Offering a new roof covering: clay or concrete tiles?

An owner wants a new roof covering. A clay tile and a concrete tile lie on the table during your discussion. They like both but do not yet know what their choice would actually order. Your roofing business has a concrete proposal task: turn two material ideas into identifiable, project-confirmed models with a complete scope of work. A price for one roof tile is not enough for that decision.

This guide is for roofers, carpenters and roof renovation businesses working in Germany. It helps with material and model selection for a defined reroofing project. The responsible specialists assess suitability and required planning. It contains no laying or design calculation instructions. Two expressly fictional cases show different customer decisions without claiming actual sales success or the general superiority of one material.

Start with the roof appearance the customer wants

Ask what the owner likes about the two samples. Do they mean the colour, finish, profile or effect across a larger covered area? A material name alone does not answer that. A customer may say “clay tile” while mainly imagining a particular shape. Record that idea specifically. It starts the selection process but is not yet confirmation that the product suits the building.

When using pictures, identify the model and finish shown. A single sample and a complete roof photograph give different impressions. Relate both to the actual proposed variant when using them for advice. If an illustration shows another finish, explain the difference. The owner should develop their idea around their own proposal, rather than discover after choosing that the illustrated roof used a different product.

Distinguish the material from the actual model

The current BMI/BRAAS overview of roof tiles distinguishes clay tiles from concrete tiles. It shows different models and finishes within each group. For proposal work, this means that choosing a material does not yet identify the configuration ordered. The customer needs the specific model name and corresponding variant that your business can actually offer.

The manufacturer page names, for example, the Opal plain clay tile and the Frankfurter Pfanne concrete tile. Such examples illustrate different roof appearances. They are not a recommendation here to order either product without project assessment. Use the actual selected product name in your proposal. A general “tiles of your choice” leaves unclear which configuration was costed and what change a later selection would cause.

Have the specific alternative confirmed by specialists

Give your responsible specialist the proposed models and existing project documents. They determine which suitability questions need clarification for this roof and what additional planning is required. A general statement about a material does not replace that assessment. Nor does the old covering’s material provide blanket approval for a new model. Sales needs the specific finding that can support further proposal work.

Record which alternative has been confirmed and which has not. If a proposal lacks a necessary basis, identify the gap. Do not present it as ready to execute alongside a confirmed option. A customer can initially be interested in further assessment without ordering an approved product. That distinction keeps the consultation useful and prevents the proposal from conveying more certainty than the actual documents support.

Do not adopt blanket weight or price rules

The owner may have read that a certain material is inherently heavier or cheaper. Bring the discussion back to the intended models and roof. Your specialists assess the project information required. Purchasing establishes the current price of the actual configuration. A general material rule replaces neither specific specialist confirmation nor your own costing. An attractive unit price does not explain the completed renovation contract.

Avoid blanket service-life, frost or protection promises taken from product advertising too. If a particular property matters to the choice, your business needs the relevant current document and its actual scope. This guide compares no warranty programmes and gives no market prices. You can explain colour, appearance and confirmed services clearly without deriving a general guarantee for the entire building from a material choice.

Compare the same renovation area

Define the roof areas to be renewed and those remaining in place. Use the same location descriptions and confirmed starting area for the comparison. A proposal for the main slope cannot be compared solely by total price with one also including an extension. Identify that difference before the customer sees it as a material-price difference. Actual scope remains the shared basis of the comparison.

If adjacent areas need different consideration in planning for one model, have that allocated professionally and describe the affected service. This does not require installation instructions. The customer must understand why two complete proposals may have different scopes. Use the same clear descriptions for shared work. Put differences where they actually affect the service offered.

Cost the roof system rather than just the field tile

The manufacturer overview describes tiles as part of a roof system. This gives you a practical proposal task: have the items needed for the confirmed variant established completely. Which model-specific pieces and supplementary components belong to the planned scope? Which does your business obtain through which supply route? Specialists determine the required products. Sales should then explain the same complete service that was costed internally.

