Looking for a specialist for terrace thermal audit 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.

Terrace thermal audit in Gueliz: the job

Thermal camera, surface measurements, expected-gain calculation: you know exactly what insulation will save you before spending a dirham. The indicative cost is from 1,500 DH; after the free survey, the price is fixed in writing and locked.

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.”

William G. · Gueliz

“The terrace had been ponding for years: they rebuilt the falls, changed the drains and laid a proper membrane. No more ceiling stains.”

Rachid T. · Gueliz

“We called them for terrace thermal audit, then called them back for my parents’ roof. Nothing more to add.”

Mark T. · Gueliz

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.

People who call us from Gueliz for terrace thermal audit often already have two or three quotes: ours stands out because it is written line by line and the price never moves afterwards.

Frequently asked questions: Terrace thermal audit 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.

Before the rainy season, make your terrace safe

From November to March, an ignored leak costs up to 10 times the price of waterproofing. WhatsApp or form: we can be in Gueliz within days for a free diagnosis.
