Looking for a specialist for inverted roof insulation 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.
Inverted roof insulation in Gueliz: the job
A top floor you can live in during summer without the AC flat out: inverted roof insulation in Gueliz treats the heat where it enters — through the roof. XPS laid over the membrane, protected by gravel or slabs: the waterproofing stays at a stable temperature and lasts years longer. Our Marrakech favourite. The indicative spend is 220–380 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 inverted roof insulation in Gueliz we bring the same care as on our central Marrakech sites: certified materials, proper application and a clean handover, every time.

Frequently asked questions: Inverted roof insulation in Gueliz
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.
No: everything happens on the roof, within a limited thickness (6–10 cm). In the Medina it is an ADER-compatible solution, as nothing is visible from the street.
From 120 to 300 DH/m² depending on the system: warm roof 150–300 DH/m², inverted roof 220–380 DH/m², inside insulation 90–180 DH/m². Combined with waterproofing, expect 280–480 DH/m² — less than two separate jobs.
