How to Install Metal Roofing on a Shed
One of the most important decisions for how to install metal roofing on a shed is the choice of roof material. There are many choices in materials and each will give the homeowner different benefits and drawbacks. If you decide to use asphalt shingles or another less expensive roofing option, then there is no need to change the appearance of your shed. If you choose to use slate or another more expensive option, the shed can be made more appealing, but you must keep in mind that you may be adding a layer of additional maintenance to the shed. This extra maintenance can lead to a longer life of your shingles.
First, how to install metal roofing on a shed begins with the preparation of the roof. Use all available tools to make sure the surface is clean and smooth. Apply caulk to all joints and seams to prevent moisture from building up between the roofing materials. If you have to drill into the roof, use drywall screws because water will not build up under the shingles if there is any. Use flashing to seal raised areas, like on a gable or pitched roof.
After installing the roof, you will next need to prepare the deck beneath the metal roof. Use drop ladders to install the decking on the roof, starting at the bottom of the shed. To prepare the decking for installation, use an adhesive to adhere the boards to the floor joists. Scrap excess decking off the bottom edge of the shed and cut plywood strips to fit below the decking. Drill and screw in any drain holes and prepare the deck by painting it with the same color as the rest of the shed.
The final step in how to install metal roofing on a shed is the installation of the metal shingles. Use drop ladders to install the shingles one at a time. Lay the metal shingles evenly across the decking. Press them slightly together to ensure even coverage and apply additional pressure when installing thinner ones. Continue installing the shingles until the entire shed is covered. You may need to add additional nails or screws to close the shingles in place.
After the shingles are installed, you may want to install the metal overhang as well. This is especially helpful when you live in areas where snow can be present. A metal overhang provides insulation against cold air coming in through the shed’s window. To install the overhang, position the shed’s framework so that its side walls are perpendicular to your shed’s side wall. Cut the metal to fit, twist it together to form a U-shape, and staple it to the frame.
Finally, install the silicone sealant to finish the job. Be sure to follow instructions carefully when applying the silicone sealant, especially for large or long shingles. Apply several layers to guarantee proper coverage. Once you’re satisfied with the appearance of your new roof, you’ll know how to install metal roofing on a shed.
