Roofing in Bintulu

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.

Yes, over time — moss holds moisture against the surface, lifts tile and shingle edges, and accelerates frost damage. Have it removed by soft washing or manual scraping, never high-pressure washing, which strips granules and forces water under the covering. Zinc or copper strips slow regrowth.

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.

Typically 10-30%, or enough to cover ordered materials, with the balance staged against progress and completion. Never pay in full upfront, and be wary of anyone who can start 'tomorrow' if you pay cash today — good roofers have lead times.

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.