A low field-tile price cannot replace a missing overall scope. Separate materials from labour, preparation and other services actually required. Allocate shared work transparently and avoid counting it twice. Use your own quantities and current supplier quotations. If an item remains open, identify it precisely and clarify it before the corresponding commitment. The comparison then relates to the completed result actually offered.

Explain what the additional price actually covers

When two confirmed variants are available, explain why their totals differ. The difference may concern the chosen model and finish or the associated confirmed scope. Show the actual differences in your proposal. Do not assume that a higher price automatically means longer service life or better suitability. Those are separate claims that a price comparison alone does not establish.

If the owner brings another price sheet, ask which product and scope it names. You can explain any missing information. That does not allow you to confirm or disprove another provider’s incomplete costing. A helpful answer identifies the information still needed for comparison. Your own scope remains clearly explainable even when another total cannot yet be assessed meaningfully.

Link selection to a clarified purchasing position

Before making the corresponding customer commitment, clarify with your supplier which exact variant is offered for the project and on what supply basis. A model in a general online catalogue is not a confirmed delivery commitment for this project. Record which finish or colour the current information concerns. Your team needs an unambiguous basis so it does not prepare a different variant from the one chosen by the customer.

If the supplier suggests an alternative, do not silently pass it on as an equivalent replacement. Have the specialist allocation and customer preference for that actual new configuration clarified. A familiar material name does not answer the question about the altered appearance. Further work uses the confirmed selection and current scope. Keep the earlier version as history, rather than making it the basis for a different order.

Fictional case: a particular clay tile is selected

Suppose an owner wants an appearance they recognise in a displayed clay tile model. Your business has the specific variant assessed for the project and establishes the full scope. A confirmed concrete-tile alternative is explained for comparison. Both proposals cover the same renovation area. The owner can now judge each configuration and your own offered services.

In this entirely invented case, they select the clay tile because its design suits their preference. The proposal version identifies the model, finish and associated costed scope. No material superiority or particular future property value is claimed. The case shows a concrete product choice following specialist clarification. A desired appearance becomes an understandably described proposal for this building.

Fictional case: the concrete-tile variant fits the choice

In a second invented case, an owner is interested in the specific concrete-tile variant shown. Your team has clarified its suitability and included the associated system completely. A similarly confirmed clay-tile option remains a real comparison. Explain appearance, finish and actual service differences using both proposal versions. The customer decides from these specific choices without needing a general material ranking.

In the example, she wants to pursue the concrete-tile variant. Before a corresponding order, link the selection to the current purchasing position and agreed proposal version. Other models discussed earlier remain unordered. The case promises neither lower total costs nor a particular service life. It shows how your business can support another distinct customer choice clearly without bypassing the project’s technical limits.

Record the selected variant unambiguously

After the discussion, the next person in your business should recognise the same selection as the customer. Link roof area, model, finish and current proposal version to the confirmed documents. If only further sampling or assessment has been agreed, name that status. A shortlist is not an order for every product shown. The record should show exactly which decision has been made and which is outstanding.

For a later change request, check the affected item. A different colour or model may need new purchasing information and further specialist allocation. Have the specific change assessed and preserve the earlier position. A colleague covering for you can then explain why an old price sheet does not automatically belong to the new selection. Documentation helps the customer and your team continue with the same actual proposed variant.

Check the selection from the customer’s perspective

Finally, ask the owner to name the chosen covering in their own words. Do they recognise the actual model and finish rather than just “clay” or “concrete”? Do they know which roof areas and other services your total includes? Add the specific explanation missing. The customer is not expected to calculate materials. They should understand the completed scope they are selecting from your business.

Then read the proposal description with the responsible specialist and the person preparing the office work. Do the confirmed variant, quantity basis and customer choice agree? Is an open point recognisable as open? The owner then has a concrete basis for their renovation order. Your business can offer exactly the professionally clarified and transparently costed service. The customer decides whether to commission it from that proposal.
