In manufacturing metal roofs, as we do at Metal Master Shop, one of the many things we take into account when forming the roof panels is the pitch of the roof.
Roof Pitch, defined
In a nutshell, the pitch of a roof is the steepness or the angle of the roof. It can vary a great deal, from flat to an extreme angle and everything in between.
Depending on the material you are using, your pitch will have to be adjusted.
Thatch, a very old roofing material, drains best when it is at a steep pitch.
Stone will leak if the pitch is too shallow. If it’s too steep, the stone can slide off.
Shingled roofs with a high pitch, a.k.a. very steep, are too dangerous to walk on so safety precautions have to be taken to work on it securely.
Metal Roof Pitches
The short answer here is that metal roofs can be manufactured and installed for any roof pitch, from steep to dead (flat). There are important things to consider as you go to the extremes of either range.
Water damage is a main consideration when choosing the steepness of a roof. Steeper roofs will drain the water very quickly, which will help it last longer. A flatter roof makes it so water can pool and sit longer, seeping into the joints and seams.
The safety and installation process is also a factor of roof pitch. Steep roofs will require a little more time because they are more dangerous to install. The roofing panels will also need more fasteners to hold together since gravity works on a roof just as it does on everything else.
If you are interested in calculating the pitch of your roof, you can find a lot of tools online. Here’s a good one.
Of course, as a roofer, you know all about the pitch of roofs and the different materials involved. Hopefully now you are a little more familiar with metal roof pitch concerns as well. And, as always, we are a resource if you need it!
