What Happens During a Professional Roof Survey?

Most homeowners only think about their roof when something goes wrong.
A leak appears. Tiles end up in the garden after a storm. Damp starts showing on a ceiling.
A professional roof survey is a detailed inspection carried out to assess the condition of your roof, identify defects, and determine whether repairs are needed.
At Daniel Roofing and Guttering, roof surveys are practical, hands-on inspections - not paperwork exercises. We assess real roofing issues across homes in Accrington, Lancashire and Greater Manchester, then explain clearly what we’ve found.
Quick Answer:
A professional roof survey involves inspecting the external roof covering, flashings, chimney, guttering and (where accessible) the loft space. The roofer identifies damage, underlying causes, and advises whether repair, monitoring or replacement is required. Photographic evidence is usually provided.
Signs You Might Need a Roof Survey
You may benefit from a roof survey if you’ve noticed:
Damp patches on ceilings
Water marks inside the loft
Slipped or missing tiles after strong winds
A sagging or uneven roof line
Persistent moss build-up or overflowing gutters
Small warning signs often point to larger underlying issues.
What Is a Roof Survey?
A roof survey is a detailed inspection of:
Roof tiles or slates
Ridge and hip tiles
Lead flashings
Chimneys
Valleys
Flat roof coverings
Loft space (if accessible)
The aim is to assess the overall condition of the roof, identify any visible defects, and determine whether repairs or further action are required.
It’s commonly booked:
After storm damage
Before buying a property
If damp or leaks appear
Before replacing a roof covering
If a roof is 20+ years old
Step 1: External Roof Inspection
The survey starts with a full visual inspection from ground level and, where safe, from ladder access.
We check for:
Cracked, slipped or missing tiles and slates
Loose ridge tiles
Failing mortar
Damaged or lifted lead flashing
Moss build-up holding moisture
Ponding on flat roofs
Signs of sagging or uneven roof lines
Many properties across Lancashire and Greater Manchester have ageing slate and tiled roofs where ridge lines, chimney flashings and valleys are common weak points.
Guttering is also inspected carefully. Poor fall, open joints, blockages or overflowing gutters often cause internal damp - even when the roof covering itself is sound.
In Lancashire especially, heavy rainfall and freeze-thaw cycles can accelerate small issues into bigger ones. That’s why attention to detail matters.
Step 2: Internal Loft Inspection (If Accessible)
If there’s safe loft access, the inside of the roof is checked as well.
We look for:
Daylight coming through gaps
Water staining on timbers or insulation
Damp patches
Signs of rot or timber decay
Poor ventilation
Condensation build-up
Often, internal signs tell you more than what’s visible outside.
Step 3: Identifying the Root Cause
A professional survey isn’t just about spotting damage - it’s about understanding why it’s happening.
Common underlying causes include:
Age-related wear
Poor previous repairs
Incorrect tile fixing
Blocked or poorly aligned gutters
Failing underlay
Storm displacement
Clear diagnosis avoids unnecessary work. Not every issue means full roof replacement.
What Problems Are Most Commonly Found?
During roof surveys across the region, the most frequent issues include:
Slipped slates on older pitched roofs
Loose ridge tiles
Lead flashing pulling away from chimneys
Moss retention holding moisture
Blocked gutters causing overflow
Minor flat roof splits
Many of these are straightforward repairs if caught early.
How Long Does a Roof Survey Take?
For an average property:
Smaller roofs: 30–60 minutes
Larger or more complex roofs: up to 1–2 hours
After the inspection, findings are explained clearly.
We provide a verbal summary and send photographs via WhatsApp so you can see exactly what’s been identified. If repairs are required, you’ll receive a clear quote outlining the work.
No vague reports. No scare tactics.
What Happens If Problems Are Found?
If minor issues are discovered, you’ll be advised on:
What needs repairing
What can wait
What should be monitored
If larger issues are present, options will be explained honestly - whether that’s targeted repair work or, in some cases, replacement.
The goal is clarity. Not pressure.
Roof Survey vs Building Survey – What’s the Difference?
A building survey (often carried out by a chartered surveyor) assesses the entire property structure.
A roof survey carried out by a professional roofing contractor focuses specifically on the roof’s condition and practical repair needs.
If you’re buying a property, a building survey may flag concerns. A dedicated roofing survey then provides a clearer, practical assessment of what’s actually required.
Do You Need a Roof Survey for Insurance?
Sometimes insurers request evidence of damage before approving claims.
A documented inspection with photographic evidence can support this process. However, insurers will not usually cover issues caused by long-term neglect.
Regular maintenance reduces the risk of claim disputes.
When Should You Book a Roof Survey?
You should consider booking one if:
You’ve noticed leaks or damp
Your roof is ageing
You’ve experienced storm damage
You’re buying or selling a property
You’re planning solar panel installation
You want peace of mind
Catching small issues early is always cheaper than dealing with major internal damage later.
FAQs
Before we wrap up, here are a few common questions homeowners ask about roof surveys.
How much does a roof survey cost in the UK?
The cost of a roof survey depends on the size, height and complexity of the property. A straightforward inspection is typically less expensive than a full building survey, as it focuses purely on the roof. The best way to determine cost is to arrange an initial discussion so the roof can be assessed properly.
How long does a roof survey take?
Most roof surveys take between 30 minutes and two hours, depending on property size and access. Larger or more complex roofs may take longer.
What are red flags during a roof survey?
Common warning signs include sagging roof lines, multiple slipped tiles, deteriorating flashing, wet or decaying timbers in the loft, and signs of long-term water ingress.
Can I inspect my own roof?
You can carry out basic visual checks from ground level, but climbing onto a roof without proper training and equipment can be dangerous. A professional inspection ensures safety and a more accurate assessment.
Do I need a roof survey before buying a house?
If a building survey highlights potential roof concerns, a dedicated roof survey provides a clearer, practical assessment of the roof’s condition and any likely repair requirements.
