Osb vs plywood for roofing.

You won t have to worry about the material expanding anytime soon like when you use osb. Lipinskiy says that both plywood and osb are sufficient but that he does prefer osb. There is nothing wrong with plywood but for me personally we always go with the osb he says. You can consider this as an advantage but it can also have some drawbacks.

While a sheet of plywood might be 5 to 7 plies thick a sheet of osb is made from as many as 50 strand layers packed and compressed into the same thickness. Screwe holding ability is a critical matter in roofing. Despite its common use as such we don t recommend using osb for subfloors but that s really just for aesthetic reasons. The reason is very very simple.

Osb is made by combining glue resin and wood chips and pressing them into the shape of a plywood sheet then baking everything together. This is why plywood is considered as the better option for roofing. When the roofing material cannot hold nails and screws properly of course they cannot hold its shape very well. Plywood is the ideal material for places having a wet weather condition.

As a homeowner if you find yourself in this position know that when you install a new decking system you will have to decide between using plywood or osb. This is why you need to know the screw holding ability between plywood vs osb for roofing. Osb vs plywood screw holding. Osb boasts a more consistent density.

Plywood is better than osb for subfloors. Because of this manufacturing process osb is at least half the cost of cdx plywood. Compared to cdx oriented strand board osb is made very differently. New homes will usually see a few rainfalls before a roof is on and as noted above osb doesn t handle moisture well.
