The cost of a roof renovation depends mainly on roof size, roof type (flat or pitched), your choice of materials, the condition of the substrate, accessibility and any insulation. Because every roof is different, you always receive a free, no-obligation quote after a roof inspection.
What does the cost of a roof renovation depend on?
An honest answer to “what does a roof renovation cost?” unfortunately doesn’t come in the form of a single figure. No two roofs are alike: the surface area differs, the condition of the substrate differs and your wishes differ. What we can do is explain exactly which factors determine the price, so you understand why a quote only makes sense once we’ve seen your roof with our own eyes.
The most important price-determining factors are:
- Roof size (surface area in m²) — more square metres means more material and more labour hours. A 30 m² renovation is a completely different project from the 615 m² we tackled in Pijnacker.
- Roof type: flat or pitched — a flat roof in bitumen or EPDM calls for a different approach and different materials than a pitched tiled roof.
- Choice of materials — bitumen, EPDM, clay or concrete roof tiles: each material has its own lifespan, weight and price.
- Condition of the substrate and extent of damage — is the roof decking still sound, or is there wood rot? Hidden damage only shows up during inspection.
- Accessibility and scaffolding — a high or hard-to-reach roof requires scaffolding or an aerial platform, and that counts toward the total.
- Insulation — would you like to improve insulation at the same time? That lowers your energy bill, but requires extra material.
- Edge finishing, dormers and skylights — every detail around a penetration or edge requires extra craftsmanship.
Renovate or replace the whole roof?
A common question is whether a renovation is still enough, or whether the roof needs to be replaced entirely. The short answer: it depends on the condition of the structure underneath.
When a renovation is enough: if the roof structure and decking are still healthy and only the roof covering is worn out, renovating is often sufficient and more economical. For flat roofs we can in many cases overlay — a new bitumen layer over the old one. That’s faster, cleaner, better insulated and extra watertight.
When replacement is wiser: if the underlying structure has been affected by moisture or wood rot, or if the roof has already been repaired several times, a full replacement is often the better long-term choice. Read more about what that involves for replacing a flat roof or replacing roof tiles.
Why a quote only makes sense after an inspection
You could google an average price online, but such a figure tells you nothing about your roof. Only once we measure the surface on site, assess the substrate and check accessibility can we give you an honest, accurate figure. That’s why every renovation with us begins with a thorough roof inspection. We check the roof covering, the edge finishing, the penetrations and the woodwork, so no surprises crop up during the project.
A real-world example: 615 m² in Pijnacker
In Pijnacker we renovated a 615 m² flat roof. There we applied a double layer of mineralised bitumen using the overlay method: a new, high-quality layer over the existing roof covering. The result is a roof that can last for years again, insulates better and is fully watertight — without having to demolish the old roof first. Precisely because this project was so large, it shows how closely the final price relates to surface area, chosen material and approach. A similar 30 m² roof simply falls into a different category. See more of our work on the projects page.
Will a renovation save you money in the long run?
A well-executed roof renovation is an investment that pays for itself. You prevent roof leaks and follow-on damage to ceilings, insulation and contents, and with better insulation your energy bill drops. On top of that, we offer up to 15 years’ warranty on our roofing work, so you can rest easy for years. Postponing necessary maintenance almost always turns out more expensive than renovating in good time.

Frequently asked questions
In many cases, yes. If the roof structure and decking are still healthy and only the roof covering is worn out, a renovation usually suffices. For flat roofs we can often overlay: a new bitumen layer over the old one. Only when the underlying structure has been affected by moisture or wood rot do we recommend full replacement.
The most important ones are:
- Roof size (surface area in m²)
- Roof type: flat or pitched
- Choice of materials (bitumen, EPDM, roof tiles)
- Condition of the substrate and extent of damage
- Accessibility and required scaffolding
- Insulation and edge finishing
That's why we can only draw up an accurate quote after a roof inspection.
Yes. After a free roof inspection you receive a clear, no-obligation, tailored quote from us. Because every roof is different, that's the only honest way to determine the cost — an online ballpark figure tells you nothing about your specific roof.
A professionally renovated roof lasts for many years again. We offer up to 15 years' warranty on our roofing work. A renovation also prevents roof leaks and, with better insulation, can lower your energy bill.
