Testimonials ## What PJ homeowners say ★★★★★ 5.0 Google rating from PJ & Selangor ★★★★★ "Two other contractors patched and the leak came back. Roof Builder Resources actually traced it to a cracked valley gutter and fixed the real problem. No more leaks since." Wei Liang T. Kota Damansara · Roof Leak Repair ★★★★★ "Stubborn flat-roof slab leak above the bathroom. They used PU injection without hacking up the tiles. Clean job, done in a day, ponding test confirmed sealed." Suhana A. Damansara Utama · Waterproofing ★★★★★ "Booked a site inspection for our ageing terrace roof. The report was detailed and honest — they recommended recoating instead of a full replacement, saving us a lot." Daniel C.

Yes. We provide a free on-site inspection across Petaling Jaya and most of Selangor, then give you a project-based quote after we've traced the actual problem. Estimates are only given after we've seen the roof. How much does roof leak repair cost? Roof leak repair is priced per project, depending on the leak source, severity, and access. Because the real source often differs from where the stain shows, we quote only after a site inspection so the price reflects the actual fix, not a guess. What is no-hack PU injection waterproofing? No-hack PU injection seals cracks in concrete slabs, flat roofs, and wet areas by injecting polyurethane under pressure, without demolishing tiles or floors. It's a clean, fast way to stop slab and bathroom leaks at the source. How quickly can you respond after a leak? We aim to schedule same-day or next-day site visits across Petaling Jaya, prioritising active leaks after heavy rain. Being based in Sunway Giza, Kota Damansara lets us reach most PJ areas quickly. Do I need a full roof replacement or just a repair? Most roofs only need a targeted repair or recoating, not a full replacement. We replace a roof only when damage is widespread, leaks keep recurring, or the structure is failing, and we'll tell you honestly which one your roof needs.
