Changing a shingle roof to tile is an assembly conversion, not a simple exchange of visible materials. The existing structure, deck, roof edges and transitions must be evaluated for the selected tile system. A tile-only price does not describe the full scope of that decision.
Establish structural suitability first
Tile products and assemblies vary, so assumptions based on the word lightweight or on a neighboring house are not enough. Ask who will determine whether the existing structure is suitable and what documentation is required for the project. Existing framing conditions may not be fully visible before work begins. The proposal should explain how concealed concerns will be documented and how additional work would be authorized.
Account for the changed roof geometry
Tile can alter the relationship between the roof surface, fascia, gutters, walls and penetrations. Flashings and accessories designed around a shingle profile may need different details. Discuss eave support, ridge appearance and transitions at lower roof sections before approving the design. A material sample helps with appearance, but it cannot show every construction consequence of the change.
Compare complete alternatives
Ask for a scope that separates structural or deck work, weather layers, tile, flashings and associated edge work. Identify which existing accessories will remain and which will be replaced. If the decision is between staying with shingles and converting to tile, compare both options using the same roof area and known conditions. Keep permitting, documentation and finish restoration visible in the comparison. The useful outcome is a defined assembly that suits the property, rather than an unsupported promise that one material is always the best choice for every South Florida home.
Can the existing gutters remain?
Sometimes, but the proposed tile edge and runoff path need to be compared with their position and condition. Include gutter adjustments in the design discussion early. Leaving that decision until the new tiles are installed can make an otherwise straightforward conversion harder to finish coherently.
