Why choose Avenir Renovations?
When and why renovate your roof in Leuven?
Stop leaks before they spread
A cracked tile, a detached flashing around the chimney, a cracked flat roof membrane: water always finds its way. It first damages the insulation, then the structure, and finally the ceilings.
The later the intervention, the higher the bill. Timely inspection often allows for a targeted repair rather than a complete refurbishment.
Finally insulate from above
An uninsulated roof is one of the primary sources of heat loss in a house. Replacing the covering is the best time to insulate it properly from the outside, without touching the inhabited rooms.
For a property purchased with an E or F label, this is generally the most effective measure to move towards a D label. Our roof insulation price simulator provides a first benchmark.
Treat a roof containing asbestos
Many houses built before 2001 have slates or corrugated sheets made of asbestos-containing fiber cement on the main roof, a garage, or an annex. In Flanders, it is prohibited to clean, cover, or attach solar panels to them, and the regional goal aims for their removal by 2034.
Roof renovation is the opportunity to have them removed properly by a specialized company before installing the new covering.

The advantages of a roof renovation with Avenir Renovations
Entrusting your roof to Avenir Renovations guarantees comprehensive support, from diagnosis to finishing touches. Our expertise ensures secure, durable work tailored to your home.
Condition of the covering, the zinc work, the framework, the insulation, and the under-roof: everything is inspected.
You receive a written report, with interventions classified by degree of urgency.
Resistance to frost, wind, humidity, compatibility with neighboring buildings: the material is chosen to last and to integrate.
Tile, slate, or zinc: each option is presented with its strengths and limitations.
Scaffolding, protections, waste disposal, asbestos management if necessary: everything is planned.
In the city center, permission to occupy public space for scaffolding is requested well before the first day.
The work is covered by a ten-year guarantee. You also receive technical data sheets for the materials and photos of the stages that are no longer visible once the roof is closed: under-roof, insulation, connections.
This file is used for your insurance, your notary during a sale, the EPC certifier, and for claiming a grant if you are entitled to one.
What is the price of a roof renovation in Leuven?
Chosen covering, surface area, slope, access, and condition of the framework: these determine the price. Our roof renovation price simulator guides you. Prices including VAT calculated at 6%, rate reserved for residential buildings over ten years old.
| Type of work | What affects the price | Indicative price including VAT |
| Roof covering renovation with under-roof | Type of tile, slope, battens to replace | 110 to 180 € / m² |
| Renovation of natural slate covering | Origin of the slate, complexity of the roof | 150 to 250 € / m² |
| Roof renovation with external insulation | Insulation thickness, edges and gutters to adapt | 220 to 350 € / m² |
| Flat roof waterproofing renovation with insulation | Roofing or EPDM, upstands, drains | 110 to 190 € / m² |
| Replacement of zinc gutters | Length, number of downspouts, access | 60 to 120 € / linear meter |
| Removal of asbestos sheets or slates | Surface area, access, framed disposal | 25 to 60 € / m² |
| Scaffolding for a semi-detached house | Height, duration, occupation of the sidewalk | 1,500 to 4,000 € |
On-site, the covering, zinc work, and framework are inspected, and the presence of asbestos is checked. The estimate is then established item by item, including scaffolding and disposal.
Example: for a semi-detached house in Kessel-Lo with seventy square meters of tile roof, a complete renovation with new under-roof, internal insulation, and new gutters often costs between 14,000 and 22,000 euros including VAT.
Procedures and grants for roof renovation in Leuven in 2026
When is a permit required to redo your roof?
A like-for-like replacement is generally exempt from a permit. A visible change in material from the street, a change in slope, or a dormer requires verification, or even an omgevingsvergunning. For a building listed in the heritage inventory in the historic center, the choice of materials may also be regulated.
The grant for an insulated roof
In Mijn VerbouwPremie, roof renovation is only supported if it is accompanied by insulation, and only for owner-occupiers in income categories 3 and 4 since March 2026. Other households retain the VAT at 6% on a property over ten years old and, for categories 2 to 4, access to Mijn VerbouwLening.
The removal of asbestos
Asbestos-containing fiber cement sheets and slates must be removed according to strict rules before a new covering is installed. For large areas, this removal is entrusted to a specialized company. For small quantities, the regional waste intermunicipal, EcoWerf, organizes a collection for individuals.
The occupation of public space
In a narrow street in the center of Leuven, scaffolding or a container often occupies the sidewalk. A permit from the City is then necessary, sometimes requiring signage. We submit the request and integrate it into the schedule.
Duration and special cases of a roof renovation
The duration of a roof refurbishment
For a semi-detached house, expect one to three weeks depending on the area, insulation, and weather. The roof is never left open without protection in the evening.
The schedule allows for rain: only the area that can be closed the same day or covered with a reliable tarp is uncovered.
Identifying asbestos in slates
Fibrocement slates installed before 2001 often contain it. If you recently purchased the house, the asbestos certificate mentions it. Otherwise, a sample analyzed in a laboratory clears up any doubt.
A flat roof that leaks
A localized leak around a drain or a rise can be repaired. If the membrane is cracked everywhere or if the insulation is waterlogged, a complete refurbishment is more reasonable.
An inspection after a heavy storm, when the leak is still visible, greatly helps to locate the water entry point.
The condition of the framework
The rafters, purlins, and trusses are checked during the removal of the covering. Parts affected by moisture or insects are replaced or reinforced before the insulation is installed. A healthy framework is preserved.
Frequently asked questions about roof renovation in Leuven
How long does a tile or slate roof last?
A terracotta tile roof often lasts fifty years or more, natural slate even longer. It is usually the battens, under-roofing, and zinc work that require renovation, generally after thirty to forty years.
Do you need to redo the entire roof for a leak?
No, not if the covering is generally sound. A broken tile, a detached flashing, or a pierced valley can be repaired locally. When leaks multiply or the under-roofing is absent, a complete refurbishment becomes more economical in the long run.
What material should be chosen for a roof in Leuven?
In most neighborhoods, terracotta tile remains the most common choice and the most consistent with neighboring houses. Slate is suitable for manor houses and older buildings, while zinc and EPDM are used for flat roofs and extensions.
What to do after a storm that damaged the roof?
First, have a temporary tarp installed to limit infiltrations, then take photos of the damage for your insurance. A complete inspection then checks that the visible damage does not hide other weaknesses, such as a torn under-roofing.
Have your roof inspected before winter
Autumn storms reveal the weaknesses of a roof. A diagnosis in September or October allows time to intervene before the strong winds.
