new here to the forum. after purchasing my first home 4 years ago, i’ve now come to grips with the idea that i do need a new roof. specs;
current roof - wood shingles (age - unknown). the shingles look pretty old and are slowly falling off my roof one by one.
size - i did some rough calculations and looks like its about 1700 sq ft (17 squares)
i recently bought some owens corning 30 yr oakridge shingles (got pretty good price $11/bundle).
now my question - when i go up to the attic, what i see are 4 inch wide by 1 inch thick slats. nailed on top of the slats are what looks to be the wood shingles. i.e, there doesn’t seem to be any wood sheathing between the attic and the wood shingles. is this normal? if i rip out the wood shingles and replace them with the OC shingles, i will have to buy new sheathing correct? haven’t checked on prices of sheating lately but from what i remember, they’re still ~$30 a sheet (4’x8’). thats gonna run me another $1500 for the sheathing.
