How to use roofing felt to level subfloor for laminate.

Cut the felt to size with a utility knife. Place the first shingle in the dip. Uneven osb subfloor the subfloor beneath. While preparing to lay 1100 square feet of hardwood flooring we discovered significant variation in the osb subfloor that will serve as the nailing surface for the hardwoods.

Measure the felt to match the measurements of the low spots in the subfloor. Cut the felt at the end against the perpendicular wall by laying a level across the width of it and running a utility knife along the level. Roll out a course of roofing felt on the floor alongside the wall where you want the flooring courses to start. Flip the piece of felt over so it s not curling up at the ends.
