5V Metal Roof vs Crimped Metal Roof

I have a house with many large gables and valleys and a porch at the bottom of the gables/valleys with a low roof pitch. The house also has two round dormers. Would you recommend 5V or a crimped metal roof for this style house? Any other recommendations for other types of metal roofs that might be a better selection?

One of the great things about metal roofing is its wide variety of product designs. You can obtain virtually any look and combination of benefits you're seeking. When buying a metal roof, first, I believe you have to like its aesthetics and feel they are appropriate for your home. From there, there are many other considerations: Type of paint finish or other coating Exposed or concealed fasteners Clip or through fasteners Interlocking or overlapping panels Vertical profile or shingle/shake/slate/tile look Base metal Structural or architectural Obviously, I do not know the exact configuration of your rounded dormers but, generally, it will take a shingle-style product or a tapered standing seam for most such applications. Spend some time on this website looking for products you lile. Then, make inquiries direct with the manufacturers pertaining to your specific needs. Todd Miller

The choice of a 5-V metal roof panel for a structure that is to be utilized as living quarters is not advisable in my opinion. The temptation to install this configuration of metal roof is strong because it is at the absolute low end of the price structure for metal roofs and the homeowners may feel that because they will have a "metal roof" means that it will be the cure-all end-all for their roof concerns when in realite this false sense of quality will be short lived! The crimps on this roof panel is only 1/2" tall and this short profile must be punctured with the exposed fastners (nails or screws with gaskets) that are required to hold the metal on the roof. When you combine this fact with the expansion and contraction of ALL building products due to temperature variations this will provide you with the holes for the screws or nails being rounded out to a larger diameter and thus water inside the building envelope.

I just bought a home in Panama City Beach, Florida that is around 150 feet from the beach. The roof has to be replaced, and the current roof is a 5-V Crimp System. A contractor provided a bid to replace the roof using 30# felt, 24 ga. Galvalume mill finish 5-V Crimp System, and 6", 26 gauge galvanized eave metla along the roof edges. A construction manager advised me that I should not use the crimp system, but instead get either a Snap system or Standing Seam. Considering the location, and the fact that I don't know a thing about roofs, can you advise me on what method to choose, and whether the use of the galvanized eave metal is ok? The seller's realtor said that since the material warranty is for 15 years I shouldn't spend the extra money, but I don't want to have moisture problems to deal with 5 years down the road.

In my experience, metal roofing does increase home value which can pay for itself at resale time. Obviously, that is unpredictable though. One beauty of metal roofing is all of the variety of styles, types, finishes, and metals. Generally, the lowest cost will be an unpainted "sheet" product with exposed fasteners. Going to a concealed fastener standing seam, such as what has been suggested, will be an upgrade in terms of life expectancy as well as cost and, to most peoples' eyes, aesthetics.
