I ve stripped a few roofs with i w and it s extremely difficult to get back to the original deck.
How to remove ice shield from roof.
I had a roof that was stripped and re shingled 22 years ago 1989.
It is a 4 year old roof with the ice and water shield on structural insulated panels outer layer is 3 4 osb so we are not able to simply replace the plywood we need to remove the i w and build a new roof system 8 above the existing one for circulation reasons.
Sometimes shingles come off the ice shield better when it is cool.
Some work better removing the bulk of the shingles first leaving those who stick badly then peeling the ice shield off diagonally from one corner one or better two or three people pulling being careful not to back off the roof and one other person going along on the exposed surface with along handled driveway ice scraper like a mutt but sharpened breaking loose the places it sticks to the sheathing.
Hi my name is howard this is my first time using the forum.
However remember to be conscious of the weather as it can be more difficult to cover up lower sections of roof water flows down hill.
Open to any and all suggestions thanks.
Ice and water shield re roof i was told by i w manufacture that u can only have 2 layers then u need to remove the plywood and start over.
Start early in the morn and hurry up before the sun hit it.
It s a fairly low slope roof 2 1 2 12 pitch with a southern exposure and it takes a real beating from the sun.
Unless you hate future roofers that you don t even know yet do not cover the entire deck with iws.
Sometimes shingles come off the ice shield better when it is hot.
Good luck getting the shingles off the i w.
In that case tear off the bottom ice shielded portion of the roof before the shingles heat up and stick and stick together.
With that said i m pulling back a portion of my roof to tie a new roof into.
I knew it had an ice water shield underlayment around the perimeter because i was the one that installed the roof 22 years ago.
