How to Build Corrugated Tin Roofing How to Build Corrugated Tin Roofing

What You'll Need
Chalked string
Tool for cutting tin
Ridge cap (ridge covered by a metal structure)
Vapor resistant barrier (A plastic or foil sheet that resists moisture)

When it comes to resilience, tin roofing steals the show. As for the dimensions, it is approximately 40 inches wide and 120 inches long. As compared to roofs with asphalt shingles, tin roofing is much cheaper. Tin roofing has progressed in leaps and bounds since the days of our ancestors. Not only do tin roofs now offer numerous colors, but could also be installed without any professional expertise. Cancelling your appointments for a day or two and focusing solely on the installation of tin roof by following the below mentioned steps, you could successfully build a tin roof.

Step 1 - Installing the Vapor Resistant

Cover the roof with the vapor resistant. Even if the roof has shingles, it would not matter as the tin would later conceal the shingles. A vapor resistant is primarily installed to counter the moisture under the tin. Pin the vapor resistant after every 40 inches approximately. In case of the resistant hanging over the edges of the roof, you can cut it after the installation of the tin.

Step 2 - Marking the Measurements

For starters, pick the roof side from where you will begin. Tin will cover the roof vertically, from one edge to the other. Since the width of the tin is exactly 42 inches, mark 40 inches from the roof’s edge. Mark 40 inches both at the bottom and at the top. It would be more convenient, if a willing assistant holds the chalked string at one end while you mark the other edge.

Step 3 - Placing the Tin

Bring the tin into line with the chalk marks. The tin should cover the whole length vertically from bottom to the top. Start from the bottom with a 120 inch tin piece, ensuring that the tin piece extends 2 inches beyond the edge. With the help of metal nails, nail down the tin. Then grab the next 120 inch piece. This time making sure the second piece overlies 2 inches of the first piece. Continue in this fashion till you reach the edge. If there isn’t enough space to fit another 120 inch piece, alter the piece accordingly with the help of a tin cutter, and position the tin piece in the same pattern being followed. The nails should be at a maximum distance of 12 inches. Ensure the nails are driven into the bowl-shaped portion of the tin. It is the job of the vendor to provide you with nails of a similar shade as the tin.

Step 4 - Overlapping

Now move horizontally, covering the next layer of tin, and back to the bottom. The turned-in rod of the next sheet now covers the turned-in rod of the previous sheet.This should give a fine overlapping effect.

Step 5 - Ridge Cap Installation

Once you have covered the whole roof with tin, it is now time to set up the metal ridge top. The standard dimensions of the ridge top are usually 120 inches long. These should overlap around 2 inches. Finally, nail it down with the provided metal screws. Now you have a finely done corrugated tin roofing.
