How to Choose a Roofing Contractor in Malaysia: CIDB Check, Warranty and Red Flags

Choose a roofing contractor in Malaysia who is CIDB-registered, explains the cause of the problem before quoting, gives an itemised written quotation and a written workmanship warranty, and does not demand full payment upfront. Avoid door-to-door offers, vague lump-sum prices and anyone who pressures you to decide on the spot.

Why the choice matters

Roof work is hard for homeowners to check. You rarely see what happens on the roof, and a poor repair may only show itself in the next big storm. A good contractor finds the real cause, fixes it properly and stands behind the work. A poor one patches the stain, gets paid and becomes hard to reach. A few simple checks before you sign make a big difference.

Check CIDB registration

The Construction Industry Development Board (CIDB) registers construction contractors in Malaysia and assigns grades according to the size of work they are allowed to tender for. Registration does not guarantee quality, but it shows the company exists as a registered contractor with accountability.

Ask for the company's full registered name and CIDB registration number.
Check it yourself on CIDB's official online contractor search rather than relying on a photo of a certificate.
Make sure the name on the quotation and invoice matches the registered company.
For larger jobs, check the registration grade and category are appropriate for the work.

What a proper quotation should include

Item	What good looks like	Red flag
Cause of the problem	Explained clearly, with photos from the inspection	"Whole roof is bad" with no evidence
Scope of work	Itemised: area, method, materials	One lump sum with no detail
Measurements	Area in sq ft or length in ft stated	No measurements
Materials	Product type and system named	"Best quality" with no specifics
Warranty	Written, with duration and what it covers	Verbal promise only
Payment terms	Deposit, balance on completion	Full payment before work starts
Timeline	Estimated start and duration	"Can start now, today only price"

Insist on a written warranty

A warranty is only useful if it is written down, names the company, describes the work and states how long it lasts. Ask what is covered (workmanship, materials, or both), what voids it (for example, someone else walking on the roof or installing an aircond bracket later), and how to make a claim. Warranty length should match the type of work.

Type of work	Typical warranty we issue
Minor roof leak repair	Up to 1 year workmanship
Ceramic or heat-reflective roof coating	5 years
Liquid or torch-on membrane waterproofing	10 years
PU-foam insulated metal deck roof	10 years
Stone-coated interlocking roof tiles, full re-roof	20 years
Bathroom waterproofing re-do	5 years

Red flags to watch for

Door-to-door visits claiming they "noticed a problem" on your roof while passing by.
Pressure to decide on the spot, or a "today only" discount.
Refusal to show photos of what they found on the roof.
Demand for full payment before any work starts.
No company name, no registered address, only a mobile number.
Quote far below others with no explanation of what is left out.
Recommending a full re-roof without explaining why repair will not work.
Using only sealant on joints that need flashing or proper waterproofing.

Questions to ask before you sign

What exactly is causing the leak, and can you show me?
Is a repair enough, or is replacement needed? Why?
What materials and method will you use?
How long will the work take, and what happens if it rains?
Who will be on site, and who supervises?
What does the warranty cover, and how do I claim?
What are the payment stages?

How our process works

Our inspections and works are carried out by our CIDB-registered installation partner, with site teams across our coverage areas. The process is straightforward: you send your address, the problem and photos; we confirm a free inspection slot, usually within one to three working days; the technician inspects, explains the cause and gives a quotation on the spot; you confirm, pay a deposit with the balance on completion; and a written workmanship warranty is issued. Prices are indicative until the inspection, for example minor leak repair at RM350 to RM1,800, with the exact price confirmed after the free inspection based on roof design, pitch, access and damage.

Frequently asked questions

How do I check if a roofing contractor is CIDB-registered?

Ask for the company's registered name and CIDB registration number, then check it yourself using CIDB's official online contractor search. Make sure the name on the quotation and invoice matches the registered company. Registration shows accountability, though you should still check the quotation, warranty and payment terms.

How many quotations should I get for roof repair?

Two or three is usually enough for a meaningful comparison. Compare the diagnosis, scope, materials, measurements and warranty, not only the total price. A much cheaper quote often leaves out items or uses a shorter-lived method. Ask each contractor to explain the cause with photos.

Should I pay a deposit for roof works?

A deposit before works start is normal, with the balance paid on completion once you are satisfied. Be cautious of anyone asking for full payment upfront, especially for small jobs. Make sure the deposit amount and payment stages are written in the quotation.

What warranty should a roof repair come with?

It depends on the work. Minor leak repairs usually carry a shorter workmanship warranty, such as up to one year, while membrane waterproofing or a full re-roof carries much longer warranties. Whatever the length, it should be written, name the company and describe what is covered.

Is the cheapest roof quote a bad idea?

Not always, but check what is included. Low quotes sometimes skip flashing, use sealant instead of proper waterproofing, or leave out debris removal and safety. Compare item by item. The best value is the quote that fixes the real cause with a clear written warranty.
