I was standing at the end of a driveway in Lake Oswego last November, rain running off the hood of my jacket, looking up at a two-story house hemmed in by four Douglas firs. The owner wanted the roof documented before the moss came back in spring. I had a ladder on the truck, a 12-foot extension pole in the bed, and a Part 107 drone in the back seat, and over the next hour I put all three on the same roof. Each one showed me something the other two could not, and that is the whole reason the truck carries three tools for one job.
What a ladder does that nothing else does
A ladder gets you close, and close is what you need for the roof surface rather than for the shape of the building. Set on firm ground at a stable angle, it lets me frame individual courses of shingles at the eave, photograph a valley where two planes meet, and show granular loss or cracked sealant at a pipe boot in a way no long lens from the lawn will match. Around f/8, ISO 400, and 1/250 s holds the texture without smearing it.
Two cautions come with it. A ladder shows a strip three or four feet wide, so it is easy to mistake a clean eave for a clean roof. And the closer you stand, the flatter the pitch reads in the frame: a slope that is obviously steep to someone standing below can look nearly level in a close photograph. I always shoot one frame with the horizon visible to keep that context honest.
The pole reaches what a ladder cannot
An extension pole with a camera mount gets the middle of a roof that a ladder cannot safely reach and a drone should not hover over. I use it for ridgelines, chimney flashing, and the top of a dormer, working from a small remote screen and shooting tethered where the cable allows. The pole is slow and awkward, and you are composing blind, but it is the quietest tool in the set: it never enters airspace and never tests a neighbor’s patience. On a wet roof day, quiet matters more than speed.
Where needles and moss collect against a cricket or behind a chimney, the pole is also the only way to show the depth of the pile from above rather than the stain it leaves on the wall below. That stain is evidence, but the pile itself is the cause.
What the drone adds, and what it costs
The drone gives you the roof as a single object: all four planes in one frame, the relationship of the roof to the trees, the gutters, and the drainage. For a homeowner trying to understand why one corner keeps leaking, a straight-down view of the whole footprint is often the picture that explains it. Under Part 107 the standard rules apply, including registration, staying clear of controlled airspace unless you hold authorization, and not flying over people who are not part of the operation.
What the drone costs you is resolution at the detail level and any tolerance for the rain that makes a Lake Oswego roof worth photographing in the first place. It also flattens the texture of moss and shingle alike, because the light is coming from above rather than across. I fly when the sky is overcast and the wind is low, and I keep the drone for the plan view and the tree canopy, not for the close work.
Reading the three sets together
The useful habit is to sort the images the way a written report is built. Ladder frames answer what the surface is doing. Pole frames answer what is sitting up there that cannot be seen from below. Drone frames answer where the water is going and what stands above the roof. When the sets disagree, a dark patch on the drone view that turns out to be tree shadow, the close frame wins, because it was taken closest to the thing in question.
I hand those sets over as three folders with the date and the weather in the names, and let the roofing contractor on that job sort scope from there. Dates and weather matter because a roof that photographs dry in July can look alarming after a week of rain in November, and only the metadata keeps those two truths from being confused with each other.
Frequently asked questions
Can I document a roof with a drone alone? For the overall shape and the tree cover, yes, but the drone will not resolve granular loss or a lifted flashing the way a close frame does, so I pair it with at least a few ladder or pole images.
What lens should I use from a ladder? A 24–70 mm covers most eave and valley work; a longer lens is useful from the ground but rarely from a ladder, where the space you can frame is already tight.
Does rain ruin roof photography? No, but it changes what you are showing. Wet shingles read darker and moss reads greener, so I record the weather with each set so the images are never read out of context.
