Roof Screws Waterproofing for Leaking Fixings
Roof screws waterproofing addresses the smallest and most numerous leak points on a metal roof. Every sheet is fixed through its surface with self-drilling screws, each relying on a small rubber washer. Under UAE sun those washers harden and crack within a few years. Thermal movement then elongates the holes, screws back out, and water runs straight down the thread.
Leak Lock Insulation Contracting tightens, replaces and seals roof fixings across whole roofs or along the affected lines. The service is for warehouse and factory owners and facility managers who see scattered drips across the building in rain, without one obvious source.
Signs Your Roof Screws Are Leaking
For example, clients contact us for one or more of the following reasons.
- Scattered drips: many small leaks along the lines of the purlins.
- Rust rings: corrosion spreading from screw heads.
- Perished washers: rubber that is cracked, flattened or missing.
- Raised screws: fixings that have backed out of the sheet.
- Enlarged holes: sheets moving around the fixings.
- Missing screws: open holes left after earlier works.

Our Screw Waterproofing Process
Because every site is different, we adapt these steps to your roof screw waterproofing project.
- InspectionBefore anything else, fixing lines are checked for loose, rusted and missing screws.
- Fixing RepairsThen, screws are tightened or replaced as required.
- CleaningAfter that, dust and rust are cleaned from the fixing lines.
- Membrane SealingAs soon as that is done, EPDM strips are bonded over the screw lines.
- CheckFinally, sealed lines are inspected and water tested where possible.
Materials & Methods
After the fixings themselves are made sound, the screw lines are covered with EPDM membrane strips and bonding adhesive. Covering the line seals every screw head at once and is more durable than dabbing sealant on individual screws, which cracks again as the roof moves.
In short, the work includes the following.
- New roofing screws with sealing washers
- EPDM membrane strips over fixing lines
- Bonding adhesive for metal sheets
- Rust treatment around corroded fixings

Roof Screw Waterproofing FAQs
Questions about leaking roof screws. Also, you can call us with any other question.
The rubber washer under each screw head hardens in the heat and cracks. Daily expansion of the sheets also loosens the screw and enlarges its hole.
It works for a short time. Sealant on a screw head cracks as the sheet moves. Covering the fixing line with a flexible membrane lasts longer.
No. Sound screws are tightened, and only rusted, stripped or missing ones are replaced.
Yes. Screw lines and sheet laps are usually treated together as part of metal roof waterproofing.
