Roofing in Mohammed Bin Zayed City

Two separate ones: a manufacturer warranty on materials (often 20-50 years, sometimes conditional on certified installation) and the contractor's own workmanship warranty (5-10 years is respectable). Get both in writing and understand what voids them — foot traffic, unventilated attics and pressure washing are common exclusions.

Tear-off and disposal, underlayment spec, flashing replacement (not reuse), ridge and valley details, a unit price for replacing rotten decking discovered mid-job, scaffolding or edge protection, and cleanup with a magnetic nail sweep. A quote missing the deck-repair unit price is the classic setup for large mid-job extras.

Dry, settled weather — and before your region's storm or rainy season, not after it starts. Roofers book out weeks or months ahead of peak season, so schedule inspections early; shoulder-season slots are often cheaper and easier to get.

Sometimes — an overlay saves tear-off cost but hides deck problems, adds weight, and often shortens the new roof's life and warranty. Many codes and manufacturers limit roofs to two layers. Tear-off costs more upfront and is usually the better long-term decision; get both options priced.

Membrane waterproofing typically runs AED 25-80 per m², so a 200 m² villa roof lands around AED 5,000-18,000 depending on system and prep. Combined insulation-plus-waterproofing packages run AED 8,000-30,000 and reduce summer cooling loads.

Because rain is concentrated into a few December-February events that find every failed joint at once, after summer heat has aged the membrane all year. Book inspection and repairs in autumn — waterproofing firms are overwhelmed the week after the first big rain.
