Start by noting where and when the water appeared. A stain can be downhill from the roof opening, so share the location and any safe photos with the roofer.
When you call, say whether water is entering now or you are looking at an old stain. Note the nearest exterior wall and whether the issue started after wind or steady rain. That gives the office enough context to plan the first visit.
If you need help finding the source of a leak or deciding what work to request, ask Dekoven Roofing for a roof assessment.
Keep people and pets away from sagging ceilings or areas where water is dripping. Move furniture and electronics out of the way, and put a bucket under active drips. Do not climb on a wet or snowy roof to look for the source.
Take photos of interior staining and of the roof from the ground. Date-stamped pictures help the roofer and may help with an insurance claim.
Ask what the assessment looks at, whether temporary protection is possible and how you will receive findings. Knowing this up front avoids confusion later.
Not always. Water can run along decking or rafters before it shows up, so the roof opening may be a distance away from the stain.
