What flashing protects
Flashing helps direct water away from roof intersections and penetrations. It is used around details such as chimneys, vent pipes and roof-to-wall connections. These areas need attention because the covering meets another surface rather than continuing uninterrupted.
A provider may need to distinguish a flashing defect from damaged nearby roofing or another water entry route. Ask them to explain the relationship between the visible joint, surrounding covering and the indoor symptom.
Describe the location without diagnosing it
Tell the provider whether water appears beside a chimney breast, below a vent, at an exterior wall or somewhere else. If you can see a loose piece of metal from a safe position on the ground, mention it. Avoid moving or lifting the material yourself.
When did it start?
Note the first rain when you noticed it, whether wind seemed relevant and whether nearby work happened before the leak. A short timeline is more useful than an assumption that every joint needs resealing.
What does the proposed work address?
Ask whether the recommendation concerns a vent boot, chimney detail, wall junction or another component. Ask what existing material will be retained, what will be replaced and how adjacent roofing will be handled. A written scope makes these distinctions easier to discuss.
Roofing and other building components can overlap
A chimney concern may involve more than the roof junction. Ask whether the provider's assessment covers only the roofing detail or whether another qualified trade is needed. Fountain RoofLink cannot determine that from a description or promise that every issue will be handled by one provider.

Questions about flashing & roof joints
Is sealant always the answer?
A visible gap does not determine the repair. Ask the provider what has failed and why their proposed approach addresses that component.
Should I call about a leak beside a chimney?
You can describe that symptom and ask about a roofing assessment. The provider should explain whether the concern falls within their scope or needs another trade.
