Roofing in Ras Al Khaimah

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.

Flashing is the metal detailing that seals joints — around chimneys, valleys, vents, skylights and wall junctions. These joints move and collect water flow, so flashing fails long before the main covering. If a roofer proposes reusing old flashing on a full replacement, push back.

Repair when damage is localised — a few slipped tiles, one flashing leak — and the roof is under about two-thirds of its expected life. Replace when leaks recur in different places, more than roughly 30% of the covering is failing, or repair quotes start approaching a third of replacement cost. A good roofer will show you photos from the roof to justify either answer.

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.
