| While I know some OSB is labeled as to a 'side up', by the nature of the product, there really should not be any major difference in strength and performance of your subfloor. Typically, the difference is surface preparation, which is more important on sloped surfaces such as roof. I can assure you this is not the first time this has happened on a jobsite. I doubt that any type of corrective measures should be necessary. |

| If your inspector thinks it is a problem (even though it isn't), just install another layer of subfloor right side up. You dont want to mess with ripping up glues subfloor. |

The wrong side up on the OSB should not be a problem for the inspector. If it is, then call the OSB manufacturer and ask them for a letter saying that it does not matter which side is up. A reasonable inspector will accept the manufacturer's word on an item that does not involve safety.
Inspectors have required me to remove Glulam beams installed upside down but that was because of the camber (bow). OSB does not have camber. |

| Call and speak to the head of the inspection dept and explain. I'll bet he says no problem. If not ask what to do. Amazing how helpfull they can be when you ask for help BEFORE they fail something. Good luck! |

| I believe it is better for you to decide what you are comfortable with and NOT ask the inspector or bring it up, if you are all right with it. |

| Any time I have a situation where I do not know how the building inspector will respond, I simply call the chief and ask them my questions. I have never had one to ask my name or where my project was located. My point is that it is far better to know the inspector's position on the matter than to worry about it. |

One thing to watch for is if your project won't be completed rapidly, (like if your building for yourself and the project may drag on for more than a contracted builder might take), is delamination of the surface chips. Often, depending on manufacturer, the bottom side does not receive a protective wax surfacing. Foot traffic and weather could cause a roughening and even swelling of the surface before you have a chance to get your finish floor down--leading to issues such as trouble installing tig flooring, release of adhesives if using laminates or none floating linoleums, lack of bonding in gypcrete/subradiant installs, etc.
Being a cabin builder whose projects can be exposed to longer than normal times in the elements I quickly switched to Advantech when it became available -- I had one project delayed by redesign after the main floor system was already lain and had it had to over winter exposed. Once back on site in March it looked the same as the day we put it down in Sept. and tig flooring went down without a hitch. And I don't own stock in GP, I just grudgingly plug Advantech.
And always call the inspector rather than dealing with it on site, they want you to get your project finished so they can start taxing you!!!!!
Cheers--Chris

Carl,
On one of my projects we simply went to the paint store and bought returned latex paint at a very low price. One person poured latex paint from the bucket as another person used a large roller to spread the paint over the OSB sub floor. We painted the subfloor since we used regular OSB and we knew we were in for a few days of rainy weather. After doing this we did not have any trouble with the OSB. The code official did not mention the painted subfloor. I bet it was the first subfloor that he saw painted.
Now I am not saying that you should paint the floor to hide the mistake. I still think it would be simpler to ask the code official whether it mattered which side was up. Now if I was worried about rain ruining the OSB then I would consider painting it.
After you get your problem resolved let us know how it went. |

This is not a problem and I doubt it very much that the building inspector will even notice. Even if he does it isn't a matter of strength, as one reply stated more of a protective coating than enything else. Not a big deal and definetly not worth rippping up and replacing.
