Removal of an Old Roof and Installation on the Purlin

Eternit is a dangerous material to inhale if your roof is old. When removing them, you must use a respirator.

A new roof is a long-term investment. I recommend that you inspect the roof purlins as well as the rafters. If the roof is in bad shape, it may be worth rebuilding.

A base sheet is required for a metal roof. It serves the main purpose of protecting wooden purlins against water. Metal roof panels are connected by overlapping joints so water can always get under. You are protected by the base sheet.

It is recommended that you choose a bitumen or plastic base sheet. They won’t absorb water. They don’t absorb water. However, I recommend that you choose one that can absorb condensate.

You can install the base sheet horizontally or vertically. Vertical placement requires that the distance between the rafters and the base sheet must be at least 30 cm. Vertical placement requires that you measure the length of your sheet so it is positioned over the sides.

You should also make sure that the lengths you cut are not too long to reach the sides. The sheets should be long enough that they don’t need tightening later. The base sheets can all be cut to the ground and lifted up. Start from one sidewall, then work your way to the other.

With large-headed staples or nails, the base sheets are attached to the rafters. The sheet should be free enough to allow water to flow between the rafters.

Next, install the next sheet panel. Overlap the first by about 20 cm. You will then attach the next sheet panel to the rafters. Continue this process with the remaining panels.

Next, place a purlin over the base sheet and rafters. These rafters are used to fix the base sheet, and later as a base for the roof metal.

You should make a smaller cut in the base sheet if there is a roof or any other structure that passes through the roof. The base sheet will then slide on top of it.


The purlin distributes weight evenly between the rafters. It also creates a pathway for air and wind to flow through. This is essential as it ensures that all constructions are dry and doesn’t contain condensate. The purlin is also protected by the roof metal panels.

Different metal roof styles have different perlin requirements. Some need less, while others require more. This information is provided by the manufacturer. You should follow their recommendations.

Installation of the Roof Panels

First, lift the metal panels onto your roof. You must be careful not to damage or bend them. You might consider building a sturdy wooden ramp to allow them to be lifted up.

Place the first plate onto the roof, so it extends 30mm beyond the edge. It is also recommended that the first plate be attached from the center using one screw. This will allow you to later adjust the position as needed.

Attach the second plate to the first one by using one screw. Both plates should be adjusted so they overlap and align. After you are satisfied with the results, attach them to the rafters using special sealed screws.

Continue doing so for all the roof plates.

Proper maintenance is the key to long-term health

Installing a metal roof takes a lot of effort. It doesn’t mean the job is done. To extend the life of a metal roof, it still needs to be maintained every year. At least once per year, the roof should be cleared of dirt. It is best to clean the roof twice a year, one in the fall and one in the spring. The roof can be washed with water and a soft brush.

In winter, snow will melt easily so there is no need to push it off. This depends on how the snow is angled. To avoid possible damage from the increased weight, you need to remove snow accumulations. To remove snow, you can also use something soft and blunt. You risk corrosion if you use sharp objects.
