End Laps (Horizontal Joints)

About ETCE
A Dammam contractor focused on one job: dry industrial metal roofs
Eastern Technical Contracting & Establishment rehabilitates metal roofs on warehouses, factories and hangars across Saudi Arabia. Rather than recoating whole roofs, our crews treat every lap, fastener, gutter and penetration with EPDM, so buildings stay dry through Eastern Province humidity and Riyadh heat alike.
To give every industrial roof owner in the Kingdom a leak-free roof they can verify: surveyed, photographed, treated point by point and warranted.
To be the contractor Saudi facility managers call first for metal roofs, known for honest surveys, itemised quotations and repairs that last summer after summer.
Survey before we quote. Treat the cause, not the stain. Work safely at height. Keep your site running while we work. Stand behind every warranty we issue.
Why Saudi metal roofs leak
It is rarely the sheet. It is the thousands of joints holding it together.
A typical warehouse roof in the Kingdom carries thousands of fasteners, laps and penetrations. Summer surface heat hardens washers and sealants, shamal winds push dust and rain sideways into the laps, and on the coast salt air starts rust at every cut edge. Each weak point becomes a path for water. A blanket coating hides the symptoms for a season; sealing each point removes the cause.
How ETCE works
Survey, seal, then stand behind it.
STEP 01
Free roof survey
An engineer walks your roof, traces where water really enters and sends a written report with photos of every failure point.
STEP 02
Point-by-point EPDM sealing
Laps, fasteners, gutters, skylights and penetrations are treated one by one with 1.2 mm EPDM and Promax Bonding Adhesive while your site keeps working.
STEP 03
Tested, documented, warranted
Treated areas can be water-tested before handover, and the system carries up to a 15-year warranty with a 24–48 hour after-sales response.
EPDM vs coatings
Why Saudi facility managers are switching from bitumen coatings to EPDM
| Bitumen / acrylic coating | ETCE EPDM system | |
|---|---|---|
| Approach | Covers the whole surface | Targets each leak path |
| Summer roof heat | Softens, then cracks and peels | Stays flexible and UV-stable |
| Foot traffic for maintenance | Easily damaged | Walkable once installed |
| Expected life | Recoat every few summers | Up to 15-year warranty |

Eave, Valley & Box Gutters
Every drop that lands on a metal roof ends up in a gutter, which makes eave, valley and box gutters the hardest-working part of the whole roof.

Skylights
Skylights bring daylight into warehouses and factories, but on many metal roofs they are also the first thing to start leaking.

Turbine Ventilators & Fan Units
Turbine ventilators and powered roof fans keep hot air moving out of warehouses and factories, but they never stop moving themselves.

Pipe & Cable Penetrations
AC refrigerant lines, condensate pipes, electrical conduits and solar PV cables all need a way through the roof, and each hole is a potential leak.

FAQ
Metal-roof waterproofing: your questions answered
How long does metal-roof EPDM waterproofing last?
Correctly installed EPDM typically lasts well beyond 20 years on Saudi roofs because it does not harden or crack in summer heat. ETCE issues a warranty of up to 15 years on its EPDM systems.
Will the work disrupt our warehouse or factory operations?
In almost every case, no. Our crews work from the roof surface one zone at a time, so production, storage and loading carry on underneath.
What does the free roof survey include?
An engineer walks the roof, traces where water is actually entering, and gives you a written report with photographs of each failure point and a detailed, itemised quotation. There is no charge and no obligation.
Which cities in Saudi Arabia do you cover?
ETCE's head office is in Dammam. We cover Dammam, Al Khobar, Dhahran, Jubail and the wider Eastern Province, and mobilise to Riyadh, Jeddah and Bahrain for surveys and projects.
How fast can you inspect after I enquire?
Expect a call from an ETCE engineer within 24 hours of your enquiry to book the free survey. Sites in Dammam, Al Khobar and Dhahran can usually be visited within a couple of working days.
Do you work at height safely? What HSE do you follow?
Yes. Every crew is trained for working at height and uses full PPE, lifelines and proper access equipment, following your site's HSE rules as well as our own.
What is covered by the warranty?
It covers the EPDM waterproofing at every point we treated, for up to 15 years, backed by after-sales teams that respond within 24 to 48 hours.
How do I choose a waterproofing company in Saudi Arabia?
Ask any waterproofing company for a site survey with photos of each leak point, an itemised quotation, a written warranty and examples of similar buildings they have treated. ETCE provides the survey, quotation and project references free, and a written warranty with every EPDM system.
Can we see similar projects before we decide?
Yes. Our projects page shows documented work for Zamil Plastics, ATCO, Alfa Laval, Guardian Industries, Kanoo, Lulu and others, each with site photos and the exact failure points treated.
