Roof Inspection: What It Includes, Cost and When You Need One

Most roofs go years without anyone looking at them properly. Slipped tiles, cracked ridge mortar, failing flashing and blocked gutters usually start small and quiet, and the first sign many owners get is a stain on the ceiling. A roof inspection finds these faults early, when they are cheap to fix. This guide explains what a roof inspection includes, the different types of survey, what each one typically costs in the UK, when you should book one and how to do a safe ground-level check yourself.

What Is a Roof Inspection?

A roof inspection is a structured check of the roof covering, the roof structure and the parts that keep water out, including gutters, flashings, chimneys and the roofline. It can be done from the ground, from a ladder or scaffold, from above with a drone or from inside the loft, and the best ones combine at least two of those views. The result is usually a condition report that lists any defects, how urgent they are and what repairs are needed. It is different from a roof repair quote, because an independent inspection is not trying to sell you a job.

What Does a Roof Inspection Cover?

Outside the Roof

• Roof covering: slipped, cracked, missing or worn tiles and slates, and moss or lichen build-up.
• Ridge and hips: loose or cracked mortar and bedding.
• Valleys and flashings: lead, zinc or sealant failing where the roof meets walls, chimneys and other roofs. See our roof flashing guide.
• Chimney stacks: pointing, flaunching, pots and lean.
• Gutters and downpipes: blockages, leaks, sagging and loose brackets.
• Roofline: fascia, soffit and bargeboards for rot, gaps and damp.
• Flat roofs: ponding, blisters, splits, open seams, outlets and upstands.

Inside the Loft

• Roof timbers: rafters, purlins, joists and battens for rot, woodworm or movement. Our guide to roof timbers explains what to look for.
• Underlay: tears, sagging or water staining.
• Daylight: chinks of light showing through the roof covering.
• Insulation: depth, gaps and wet or compressed patches.
• Ventilation: blocked eaves, condensation and mould. See our roof ventilation guide.
• Water tanks, pipes and flues: leaks and damage near the roof structure.

Types of Roof Inspection

Roof Inspection Cost in the UK

Prices vary with roof size, access, region and how detailed the report is, and sources differ, so treat these as general guides based on 2026 UK price guides. Many roofers will inspect for free or at low cost as part of a repair quote, but that is not the same as an independent survey.

Scaffolding, if needed for close access, is usually extra. A full building survey for a house purchase, such as a RICS Level 2 survey, often costs several hundred pounds and covers the roof as one part of the property.

When Should You Have a Roof Inspected?

• Before buying a house, especially an older one or one with a visible problem.
• After storms, hail or heavy snow.
• When you see warning signs, such as damp patches, daylight in the loft, slipped tiles or sagging.
• Before a major repair, loft conversion, solar panel installation or re-roof.
• For insurance or a dispute, where independent evidence is useful.
• Routinely, every few years for most roofs, and more often on older or flat roofs. Our roof repair guide explains common faults and when to act.
• For landlords, as part of a regular property maintenance plan.

What Should the Report Include?

• Photographs of each defect, with their location marked.
• A description of the covering, structure and any previous repairs.
• A priority rating for each issue, such as urgent, soon or monitor.
• Recommended repairs and, ideally, a rough cost range.
• An estimate of the remaining life of the covering.
• Notes on ventilation, insulation and any moisture concerns.

If the report suggests major work, our guides to roof leak repair cost and new roof cost can help you judge whether the figures are realistic.

Who Should Carry Out the Inspection?

• A roofer: best at spotting repairs and pricing them, but they may be paid by the repair work that follows.
• A chartered building surveyor: independent, with formal training and a written report. The Royal Institution of Chartered Surveyors can help you find one.
• A drone operator: cost-effective for access and photos, but not a substitute for a loft check.

Check insurance, qualifications and examples of reports before you book, and be cautious of anyone who knocks on your door claiming to have spotted a problem from the road.

A Safe Ground-Level Roof Check

Working at height is dangerous. Never climb onto the roof to inspect it yourself, and avoid leaning ladders against gutters. You can learn a lot from the ground and the loft.

1. Look from the ground with binoculars. Check the tiles, ridge, hips and chimney for gaps, tilts or missing pieces.
2. Check the roofline. Look for peeling paint, stains and gaps at fascias, soffits and bargeboards.
3. Inspect the gutters. Look for overflow stains, plants growing and sagging. See our gutter cleaning guide for safe clearing.
4. Look for debris. Fallen tiles, mortar pieces or moss in the garden are warning signs.
5. Check the ceilings. Brown stains, bubbled paint or musty smells point to a leak.
6. Check the loft. With a torch, look for daylight, damp patches, stained timbers and wet insulation, staying on the joists or boards.

Red Flags to Avoid

• Door-to-door callers offering a free inspection and then showing photos from your roof.
• Pressure to sign immediately or pay a large deposit.
• A report with no photos, no location details or no priorities.
• Claims that the whole roof must be replaced without evidence.
• No insurance or no address.

Safety and Asbestos

Working at height is dangerous. Roofs can be slippery, fragile or steep. Use professionals with access equipment or drones, and never step on rooflights or cement sheets.

Asbestos warning. Older roofs, soffits and outbuildings may contain asbestos cement. Do not drill, scrape or disturb suspect materials. A competent surveyor can identify them, and the HSE asbestos guidance explains the rules.

Frequently Asked Questions

How much does a roof inspection cost?

As a general guide, from free to around £250 for a roofer’s visual check, £150 to £500 for a drone inspection and £500 to £1,000 or more for a chartered surveyor’s structural report.

How often should a roof be inspected?

Every few years for most roofs, and after any storm or when you notice signs of trouble. Older roofs and flat roofs benefit from yearly checks.

Is a drone roof inspection as good as a visual one?

Drones are good for access and photographs, but they cannot inspect the loft or test the materials by touch. The best inspections combine methods.

Do I need a roof survey when buying a house?

If the roof looks old, worn or hard to see, a specific roof inspection is worthwhile alongside the general survey, because repairs can be costly.

Can I inspect my own roof?

You can check from the ground and in the loft, but do not climb onto the roof. Use binoculars and a torch, and call a professional for anything you cannot judge.

Will a roof inspection find a leak?

Often, but not always. Leaks can be intermittent, so a good inspector checks the loft and may use a hose test or thermal imaging.

Final Thoughts

A roof inspection is one of the cheapest ways to protect a home. Choose a method that suits the roof, make sure the report is independent and detailed, and use it to plan repairs in order of priority. Keep your own ground-level and loft checks going between inspections, and treat any suspect old materials as asbestos until proven otherwise.
