Metal roofs - why would a city like Coral Springs care?

Not saying that this is why CS doesn't want them, but this thread does remind me that whinging and moaning is a sport down there, especially with the transplants from two particularly large states.

How do you figure they can do 3 shingle jobs to 1 metal? Most roofers do them in 2 days and I'm talking standing seam done to code.

After a hurricane, expect semi-skilled out of area labor. Three tab is the primary school for roofers. Put a crew of them with one supervisor and a bunch of utility knives and power hammers and done. Metal takes more experienced crews and measuring/cutting. Yeah, they can be fast, but for a roofing company looking to make a fast profit and get jobs done, each of the experienced crew becomes a supervisor of transients.

I had my roof in Alabama replaced with three tab a few years back. Start to finish - tear off, deck repair, underlay and trim, shingle and cleanup was all done in a nine hour period in one day. There was no inspection other than my watching. A similar replacement on my house in Florida took five days, but the cement tiles were more laborious to strip, and the two inspections during the work slowed the workflow.

Prior to that, when Andrew came through, my boss was living in a condo in Kendall that had tile roofing. At a distance, it looked like someone had taken a pepper shaker to his car. Closer up, it was all the dents and damage from the broken roof tiles. When my roof needed to be replaced, I remembered that, looked at the difference in cost vs. resale value and never looked back.

My Cuban neighbor once told me that some homes in Cuba were built with a solid concrete roof, more like a parking deck than tile, because they stood up to hurricanes so well.

The comment about the noise of metal roofs fits in some situations. I have a little old house on one of my properties that sits under an oak tree. During the years that the oak is producing acorns there is a constant "ping" that goes on day and night as they hit the metal. That metal roof is only supported by the purlins and acts like a drumhead. A different support structure would reduce that sound significantly.

I don't think any of the higher risk hurricane areas even allow 3 tab shingles. I know they don't in Indian River. Architectural shingles have a much higher wind resistance. If a metal roof is installed properly it will withstand 160 mph winds. But you have to do your research. You want a roof that's 24 gauge and attached properly. As for noise, the plywood sheathing and peel and stick membrane absorb most of it.

They obviously did when I lived there. The deck and hurricane straps are the important factors. Face it, when a tree hits your roof, it doesn't matter if it is tile, arch, metal, or three tab. There WILL be damage. Guess which of those are more expensive to fix? Agree with you on the noise abatement.
