Roof survey — no obligation, ever
Honest assessments, not sales pitches
A roof survey should tell you the truth, not a quote.
We started as masons, and the mason’s standard still holds: inspect properly, photograph everything, diagnose the real cause, and write it down plainly. Our roof surveys exist to give you the facts — whether you’re buying a home, chasing a leak, dealing with an insurer, or simply planning ahead. If your roof is sound, we tell you so. If a repair will do, we never push a replacement. The survey is yours; the decision is always yours.
- Thorough roof survey with honest advice — no obligation to commission any work
- Full colour photographs of every defect and every sound area
- Clear written report in plain English, with urgency and budget guidance
- Independent pre-purchase and insurance surveys accepted by insurers

Three ways to inspect your roof.

Drone Roof Inspection
A safe, detailed view of hard-to-reach roof areas using drone imagery, helping us examine ridges, valleys, flashings and coverings without unnecessary access equipment.

Enquire for pricingWhat we survey
Every kind of roof survey, one honest crew.
From a routine condition check to a formal pre-purchase or insurance survey, one team inspects, photographs and reports — so no detail falls between trades.
01
Roof Condition Assessments
A full top-to-bottom inspection of your roof — slates, tiles, ridge, hips, valleys, flashing, gutters and chimney — graded by condition and remaining life. We tell you plainly what is sound, what is ageing, and what will need attention and when, so you can plan rather than react.
02
Defect Identification
Damp on a ceiling, a stain on a chimney breast, a drip that only shows in certain winds. We trace the symptom back to its true source — failed flashing, a cracked tile, a blocked valley — and document the defect in photographs before any work is quoted, so you know exactly what is wrong and why.
03
Storm & Leak Investigations
After high winds, heavy rain or a sudden leak, we inspect the roof safely, photograph the damage, and identify what was caused by the storm and what was pre-existing. A clear, dated findings report you can hand straight to your insurer, with no guesswork and no exaggeration.
04
Pre-Purchase Roof Surveys
Buying a home? Before you commit, we survey the roof independently and report on its true condition, remaining lifespan and any near-term repair costs — the detail a standard mortgage valuation skips. A few hundred pounds of survey can save you thousands in unexpected re-roofing bills.
05
Maintenance Planning
For landlords, managing agents and owners of larger properties, we build a scheduled maintenance plan based on a full survey — what to inspect, when, and what to budget for over the next five to ten years. Small, timely interventions that prevent the big, costly failures.
06
Written Findings & Photographs
Every survey ends with a clear written report — defects listed by location and severity, full colour photographs, honest recommendations, and an indication of urgency and budget. No jargon, no pressure to commission work, just the facts you need to decide.
When to book a survey
Six signs it’s time to have the roof looked at.
- Damp patches, brown staining or mould on ceilings or chimney breasts inside
- Slipped, cracked or missing tiles or slates visible from the ground
- A leak that appears only in certain winds or during heavy, driving rain
- You are buying a property and want an independent view of the roof’s true condition
- Mortar, slate or debris collecting in the gutters or on the ground below
- Your roof is over 20 years old and has never had a professional inspection
Storm damage — photographed and reported
A dated report your insurer will accept
How we survey
Every stage, documented properly.
From safe access to the written report, one crew owns the whole survey — so no defect is guessed at and no finding is left undocumented.
01
Safe Access & Inspection
We set safe access — roof ladder, scaffold or cherry picker as the job demands — and inspect every part of the roof, inside the loft and out, in line with working-at-height best practice. No survey is rushed, and no area is guessed at from the ground.
02
Photograph Everything
Every ridge, valley, flashing, abutment, chimney and gutter run is photographed in close detail. You see exactly what we see — the defects, the sound areas, and the early warning signs — so the report is evidence, not opinion.
03
Diagnose the Cause
We trace each defect back to its true cause — failed lead, a cracked tile, condensation, a blocked valley, movement in the stack — so the recommendation fixes the problem at its source, not just the symptom showing inside.
04
Written Findings Report
You receive a clear written report: each defect by location and severity, full colour photographs, and an honest assessment of remaining roof life. Plain English, no jargon, and no inflated scare stories to push work you don’t need.
05
Recommendations & Budget
For every defect we set out the options — repair now, monitor, or plan for later — with an indication of urgency and a budget cost. You stay in control of what is done, when, and by whom. No obligation to commission any work from us.
06
Follow-up & Handover
We talk you through the report in plain language, answer every question, and leave you with a document you can keep, share with an insurer, or hand to a buyer’s solicitor. The survey is yours — we simply provide the expertise.
Why our surveys differ
Six things every roof survey gets.
A survey is only worth what it tells you. We inspect thoroughly, photograph everything, diagnose the true cause, and write it down — with no pressure to buy work you don’t need.

What we inspect
The layers a proper survey covers.
A roof is a system of layers and joints. We inspect all of them — the covering, the rainwater details and the abutments — so nothing is missed.
Ridge, Hips & Tiles
Every ridge, hip, tile and slate inspected for movement, cracking and spalling — the covering that takes the full force of British weather, graded by condition and remaining life.
Valleys, Gutters & Eaves
Valley gutters, eaves and rainwater runs checked for blockages, sagging and standing water — the details that move rain safely away, and the most common hidden cause of interior leaks.
Flashing & Abutments
Lead flashing, soakers and chimney abutments inspected for lifting, cracking and failed mortar — the joints where the roof meets walls and stacks, and where most leaks actually start.

Word of mouth
Neighbours talk. Written reports prove it.
“We were about to exchange on a 1930s semi when Corner Stone surveyed the roof. They found failed flashing and a cracked valley that the valuation missed — we renegotiated £4,000 off the price. The survey paid for itself ten times over.”
“A damp patch that three roofers couldn’t explain. Corner Stone surveyed it properly, photographed the failed lead under the chimney, and diagnosed the cause in one visit. Honest, thorough, and no pressure to book work we didn’t need.”
“After the January storms they inspected our roof, photographed every displaced slate, and wrote a report our insurer accepted without question. Calm, professional, and the paperwork was spotless. Exactly what you want after a bad night.”
