Can drones inspect internal valley gutters and roof drainage?

Yes. Multi-angle drone cameras fly directly alongside internal valley gutters, parapet troughs, and rainwater sumps to inspect for silt accumulation, standing water ponding, corrosion, and blockages without requiring dangerous roof edge access.

Can roof defects be identified without erecting scaffolding?

Yes. High-resolution optical sensors and calibrated digital zoom capture fine lap-seam tears, punctured membranes, and cracked lead dressings from a safe flight envelope, eliminating the disruption and expense of perimeter scaffolding.

Can the survey identify active waterproofing breaches?

Visual surveys identify physical breaches, split seams, and degraded flashings. When combined with radiometric thermal imaging, we can also map sub-membrane moisture saturation where water has seeped into insulation cores beneath the surface.

What survey outputs are provided?

Deliverables include a high-resolution 2D orthomosaic map of the entire roof deck, categorised photo defect schedules, and a prioritised remedial schedule with fixed pricing for EntireFM in-house roofing repairs.

Can EntireFM complete the identified roof repairs?

Yes. EntireFM operates dedicated commercial roofing divisions. Our qualified roofers execute single-ply heat-welding, liquid coating patch repairs, gutter vacuum clearance, and lead replacement, with all work certified in EntireCAFM.
