Roof Leak Repair in Davao City
We find and fix roof leaks on houses across Davao City — rusted tekscrews and washers, cracked sealant at laps and flashings, corroded gutters, holes in yero and long-span sheets, and the ceiling damage they leave behind. An inspection with photos costs ₱800–₱1,500 and is waived when you proceed; most leaks are fixed for ₱1,500–₱8,000 depending on how many points and sheets are involved, with full sheet replacement and waterproofing quoted per area after the inspection.
Davao roofs leak in a predictable way. The metal sheet itself rarely fails; what fails is everything that holds it together — screws whose rubber washers perished years ago, sealant that cracked in the sun, a lap that lifted in one strong wind, a gutter that rusted through at the joint. Water finds the smallest of these and shows up as a brown ring on the ceiling somewhere else entirely, which is why the “fix” of smearing sealant where the drip is so often fails. Finding the actual entry point is the job.
Common causes on Davao roofs
On galvanised (GI) and pre-painted long-span roofs the usual suspects are, in order: rubber washers on tekscrews that have hardened and cracked, letting water in at every screw along a line; end laps and side laps that were never sealed or whose sealant has failed; flashing at walls, chimneys and roof-to-wall junctions that was made from a bent sheet and a prayer; ridge caps loosened by wind; and gutters — rusted at the joints, sagging so water pools, or simply full of leaves so rain overflows behind the fascia and into the ceiling. Older houses add rusted-through sheets, usually starting at the eaves where moisture sits, and roofs with too few purlins that flex and open the laps.
Concrete roof decks and balconies are a different problem: hairline cracks and failed waterproofing membranes that let water into the slab. Those need proper waterproofing over the whole surface rather than a patch, and we quote it per square metre after seeing it. The cheapest time to do any of this is before the rains: our gutter cleaning service is often where a roof problem is first spotted, and a September inspection is cheaper than a December ceiling.
How we find the leak before we fix it
A leak repair without a proper inspection is a guess with a ladder. The sequence:
- 1
Inside first
Ceiling stains, drip locations and the attic or ceiling space are checked and photographed to narrow the entry area — water usually travels along a purlin or sheet rib before it drops.
- 2
On the roof
Every screw line, lap, ridge cap, flashing, vent, gutter joint and downspout in the suspect area is inspected. Where the source is not obvious we run a hose test, one section at a time, with someone watching inside.
- 3
Written scope and price
You receive photos of each defect with a price per item — re-screw and seal, replace a flashing, replace a sheet, replace a gutter run — and choose what to do now and what can wait.

Repair and rain check
Work done with the right fasteners and sealants for metal roofing, debris cleared, gutters flowing. After the next heavy rain we ask you to confirm; if the same leak returns within the warranty period, we come back at no cost.

Frequently asked questions
Magkano ang pagpapaayos ng tumutulong bubong sa Davao?
In 2026 a typical leak — a few failed screws and a lap or flashing — costs ₱1,500–₱3,500 to find and fix. Re-screwing and sealing a whole roof runs ₱150–₱400 per sheet, sheet replacement ₱1,500–₱3,500 per sheet plus the sheet, gutter replacement ₱600–₱1,200 per metre.
Can you find the leak if it only happens in heavy rain?
Yes — that pattern usually means overflowing gutters, a lap that only takes water when wind drives it, or a flashing that fills up. We inspect for those specifically and use a hose test when the source is not visible.
Should I just have the whole roof re-screwed?
On a roof more than eight to ten years old with the original screws, often yes: it is cheap per sheet, it fixes the leaks you have not found yet, and it is faster than chasing them one by one. We tell you after the inspection whether that or a targeted repair makes sense.
Do you repair ceilings and repaint after the leak?
Ceiling board replacement and finishing yes, as part of the same job. Repainting a whole ceiling we arrange with a painting partner and quote separately, once the roof has been through a rain and is confirmed dry.
