If your buildings insurer has asked for a flat roof inspection report before they will offer or renew your policy, this is increasingly common — and straightforward to resolve. Insurers treat flat roofs as higher-risk than pitched roofs, and many now require independent evidence of the roof’s condition before providing cover.

This guide explains what insurers are looking for, what a flat roof inspection involves, and how North West Roof Surveys can provide the report you need.

Why Do Insurers Ask for a Flat Roof Inspection?

Flat roofs have a shorter typical lifespan than pitched roofs and are more susceptible to water ingress, pooling, and membrane deterioration. Insurers are therefore more cautious about properties with flat roofs — particularly older flat roofs or those that have not been inspected recently.

Common reasons an insurer may require a flat roof survey for insurance include:

The flat roof is over a certain age (often 10–15 years) and has not been recently replaced
A previous claim has been made for water ingress or storm damage
The policy is being renewed and the insurer wants to confirm the roof is maintained
You are taking out new buildings insurance and the property has a flat roof section
The insurer’s underwriters require condition evidence before agreeing terms

In most cases, providing a professional inspection report resolves the insurer’s concern and allows the policy to proceed. In some cases it may result in conditions being attached to the policy — for example, requiring certain remedial work to be carried out within a specified period.

What Does a Flat Roof Inspection for Insurance Cover?

Our flat roof inspection reports assess the full condition of the flat roof covering and associated elements, including:

Roof membrane condition — felt, EPDM, GRP fibreglass, or asphalt, depending on roof type
Surface drainage — outlets, falls, and evidence of pooling water
Upstands and abutments — where the flat roof meets walls or parapet walls
Flashings — lead or aluminium flashings at junctions and penetrations
Parapet walls and copings — condition of mortar and pointing
Skylights and roof lights — seals, frames, and glazing condition
Evidence of previous repairs — patch repairs, lap joints, or temporary fixes
Signs of water ingress — staining, blistering, or deterioration of the membrane

We use high-resolution photography throughout the inspection and, where appropriate, drone technology to access flat roofs that cannot be inspected safely from ground level or via ladder. Every defect or area of concern is documented with photographic evidence in the written report.

What Format Is the Report In?

Our flat roof insurance reports are written in plain English, structured clearly, and delivered as a PDF by email — typically within 24 hours of invoice payment. The report covers the condition of each element inspected, notes any defects, and includes recommendations for remedial work where required.

If your insurer has sent you a specific requirements document or a pro-forma report template they would like completed, send it to us before the inspection and we will ensure the report meets their requirements. We deal with a wide range of insurers and loss adjusters and can advise if something is outside what we can provide.

Storm Damage Reports for Insurance Claims

If your flat roof has been damaged by a storm and you are making an insurance claim, we can also provide a storm damage roof report. These reports document the damage, distinguish storm damage from pre-existing wear, and provide the evidence your insurer or loss adjuster needs to assess the claim.

See our insurance roof reports page for more information on storm damage and claims-related surveys.

Why Use an Independent Surveyor for Your Flat Roof Inspection?

North West Roof Surveys is fully independent. We carry out inspections and produce reports only — we do not carry out flat roof repairs or replacement work, and we have no commercial relationship with any roofing contractor.

This matters for insurance purposes because an independent report carries more weight than a report produced by a contractor who also stands to benefit from the remedial work they recommend. Insurers and loss adjusters are experienced in identifying reports that may be influenced by commercial interest — an independent report removes any doubt.

We also hold professional indemnity insurance voluntarily. Most independent roof surveyors are not required to carry PI cover and many choose not to. Our PI insurance means there is a formal means of redress if an error in our report causes financial loss. Find out more about our PI cover.

How Much Does a Flat Roof Inspection for Insurance Cost?

Prices start from £350 for a standard residential flat roof inspection. The final cost depends on the size and complexity of the roof, the location of the property within our coverage area, and whether drone technology is required for access. We provide clear, upfront pricing — no hidden charges.

How Quickly Can You Carry Out the Inspection?

We can usually book flat roof inspections within a few days of enquiry. If your insurer has set a deadline for the report, let us know and we will prioritise accordingly. We respond to all enquiries within one working hour.
