Are little patches of OSB allowed by code to be used to repair a Roof deck?
Maureen

i hired a roofer to repair holes cut in the wrong places in my roof by the previous roofer. He is using small pieces of OSB, about 9" by 18" to patch the holes. I told him I understood that any patch must span at least 3 roof rafters. I told him not to proceed to put new roofing on my house until the roof decking is properly repaired. He did not follow my instructions and instead put my brand new roof right over the tiny patches he inserted. When I came home from work on a rainy day and saw him doing this I told him to leave my property. Now he refuses to finish the roof. He took away all the bundles of shingles not yet used and took away all the remaining materials and told me he would not return.

What do I do now? My roof is only half completed and there is new roofing over the patches that I do not believe are properly repaired.
Does the International Residential Code (IRC) 2018 require patches to be of a minimum size? Can anyone give me a recommendation? Or tell me what you would do?  I do not have any relatives to go to for help and our municipal inspectors have been passing every roof without looking at the roof. They do not provide help. What can I do? 4 days of rain are forecast and I am very worried.
Thank you for any help you can give.

Maureen,

They can be re-enforced from inside. In fact, that would be the only way they can now be patched. Unless you want a hump in your roof. Which I know that you don't. I would tell the contractor to ensure they span the new plywood across rafters, or span it rafter to rafter and then place a sister along side of the original rafters. This will give is extra strength. I would also use 2 pieces of three quarter plywood as the weight bearing patch, plus an exact piece to fit into the hole from the inside. Glued to the inside of the sheeting, and then use the sisters to hold the weight. a single piece would make it too soft if someone were to step on it. this will level the roof line sheeting and give support when someone steps on that area. Do not use nails/screws up toward the shingles.

You are the boss. You tell them what to do. You do not allow them to tell you. Do the work the way you want it done, or pack up and leave. Create a written contract of exactly what you want. This is the only thing that you will have if they do something else that is wrong, or not up to your standards

Thank you Andy, but I put a new roof on to sell the house and I do not want a mess of patches made in my attic. As I said, the roof is not finished. I told him to leave my property when I saw he had roofed over those tiny patches. I want my house to look good inside and out and I expect my roof to be done to at least minimally meet the standards of the International Residential Code.

Would there be some reason why you would not expect him to tear off the roof he placed over the patches (which will mean removing a few rows) and replace the OSB decking with proper material?

Maureen,

No, no reason at all. And what you are asking is within your right to have the job done correctly. I did know that you were selling the house. Maybe contact the Better Business Bureau, or equilivent source. I am not sure where you are located, but I'm sure there is something like that if you are not in the United States. Have you contacted the company that you hired? Do you have a contract with them? Patches are allowed as long as they are safe and secure. But I can see your point. I would want it done right and exactly the way I specify.
