Why should I buy #1 metal instead of #2? #1 metal has a 40 year Energy Star approved warranty which guarantees against fading to keep your roof looking new. #2 metal or secondary has no warranty and although it looks good when first applied it has a greater chance of becoming dull, and also where it is cut and at the edges of the panel it is prone to edge rust quickly. Why should I buy a standing seam roof? Standing seam roofing has a Trinar paint which is a superior paint all fasteners are hidden underneat the surface for a smoother, more apealing look. Why should I buy a metal shingle roof? If you peer the look of shingles, metal shingles last significantly longer than traditional asphalt shingles with a variety of styles and colors. Why should I buy 26 ga metal instead of 29 ga? 26 ga. is a bit heavier than 29 ga. and therefore more resistant to hail and other types of damage. Why does my roof need ventilation? Without proper ventilation your roof will “sweat”, causing moisture to form and possibly damage decking or lathing or in the worst scenario cause damage to the interior of a home. What happens to metal if I store it wet in a stack? If metal is exposed ot standing water for a prolonged period of time it is possible for the paint to begin to bubble then peel thus causing the metal underneath to begin to rust. Why should I not cut metal with a power saw? Cutting metal roofing with a power saw, even with the blade turned backwards, heats up and sears the protective coating on the cut edge thus allowing rust to begin. What is the best way to cut metal? The best way to cut metal roofing is with an approved set of metal cutting shears. There are many types available including hand snips and power shears. Why should I not install metal directly to fiberglass shingles? Weather changes from hot to cold and metal roofing expands and contracts accordingly. This will case the metal to rub against the gravelly surface of the shingle, eventually wearing away the paint on the underside of the panel allowing rust to form and after time rust a hole through the metal panel. Why does pressure treated lumber rust metal? Treated lumber contains a chemical to “wolmanize” the wood which is corrosive to metal products. What does galvalume mean? Galvalume is a term used ot describe the coating on bare steel which contains 45% galvanized and 55% aluminum thus helping to prevent rust and maintaining a strong yet light panel. Can I install my metal using 1×4 lathe? Yes you can. Using an untreated wood 1×4 lathe would be fine. The only thign to keep in mind is that the metal can look a little rough and if while installing the metal you should step on a lathe it can crease the metal but all things considered it does work.

Best Way To Cut Metal Roofing

You can make a good cutting blade for sheet metal roofing out of a cheap circular saw blade. Go find your old used circular wood cutting blades, without carbide teeth, or buy the cheapest circular saw blade you can buy. There is no point in messing up a good carbide tooth blade. They can be easily re-sharpened. Circular saw blades usually cut about 1/8 inch wide. If you look at them, you will see the teeth are angled outward to make the 1/8 inch cut. But the blade itself is approximately 1/16 inch wide. So take the used or new blade and stick it in a vise. Use an angle (side) grinder to make all the teeth no wider than the rest of the blade. This is easy to do. If you do not have an angle grinder (like one a welder uses) then put the cheap blade in the circular saw and turn it against a grinding stone or grinding wheel. When you are done the teeth are 1/16 wide. All the grinding will be on the sides of the teeth. Do not grind the teeth off of the blade , only the sides of the teeth. When you finish, the blade’s teeth will be thinner, but the ends of the teeth are not shorter. This should take only a couple of minutes. Do not make the blade any thinner except at the teeth. This blade has no need of sharpening. It dulls up as soon as it hits the metal – and cuts fine. Now you can mount the blade in the saw and cut the roofing metal, but you are only removing 1/16 of an inch, a much thinner and easier cut. Metal roofing with ribs cuts easier from the back side(the down side when screwed to the roof). I use pencil lines, pop lines are too fuzzy. You can run this thin blade forwards or backwards, but after it makes a few cuts, the teeth are not sharp and direction makes little difference. This blade will last FOREVER. It will not need ANY sharpening. YOU, however, WILL need earplugs. The easiest place to cut metal roofing is on the grass. The metal sheets slide around too much on a bench or table. Lay a 2×4 on the grass and hang the end of the metal panel over the 2×4. Now your blade is not digging into the turf as you cut. I have cut painted and unpainted Galvalume metal roofing this way. If you get hung up or the blade is pinched by the metal, stop and adjust. The blade needs to keep moving so it does not get hot and mess up the paint on painted galvalume. P.S. You can get clean edges by running a 4 inch angle grinding wheel along the edge where you cut. This should be done RAPIDLY, to just remove the burrs. If you stop moving, the grinder will dig in where you don’t want it to. Don’t push hard on the wheel – just lightly remove the burrs left over from cutting. This makes a nice smooth edge if your cut was straight. I have found very little rust on these smoother cut edges and I live in a wet climate. I think the zinc in the galvalume migrates to the edge somehow.
