For businesses buying enquiriesRoofing leads in the Netherlands

For roofers who want enquiries for planned roof renovation, replacement or substantial repairs.

Which enquiries you receive

The applicant wants a roof renovated, replaced or substantially repaired. The roof type, the work and access have been discussed by phone. This concerns planned work, not an urgent leak.

Enquiries for planned roof renovation, replacement or substantial repairs.

What we check by phone

We have spoken to the applicant about the project, timing and agreed criteria. Stated budgets and measurements remain estimates unless specified otherwise.

  • Owner or authorised decision-maker
  • Roof type and work identified
  • Estimated roof area
  • Access and site situation discussed
  • Project planned within 3 months

What the enquirer states

These details are the enquirer's own indications and are marked as such in the brief.

  • Roof type: flat or pitched, and the current covering
  • Work wanted, for example replacement or renovation
  • Estimated roof area
  • Age of the roof, where known
  • Access and height of the building

What you do not receive

  • Urgent leaks and emergency repairs
  • Minor repairs such as a single tile
  • Tenants without the owner's permission
  • Projects outside the agreed service area

Please note: Klantwerf does not supply emergency enquiries and does not promise the applicant a date for work or inspection.

Service area

You choose postcodes or municipalities. We confirm per region whether enquiries are feasible; without that confirmation we promise no volume or delivery time.

Exclusive, and what that means

Klantwerf supplies the same enquiry to one buyer. The applicant may independently contact other providers.

No. You receive a qualified enquiry. Your business handles the quotation, sale and delivery of the work.

Something wrong with an enquiry?

Report incorrect details, a duplicate or a mismatch with the agreed criteria within 7 calendar days. Valid claims receive a replacement or credit after review. Terms are agreed before you start.

Valid reasons

  • Incorrect or non-existent contact
  • No genuine enquiry
  • Outside the agreed service area or criteria
  • Duplicate Klantwerf enquiry for the same project and the same buyer within 90 days

Not a valid reason

  • The enquirer later changes their mind
  • No contract or sale results from the enquiry

Is the enquirer unreachable after delivery? Report it with a short description of your attempts; we review each case individually. As a guideline: three reasonable attempts over two working days, and never continuing after an objection.

A valid report leads to a replacement or a credit, as agreed in advance. Not both. Media bookings follow their own cancellation terms.

Frequently asked questions
