Roofing in Seri Kembangan

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.

Common leak repairs run RM300-RM2,500 depending on access and cause, while re-roofing runs roughly RM15-RM45 per square foot. A full re-roof of a terrace or semi-D typically lands at RM25,000-RM85,000.

Metal deck is lighter, faster to install and cheaper, but noisier in heavy rain and hotter without insulation; concrete tile costs more upfront and needs stronger structure but insulates and lasts longer. For monsoon rain, the installation quality of flashings and laps matters more than the covering choice.
