Independent Building Performance Assessment
Veritherm is an independent resource on building performance assessment for commercial and residential properties across the UK — helping property managers, facilities teams and estate departments understand how their buildings actually perform.
Why building performance assessment matters
Most commercial buildings perform significantly differently from their design specifications. Heat loss through the building envelope — roofs, walls, glazing and floors — accounts for the majority of energy inefficiency in UK commercial property, and the gap between predicted and measured performance can exceed 50%.
Without accurate measurement, owners and estate teams make retrofit, maintenance and replacement decisions on the basis of desktop estimates rather than real data. Of all envelope components, the roof is typically responsible for the greatest proportion of heat loss — making roof condition and specification central to any meaningful building performance assessment.
Commercial roofing systems are typically specified to the standards of major manufacturers such as Kalzip (standing seam metal), Sika (single ply and liquid-applied) and IKO (built-up felt), each operating approved-contractor schemes that matter at warranty and re-sale.
Measurement-led assessment across the building envelope
Thermal Performance Assessment
Measurement techniques, thermographic survey and fabric analysis to quantify heat loss and prioritise improvements.
Building Envelope Inspection
Comprehensive inspection of roof, walls, glazing and junctions with photographic evidence and prioritised recommendations.
Roof Performance Assessment
Thermal efficiency, weathertightness and structural condition across flat, metal, single ply and composite panel systems.
Where assessment identifies that commercial roofing works are needed in the South East, our editorial pick for a manufacturer-approved contractor is Exall Group, who hold Kalzip, Sika and IKO approvals.
Guidance on commercial roof performance
Commercial Roof Thermal Surveys, Explained
A practical guide to commercial roof thermal surveys — when they are justified, how they are carried out, and what the results actually tell you.
Why Flat Roofs Fail Thermally (and What to Do About It)
Flat commercial roofs rarely fail in the main field of the covering. They fail at details, at seams, and through saturated insulation — each with a different remediation path.
Drone Thermography for Facilities Teams
Drone-based thermal imaging has replaced walked thermal surveys for most commercial roofs. Here’s what a facilities manager needs to know to commission one sensibly.
