Roof Maintenance Services

Waterproofing treatment on a pitched tiled roof in Singapore

Roof maintenance

Most roof leaks start small. A tile slips in a storm, or leaves pile up in a valley gutter. Caught on a routine visit, either one takes minutes to fix. Missed for a whole monsoon season, the same defect can leave a brown stain across the ceiling below.

Roof Doctors provides roof maintenance services for homes and commercial buildings across Singapore. On each visit our crew works through a 20+ point checklist and fixes the small items on the spot. Afterwards you get a photo report of everything we found. The first inspection is free, and every job carries a workmanship warranty.

Maintenance plans

Roof maintenance plans

How often a roof needs a visit depends mostly on its age and how exposed it is. A five-year-old tiled roof on a terrace house needs far less attention than a large metal roof over a factory. We suggest a plan after the first inspection, and you can change the frequency later.

12visits a year

Monthly

Commercial and industrial roofs where a leak would halt work

4visits a year

Quarterly

Large landed homes, condo roofs and older roofs with known weak spots

2visits a year

Bi-annual

Most homes, with a visit before each monsoon

1visit a year

Annual

Newer or recently restored roofs

We price each plan per roof after that first visit, because a porch roof and a warehouse roof are very different jobs. You get the visit fee and the scope in writing before you commit.

Preventive vs corrective maintenance

Corrective maintenance fixes a problem after it has done damage. Preventive maintenance finds the cause while the fix is still small and cheap.

Take a blocked gutter. Clearing it on a routine visit takes about half an hour. Leave it until a heavy storm and the water backs up under the roof covering and into the ceiling boards. By then the repair covers the ceiling and the paintwork as well as the gutter.

Inspection checklist

Our 20+ point roof inspection checklist

Every visit follows the same checklist. Our crew works through it in order, and you can compare one report with the next to see how the roof is ageing.

Roof covering

  • Cracked, slipped or missing tiles
  • Ridge and hip capping mortar
  • Rust and loose fixings on metal sheets
  • Condition of any existing roof coating
  • Moss, algae and lichen growth

Drainage

  • Eave gutters and valley gutters
  • Downpipes and outlets
  • Ponding on flat roofs and gutter slabs
  • Overflow points and leaf guards
  • Drainage falls after heavy rain

Waterproofing and joints

  • Waterproofing membrane on RC roofs
  • Flashing at walls and skylights
  • Sealant at joints and penetrations
  • Cracks and movement joints
  • Parapet walls and copings

Structure and interior

  • Fascia boards and eaves
  • Timber battens and trusses where accessible
  • Stains or damp patches on the ceiling below
  • Early signs of spalling concrete
  • Pipe and aircon penetrations through the roof

Visit process

What happens on a roof maintenance visit

How long a visit takes depends on the size of the roof and how easy it is to reach. The steps stay the same:

  1. Inspect the roof surface, gutters and flashing (on tiled roofs, our crew steps only where the tiles can take the weight)
  2. Check the ceilings and walls inside for stains that point to a hidden leak
  3. Clear gutters and outlets, and fix small defects such as a slipped tile or split sealant
  4. Photograph each defect before and after
  5. Send you the photo report, with a quote for any bigger works

If we find an active leak during the visit, we tell you on the spot and explain the options before any extra work starts.

Seasonal guide

Roof maintenance for Singapore’s monsoon seasons

Singapore has two monsoon seasons. The Northeast Monsoon runs from about December to early March and brings long spells of heavy rain. The Southwest Monsoon, from about June to September, brings early-morning squalls with strong gusts. Between them, the inter-monsoon months see frequent afternoon thunderstorms. Most roof leaks show up when a weak spot meets a long wet spell. That is why we book maintenance visits before the rain sets in.

Pre-monsoon checklist

  • Clear gutters, valley gutters and downpipes before the first heavy rain
  • Check flashing and ridge capping for gaps the wind can lift
  • Re-seal hairline cracks and tired sealant before water finds them
  • Trim branches that drop leaves onto the roof or scrape the tiles
  • Look at the ceilings indoors for new stains after the first storm

The bi-annual plan puts one visit before each monsoon. For the homeowner’s side of the same checks, see our guide to managing monsoon weather for your roof.

Singapore’s weather year

  • December to early March: Northeast Monsoon, long spells of heavy rain
  • April to May: inter-monsoon, afternoon thunderstorms
  • June to September: Southwest Monsoon, early-morning squalls
  • October to November: inter-monsoon, afternoon thunderstorms

Best months to book a check: November and May

Roof types

Maintenance for each roof type

Each roof fails in its own way, and the checklist changes with the roof.

Ageing roof tiles with stains and moss growth

Tiled roofs

Clay and concrete tiles crack, slip and lose their ridge mortar with age. We replace broken tiles and re-point ridges on the visit. Larger jobs go to our roof tile repair team.

RC roof gutter before waterproofing treatment

RC flat roofs

Flat concrete roofs and gutter slabs hold water where the falls are poor. We check for ponding and membrane wear, and recommend RC roof waterproofing once the membrane has worn out.

RC roof waterproofing ›

Metal roof with rust before waterproofing treatment

Metal roofs

Metal sheets rust at the laps and fixings, and screws work loose as the sheets expand in the sun. We treat early rust and swap failed fixings before they leak.

Pitched roof after waterproofing treatment and coating

Coated roofs

A coated roof needs a wash and small touch-ups between recoats. We look for chalking, peeling and algae, and tell you when a fresh roof tile coating is due.

Reporting

A photo report after every visit

After each visit we send you a photo report of what our crew checked and fixed on the day. Anything bigger gets its own photos and a quote, and you decide what to do and when. Condo MCSTs and managing agents also get a dated maintenance record for the building’s files.

What the report includes

  • Before and after photos of each defect
  • Findings ranked by urgency
  • Minor fixes done on the day
  • A no-obligation quote for larger works

Call us between visits if you notice

  • A new stain or damp patch on a ceiling
  • Water dripping from the eaves where it never dripped before
  • Broken tiles or ridge pieces in the garden or gutter after a storm
  • A musty smell in an upper room after rain

    FAQ

    Frequently asked questions

    Q. How often should I service my roof?

    Most homes do well with a check every six months, timed before each monsoon. Larger, older or commercial roofs usually need quarterly or monthly visits. We suggest a plan after the first inspection, based on the roof’s age and condition.

    Q. What does a roof maintenance visit include?

    A 20+ point inspection, small preventive jobs such as clearing gutters and re-sealing hairline cracks, and a photo report with our findings.

    Q. Is a maintenance contract better than a one-off inspection?

    A contract costs less per visit and builds a record of your roof over time, which helps us spot changes early. We also do one-off inspections, for example after a storm or before you buy a property.

    Q. How much do roof maintenance services cost?

    The fee depends on the size and type of roof and how often we visit. We quote a fixed fee per visit after the first inspection, which is free.

    Q. Will I get a report?

    Every visit ends with a photo report. It covers what we checked and fixed, and lists anything that needs attention later.

    Q. Do you maintain condo and commercial roofs?

    We do. Our clients include landed homeowners, condo MCSTs and managing agents, and owners of commercial and industrial buildings across Singapore.

    We check the roof and fix the small items on the spot. Then we suggest a maintenance plan that suits it.
