Roof inspection cost, and what a roofer checks

Published 12 October 2026 · Updated 13 October 2026

What a roof inspection costs in Sydney

Some roofers look at a roof before quoting a repair without charging separately for it, so ask. A written report is different: it takes time on the roof and at the desk, and the price depends on what it’s for. These are the published prices we found, each with its publisher:

Published roof inspection and report prices

Two Sydney roofing businesses’ undated pages, checked 12 October 2026; neither says whether GST is included. The first four are “from” prices, and the publisher says “Pricing depends on the property, access, inspection purpose, thermal imaging and level of written documentation required.” The last is a Sydney contractor based in Ermington, which says its report covers the “accessible roof covering, flashings, drainage and other areas”.

Before booking, ask whether the fee is credited against any repair, whether the report includes photos, and how long it takes to arrive.

Which kind of inspection you need

A maintenance check

A look over the roof and gutters with a short written summary. Good every few years, or before the storm season, on an older tile roof.

Buying a house

A pre-purchase building inspection looks at the whole house, and the roof is one part of it. If the roof is old, steep, fibro or hard to see, a roofer’s report goes further on that one item, and can include a repair quote you can take into the negotiation.

An insurance or storm report

Records the damage and the roofer’s view of the likely cause, with photos. If you’re claiming, see does home insurance cover a leaking roof or storm damage? for what the report should cover.

A leak investigation

A targeted search for where water gets in, starting in the roof space. That’s usually part of a roof leak repair rather than a separate report.

What a roofer checks

A Sydney roofer’s inspection page says its inspection covers “all aspects from tiles, and metal surfaces to gutters, downspouts, and flashing”, looking for “cracked or shifting ridge caps, decaying or cracked battens, and issues with valley irons and whirlybirds”. On a Northern Beaches roof, our checklist adds the salt and the trees:

• Tiles: cracked, slipped or crumbling tiles, and lichen holding moisture
• Ridge and hip capping: cracked or missing pointing, loose caps (see roof repointing)
• Metal roofs: rust at screws, laps and cut edges, loose or missing screws, and the grade of steel for the distance from the surf
• Valleys and flashings: rusted valley irons, lifted flashings at walls, chimneys, skylights and vents
• Gutters and downpipes: leaf build-up from gums and angophoras, rust on the underside, box gutters and their overflows
• The roof space: water stains on timbers, daylight, damp or missing sarking, and condensation under metal
• Fibro: whether the roof or eaves may contain asbestos, so nobody pressure cleans or walks on them

BlueScope’s maintenance bulletin (TB-4) asks for steel in unwashed areas, such as gutter undersides and fascia, to be washed “three monthly in locations such as coastal areas where marine salt spray is prevalent”, and an inspection is a good time to see whether that has been happening.

How often to have a roof inspected

Monier’s FAQ recommends having the roof checked “Every five to seven years” by an expert tradesperson, and says “The number one maintenance issue is cleaning the gutters, downpipes and valleys of your roof.” A Western Sydney roofing contractor’s cost guide recommends more often, every 12 to 18 months; that’s a roofer’s view rather than a manufacturer’s.

Our advice for the Beaches: have it looked at after any storm that brings down branches or lifts tiles in your street, before you buy, before you paint or restore, and whenever you see a ceiling stain, mortar in the gutters or rust streaks on a metal roof.

Checking your own roof safely

You can do a useful first look without climbing anything high. From the ground, use binoculars or a phone camera’s zoom on the ridges, valleys and gutters. From inside, look in the roof space with a torch, stepping only on the joists. We’d rather you stayed off the roof itself: SafeWork NSW treats work with a risk of a fall of more than 2 metres as high-risk construction work, and warns that asbestos roofs “are brittle and you can easily fall through.”
