In the last two years Buckley Roofing has paid out over $40,000.00 due to our roofing screws screwing into conduits installed above the bar joists in the fluts of the deck. With 98% of all roofing systems requiring screws for thier attachment this issue must be addressed. We recently had a claim where the short occured over a year after we had completed the project. There is a real possibility that someone will be killed before this practice of installing the conduits in the fluts is stopped. The requirment for the roofing industry is that the screws must penatrate the deck a min. of 3/4" and many times it will be 2" to 3". What can be done to stop this practice. I recently had an electrician tell my foreman that he should not screw in this area because he had run his conduits there. I didn't know he could rewite the spec book on how I was to install my roof all for his convience. Can any one comment on this subject? Thank you.
