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.
Membrane over old roofing in Gueliz: the job
A well-laid bituminous membrane beats every patch in the world: membrane over old roofing in Gueliz with clean welds, upturns at the right height and real sun protection. When the old membrane still adheres, the new one goes over it after preparation: no stripping, no rubble and part of the cost saved. The indicative spend is 200–300 DH/m²; the final figure is written before we start and never changes.

The Gueliz context
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.
For membrane over old roofing in Gueliz we bring the same care as on our central Marrakech sites: certified materials, proper application and a clean handover, every time.

Trusted in Gueliz
“A leak in the middle of the rainy season: fast response, temporary weatherproofing then the final repair at the quoted price.”
Sophie M. · Gueliz“I was looking for an alternative to full demolition: liquid membrane and the terrace was like new in three days. I wish I had called earlier.”
Youssef B. · Gueliz“Water came through the living-room ceiling every time it rained. Survey on Thursday, quote the next day, work finished in four days. Not a drop since.”
Oliver P. · GuelizFrequently asked questions: Membrane over old roofing in Gueliz
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.
Yes, provided it is protected: slated finish, reflective paint or gravel. A bare black membrane cooks at over 70 °C on the surface and ages twice as fast — the classic mistake we correct.
We avoid open flame on timber substrates and riads: in that case, self-adhesive membrane or liquid membrane. Same waterproofing result, no fire risk and no ADER issues.
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.
