Clues that help trace a roof leak
Start with the first date the moisture appeared. Note whether it dripped, spread slowly, or left a dry ring. Take a photograph and mark the edge lightly so later change can be seen. If the stain is near a bathroom, chimney, outside wall, or lower roof connection, share that detail when scheduling the inspection.
When attic access is safe and open, darkened sheathing, rusted nail points, damp insulation, or a visible water track may connect the room to a roof area. Old staining can remain after an earlier repair, so dryness and current weather still matter. Rhino does not treat every dark board as proof of an active opening.
Outside, the search includes shingles, fasteners, pipe boots, ridge material, valleys, skylights, chimneys, sidewalls, kick-out flashing, and prior patchwork. The closest roof opening is not always the source. A higher defect may feed water behind several intact courses before it reaches the interior.
Rain pattern
Steady rain, wind-driven rain, and a quick downpour can expose different roof details.
Interior location
Room, wall, ceiling slope, and attic framing help map the visible mark back toward the roof.
Previous work
Old repair invoices and photos show which areas were opened, sealed, or replaced before.
Roof geometry
Upper slopes, valleys, dormers, walls, and penetrations shape the route water can take.
