Targa: 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 Targa: the job
Membrane over old roofing in Targa 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.
Trusted in Targa
“Water came through the living-room ceiling every time it rained. Survey on Thursday, quote the next day, work finished in four days. Not a drop since.”
Charlotte V. · Targa“For membrane over old roofing I had three quotes: theirs wasn’t the cheapest but it was the only one itemised line by line. Price respected to the dirham.”
James H. · Targa“They re-waterproofed without demolishing: no rubble in the stairwell, a tidy site every evening. The neighbours noticed nothing.”
Robert N. · TargaThe Targa context
Targa is the rising residential district: recent developments, new villas and small residences are springing up along the Fès road. The local paradox: recent terraces already failing, because the waterproofing was done fast and cheap during construction — a single bitumen layer, parapet upturns too low, undersized drains. Owners often call us within the first five years: leaks in the living-room ceiling, damp stains in bedrooms, water ponding in the middle of the terrace. We rebuild these roofs with warranted systems, correcting the falls and raising the upturns to the proper height.
People who call us from Targa 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.

Frequently asked questions: Membrane over old roofing in Targa
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.
Single layer 180–260 DH/m², double layer 260–350 DH/m², self-adhesive 200–320 DH/m², upturns 100–170 DH/m. For a 100 m² terrace, expect roughly 22,000–35,000 DH double-layered, confirmed by quote after the free survey.
