What these terms cover

Every survey, quote and job carried out by Dakrenovatie Haarlem within the service area shown on this site. Where something differs, it is stated in the quote, and in that case the quote takes precedence over this text.

The survey and the report

The survey is free and happens within the deadline stated on the page for your town. The report, with a photo per roof plane, the condition of the deck and the insulation calculation, is yours and you may use it as you wish, including to assess somebody else's quote. There is no obligation to do anything with it.

How a job comes about

Counting from the survey, the quote reaches you inside 3 working days and then stands for thirty days. A job comes about once you confirm that quote in writing or by email. Verbal commitments about extra work or scheduling take effect only once confirmed in writing, and that is in your interest rather than ours.

Extra work and what comes out from under the covering

What sits under the roof covering only becomes visible once it is off. Repair of a damaged deck therefore appears in the quote as a unit rate per square metre, so the rate is known in advance and only the quantity remains open. Any other extra work is put to you first and carried out only after you agree, even when the scaffold is already up.

Scheduling and weather

We never open more roof surface than can be closed again the same day. In rain, frost or wind force seven and above, no work is done on an open roof. Weather delay moves the schedule and changes nothing about the agreed amount; if it extends the work by more than five working days, you hear as soon as we know.

Permits and conservation assessment

During the survey we check whether your address needs a permit or a conservation assessment and put that in writing. Filing the application is a separate instruction: the applicant on the form is whoever owns the building, so we only file once you ask us to. How long a municipality then takes is outside our control and does not count towards the agreed completion period.

Payment

In instalments that run alongside the work: part when work starts on site, part when the roof plane is completed, and the balance after handover. The exact schedule is in the quote, stating what each instalment is tied to. Nothing is paid in advance for work not yet carried out. Invoices carry a fourteen day payment term.

Guarantee

Counting from handover, what we laid carries 10 years of our own guarantee, next to whatever the factory puts on the material. Not covered: storm damage above force ten, damage caused by others who have been on the roof after handover, blockage by leaves or debris that was not cleared, and defects in a structure already flagged in the survey report at handover.

Cancelling

Cancellation is free up to ten working days before the planned start date. After that, materials already ordered and the reserved scaffold are charged, because both are committed by then. Tiles or slates specially ordered in a non-standard profile cannot be returned and are always passed on.

Liability

Where something goes wrong during the work and damage follows from it, we carry that damage up to the amount invoiced for that roof. Anything flowing on from it, such as lost rent or a business standing still, sits outside that ceiling; buildings and contents insurance covers that ground. One exception we impose on ourselves: a defect that was visible during the survey and that we left out of the report is ours to put right, and is never turned down as a pre-existing fault.

Complaints

Report a complaint about the work as soon as possible, and in any case within fourteen days of noticing the defect. We come and look before anything is repaired, so that what happened is on record. If we cannot settle it between us, a Dutch court decides; the law of the Netherlands governs everything set out above.

Which version applies

You are reading a translation kept for convenience. What binds either party is the Dutch wording, reachable from the footer of every page; where the two read differently, the Dutch sentence decides.
