Metal roofing is a great option for your home that can bring a modern look and increase energy efficiency. It's cost-effective and one of the most environmentally friendly options. However, they'll need some kind of support structure to keep from bending or warping over time. Of course, one of the main benefits of using purlins is if you have existing shingles on your roof, and you want to install metal roofing over top of existing shingles, the use of purlins installed on top of the existing shingles has several advantages.

One way to support a metal roof is with wood purlins. These function much like rafters, except that they stretch between each angled part of the roof rather than along it.

Here are some of the benefits of installing purlins in your next build.

Purlins Provide More Support and Structure

The main reason to use something like wood purlins for your metal roofing is that they provide both support and stabilization.

If you were to install a roof without purlins, you'd have to build a deck for the roof. This can result in a lot of extra time and materials. Instead, purlins can be used much more easily, and they provide a unique appearance to your interior.

In addition, purlins tie the rafters together so they can withstand heavier winds and weather conditions. You don't have to worry about them flying off or sagging down.

Creates More Energy Efficient Metal Roofing

Another of the uses for purlins for metal roofing is that they're energy efficient. They create a flat surface to install the roof on and airspace to allow for better circulation. Your home will have less heat due to the metal conducting it into the airspace underneath your ceiling.

What this means is that your air conditioning unit won't have to work as hard to keep the interior cool. It also has more space to displace all of the hot air that may accumulate throughout the day.

You can improve the energy efficiency of your home with things like heat-repelling accessories. For example, there's a radiant barrier and synthetic underlayment that you can combine for more heat resistance. You can also choose a more energy-efficient finish for your roof, such as something with a reflective coat.

Improve Your Roof Renovation Project

Wood purlins are highly recommended if you're working with metal roofing. It provides a frame for it to rest on, and it can help keep your home cooler throughout the warmer months. However, it can be difficult to know if it's the best option vs other types of roof support.
