Corrugated Metal Roofing Installation

Installing Corrugated Metal Roofing While it is not absolutely necessary to be an experienced roofer to install corrugated metal roofing, it is advised that you get sound instruction and consultation from someone who knows the pitfalls and drawbacks involved with the process. If you decide to go the route of contracting or consulting a professional group, make sure that you are getting assistance from one of the better and more reputable organizations. It is also advised that you have some experience doing some sort of roofing. First of all, you are going to need special tools to work with the metal. There are also many things that you need to be aware of so that you don’t void the warranty in the process of the installation. If you intend to install corrugated roofing on your own home, it is advised that you have written instructions that come directly from the manufacturer that detail specifics about your project. If you hire a roofer for the job, make sure that they follow the manufacturer instructions as well. In general, the installation of this type of roofing is performed by fitting metal sheets over your existing wooden frame. When done properly, an overlap will occur, which allows the pieces to fit snugly in place according to the steepness of the roof. The following instructions should serve as a rough guide: To calculate the number of sheets that you’ll need, measure the length of your roofs ridge. Divide this by 112 (cm), which should be the average width of a standard metal sheet. Now that you know how many sheets you’ll need, you can measure the length of the slope of your roof. This is the distance from the top of your roof to the edge of the roof. Find out how many columns of sheeting you need, and divide this number by six. Now, multiply the number of rows by the number of columns and you will know how many total sheets will be required. You may now begin the installation but putting your corrugated metal sheet at one corner of the roof. At this point, the wooden frame should only be covered by roofing felt. Hammer nails into the sheet periodically to secure its position. Ideally, the nails should be around the center, or lowest point of the metal bend. Try not to drive the nails into areas that are near the edges of the sheet. On average, you should place about 20 nails in each sheet. The second metal sheet should be placed next to the first sheet, with one hump overlapping. Hammer this sheet in the same manner that you did with the previous sheet, and repeat the process until the bottommost row is complete. Ridge caps should be hung at the bottom edge of the metal sheets, curving over the lip of the roof. Hammer these ridge caps into place in order to seal the bottom of the sheets. This will cover up the unsightly corrugations, look better, and prevent water leakage under the metal. 40 nails for each length of ridge cap is a good general rule of thumb. The first sheet of the second row should be placed just about the first row. The overlap should cover the top of the first sheet by about 2 cm. Now, hammer the second sheet into place and do each subsequent metal sheet in the same manner, overlapping with both the sheet below it and the sheet to the left, if you are moving left to right. Repeat the previous step until the whole roof is then covered with the corrugated metal sheets. Make sure to find the roof edges and ridge the roof with ridge caps. This will prevent water leakage from both the sides and the top of the roof that is exposed to the air and elements. When this is done, you are finished. Congratulations on your new roof.

Search Add New Question Should a support be used under the corrugated roof? Donna Nelson Yes. The purlins support the panels. If you are placing metal panels over an existing roof, you still use purlins. The purlins not only give you something other than the existing roof to accept the roof panel fasteners, they also create an airspace between the roof panels and the existing roof. Without the purlins, the roof panels would sit directly on the existing roof, you would get moisture building up under the roof panels. Thanks! Yes No Not Helpful 6 Helpful 17 Where do I put metal screws on a roof to fasten it down? wikiHow Contributor On a corrugated roof, always fix at the top of the ridge to minimize the run -in of moisture. Thanks! Yes No Not Helpful 15 Helpful 24 Do I paint bitumen onto a corrugated iron roof? wikiHow Contributor Bitumen will do well. My old cottage is so close to the sea that the bitumen has to be reapplied every couple of years. A caveat: Do not do what I did – I tried a fancy silicone paint to go on top of the bitumen. There was some chemical reaction and all the silicone paint did was act as a paint remover and the bitumen came off in great strips. Thanks! Yes No Not Helpful 1 Helpful 4 Which side is up and which is down? wikiHow Contributor If buying new panels, most of them nowadays have a sticker stating which way is up. Thanks! Yes No Not Helpful 5 Helpful 9 Does it break if you stand on it? wikiHow Contributor Roofs aren’t for standing on. There’s a good chance you’ll damage a corrugated roof by standing on it, especially if it’s PVC. Thanks! Yes No Not Helpful 3 Helpful 5 Can I get roofing sheets that are 36″ wide by 14′ long? wikiHow Contributor Yes, most suppliers will have 36″ wide steel panels and will cut them to the length you want. Thanks! Yes No Not Helpful 2 Helpful 4 What’s the approximate difference in cost between fiberglass and metal? wikiHow Contributor It depends on the length you need to cover without waste. Compare the total cost in your case between the options besides the durability and also with the plastic version. You need the support strips, which can add to the cost, but usually you don’t need the strips with the aluminum panels. Thanks! Yes No Not Helpful 10 Helpful 10
