Industrial Roof Surveys
Independent, unbiased industrial roof surveys and inspections, nationwide UK coverage
Independent Roof Surveys
Surveyroof carry out independent industrial roof surveys and inspections for factories, manufacturing plants, warehouses, industrial estates, processing facilities and logistics operators across the UK.
Every survey is independent. We don’t carry out roof repairs and we don’t sell roofing materials. That means every report we produce is unbiased. We tell you exactly what we find, with no commercial interest in the works that follow.
What is an Industrial Roof Survey?
An industrial roof survey is a structured, professional assessment of an industrial building’s roof, carried out to identify defects, document the condition of the waterproofing system, and provide the operator or building owner with evidence to plan repairs, maintenance or investment. Industrial roof surveys differ from other commercial surveys in three important ways:
Scale
Industrial roofs are frequently the largest single-span waterproofing systems on any commercial UK building — 5,000 m² to 30,000 m²+, requiring survey methodology built for large-format systematic coverage rather than spot-checking.
Operational continuity
A leak in a factory production hall, a warehouse picking floor, or a manufacturing clean area doesn’t just damage stock — it can halt production, break process control, and cost material money for every hour of downtime.
Environmental complexity
Industrial roofs sit above production environments with distinctive risks: chemical vapours, heat and steam emissions, dust extraction, and in some cases ATEX-classified zones where survey teams need appropriate accreditation.
Our industrial roof surveys are non-destructive. We don’t cut, strip or damage the existing roof. Every finding is documented with photographs, plotted on roof drawings, and reported in a format that supports targeted repair planning.

Site duration depends on roof area and testing scope. Small industrial units (<1,000 m²) typically take one day. Medium industrial buildings (1,000–5,000 m²) take two to three days. Large industrial and distribution buildings (5,000–15,000 m²) take three to five days. Very large distribution facilities (15,000 m²+) can take longer. Reporting adds one to two days off-site. Our ALDI RDC Scotland project, 11,728 m² with combined wet, dry, visual, physical and moisture-mapping methods was completed to full report standard.
Yes we routinely survey live industrial buildings. Our teams work from the roof surface with minimal ground-level impact. Some testing methods (electronic leak detection with water application) may need specific scheduling around operations. We factor operational sensitivity into every mobilisation.

Where a site has ATEX or other classified zones, this needs to be discussed at scoping stage, access and testing methods may need to adapt. Contact us during initial enquiry with site classification details so we can confirm approach.
Yes this is one of the largest areas of our current industrial work. Large industrial roofs are the primary target for commercial rooftop PV in the UK. See our Pre-Installation Solar Roof Survey service for the methodology.
Yes. Multi-site programmes where an industrial operator, property investor or FM company needs consistent independent coverage across multiple industrial buildings are common. We’ll structure the programme, deliver to consistent methodology, and provide portfolio- level summary reporting.
Yes. Our Bolton base supports nationwide coverage. See our Locations page for regional detail.

When You Need an Industrial Roof Survey
Industrial roof surveys are commissioned across the operational lifecycle. The most common reasons UK industrial operators instruct us:
Investigation of active water ingress
Systematic identification of the source of active leaks — particularly important on very large industrial roofs where the point of visible ingress is often distant from the actual breach point.
Pre-solar installation
Confirmation that industrial roof waterproofing can support solar PV before installers commit to the project. Industrial roofs are the dominant target for commercial rooftop PV in the UK — pre-installation surveys are increasingly a standard programme requirement. See our Pre-Installation Solar Survey service and Aldi RDC Scotland case study.
Pre-purchase due diligence
Independent evidence of roof condition before completing a factory or industrial building acquisition, where the roof represents one of the largest single components of physical asset value.
Pre-lease and dilapidations
Baseline condition before an industrial lease begins, or comparative assessment at lease end. Both landlords and tenants benefit from independent evidence to avoid dilapidations disputes on large-format roofs.
Pre-handover certification
Independent third-party verification that a new-build or refurbished industrial roof has been installed to specification. Required by many warranty providers and lenders on large industrial builds.
Warranty periodic inspection
Manufacturer waterproofing warranties on large single-ply industrial systems (Sika, Sarnafil, IKO, Bauder, Renolit and others) frequently require periodic independent inspection to remain valid.
Insurance claims
Independent evidence of storm damage, impact damage or accelerated deterioration to support commercial insurance claims — particularly important where operational disruption is part of the claim.
Planned maintenance baselines
Baseline surveys feeding into ongoing preventative maintenance programmes.
Compliance and reporting
BREEAM, EPC and increasing carbon-reporting requirements are prompting industrial property operators to document roof condition and thermal performance more rigorously.
Portfolio-wide industrial estate surveys
For property investors and industrial estate operators, portfolio-wide independent survey coverage supports both capex planning and estate- level condition benchmarking.

Our Industrial Roof Survey Methods
We select the appropriate combination of non-destructive testing methods for each project based on roof type, access, weather and objectives.
Membrane Condition Surveys
Systematic assessment of the waterproofing membrane using electronic leak detection. The core method for identifying breaches in single ply, felt and liquid systems on large-format industrial roofs.
Electronic Leak Detection
Holiday Detector dry testing and Earth Leakage wet testing, used individually or in combination to identify pinholes, punctures and joint failures on conductive substrates. Every one of our survey vehicles carries both testing units.
Thermal Imaging Leak Detection
Infrared imaging to identify saturated insulation and entrapped moisture, particularly valuable on very large industrial roofs where visual inspection alone cannot cover the area systematically.
Moisture Mapping
Non-invasive impedance scanning to systematically assess moisture within the roof build-up. Essential for locating hidden ingress sources before disturbing the roof covering.
Pre Installation Solar Surveys
Visual condition inspection for industrial roofs where full electronic testing isn’t required or appropriate, including metal-clad and pitched-profile industrial systems.
Roof Maintenance Programmes
Planned preventative maintenance programmes for industrial operators looking to extend roof lifespan and reduce unplanned repair costs.
Featured Industrial-Scale Project: ASDA Pilsworth, Bury
9,000 m² of mixed waterproofing across mineral felt, single ply and liquid systems.
The ASDA Superstore in Pilsworth combines characteristics common to industrial-scale commercial buildings: large-format flat roof, multiple waterproofing systems built up over years of extension and plant works, and constant operational activity below the roof.
Over five man-days on site, Surveyroof combined Earth Leakage Leak Detection wet testing, Holiday Detector dry testing, and full visual and physical inspection. Every defect was photographed and plotted on annotated roof drawings, enabling targeted repair planning across all three waterproofing systems.
The methodology, scale and reporting standard on this project translates directly to industrial buildings, factories, warehouses, manufacturing plants and distribution centres.
