Roofing & Cover in Luxembourg

In Luxembourg, roofers and carpenters work on single-family homes as well as apartment buildings, in new construction and in renovation alike. A roofer listed in the Vert.lu directory must hold an autorisation d'établissement issued by the Ministry of the Economy and be registered with the Chambre des Métiers or the Chambre de Commerce, a legal requirement for running a trade business in the country.

Wall insulation, roof insulation or window replacement can be subsidised per square metre under the Klimabonus renovation scheme, with an agreement in principle required before works start. Applications go through MyGuichet.lu, and the company carrying out roofing work must supply the technical documents required for the file; ask it to confirm eligibility before you sign anything.

Before appointing anyone for roofing work, check the company's autorisation d'établissement, ask for a detailed quote that separates materials, labour and ancillary costs, and compare at least two or three proposals: in Luxembourg, price, lead times and warranties for the same job often vary considerably.

Vert.lu compiles companies from public sources (trade register, Chambre des Métiers) as well as information companies submit themselves; requesting a quote through Vert.lu remains free and without obligation, the contract and the execution of the work being the sole responsibility of the company you choose.

Roofing: roof covering, framework, flashing and waterproofing

What this category covers

The roofing category groups companies that work on the upper envelope of your home: roof covering (tiles, slate, sheet metal), timber roof framework, flashing and sheet metal work, flat roof waterproofing, gutters and downpipes, roof windows, moss removal and cleaning, and roof insulation fitted under the rafters or on a flat roof.

This work affects the structure and watertightness of the building. It requires the precise skills of a roofer or carpenter, sound knowledge of working-at-height safety rules, and often coordination with other trades: an electrician for solar panels, a joiner for roof windows, an insulation specialist for the loft.

This category does not include the installation of the solar panels themselves, which falls under a solar installer, nor facade work unrelated to the roof. A full renovation project may nonetheless combine several of these categories.

Roof windows occupy a special place: fitting or replacing them involves both roofing work, for the watertightness around the frame, and joinery, for the product itself. Most roofing companies offer this service in a single visit, which simplifies planning for the homeowner.

Gutters and downpipes are sometimes overlooked even though they play an essential role in protecting the facade and foundations. Regular maintenance, including clearing leaves and checking fixings, prevents overflows that end up damaging load-bearing walls.

Roof covering and materials

Roof covering refers to fitting or replacing the roofing material: clay or concrete tiles, natural or synthetic slate, steel sheet panels, green roofs. The choice of material depends on the style of the house, communal rules that can be strict in protected zones, and budget.

Roof framework

The roof framework is the timber structure that carries the covering. It may need a localised repair after water damage, reinforcement when converting a loft, or a full replacement in case of decay or insect damage.

Flashing, gutters and waterproofing

Flashing covers the metal finishing elements: valleys, ridges, and seals around chimneys and roof windows. Gutters and downpipes drain rainwater and must be sized correctly. On flat roofs, a waterproofing membrane replaces traditional covering and requires specific know-how.

Roof windows and natural light

Fitting roof windows significantly improves natural light in a converted loft and is often planned as part of a loft conversion. Beyond the light gained, correctly sealing around the frame is the critical point: a poorly finished flashing membrane is one of the most common causes of later damp damage in the loft.

When insulating the roof from inside or outside, extra care around the roof window reveal is worthwhile, since thermal bridges can form there and noticeably reduce the overall performance of the insulation.

When to call a professional

Some signs should not be left unattended. A damp stain on the ceiling, visible water infiltration during or after rain, tiles displaced or broken after a storm, thick moss retaining moisture, or a roof framework showing mould traces or a musty smell all call for a quick assessment by a roofer.

Climbing onto a roof without proper equipment is dangerous. Professionals have the scaffolding, safety lines and training needed to work safely at height. This safety aspect alone is reason enough not to improvise a repair yourself, even one that seems minor.

Some work is also subject to administrative requirements. A change to the roof visible from the street, a change of covering material, raising the roof, or adding roof windows may require a communal building permit. Your commune's urban planning department can tell you whether your project is affected before any work begins.

