Purlin Replacement in the UAE for Rusted and Damaged Roof Steel
Purlin replacement in the UAE is usually needed for one reason: water. Purlins are the horizontal steel members that span between the main frames and carry the roof sheets. When a roof leaks for long enough, or condensation collects under the sheets, the purlins corrode. Screws lose their grip, sheets start to lift in the wind, and the roof becomes unsafe to walk on.
Leak Lock Insulation Contracting repairs and replaces roof purlins on warehouses, factories, workshops and car park structures. Because we fix leaks as well as steel, we deal with the cause and the damage together. Building owners, facility managers and contractors call us when an inspection finds rusted purlins, or when roof sheets are being replaced and the steel below turns out to be weak.
Signs Your Roof Purlins Need Attention
For example, clients contact us for one or more of the following reasons.
- Flaking rust: steel is scaling or has lost thickness when viewed from below.
- Sagging roof lines: sheets dip between the main frames.
- Screws that will not tighten: fixings spin because the steel behind has thinned.
- Sheets lifting in wind: movement or noise from the roof in strong gusts.
- Bent members: purlins twisted by impact, overloading or storm damage.
- Long-term leaks: water has run along the same steel for seasons.

Our Purlin Replacement Process
Because every site is different, we adapt these steps to your purlin replacement project.
- Structural InspectionBefore anything else, we check purlins from below and above and mark the members to replace.
- Measurement & FabricationThen, section sizes and lengths are recorded and new purlins are prepared.
- Safe Access & Sheet RemovalAfter that, the area is secured and roof sheets are lifted in small sections.
- Purlin ReplacementAs soon as that is done, old steel is removed and new purlins are bolted or welded into place.
- Refix, Seal & HandoverFinally, sheets are refixed, laps and screws sealed, and the roof is inspected.
Materials & Methods
New purlins are matched to the existing section size and spacing so that the roof sheets and fixings line up. Steel is protected against corrosion before it is installed. Where sheets are refixed, new fasteners are used and the laps and screw lines are sealed with EPDM membrane.
In short, the work includes the following.
- Steel purlins matched to the existing section
- New cleats, bolts and sag rods where required
- Corrosion protection on new steel
- New roof fixings and sealed laps

Purlin Replacement FAQs
Questions about roof purlin repair in Dubai and steel purlin installation. Also, you can call us with any other question.
A purlin is a horizontal steel member that runs along the roof between the main frames. The roof sheets are screwed to the purlins, so they carry the weight of the sheets and resist wind uplift.
If corrosion is light and local, the purlin can be cleaned, treated and sometimes strengthened. Where the steel has lost significant thickness, replacement is the safe option. We advise after inspecting it.
Usually the sheets over the affected purlin are lifted to give access and then refixed. If the sheets are also damaged, it is the right time to replace them.
It may not be. Weak purlins and loose fixings make a roof unpredictable. Keep people off the area until it has been inspected.
Yes. Replacing steel without stopping the water only delays the same problem, so sealing the roof above is part of our scope.
