TOPIC: Installation

Holes Punched in Sheathing Near Ridge

Return to Installation

Return to Forum

We are doing a remodel of our single story home by adding a second story and a partially finished attic. The attic will be insulated on the interior with open cell spray foam. We just had a metal roof by Englert installed. In the course of doing so the roofing contractor punched holes in the roof on both sides of the ridge to anchor safety harnesses. The holes were not cut but looked to be punched through the OSB. So now we have about 5 pairs of holes. I mentioned my concern with this to our contractor and he said they would patch with wood on the inside before foaming and that the ridge cap would cover the holes and keep water out. If I wanted he would ask the roofing contractor to install flashing over holes before installing the ride cap. Tried to upload pictures but couldn't

A couple of questions:

  1. Is this common practice? Is it best practice? Is it wise?
  2. Isn’t there a way to rig a safety harness without punching holes in the roof deck ?
  3. Will his plan work?
  4. Has the roof integrity as far as moisture management been compromised?

Different contractors do things differently and every job has its own particular details as well that may necessitate different things. I would ask him to flash over the holes and also seal them well as far as trying to retain the integrity of the underlayment. Being at the top of the roof, though, I think you will be okay. Sometimes they will actually leave the anchors in place.