If you are planning a solar panel installation, coordinating with the roofer beforehand is worthwhile: the condition of the covering and framework should be checked before panels are fitted, and some structural reinforcement may be needed. Planning this step ahead avoids having to remove recently installed panels to redo the roof underneath.

Finally, selling or renting a property requires an energy passport. A poorly insulated or damaged roof weighs on this rating and can slow down a transaction. A roof assessment before a sale helps anticipate this point.

A roof neglected for several years loses value much faster than one maintained regularly. An annual visual check, ideally after winter, helps spot a cracked tile or a worn flashing seal before the problem worsens and reaches the framework.

After a heavy storm with hail or strong wind, a quick visual check from outside is worthwhile even if no obvious problem is visible. Minor damage to tiles or flashing is often invisible from below and only shows up months later as a damp mark on the ceiling.

How a typical project runs

A roofing project generally follows the same broad steps, whether it involves a one-off repair or a full re-roofing. The exact order can vary slightly from one company to another, but the underlying pattern of site visit, quote, securing the site, execution and final inspection stays the same for almost every project.

Site visit and assessment

The roofer visits to inspect the roof, ideally from inside the loft and from outside. They assess the condition of the framework, covering, existing insulation and waterproofing. This visit usually takes between thirty minutes and an hour.

Detailed quote

The quote sets out the materials, surfaces, nature of the work, timeline and warranty terms. Comparing several quotes for equivalent work remains the best way to judge how serious an offer is.

Scaffolding and site safety

Before any work at height, compliant scaffolding is erected around the house. Setting it up and taking it down usually takes half a day to a full day depending on the building's layout.

Removal and installation

The old covering is removed, the framework inspected and repaired if needed, then the underlay, any insulation and the new covering are fitted. For a standard house roof, this phase typically takes a few days to two or three weeks depending on the scale of the work and the weather.

Final inspection

At the end of the job, a final inspection checks that the work matches the quote: watertightness, flashing finishes, rainwater drainage, and site clean-up. This is the time to flag any snags before settling the final payment.

Preparing the site as a homeowner

A few simple steps make the project run more smoothly. Let your neighbours know if scaffolding will occupy part of the public pathway, and check with your commune whether a temporary permit is needed to use the pavement. Clear the area around the house to make access and parking easier for site vehicles.

Indoors, protect any converted loft space and dust-sensitive items, especially during the removal phase. If insulation work is planned, clear the space under the rafters so tradespeople have full access.

Also ask about weather-related delays: some roofing work cannot be carried out in rain or strong wind, which can extend the project beyond the initial estimate.

Also clarify beforehand who is responsible for temporarily covering the roof if work has to stop overnight or when rain is forecast. A serious company plans for this protection from the start rather than improvising it only when needed.

What drives the price

The cost of a roofing project varies significantly depending on several factors, and no fixed amount can be given without a quote. The roof surface to be treated is the first factor: the larger the surface, the higher the overall cost, even though the cost per square metre may decrease.

The complexity of the roof plays an important role: the number of roof faces, dormers, chimneys, valleys and complex cuts all increase the amount of work. Site access also matters: a detached house with easy scaffolding access generally costs less to work on than a terraced house in a town centre.

The choice of covering material has a strong impact on the budget: natural slate, clay tile, concrete tile or steel sheet differ both in purchase cost and lifespan. The condition of the existing framework is another key factor: a sound framework limits costs, while a partial or full replacement increases them significantly.

The desired level of insulation, whether roof windows need to be fitted, and whether flashing and gutters need to be fully redone also factor into the calculation. The season has an impact too: roofers are often busier after winter and following storm peaks, which can extend waiting times.

Building height and roof pitch also affect the cost of scaffolding and material handling, particularly for multi-storey houses or sloped sites. If an assessment reveals woodworm or fungal damage, treating the framework adds further cost.

Any price range given before a quote remains an indicative range. Only a site visit and a detailed quote can provide a reliable figure for your project.

Grants and subsidies

Several schemes exist in Luxembourg to support roof insulation and energy renovation work. The Klimabonus applies in particular to roof insulation, one of the most effective measures for reducing a home's heat loss.

