If your roof sheathing is damaged, you should remove it right away. Roof sheathing is joined to trusses and rafters which gives support to roofing materials and it is commonly made from plywood or oriented strand board. Though you don't need special skills to remove roof sheathing, it is a laborious task that requires following safety procedures as with any roof repairs. Here are some tips to remove roof sheathing.
Prepare to Work
For this project, you will need safety glasses, safety gloves, safety harness, an extension ladder or scaffold, chalk, caution tape, tarp, hammer, a circular saw, tape measure, a pry bar, and nails. If your home has more than one story or the sheathing is unsafe to walk on, access the sheathing with a scaffold. Mark the work area off with yellow tape so others will not come into it and cover shrubs you don't want damaged with canvas tarp.
To access the sheathing, you need to remove the shingles. Remove the shingles with the pry bar inserting the flat end below the shingles and pulling them up. Inspect the roof for nails and remove them with a pry bar. Buy replacement shingles of the same type.
Remove the Old Sheathing
For extra safety, get someone to hold the ladder while you climb up or secure yourself with a safety harness to a steady chimney. Mark off rectangular sections of sheathing to remove with chalk. Begin removing sheathing at the peak so you will always have a place to stand.
Insert the end of the pry bar at the seam between two boards pulling the edge from the rafters as you stand on an adjacent board. Try to pry off the boards by hand. If you have trouble removing the boards by hand after pulling it from the edge, pry the rafter nails with the pry bar.
Remove remaining boards in the same manner. For easier removal, hammer below the sheathing. Drop waste onto the ground below.
A faster way to remove sheathing is with a reciprocating saw. Mark a rectangular section with chalk and cut along his area with the reciprocating saw. If you want to save good pieces of sheathing, remove them with the pry bar.
Once you have removed the old sheathing, you are now ready for a new installation. Working on roofs can be tricky so remember to practice safety. If you don't trust your skill or have a steep roof, a professional roofing company such as A-1 Roofing & Siding is your best option.
