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 Medina: the job
Membrane over old roofing in Medina 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 Medina context
The Marrakech Medina is our home ground: hundreds of riads with centuries-old flat roofs built from earth, cedarwood and lime, where traditional waterproofing — rammed earth layers and tadelakt — is reaching the end of its life. Every job here must respect ADER rules and the UNESCO listing: no hauling tonnes of rubble through narrow derbs, no altering the roofline of the terraces. We use light materials compatible with pisé: flexible resins, flame-free self-adhesive membranes, parapet upturns rebuilt to standard. Leaks in the Medina are unforgiving: they rot the wooden beams, swell the earthen walls and lift the tadelakt off bedroom walls.
People who call us from Medina for membrane over old roofing often already have two or three quotes: ours stands out because it is written line by line and the price never moves afterwards.

Sophie M. · MedinaFrequently asked questions: Membrane over old roofing in Medina
Double layer, almost always: the second layer protects the first one’s welds and doubles the service life. Single layer only makes sense on non-traffic roofs on a tight budget — and we tell you so honestly at the survey.
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.
