How to lay plywood on a roof.

It is assumed here that you will be applying plywood particle board or wafer board sheathing. During a hurricane the strength of the sheathing on the roof can greatly impact the homes ability to weather the storm. This video shows how some roofs fail under heavy winds in uplift situations. Run a string line over the roof trusses and then either plane the high parts or add packing to create that perfectly straight line.

Using these steps you will be able to save big on sheathing your roof. On top of this underlayment goes a slip which protects the material from tearing as the metal roof expands and contracts with changing weather. Keep these tips in mind when roofing in hurricane areas. Position the first piece of plywood or oriented strand board sheathing on the bottom edge of the rafter tails at one end of the roof.

If you have chosen to use a rigid roofing metal wood shakes or shingles tile etc you can use 1 x 4 slats instead. For vaulted or cathedral roof construction provide a free ventilation path from eaves to ridge between all rafters. The connection between the roof sheathing and the structure is a vulnerable point that is known to fail during a hurricane. Preparing your plywood sheets using a string line mark a line to guide the first row at the eaves.

Install baffles providing a minimum of 1 inch of clear space between framing and or under roof decking at eaves to ensure that ceiling or roof insulation does not block ventilation paths. Once the roof rafters are perfectly aligned it is now time to prepare for the plywood sheeting. The most common scenario is a home that has rafters set approximately 16 inches apart.
