Roofing in Selangor

Yes — replacing one slope or section is common after localised storm damage and costs far less than a full reroof. The trade-offs are colour mismatch with weathered existing material and tying new work into old underlayment. It makes most sense when the rest of the roof has meaningful life left.

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.

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.

A straightforward single-family roof takes 1-3 days for asphalt shingles or metal sheeting, and up to 1-2 weeks for tile, slate or complex multi-plane roofs. Weather delays are normal — a competent crew will never strip more roof than they can waterproof the same day.

It scales with roof area, pitch, number of storeys, access, and material. Basic asphalt shingle or concrete tile sits at the bottom of the range; metal, slate and clay cost two to four times more. Tear-off of the old covering, disposal, scaffolding or edge protection, and hidden deck repairs are the lines that move a quote most — make sure all four are priced before comparing.

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.
