I have a client that had a metal roofing contractor install metal roofing on her house four years ago. She called us concerned about a leak. I believe her leak is coming around a skylight, but 3/4 of the meatal roofing screws have cracking rubber washers. Could this be from overtightening the screws or is it from uv rays? I have installed metal roofing and we always started the screw with a hex head driver and a drill. We wouldn't tighten all the way with the drill. Another person would come behind the drill guy with a ratchet and hand tighten them, as not to pancake the rubber washer and cause it to split. What is your opinion?

Well, what is your opinion on the cracking rubber washers?	Guest User 2/6/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/12710/find/
I personally havent had a problem but I also dont use the cheapest thing. We also install with impact drivers wich seems to let you be in control unlike a drill. I understand the drill has settings but just seems way to inconsistant plus the batteries last longer in the impact.

are nails better than screwsa	Guest User 6/5/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/12713/find/
Screws will normally have better pull out resistance. However, many metal roofs have been designed and tested to perform just fine with nails. Always refer to manufacturer instructions.

I have seen it both ways but which is better? Placing the screws in the valley or on the ridge?	Guest User 9/1/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/12715/find/
