaking and the whole roof over the living room looks like it is going to fall in. I do have a past in patch roofing with shingles and new setup dw shingles and now have time to do it myself but it looks so bad i am worried i'm going to fall through the roof if i get on it. My question now since i rambled enough is 1) does anyone know the rafter sizing in the 1991 Horton A shingle roof? 2) what would i be looking at if i strip and go to a metal roof? Doing an inside out remodel anyway. New siding, new insulation, real ceder inside walls and so on so yeah just need to get this roof done first. Any help would be awesome! Thanks!!
