01 Definitions and applicability
"DG Dakwerken" means: DG Dakwerken, established at Ambachtsweg 46, 2291 EX Wateringen, registered with the Dutch Chamber of Commerce under number 90829980.
"Client" means: the natural person or legal entity instructing DG Dakwerken to carry out work or provide services.
These terms apply to all quotes, agreements and work between DG Dakwerken and the client, unless otherwise agreed in writing.
General or purchase terms of the client do not apply, unless DG Dakwerken has expressly accepted them in writing.
02 Quotes and agreement
All quotes from DG Dakwerken are non-binding and valid for 30 days from issue date, unless stated otherwise.
An agreement is concluded as soon as the client accepts the quote in writing (e-mail is sufficient), or as soon as DG Dakwerken commences work.
Changes or additions to the agreement are only valid when confirmed in writing by DG Dakwerken.
03 Prices and additional work
Unless stated otherwise, prices include VAT and exclude any additional costs such as dump fees, permits or special transport.
If during execution it appears that additional work is needed, for example due to unforeseen damage beneath the existing roof covering — the client will be informed in advance. Additional work is only carried out after written approval.
If additional work cannot be approved in advance (for example in case of acute water penetration or emergency repair), DG Dakwerken has the right to carry out the work at a reasonable price and invoice it afterwards.
04 Payment
Invoices must be paid within 14 days of the invoice date, unless otherwise agreed in the quote.
For larger projects, DG Dakwerken may propose an instalment arrangement, for example 50% on commencement and 50% on completion.
If the client does not pay within the payment term, the client is in default by operation of law. DG Dakwerken may then charge statutory interest plus collection costs.
All supplied materials remain the property of DG Dakwerken until the full invoice has been paid (retention of title).
05 Execution and completion
DG Dakwerken carries out work to the best of its craftsmanship, in accordance with VCA standards and using quality materials from recognised suppliers (including Zinkunie partners).
Stated execution dates are target dates, not strict deadlines. Delay due to weather conditions, supply problems or force majeure does not entitle the client to compensation or termination.
The work is deemed completed as soon as DG Dakwerken has notified the client that the work is ready, or as soon as the client takes the work into actual use.
On completion the client receives a photo report of the work performed.
06 Warranty
DG Dakwerken provides a 10-year warranty on new or renewed roofing work delivered — full roof replacement, roof renovation or roof insulation — calculated from the date of the final invoice.
Repair work, including emergency repairs, leak sealing and partial repairs on existing roofing — is NOT covered by the warranty in subsection 1 of this article, because the underlying condition of existing roofing is often unpredictable.
The warranty covers correction of defects resulting from errors in execution or in the material supplied by DG Dakwerken.
The warranty lapses if: third parties have carried out work on the roof without DG Dakwerken's permission; the roof has been improperly maintained; damage has occurred due to extreme weather (storm above Beaufort 8, hail damage, lightning strike); or the roof is used for purposes other than originally agreed.
Alongside our workmanship warranty, the manufacturer's warranty on materials used applies — typically: bitumen 10-15 years, EPDM 20+ years, NedZink 30+ years, clay tiles 50+ years.
07 Liability
The liability of DG Dakwerken is limited to the amount paid out in the relevant case by the business liability insurance.
If for any reason no payment is made, liability is limited to a maximum of the invoice amount of the relevant assignment.
DG Dakwerken is not liable for indirect damage — such as lost profit, missed savings, consequential damage or business stagnation.
The client indemnifies DG Dakwerken against claims from third parties arising from incorrect information provided by the client about the structural condition of the roof or property.
08 Force majeure
Force majeure means, among other things: weather conditions that make safe roof work impossible (storm, black ice, heavy precipitation, extreme heat), strikes, illness of staff, supply problems with materials, transport disruptions, or government measures.
In case of force majeure, performance of the agreement is suspended until the force majeure situation has ended. If force majeure lasts longer than 60 days, both parties may terminate the agreement in writing without any obligation to pay damages.
09 Complaints, law and disputes
Complaints about work performed must be reported in writing to DG Dakwerken within 14 days of discovery — by e-mail to info@dgdakwerken.nl or by post to Ambachtsweg 46, 2291 EX Wateringen.
DG Dakwerken will respond to a complaint within 10 working days and strive for a reasonable solution.
Dutch law applies exclusively to all agreements between DG Dakwerken and the client.
Disputes that cannot be resolved by mutual consultation will be submitted to the competent court in the The Hague district.
