Questions to Ask a Roofing Company Before You Hire: What Every Melbourne Homeowner Should Know Before Signing

The Essential Questions (and Why Each One Matters)

These questions are organised by category. Each one protects you from a specific risk.

Licensing, Insurance, and Qualifications

These questions establish whether the company is legally and professionally qualified to work on your roof.

“Are you licensed to perform roofing work in Victoria?”

In Victoria, roofing work requires a registered building practitioner (RBP) registration with the Victorian Building Authority (VBA) for work above certain thresholds. Unlicensed operators cannot be held to the same professional standards, and their work may not be covered by statutory warranties. Ask for the registration number and verify it on the VBA website.

“Do you carry public liability insurance and workers compensation?”

Public liability insurance protects you if the roofing work causes damage to your property or a neighbouring property. Workers compensation insurance protects you from liability if a worker is injured on your roof. Ask for certificates of currency (not just confirmation) and check that the policy is current and covers the value of your project.

“How long have you been operating?”

Experience matters in roofing because the variety of roof types, materials, and problems across Melbourne’s housing stock means a company encounters different scenarios every week. A company with years of experience across tile repairs, restorations, valley replacements, repointing, and painting has seen and solved the full range of issues.

“The cheapest quote is almost always from the operator with no insurance, no registration, and no accountability. If they damage your property, you have no recourse. If a worker falls, you may be liable. If the work fails in six months, they are unreachable. Saving $500 on the quote can cost $5,000 in problems. The licensing and insurance questions are not optional.”

Scope of Work

These questions ensure you understand exactly what is included in the quote and what is not.

“Will you inspect the roof before quoting?”

A company that quotes over the phone or from a photo without physically inspecting the roof is guessing. A professional roof inspection before quoting identifies the full scope: the ridge capping condition, tile condition, valley condition, flashing integrity, gutter condition, and any structural concerns. A quote based on a physical inspection is accurate. A quote based on a phone description is an estimate that will change once the work begins.

“What exactly is included in the quote?”

This is the most important scope question. Ask for a written, itemised breakdown. A roof restoration quote, for example, should specify whether it includes cleaning, tile repairs (and how many replacement tiles are included), rebedding and repointing of the full ridge and hip lines, valley replacement, flashing repair, primer, and two coats of roof coating. A vague quote that says “roof restoration” without itemising the components is impossible to compare with another quote and leaves you exposed to “extras” once the work begins. The roof restoration cost Melbourne guide covers every component that should be listed.

“What is NOT included?”

Equally important. Common exclusions that surprise homeowners: replacement tiles beyond a stated number, gutter replacement or repair, fascia and barge board work, scaffolding or elevated work platform hire (sometimes charged separately), and disposal of old materials. If an exclusion is something your roof needs, it needs to be added to the scope or addressed separately.

“Will you provide a written contract?”

A verbal agreement is unenforceable. A written contract should detail the scope of work, materials to be used, the timeline, the total price, the payment schedule (never pay 100% upfront), warranty terms, and what happens if additional work is discovered during the project (how variations are handled and approved).

Materials and Methods

These questions ensure the quality of what goes onto your roof matches the quality of the workmanship.

“What roof coating product will you use?”

Not all roof coatings are equal. Ask for the specific product name and manufacturer. Premium products (Dulux AcraTex, Shieldcoat, Nutech) cost more per litre but last significantly longer and perform better in Melbourne’s climate than generic or unbranded products. A quote that says “roof paint” without specifying the product is a concern. The best roof paint Australia guide covers the products that perform best.

“Are you using flexible pointing or cement for the repointing?”

Modern repointing uses flexible pointing compound that moves with the roof’s thermal expansion and contraction. Rigid cement cracks within years because it cannot accommodate the movement. Some operators still use cement because it is cheaper. Flexible pointing costs marginally more in materials but lasts significantly longer. The roof repointing cost guide covers this distinction in detail.

“What material will you use for valley replacement?”

Valleys should be replaced with Colorbond steel or zincalume. Galvanised steel valleys corrode faster and have a shorter lifespan. Ask which material is specified in the quote.

“How many coats of coating will be applied?”

The industry standard for roof coating is one coat of primer plus two coats of topcoat. Some operators cut to one coat of topcoat to reduce material and labour cost. This produces a thinner film that fades and fails faster. Confirm that the quote specifies primer plus two topcoats.

Warranty and Accountability

These questions protect you after the work is completed.

“What warranty do you provide on the workmanship?”

A reputable roofing company warrants their workmanship for a stated period (typically 10 to 15 years for a full restoration). This covers issues arising from how the work was done: a tile that was not bedded correctly, pointing that was not applied properly, a valley that was not fitted correctly. Ask for the warranty in writing as part of the contract.

“What warranty does the coating product carry?”

Premium roof coatings carry manufacturer warranties (typically 10 to 15 years depending on the product) that cover the product’s performance: colour retention, adhesion, and weathering. This is separate from the workmanship warranty. The product warranty may be voided if the product is not applied according to the manufacturer’s specifications, which is another reason to use a professional applicator.

“Will you provide a completion certificate and before/after photos?”

Documentation of the completed work protects you for warranty claims, insurance purposes, and future property sales. Before and after photographs, a completion certificate, and copies of the product warranties should be provided at the end of every project.

“What happens if I find a problem after the job is finished?”

A reputable company has a clear process for warranty claims: contact them, they inspect, and they rectify any defect covered by the warranty at no additional cost. Ask what this process looks like and what the typical response time is.

Pricing and Payment

These questions protect your budget and prevent common payment traps.

“Is this a fixed-price quote or an estimate?”

A fixed-price quote means the total price does not change unless you approve a variation in writing. An estimate means the final cost may differ (sometimes significantly) from the quoted figure. Always request a fixed-price quote based on a physical roof inspection.

“What is the payment schedule?”

Industry standard is a deposit (typically 10 to 20 percent) before work begins, with the balance due on completion. Never pay 100 percent upfront. Never pay the full balance before the work is finished and you have inspected the result. Progress payments on larger projects (e.g., 30 percent at commencement, 30 percent at mid-point, 40 percent on completion) are reasonable.

“Are there any additional costs that could arise?”

Ask specifically about: additional tile replacements beyond what is quoted, scaffolding or access equipment if not included, disposal fees, and what happens if hidden damage (decayed battens, rotted timbers) is found once tiles are removed. A transparent company explains these potential variations upfront and requires your written approval before proceeding with any additional work.

Timeline and Process

“When can you start and how long will it take?”

A professional company provides a clear start date and an estimated completion timeline. A standard roof restoration on a single-storey home typically takes 3 to 5 working days depending on the roof size and scope. Delays from weather are normal and expected in Melbourne; ask how weather delays are managed.

“Will your team be on my roof the entire time, or will they split between multiple jobs?”

Some operators start a job, move to another job for a few days, and return later. This extends the timeline and leaves your roof partially completed (and potentially exposed to weather) between visits. A professional company completes your roof before moving to the next job.

“How will you protect my property during the work?”

Roof work generates debris: tile fragments, mortar dust, old valley iron, paint overspray. Ask how the company protects your driveway, vehicles, gardens, and outdoor furniture during the work and how the site is left at the end of each day.
