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.

Trusted in 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.”
Robert N. · 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.”
Emma R. · Gueliz“For warm roof (insulation under membrane) I had three quotes: theirs wasn’t the cheapest but it was the only one itemised line by line. Price respected to the dirham.”
Claire D. · GuelizThe 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.
In Gueliz, jobs like warm roof (insulation under membrane) are among the most requested: with summers above 45 °C and rain concentrated in winter, a well-laid membrane and correct falls make the difference between a terrace that lasts and one that has to be redone.
Frequently asked questions: Warm roof (insulation under membrane) in Gueliz
Typically 5 to 8 °C less in the rooms under the roof, measured in summer. The air conditioning kicks in less often and nights become bearable without running it all night.
From the roof, whenever possible: you treat the slab where the heat enters and protect the waterproofing at the same time. Ceiling insulation remains useful when the terrace can’t be redone (constraints, budget).
Warm roof: insulation under the membrane. Inverted roof: XPS boards laid over the membrane, which then stays at a stable temperature and lasts longer. In Marrakech we strongly favour the inverted build-up for that reason.
Yes, if the existing membrane is sound: we lay the XPS as an inverted roof directly over it. If the waterproofing is end-of-life, combining both is the most economical option.
