What Happens When Purlins Are Poorly Installed?
A problem with purlins can affect the entire roof.
For example:
Poor purlin spacing → inadequate sheet support → excessive movement → stress on fixings → potential leakage or damage
This shows why a roofing problem that appears to involve the sheets can sometimes originate underneath them.
Signs That May Require Inspection
A homeowner may notice:
Uneven or sagging roof surfaces
Excessive movement of roofing sheets
Loose or damaged fasteners
Unusual roof noises during strong winds
Visible deformation of structural members
These signs do not automatically mean the purlins are defective, but they justify professional inspection.

Purlins and Roofing Sheet Thickness
Roofing sheet thickness and purlin spacing should be considered together.
A roofing sheet is not automatically suitable simply because it is thicker or more expensive.
The entire roofing system needs to be designed so that the sheets, purlins and trusses work together.
For this reason, installers should follow the manufacturer's recommendations and the structural design rather than relying on a general rule that applies to every roof.
Timber Purlins
Timber has traditionally been used in many roof structures.
Advantages can include:
Availability
Ease of cutting and installation
Familiarity among local builders
Relatively simple connections
However, timber must be appropriately selected and protected.
Problems such as excessive moisture, decay, insect attack or inadequate structural sizing can compromise its performance.
Steel Purlins
Steel purlins are also widely used.
They can offer:
High strength-to-weight ratios
Dimensional consistency
Resistance to some forms of biological deterioration
Compatibility with modern steel roof systems
However, steel components still require appropriate sizing, connections and protection against corrosion where necessary.

Where Are Purlins Located?
A simplified roof structure can be understood as:
Roofing sheets → Purlins → Trusses → Walls → Foundation
The roofing sheets sit on or are fixed to the purlins.
The purlins transfer their loads to the trusses, while the trusses transfer the loads to the supporting walls or other structural supports.
This creates a continuous load path from the roof down into the building.

What Is a Purlin?
A purlin is a horizontal structural member installed across the roof trusses.
It provides support for the roofing sheets and helps distribute loads across the roof structure.
Depending on the design, purlins can be made from:
Timber
Steel
Cold-formed steel sections
Other suitable structural materials
The appropriate material and size depend on the structural design of the roof.
