Hurricane Construction

This may be off topic, but I have a couple questions regarding roofing materials and plylox hurricane clips. First, any opinions on which roofing product held up better in this year's storms, ashphalt shingles or metal roofing? Also, plylox clips were mentioned earlier in the season, any first hand comments on how well they work?

Thanks!

Sandy

my understanding is metal roofing is very easy to be lifted off. Also, the insurance industry says the plylox clips are the safest way to use plywood. If you run a search for plylox I think you will find the article.

Thanks depotoo. I suppose in the application of metal, whether it is screwed down or nailed down would make a difference. We're in the process of building a house in the Bahamas and need to make some decisions soon regarding roofing material and hurricane shutters. That's why I was looking for first hand accounts on the Plylox clips and roofing.

Lutra, the old hurricane code of Dade County used to require cement tiles that were mortared in place. My parents had this kind of roof (hipped as well) and they got through the northern eye wall of Andrew with zero damage.

I would never reccomend anything else.

I was just beginning my research on roofing before Ivan, because it is about time for a new roof. They now make steel roofing that looks like shingles and withstands very high winds. I believe the insurance companies will give you a credit for this type of roof. The down side is it is about twice as expensive as superior shingle roofing. However, it is supposed to last something like 40 years. I'll try to find the website for you.

I was wrong -- its not steel roofing -- its metal. I have attached the question and answer page from the site that talks about the wind speed it can withstand http://www.metalroofing.com/teampublish/60_165_841.CFM

I had my roof in the Keys replaced with metal (Galvalume is the brand name I believe) about two years ago. I had a permit and engineering signoff on materials and installation method meeting Metro-Dade-county code. The installation included screws every six inches on the seams. The screws are galvanized and have a hex hed and neoprene washer.

I'm not sure if this roof is considered more wind resistant than cement tiles as mentioned above, but I know it meets the code here.

Some of you may know this, but my cousin had a new roof put on her house, a few weeks before hurricane Ivan struck. She only lost a couple of shingles during the hurricane. Everyone in the neighborhood and around wants to know who she used so they can use them.ANYWAY....
the shingles were nailed in a few places (each shingle) NOT stapled in The nails held alot better!

Yeah, if there's one hurricane construction tip I know, it's --

Staples are for PAPER, not houses.

If your plywood, shingles, or front door are attached with staples, you might as well be in a trailer during a hurricane. Staples are a big cause of roof failures, AFAIK.
