Corrugated roof panels are made from metal, fiberglass or polycarbonate and typically install over a system of purlins. They're popular for workshops, sheds, boathouses and other sheds due to their lasting durability and simple setup. The panels come in basic widths and lengths and are attached using screws with flexible washers.
Depending upon the roof product, a metal roof can last 40 years or more - purlins for corrugated roof. Metal roof easily sheds snow and ice and does not absorb water. It will not rot, split or fracture, and can't be damaged by termites and pests. And, unlike any other kind of roofing, the color of pre-painted metal roof can be altered to match new exterior color pattern.
One trick to separating panels from a package is to "whip" the panel to force air below it (so they don't stick). The light weight of a corrugated metal panel is another advantage. Compared to asphalt shingles that weigh approximately 2. 5 lbs. per square foot, metal roofing panels just weigh.
3 pounds per square foot, which allows the panels to be set up over existing roofing materials. This conserves costly disposal and removal charges, and makes the panels simpler to lift and set up. (Eventually, local building regulations and the condition of your roofing's foundation will figure out if you can set up metal panels over your existing roofing.) On this building crew, one male provides the panels to the 2 installers on the roofing.
This reduces heat retention so less heat is transferred into the structure. Attach the panels with a 2" overhang. Plus, metal roof is the favored roofing option in hail-prone locations. Hail causes traditional roof materials to break and divide. Hail will not permeate a metal roofing system. In general, fall-restraint harnesses and security lines must be utilized by anyone dealing with roofing.
Wear versatile rubber shoes that grip the metal when stepping on it. Never set up metal roof in the rain, because the slick, damp surface of the panels can essentially ensure you'll slip and fall. And never deal with metal panels in high winds, due to the fact that the wind can bring an unfastened panel airborne, in which case it becomes a big flying blade and really dangerous.
Do not follow their lead!If you fall off a roofing and land on the ground, you might break your neck. Always wear the appropriate safety equipment. If the packages of metal panels are saved outdoors on the ground, use plastic sheeting below the bundle to minimize condensation of water from the ground onto the panels - installing metal roofing on a shed.
Shop the panels at an angle to promote drain off the package. Secure the kept panels with a loose -fitting tarp to protect from rain or snow however also permit air flow. Tin snips, powered shears or an electrical nibbler tool are advised to cut the panels. Cutting the steel generates slivers and metal chips that should be gotten rid of to prevent scratching the painted finish.
You'll find it useful to have three set, for left edge, best edge and centerline cuts. To help assess the overhang, attach a layout string parallel to the eave as a guide. A variable-speed cordless drill/driver is all you need to drive the screws. Recommended securing pattern. For securing the metal to wood framing, use sharp-pointed, color-coated screws that quickly permeate the metal to engage the wood.
Hex-head screws help hold the fasteners steady while driving them. All screws ought to include an EPDM vulcanized, bonded washer to prevent leaks and damage to the panels throughout setup. Side laps need to face away from the dominating wind. If you're unable to utilize complete panels on your roofing system, follow the setup sequence (left) for proper building and construction.
Whenever possible, nail in the valley between the ridges, where the roof is closest to the wood. The fasteners of choice are color-coated screws with sharp points and EPDM vulcanized bonded washers to seal out water. For gable roofings, position the metal sheet at one corner of the roofing system, overhanging the edge by 2 inches.
Fasten with about 20 screws per sheet. Work toward the sides of the roof deck, cutting panels to fit as needed. Place a second corrugated sheet next to the first with the ridge of the panel overlapping. For a more secure roofing system, apply caulk/sealant between the two overlapping sheets. Screw the second sheet through the first and into the framing.
This crew develops a lot hip roofings to a typical pitch, and they made a wood jig to guide the matching panel's cuts. For the 2nd row, put the first sheet above the first sheet of the very first row. The upper sheet should overlap the very first by 6 inches. Attach the sheet and finish the second row in the same way as the very first.
