What Is A Roof Purlin And Why Do I Need One?

A roof purlin is a horizontal beam that runs along the length of a roof and supports the rafters.

What Is A Roof Purlin And Why Do I Need One?
If you’re planning on building a roof, then you’ll need to know about purlins. Purlins are horizontal beams that support the weight of the roof. They are typically made from wood, but can also be made from metal.

Purlins are installed on the top of the rafters. They provide support for the roofing material and help to distribute the weight of the roof evenly. Purlins also help to stiffen the rafters, which can help to prevent the roof from sagging.

Purlins are an important part of the roofing system and should not be overlooked. If you’re not sure whether or not your roof needs purlins, then it’s best to consult with a professional.

How Do I Properly Support A Roof Purlin?

The roof purlin should be properly supported by a rafter or beam.

Cut two 2×4’s to the length you need to span the area from the bottom of the purlin to the top of the wall plate. Place the 2×4’s on either side of the purlin so that they are flush with the purlin’s top edge.

In most cases, you will also need to toenail the 2×4’s into the wall plate and/or the end purlin. To do this, drive 6d nails at an angle through the 2×4 and into the wall plate and/or purlin.

You can also use hurricane ties to secure the 2×4’s to the purlin. Hurricane ties are special metal plates with nails that are driven into the wood.

Here is an example of a hurricane tie:
