In an ideal scenario, when you purchase metal roofing materials online and have these installed in your home, they should last a lifetime.
But despite the many benefits offered by Colorbond roofing, there are some property owners who have encountered problems with their roofs early on. In order to avoid these problems and have a roof that is both beautiful and functional (and will be sure to last a lifetime), here are some helpful tips that you can follow during installation.
Standard drip edge
If you are going to install metal roofing for a standard drip edge, start out by folding the roofing sheet and then cutting and folding the standing seam panel over the drip edge. Make sure you cover the eaves and gable ends.
If the roof is going to be laid on a flat layer of existing roofing, use a C-D edge trim. This will allow you to hide the drip edge and other exposed edges of the current roof.
Using hand tongs, create valleys from roof pans by refolding its male and female legs. After that, crease the valley using a site break.
Remember to install the drip edges and ridge caps first. After that, valley fit and then attach the cleats. The bottom portion should be folded around the drip edge while the roofing pans are hemmed into the valley hems.
In order to create a smooth transition at points where the ridge caps meet on gable dormers, create a bow-tie cleat.
If you are going to need a vented ridge cap, make sure that it is installed before the pans. This makes the task easier for you and helps you avoid scratching the pans.
On the other hand, if you need to install a sidewall flashing, you will need to fold the pan’s edge by 90 degrees. Apply the siding over a perpendicular fold. You may also cut and install a counter flashing detail if working near a wall makes the installation of sidewall flashing difficult.
For skylight flashing, you will need to fabricate a sidewall flashing into roof pans. However, you have to stop the pans a few centimetres over the skylight. You will also need to install a cleat on butyl so that the head flashing can extend beyond the edge of the skylight toward the roof pan. The upper portion of the head flashing is then hemmed.
