A property's distance from water can inform product review, but it is not the only exposure consideration. The type of water, environment, and specific warranty terms matter. A map measurement does not independently establish material suitability.
What to do next
Use location information to prepare questions for the manufacturer and contractor. Ask for written clarification where terms are ambiguous. Keep a screening tool's result separate from product approval, warranty eligibility, and the building-specific roof design.
