Because of tree damage I had to reroof my house. Roofers used a tack so long it busted up my decking from underneath. The whole attic need to be emptied and cleaned. Any addvise.

rdacus, start a new post, not add to an old one. And explain in more detail why your attic needed to be cleaned.

First its not a good idea to piggyback your question on another thread. This can lead to confusion. So I've moved your question to its own thread.

Advice as to what?

How much of the roofing nail is sticking through the sheathing? Normally should have about 3/4''.
