Is a drone inspection as good as a roof walk?

Drone inspection is excellent for getting overall photos and spotting big-picture issues (missing shingles, obvious damage, drainage patterns). It’s poor for the details that actually predict roof failure: granule wear, shingle adhesion, flashing condition, and decking soft spots. Trill uses drones on every initial inspection as a screening tool, then walks the roof to verify and find what the drone missed.

A walk-only inspection or a drone-only inspection both miss things a combined inspection catches. The drone-only inspections often get sold as ‘safer’ or ‘cheaper’ but the missed-detail rate is about 25 to 30% versus walk inspections. Trill never charges extra for the combined approach; the drone runs alongside the walk on the same visit. If a contractor refuses to walk your roof, that’s a flag.
