About Me

Installing a New Roof

Hello, my name is Liam. I live in a rural community which is located about 200km away from Alice Springs, Australia. Life in the Outback can be hard, so the entire community needs to look after itself. Since I moved out here from the big city, I have learnt lots of cool skills that I didn't know before. One of these skills is roofing. When my neighbour's roof began to leak, he called me over and we worked together to install a new one. He taught me lots of cool tips and tricks which I have written about below. Enjoy!

4 Common Metal Roofing Mistakes to Avoid

Metal roofs last longer than many other types of roofing, but to ensure your metal roof lasts as long as possible, you need to be careful with it. In particular, if you are installing or repairing the roof, there are key mistakes you should try to avoid. Take a look at this list of common errors.

1. Positioning the Ridges Incorrectly

With most metal roofing panels, there are ridges throughout the panel, and there are two ridges at the end of each panel. Both of the end ridges feature a lip. When laying the panels, you want the short lip from the edge of one panel to lay on top of the large lip on the panel next to it.

2. Installing Screws Incorrectly

If you put in screws incorrectly, that may lead to leaks or to a roof that isn't tightly secured. To be on the safe side, always put the screws onto the flat parts of the metal roofing panels. If you put the screws on the ridges, you won't be able to get them flush with the metal.

Also, make sure to tighten the screws. If there's a wobble, the screw may come unattached, especially in wind. At the same time, don't overtighten the screws, or that may cause distortion in the metal.

3. Relying Too Much on Caulk

Caulk can be useful for addressing small issues with your roof. For example, a bead of caulk can help to secure a threadbare screw or help to secure flashing in place. However, some homeowners rely too much on caulk, and that can backfire and fail.

If possible, try to use the caulk as an adhesive or watertight sealant. Don't rely on it as a standalone patching material. For example, if your roof needs a small patch, don't just drizzle caulk on the hole and hope that it will dry and protect your roof. Instead, put down some caulk, and then, place a metal patch over it. That also protects the caulk from the elements, helping it to last longer.

4. Allowing Too Much Overhang

When you install the metal roofing panels, you should have a bit of overhang near the eaves. However, you only want a couple centimetres or so of overhang. If there's too much overhang, that part of the panels won't be supported, and that could lead to damage down the line or instability in wind.
