Amizmiz: we carry out membrane over old roofing with waterproofing systems proven under the Marrakech climate — extreme summer heat, concentrated rain from November to March. You pay only after reading the quote: free, written and without obligation.
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 Amizmiz: the job
Membrane over old roofing in Amizmiz starts with substrate preparation: cleaning, bonding primer, then membrane application matched to how the roof will be used. 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 cost is 200–300 DH/m²; after the free survey, the price is fixed in writing and locked.
The Amizmiz context
Amizmiz and its douars were hit by the September 2023 earthquake: reconstruction is under way, and with it a new requirement — rebuilding roofs that no longer leak. On rebuilt or strengthened houses, roof waterproofing is the weak point of jobs done in a hurry: slabs poured fast, no upturns, improvised drainage. We work in Amizmiz with solutions suited to earthen housing and small recent slabs: light membranes, careful upturns, corrected falls, and pricing designed for reconstruction budgets. Every watertight roof is a house that gets through the Atlas winter without damage.
For membrane over old roofing in Amizmiz we bring the same care as on our central Marrakech sites: certified materials, proper application and a clean handover, every time.

Frequently asked questions: Membrane over old roofing in Amizmiz
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.
