Looking for a specialist for bituminous membrane in Gueliz? Flat roofs, terraces and waterproofing are all we do, in Marrakech and across the Haouz. Free survey, written quote within 24 hours and a firm price before the first roller stroke. Not a general builder: a flat-roof specialist.
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.
Bituminous membrane in Gueliz: the service
The bituminous membrane is the most common flat-roof system in Morocco — and the most poorly applied. One layer instead of two, 5 cm upturns, sloppy torching: that is why so many Marrakech terraces leak before their tenth year. We apply it the way it should be: prepared substrate, primer, single or double layer according to use, 15–20 cm upturns, sun-adapted protection. And we warrant the result in writing.
We work in Gueliz every week: we know the local building types and we already know where to look for bituminous membrane — door thresholds, parapets, roof drains.
The roofing context in Gueliz
Gueliz, the new town laid out in the Protectorate era, is dense with 1930s–70s apartment buildings: ageing concrete slabs, technical roof terraces shared between co-owners, cracked parapets and original bituminous waterproofing that has often never been replaced. This is the district of co-ownership files: who pays, when to intervene, how to coordinate the top-floor flats. We manage the whole job there, from the shared diagnosis to the report for the building manager, with flame-free systems suited to occupied buildings. Gueliz summers regularly top 45 °C: black membranes baked by the sun crack open, and the first November rain exposes every defect.

Trusted in Gueliz
“Perfect communication on WhatsApp from start to finish: I always knew what would happen the next day and who would be in my house.”
Henry W. · Gueliz“The terrace had been ponding for years: they rebuilt the falls, changed the drains and laid a proper membrane. No more ceiling stains.”
William G. · Gueliz“We called them for bituminous membrane, then called them back for my parents’ roof. Nothing more to add.”
Mark T. · GuelizFrequently asked questions: Bituminous membrane in Gueliz
Often not: if the old membrane still adheres, we lay the new layer over it after preparation. If it is blistered or detached, stripping is unavoidable — the free survey settles the question.
Not directly: it is protected with gravel, slab-on-pedestal decking or tiles. If you want to walk on the terrace with no covering, traffic resin is the right answer — we compare both in the quote.
Single layer 180–260 DH/m², double layer 260–350 DH/m², self-adhesive 200–320 DH/m², upturns 100–170 DH/m. For a 100 m² terrace, expect roughly 22,000–35,000 DH double-layered, confirmed by quote after the free survey.
Double layer, almost always: the second layer protects the first one’s welds and doubles the service life. Single layer only makes sense on non-traffic roofs on a tight budget — and we tell you so honestly at the survey.
