The junction, the sheet, or the gutter
Most porch leaks are the wall flashing, not the whole roof. Most mosquito complaints are a gutter that holds water because a bracket has dropped.

|---|---|---|

2026 awning, sheet and gutter bands
Sheet replacement matches the existing polycarbonate or ACP. It is not a new roof design and it is not a GFA submission.
| Job | 2026 SGD band | Inclusions |
|---|---|---|
| Roof gutter and downpipe unchoke | S$280 to S$580 | Leaf and sludge removal, flush, and gradient bracket re-fix so water does not sit. |
| Awning, skylight or trellis wall-junction reseal | S$350 to S$680 | UV-stabilised polyurethane sealant and aluminium flashing tape at the wall junction. |
| Tempered glass skylight weather-joint reseal | S$480 to S$1,100 | Cut out failed silicone and reseal the structural glazing joint. |
| Polycarbonate or ACP roof sheet replacement, one bay | S$950 to S$3,200 | Cracked or yellowed twinwall, solid polycarbonate or aluminium composite sheet, about 4 to 15 sqm, matched to the existing bay. |
A new carport is not a sheet swap
A yellowed bay of about 4 to 15 square metres stays S$950 to S$3,200. A new pergola or a new carport is quote on inspection. URA’s porch-roof sentence is not a building price.
Awning leaks, polycarbonate sheet replacement and gutter cleaning: access and preparation
Awning leaks, polycarbonate sheet replacement and gutter cleaning is planned around the outlet that is already there. A washer, a hose, a siphon or a like-for-like tap on the same point is maintenance. Moving the waste, adding a water point, or opening a concealed riser is a PUB licensed plumber, and hacking the floor or wall for that new point is an HDB renovation permit through V On Construction.
The price moves with access, not with a slogan. An exposed fitting under a basin is a shorter visit than a concealed cistern, a ceiling tank, or a thread that has snapped inside the wall. Condo water shutdowns and HDB noisy-work hours can split the job across a slot the building allows. Parts you already bought are labour only when the thread and the seat match.

Plan Awning leaks, polycarbonate sheet replacement and gutter cleaning
Isolate the stopcock or the heater switch before any fitting is loosened.
Photograph the existing joint so the replacement can match the thread and the outlet.
Do the repair on the existing point. Do not chase a new pipe unless a licensed plumber is on the job.
Run water, check the ceiling below if the bathroom is over another room, and wipe the joint dry.

| Access | HDB | Condo | Landed |
|---|---|---|---|
| Approval | Town Council hours for noisy work. An HDB permit only if the layout or a hack changes. | MCST by-laws, a water-shutdown window, and a deposit if the by-law asks for one. | No HDB permit. A new sewer run or a structural chase is still PUB or BCA, not a handyman visit. |
| Water | Like-for-like on the existing outlet stays maintenance. | The same rule, plus the building may shut the riser for a short window. | Long runs, pumps and tanks need the plumber to see the plant, not only the tap. |
| Access | Service yard and bathroom are usually reachable the same day. | Lift booking and protection of common areas come first. | A roof, a gutter or an external pipe may need safe access before anyone climbs. |
