i have been researching these roofs more months now. are there any drawbacks at all, besides the price, to these roofs? also, if they have been tested and passed at 200mph, why are they only warranteed at 120? is there a metal roof at all that is warranteed for more than 120? thanx

Don't mix wind speed with tasting and warranties. The Florida Building code has a wind map. You determine where you fall and as you are in South Florida you could be in the 140 to 150mph zone. From there you must determine the building location, height by width ratio, roof slope and overhang size to calculate uplift pressures required to meet the code. Manufacturers test their product to positive and negagtive wind pressures with the negative pressure the worse condition. The FBC then takes the average rating of 3 tests and then applies a 2:1 safety factor and publishes this rating in their product approval report. In choosing a roof, ensure that it meets the building code by having a product approval. We are a manufacturer of these products and as well warranty our products to 120 mph however we are tested to -270 psf and as a 100mph wind pressure is around 31.5 you can see that it is more contingent on the roof and house construction than the roof covering. The FBC also calls for the removal of the existing roofing material and upgrading the sheathing and fastening.

thanx for the answer. i have another few. i have found a company called feasel roofing that i liked. i also like the stone coated steel from gerard. this is what i was thinking about going with. my question is, i have checked out feasel as best as i know how. i saw that they are licensed in fl and have no complaints on their licenses. but, how else can i check on these two companies as far as workmanship? is there any other way i can protect myself from shoddy work? am i left to fend for myself? erica

I would ask for references of past jobs ... go talk to the homeowners about their total experience with the contractor. Find out who their job foreman was. Make sure that same person will be on your job if all went well with them. Todd Miller

Also, make sure you know what sort of workmanship warranty you are getting from the contractor, in contrast to the materials warranty from the manufacturer. Todd Miller
