Over the years corrugated roofing systems have benefited from many aesthetic and “roof integrity” system specific improvements, which now makes it a considerable alternative to conventional asphalt shingle roofs that go into landfills after 15 years of service. Although metal roofing is more expensive than asphalt shingle, corrugated roofing is quite affordable compared to standing seam. There are now, many corrugated roofing systems that can be used for home re-roofing projects. However, keep in mind, that metal roofing systems with exposed fasteners may require re-tightening some every 10 years or so. Also, should you decide to invest in a corrugated roofing system, I recommend that you go with aluminum, or galvalume steel corrugated roof system coated with Kynar 500 coating, not the cheap acrylic paint finish, which will fade quickly.

Union offers both exposed fastener metal roofing system and concealed fastener standing seam metal roofing systems for residential, commercial, and post-frame metal roofing applications. As the name implies, exposed fastener metal roofing systems use screw fastener system that are visible on the exterior of the metal roof surface after installation. These exposed fastener metal roofing systems are economical, and this type for metal roofing system has been in service for decades, and are extremely popular in a wide variety of residential and commercial metal roofing applications. In concealed fastener metal roofing systems such as our standing seam metal roofing system, the screws are completely concealed and protected by the steel roof surface. This metal roofing system gives standing seam panels very clean, aesthetically pleasing lines. The standing seam metal roofing system also exhibits the very best in weather resistance and durability since the metal roof fastener systems are not exposed to the outside elements. We offer the three primary types of standing seam metal roofing systems; screw flange, snap lock, and mechanically seamed system. Each of these standing seam metal roofing system designs uses a slightly different method to secure the panel to the metal roof.

When it comes to hail damage, corrugated and standing seam metal roofs can take the hits equally well with little to no serious damage. Corrugated and standing seam metal roofs have impact resistance ratings based on how well they hold up to impacts. Many systems have such high impact resistance ratings that your insurance company might reduce your insurance rates. The main thing to keep in mind here is the resistance ratings. These ratings vary in both corrugated and standing seam metal roofs, depending on the material quality. Corrugated and standing seam metal roofs with a Class 4 rating should take a hit from hail measuring up to 2 inches, without fracturing or splitting at the seams.

While the cost of corrugated metal will be similar to asphalt shingles, standing seam featuring improved design, thicker panels and better warranties can seem very expensive in comparison. With standing seam, materials and installation costs will be roughly two to three times the cost of corrugated metal or shingles. However, with standing seam, you’re not going to have to buy another new roof for a very long time, if at all. Either corrugated metal panels with exposed fasteners, or standing seam metal roof with concealed fasteners will last significantly longer than asphalt. Hence, either system can be a smart investment in your home.

Modern, corrugated metal roofing panels are primarily made out of galvanized steel (G-60 low-end, or G-90 better quality) in the form of U, V, Ribbed, 5 V crimp and similar metal panels. — Typically, corrugated metal and R panels are employed as metal roof or wall system comprised of 32 to 36 inches wide corrugated panels held in place by exposed screws / fasteners color-matched to the paint color of the metal panels. Caulking is used at connecting points of overlap in between the panels for water tightness.

During the installation, corrugated metal panels are overlapped by one or two ridges, through-fastened onto the roof deck or frame, and commonly sealed with caulk (in between the corrugated panels at the point of overlap) to keep rainwater and moisture out. Needless to say caulking is the least permanent part of the corrugated metal roof.

Corrugated metal and standing seam metal roofs hold up to lightning equally well. The likelihood of a lightning striking a building is actually reduced when it has a corrugated or standing seam metal roof. The possibility for damage from lightning, on the off chance that a lightning strike does occur, is practically non-existent because it is made from metal forming a Faraday cage, which will protect the structure and help dissipate the electric charge. Thus, your will not catch fire. Many insurance companies will give you a lower rate for having a metal roof, especially in areas where wildfires are a common problem.

Modern corrugated metal panels offer superior corrosion-resistance, energy efficiency, and can provide an economical roofing and cladding solution for commercial, agricultural, industrial, and even residential uses. Corrugated metal panels are usually made from thin-gauge steel, usually a 29 or 26 gauge steel, which makes it economical and practical, when it comes to covering large areas of roofing surfaces. Corrugated metal roofs are more practical and longer lasting than asphalt shingle roofs, and they cost much less than standing seam or metal shingles.

Nowadays, metal roofing is enjoying some impressive resurgence in popularity and demand, whether it’s standing seam, corrugated metal sheets, or ribbed metal panels. Corrugated metal panels are often used in commercial and low-end residential applications, but standing seam is becoming a lot more prominent and extremely popular in high-end residential and commercial retrofits and new roof installations. Both of these systems have their pros and cons that must be considered before deciding which particular system will best suit your needs.

Corrugated metal panels can also be made from galvanized, galvalume, stainless steel, and aluminum. Normally, a corrugated metal panel does not have a lot of thickness in terms of metal grade, which makes it quite economical and hence affordable, but it may well require some maintenance every once in a while, including the exposed fasteners re-tightening and potential re-coating applications.

Greetings: Nice site, need info. I am in st pete FL and have a flat roof, torch down, aprox 30 X 35, 1 story. Would like to frame in a hip roof and cover it with corrugated metal or go with a shed roof, maybe a 4′ knee wall. My intent is to eliminate the flat to keep the home dry and the water to run off while I fix anything underneath and give me room to run copper or ducts, would only have 2 penetrations, electric and plumbing vent. Give my email to any contractor wanting the work.

Corrugated steel panel presented above is LEED certified, inexpensive roofing solution for commercial and industrial uses. It is light weight, provides solar reflectivity, and good thermal emmitance, which will help keep the building cool. The downside of using corrugated and ribbed metal roofing systems such as 5-v crimp panels, R panels, U panels, and V panels, is that most of these systems come with exposed fasteners. For comparison, standing seam metal panels have concealed fasteners, which offers higher degree of weather and water tightness, but standing seam is a significantly pricier option.

With the reputation of strong ridges and uncompromising stability, the 1 ¼ Corrugated metal panel is the preferred option for professionals who value a low margin with exceptional quality. Versatile in industry applications, 1 ¼ Corrugated endures with durability.

Corrugated roofing panels can be made from aluminum, galvanized steel (G-60, or G-90 steel), galvalume coated steel, and stainless steel. When going for a long lasting economical solution, galvalume steel provides an optimal combination of cost effectiveness and material longevity and reliability. When finished with a Kynar 500 paint finsh, corrugated metal roofing can provide significant energy savings and qualify for LEED building credits issued by the US green building council.

Metal, namely copper, has been used as a roofing material since about 970 BC. Corrugated metal panels were invented the early 1800’s. It was the “new and improved” metal roofing system featuring wavy or ribbed panel profile. Corrugating the sheets of metal, which was hot-dip galvanized iron at the time, increased their strength and longevity.

Yes it can be. Since corrugated metal is one of the easiest metal roofing systems to install, this can therefore be a DIY job for a handy person, provided the installation would take place on a simple, gable-style roof.
