Roof sheathing

[my250r11]

It is my job to write the correction. It is not for me to decide who pays what. The issue shall be corrected before I will sign off.

If I worried about cost I would never write a correction. Every contractor & or homeowner this will cost me $XXX is the first thing out of their mouth.

That is why I have a "code" compliant & match "existing materials" replacement ryder on my 1905' Craftsman fire insurance policy.
Also upgraded as to contents. Again, buyer beware of for what and why you buy your policy.

Recently had hail damage to my asphalt shingles. The roofer has been tearing the old roof off and has found that the sheathing is dimensional lumber. Mostly 1x6's. He says it all has to be torn off and replaced with plywood. He says it is not up to code and he has no choice. At my expense of course. Any feedback would be appreciated.

It sounds like you’re dealing with a challenging situation. It's common for older homes to have sheathing made from dimensional lumber, like 1x6 boards. While these boards can sometimes be acceptable, building codes have evolved, and many areas now require plywood or OSB (oriented strand board) for roof sheathing due to its strength and uniformity.

There is no argument for this. Your situation is not a code issue unless the shingle manufacturer installation requirements prohibit this.

I sheathed my roof with 1" boards. Perfectly acceptable to (Canadian) Codes, and also the (American) shingle manufacturer.
