An interior water mark does not necessarily sit below the source of a leak. Water can travel through the roof assembly before it appears inside. An assessment should consider the surrounding details as well as the visible symptom.
02
Look beyond the damaged area.
A useful recommendation explains whether the surrounding roof is in sound condition and how the repair will connect to it. Flashing, penetrations, edges, and drainage details may all be relevant.
When you first noticed the issue
Whether it appears during particular weather
Previous repairs or recurring symptoms
Any observations made safely from the ground
03
Understand what the repair addresses.
Ask what is included, what remains outside the scope, and whether further investigation is needed. A repair should be considered in the context of the whole roof. Do not climb onto a roof to gather information for this example request.
