Building an Outdoor Kitchen: Roofing and Shade Building an Outdoor Kitchen: Roofing and Shade
There are lots of choices for an outdoor kitchen roof. The type of roof you choose for your open-air kitchen will depend on the location and design of your kitchen. You can locate your external kitchen in an enclosed porch or patio of your main house. In this case, the roof over the external kitchen is an extension or projection of the main house roof. Therefore, you are limited in your design options. If your kitchen is a standalone structure in a garden or courtyard, you have more design options for your roof. It can be a double-sided pitch roof, flat roof or 4-hipped roof, all to your tastes. Here are ways of installing a steel ribbed roof for your kitchen.
Step 1 - Calculate the Number of Sheets
Compute the amount of steel sheets you need by measuring the span of the roof ridge in centimeters. Divide this figure by 112, which is the size of the standard steel sheet. This will show you the number of rows of steel sheets you need. Compute the size of the roof inclines, the length from the top part of the kitchen roof to the border, in meters. Break down this figure by 6 to determine the number of columns of steel covering you need. Multiply the quantity of columns by the quantity of rows to determine the quantity of steel covers you require.
Step 2 - Count the Number of Ridge Caps
Work out the quantity of ridge caps you require by measuring the sides of the roofing and the size of the ridge at the top part of the kitchen roof in meters. Break down this figure by 1.83 to determine the number of 1.83 meter ridge capping you need.
Step 3 - Insulate the Roof
Protect the roof with conventional roofing insulation by fixing every 2 to 3 centimeters on the exterior ends of the insulation layer, as well as every 15 centimeters on the inside. Insulation layer must be overlapped a minimum of 7.60 centimeters.
Step 4 - Install Covering
Start the covering by putting your steel sheets at the first corner of the kitchen roof, over-hanging the side of the kitchen roof by 5 centimeters. Utilize recommended roof nails with leak-proof rubber washers to fix each metal sheet. Nails must be positioned on the middle of the roof ridge of the metal where it curves away from the roofing instead of in its direction. Never hit nails into the roof ridges close to the sides of the metal sheet. Use approximately 20 nails for every metal sheet.
Step 5 - Overlap the Sheets
Position the next steel sheet alongside the first sheet, with the junction of the pair of sheets overlapping. Add a bead of caulking between both metal sheets where they meet. Fix this metal sheet into position just like the first, and continue doing this process until the underside row is finished.
Step 6 - Put Successive Sheets
Position the first metal sheet of the next row just over the first metal sheet of the initial row. It must overlap the top part of the initial metal sheet by 15 centimeters. Fasten this metal sheet firmly into position and lay out every consecutive sheet to overlap the metal sheet beneath it, as well as the metal sheet to its edge.
Step 7 - Line the Edges
Once all metal sheets are mounted, line the inclined ends and the ridge of the kitchen roof using ridge caps. They should stop moisture from seeping in from the top and sides of the roofing where the ribbed bottom of the metal sheets might often be subjected to weather elements.
