The flat roof is the signature of Marrakech — and its weak point. Concentrated rain from November to March, 45 °C summers that bake the membranes: terrace waterproofing here must be designed for this climate, not for a European one. We carry out complete waterproofing of the flat roofs of riads, villas and apartment buildings: diagnosis, substrate preparation, membrane or resin, parapet upturns, final water test. Written warranty of up to 10 years.
Rainy season Nov–Mar: The Marrakech rainy season runs from November to March: that is when every tired terrace reveals itself. An ignored leak costs up to 10 times the price of waterproofing — damaged beams, lifted tadelakt, mould, repainting — and cuts the value of the property. The right time to waterproof is before the first heavy rain, not after it.

What our clients say
“Our riad terrace was redone respecting the Medina’s constraints: materials carried in by hand, parapets rebuilt, zellige preserved. True specialist work.”
Anna S. · Marrakech“Serious people: protection everywhere, deadlines kept, and the terrace handed back cleaner than they found it.”
Sophie M. · Marrakech“For flat roof waterproofing they recommended the simplest solution, not the most expensive one. You can tell they are technicians, not salesmen.”
Leïla H. · MarrakechFrequently asked questions: Flat roof waterproofing
Yes: earthen and timber substrates, pedestrian alley access, ADER/UNESCO constraints. We use light, flame-free systems and hand-carry materials, and we know the rules for preserving the roofline.
Before handover, we flood or hose the terrace and check the flow to every drain and the absence of leaks below. You receive the photos and the written warranty.
Yes, in the vast majority of cases: we work zone by zone, without heavy demolition when the substrate allows, and we protect stairwells and the rooms below.
Expect 150–420 DH/m² depending on the system: liquid membrane 140–220 DH/m², bituminous 180–350 DH/m², traffic resin 220–380 DH/m². An 80 m² terrace is usually treated for 15,000–30,000 DH: the exact figure comes after the free survey.
