About the PortalChoose the level of support your roof needs. A core programme, with specialist services and optional add-ons layered on top.
Every programme includes a core set of features, with specialist services for complex roofs or advanced assessments, and optional add-ons to increase coverage and support long-term asset planning. You get a plan matched to the building, without paying for services you do not need.
Core features
Bi-annual roof inspections
Routine spring and autumn visits that assess the full roof area, identify early-stage defects and ready the roof for seasonal weather.
Condition grading
Every roof area is graded from A to D so current condition is clear, change is tracked over time and maintenance can be planned with confidence.
Risk scoring
Each issue is assessed for likelihood and impact, helping facilities teams prioritise urgent items and manage budgets more effectively.
Full photographic reporting
Every visit includes a clear, illustrated report with photographs, marked-up observations and recommended actions for record keeping.
Drainage maintenance
Gutters, hoppers and outlets are cleared of debris to prevent blockages, standing water and winter back-ups that commonly lead to leaks.
Debris and vegetation removal
Leaves, moss and other organic matter are removed from the roof surface to maintain drainage performance and reduce membrane wear.
Flashing, upstand and perimeter checks
Detailed inspection of all edges, terminations and junctions where most leaks begin, ensuring trims, flashings and upstands remain secure.
Penetration and plant inspections
Inspection of rooflights, pipe penetrations, HVAC mounts, PV brackets and other equipment to ensure all seals, fixings and supports are intact.
Basic sealant renewal
Renewal of perished or loose sealant at key points around the roof to prevent water ingress and prolong the life of junctions and detailing.
Minor repairs completed on the visit
Where safe and practical, small issues such as loose fixings, minor splits or unsecured trims are resolved during the inspection to reduce call-outs.
Specialist services
Core sampling
Extraction and analysis of a roof core to confirm build-up, trapped moisture and substrate condition before recoating or renewal.
Moisture mapping
Non-destructive survey across the roof area to locate trapped water and hidden saturation that a visual inspection cannot reveal.
Thermographic survey
Thermal imaging that highlights variations in the build-up, supporting accurate diagnosis of failing insulation and water ingress.
Drone survey
Aerial inspection for large, steep or inaccessible roofs, capturing high-resolution imagery without extensive access equipment.
Structural and falls assessment
Assessment of ponding, poor falls and load-related issues, with recommendations to correct drainage and prolong roof life.
Cut edge corrosion treatment
Targeted treatment of corroding sheet laps and fixings on metal roofs, halting deterioration before it reaches the fixing line.
Optional add-ons
Extended Basecare guarantee
Longer-term cover for materials, workmanship or both, recorded within the Basecare guarantee framework and managed in the Portal.
Priority emergency response
Faster attendance for leaks and storm damage, with local contractors keeping response times short and downtime to a minimum.
Additional inspection visits
Extra visits for roofs with heavy plant, foot traffic or a history of defects, added to the standard bi-annual schedule.
Localised recoating
Application of a liquid-applied system to worn or failing areas, restoring waterproofing and extending the life of the existing roof.
Gutter lining
Seamless lining of failing gutters to stop leaks at the perimeter and protect the structure below without full replacement.
Portfolio condition reporting
Consolidated reporting across multiple sites, giving asset and facilities teams a single view of roof condition and forward spend.
A system to cover every problem. Liquid-applied waterproofing matched to the condition of the roof and the demands of the site.
A full range of liquid-applied systems solves the most common issues found on flat roofs. Whether the problem is leaks, ageing membranes, blistering, cracking, ponding water or failing details, a system can be matched to the roof and the site.
