Why do I check roofs on condos and why do I carry a video pole cam.
A real camera rather than a tablet helps as well since these shots were taken 8:00 at night.
Roof had no access at 3 stories up.
See if you can figure out what I just saw while working a report just now.
These are crop shots off a HD video with gamma correction so it looks like daylight.
first and third you can clearly see the staining, second I would wonder about back up under shingles as well. Photo of floor platform it is clear header is painted and caulked so cracking is not from expansion. it can only be moisture from above disclouring mortar, Good catch.
