Bituminous membrane repair in Gueliz is one of the jobs we carry out most often in the area. Materials rated for the Marrakech climate, a tidy site, deadlines kept: free survey, written quote within 24 hours, ten-year warranty on the works.
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 repair in Gueliz: the job
Bituminous membrane repair in Gueliz starts with substrate preparation: cleaning, bonding primer, then membrane application matched to how the roof will be used. Cutting out the blistered area, drying, patch welding with reinforcement: we repair the leak where it is, with a durable joint to the existing membrane. The indicative cost is from 1,200 DH; after the free survey, the price is fixed in writing and locked.

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.
In Gueliz, as everywhere in Marrakech, waterproofing is the poor relation of recent construction: bituminous membrane repair is the safest way to put the roof right before a small leak becomes a major damage.

James H. · GuelizFrequently asked questions: Bituminous membrane repair in Gueliz
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.
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.
