Roof Inspection Evidence for Property Portfolios

See where remote roof imagery helps, where access or further investigation is still needed, and how to keep a useful record across buildings.

The roof is the costliest blind spot

Flat roofs, membranes, upstands, outlets and drainage drive the unplanned spend on most estates, and they are exactly what nobody can safely or cheaply inspect by hand. So they go unwatched until they leak.

Full roof coverage, no access

A drone captures the entire roof at high resolution, the whole surface rather than the corners someone could safely reach, with no scaffold and no one working at height.

What a roof inspection surfaces

Membrane splits, blistering and lap failures, ponding and drainage problems, failed flashings and upstands, and blocked outlets. With radiometric thermal, it can also flag the signature of trapped moisture for investigation.

From finding to CAPEX

Every finding is graded on one risk scale, located on the roof, and costed into a time-phased plan. Worst risk first, safe deferrals justified, ready for the board.

One roof or a whole estate

Run it across the portfolio on an annual cycle and Ovrsite Enterprise holds the trend, so roof spend is planned against evidence rather than triggered by the next leak.

We will discuss the scope and next step with you.

See it on your estate.

The fastest way to understand what building intelligence does for your portfolio is to see it on one of your own buildings. We can discuss a scoped pilot.
