Frequently Asked Questions
Which waterproofing for Moroccan terrace roof?
Moroccan climate (intense UV + 30°C day/night thermal swing) requires: SBS double-layer minimum (110-160 MAD/m²), 25 years with mineral self-protection (slate granules). Accessible/parking terrace: SBS + mechanical protection (5 cm concrete slab). Modern roof: PVC/TPO Sika Sarnafil (35-50 years, 160-220 MAD/m²). Avoid 1-layer felt in south (UV destroys in 8-12 years).
Why do Moroccan terraces leak so often?
Main causes: 1) Sloppy install by non-pro. 2) Insufficient slope (<1.5%, water pools). 3) Glued waterproofing without mechanical protection = puncture from foot traffic. 4) Poor joints around drains/chimneys. 5) Unplanned aging (renew at 15 years). Waterproofing = critical: 0% savings justified. Demand 10-year decennial warranty + 5+ year photo references.
Liquid or traditional membrane?
Liquid (Sika SikaTop Seal, Mapei Mapelastic): seamless, follows all shapes (walls, corners, pipe penetrations), ideal bathrooms and complex shapes. Brush/roller application, 2 coats. 15-25 year life. Traditional membrane (SBS): reference for large flat areas (terraces), cheaper on big m². 20-25 years. Combine: liquid everywhere except large flat surfaces.
Cost to renovate 50 m² terrace waterproofing?
Steps: 1) Existing demo + disposal: 30-50 MAD/m² × 50 = 1,500-2,500. 2) Substrate prep + slope screed: 4,500. 3) SBS double-layer: 6,500. 4) Protection (5 cm slab if accessible): 5,500. 5) Joints + drains + finishes: 1,500-3,000. Standard total: 19,500-22,000 MAD (~400-440 MAD/m²). Without protection: 12,000-15,000 (~250-300/m²).
Is waterproofing covered by insurance?
Decennial warranty (10 years, Moroccan Civil Code article 769 mandatory): covers waterproofing defects affecting solidity or destination use. Conditional on declared insured contractor (RC + decennial). Reno on existing: new decennial starts at handover. Keep: detailed invoice + handover record + insurance attestation. Without: no compensation. Demand valid insurance BEFORE signing quote.
