Plywood or chipboard for shed roof.

Since this is my first attempt at carpentry i was unaware to just how heavy and awkward it would be to manouver these sheets though i soon found out. Due to requiring extra tools for cutting the sheets to size the roofing job for the shed hasn t been completed. Could it be that these people have inadvertently used the wrong grade of material. Plywood with similar properties currently costs about 30 more for an equivalent thickness.

However there are some sceptics out there who doubt the strength and durability of osb. It can withstand moisture for a brief period of time but may become warped and delaminated with consistent exposure to the elements. The lower the slope the more weight for snow load but less wind force. Cdx plywood is a construction grade type of plywood that is designed for exposure to the elements.

More product details close. If you are sticking with the original sheathing or boards if that s what it had i d suggest adding a vapour permeable membrane over top as an air barrier. Up until 2000 plywood held the majority of the market for wall roof and floor sheathing when it was surpassed by osb which as of 2018 held about 75 of the market share. Osb is okay but plywood handles moisture a bit better.

One of the nice things about plywood is the variety of options you can buy. Even though plywood is more expensive and osb stronger my recommendation for a shed roof is 5 8 or 3 4 construction grade exterior rated cdx t g plywood. If you do add new plywood sheathing you could just tape the joints and it will act as your air barrier. Most construction sites will consider the use of either osb or plywood for the roof.

Plywood sheathing delivers outstanding rigidity strength and versatility and is an excellent choice for light frame wall and roof assemblies in weather protected applications. Plywood is made with an odd number of layers for optimal strength and performance. The higher the slope the more quickly the snow and rain will be shed but also the greater the wind force. Using oriented strand board is a tested way of reducing costs for building your shed.
