Decide whether existing roof tile can be reused

Identify what is actually installed

Start with safe ground-level photos of field tile, hips, ridges, rakes, eaves, and visible repairs. Look for manufacturer marks only on loose samples already available; do not climb onto the roof or lift installed tile. Gather invoices, permits, product brochures, and prior reroof records. Concrete and clay products can share a similar shape while differing in dimensions, interlocks, color blend, and accessory pieces. A contractor or tile supplier may need a physical sample to confirm the profile and current availability.

Separate condition from availability

A tile may look intact yet break during removal, handling, cleaning, stacking, or refastening. Ask the contractor how reuse candidates will be evaluated and how expected breakage will be carried in the bid. Count field tile separately from ridge, hip, rake, starter, and specialty pieces. Existing patches may contain mixed products. If the profile is discontinued, limited matching stock can affect which roof planes receive the best original tile and where a compatible transition or complete replacement should be considered.

Write the inventory plan into the proposal

The scope should assign responsibility for removal, sorting, palletizing or staging, weather protection, breakage tracking, supplemental tile, rejected material, and disposal. It should state whether tiles will be returned to their original planes or redistributed for a consistent appearance. Confirm how solar, skylights, chimneys, and changed roof details affect quantities. Reuse is not only a material choice; it changes labor, storage, schedule, and risk. Keep a written alternate for replacement tile so a shortage discovered during tear-off does not force an improvised decision.

• Photograph sample tiles beside a ruler and profile view
• Protect retained trim pieces from general debris
• Approve visible color-blend expectations before installation

Set a decision point after tear-off

No preconstruction count can remove all uncertainty. Agree on a checkpoint after enough tile has been removed and sorted to test the reuse assumptions. The contractor should report usable quantities by type, documented breakage, concealed roof changes, and the remaining need for matching material. The owner can then approve the planned distribution or a written alternate before installation locks in the appearance. Keep rejected samples until the decision is recorded when practical. This step prevents the first roof plane from consuming scarce trim or best-condition field tile needed elsewhere.
