A leaking roof rarely fixes itself, and patching the wrong spot wastes money. The key is finding the true source — water often travels far from where it finally drips. Here are the seven causes we see most across Doha and Qatar.
1. Failed or aged waterproofing membrane. Old bitumen or coatings crack and lose elasticity under UV and heat. Fix: overlay with a UV-stable SR Coat membrane after preparation.
2. AC condensate & drainage. Constant condensate water and blocked outlets cause ponding that seeps through hairline cracks. Fix: correct drainage + seamless re-coating.
3. Cracked screed or concrete. Thermal movement opens cracks. Fix: crack treatment + a crack-bridging membrane like SR Coat PU.
4. Pipe & duct penetrations. The most common leak points. Fix: detailing with reinforcement mesh and SR Quikseal.
5. Parapet & upstand junctions. Where the roof meets walls is often under-treated. Fix: reinforced upstand waterproofing.
6. Water-tank overflow. Roof tanks overflowing onto the slab. Fix: tank waterproofing + overflow correction.
7. Gutters & metal roofs. Corroded seams and gutters on metal roofs. Fix: moisture-tolerant SR Coat MTX over seams and gutters.
Sealing the spot where water appears rarely works, because water enters elsewhere and travels. A proper survey finds the entry point — that's why our diagnosis is free.
We'll find the real cause and fix it with the right system. Book a free leak survey or message us on WhatsApp for an emergency repair.
Many roof leaks aren't from rain — they come from AC condensate, water-tank overflow, failed old membranes, cracked screeds, or blocked drainage that lets water pond and find cracks.
Often, yes. Many SR Coat systems bond over aged bitumen, tiles and existing membranes, so we can overlay and re-waterproof without full demolition in many cases.
Emergency repairs with SR Quikseal can be done immediately, even on damp surfaces. A full re-waterproofing is scheduled after a survey and typically completed in a few days depending on area.
Our Qatar-based engineers will inspect, diagnose and recommend the right system — in writing, with no obligation.