The Klimabonus Wunnen, which replaced the former PRIMe House programme in 2022, covers energy renovation more broadly, including when it is combined with roofing work. Additional communal grants may also be available depending on your municipality.

A reduced housing VAT rate of 3 % (TVA logement) may apply to certain renovation work in a main residence, under conditions. These mechanisms regularly change in terms of amounts, caps and eligibility conditions.

Vert.lu does not communicate specific amounts, as these change according to current regulations. For up-to-date amounts, caps and procedures, consult guichet.lu, myenergy.lu or klima-agence.lu, or contact an energy advisor before signing a quote if you plan to apply for a grant.

How to choose the company

Check that the company holds an establishment authorisation (autorisation d'établissement) issued by the Ministry of the Economy for roofing or carpentry work. This authorisation confirms the professional qualification required for this type of work.

Ask for several detailed and comparable quotes: same materials, same surfaces, same included services. A vague quote, or one noticeably cheaper than the others, deserves further questions before you sign.

Ask about the warranties offered, particularly on watertightness and structure, as well as the company's insurance in case of damage during the project. Also ask for references from similar projects completed recently in the region.

The company's availability and ability to respond quickly in an emergency, for example after a storm, is a criterion not to overlook, especially if your roof is old or already weakened.

Common mistakes to avoid

Delaying a repair after noticing infiltration is the costliest mistake: water seeping into the framework can cause structural damage far more expensive than the initial fix.

Hiring a company without an establishment authorisation or verifiable references exposes you to poor workmanship that is hard to have corrected. Likewise, accepting a quote without a breakdown of materials and surfaces makes any later comparison or claim difficult.

Forgetting to check whether a communal building permit is needed before changing the exterior appearance of the roof can lead to administrative complications, or even a restoration order from the commune.

Neglecting coordination between trades, for example installing solar panels before checking the condition of the covering underneath, causes avoidable extra costs if the matter is not handled in the right order.

Accepting an unusually low quote without checking exactly what it includes often leads to extra charges during the project, for instance for disposing of the old covering or for unexpected repairs to the framework that were not part of the original offer.

Frequently asked questions

What must a roofer be able to prove in Luxembourg?
An autorisation d'établissement issued by the Ministry of the Economy and registration with the Chambre des Métiers or the Chambre de Commerce. These are the legal requirements for running a trade business in Luxembourg; ask for them before signing anything.
Is there a state subsidy for roofing work?
Depending on the project, the Klimabonus can co-fund roofing work; amounts depend on the technology and the building, and applications go through MyGuichet.lu.
What should a quote for roofing work include?
A detailed quote separates materials, labour and ancillary costs, and states the lead time and the warranty. Always compare at least two or three quotes before deciding.
How does Vert.lu select the roofers and carpenters in its directory?
Listings are compiled from public sources (trade register, Chambre des Métiers) and from information submitted by the companies themselves. Requesting a quote through Vert.lu is free and without obligation.
Do I need a permit to redo my roof in Luxembourg?
It depends on the type of work. A like-for-like replacement generally does not require a permit, but a visible change to the roof, a change of covering material, or adding roof windows may require a communal building permit. Check with your commune's urban planning department before starting.
How long does a re-roofing project take?
For a standard house, a full re-roofing typically takes a few days to two or three weeks, depending on surface area, roof complexity and weather conditions. A one-off repair, such as replacing a few tiles, is usually done in a day.
Show more questions
What signs indicate the roof should be checked?
A damp stain on the ceiling, water infiltration after rain, tiles displaced or broken after a storm, thick moss, or a musty smell in the loft are signals that call for a quick assessment by a roofer.
Can solar panels be installed on an old roof?
It is possible, but it is recommended to have the condition of the covering and framework checked before installation. Coordinating between the roofer and the solar installer avoids having to remove recently fitted panels to redo the roof underneath.
What grants exist for roof insulation?
The Klimabonus Wunnen covers roof insulation, among other things, and additional communal grants may exist depending on your municipality. Amounts and conditions change regularly: check guichet.lu, myenergy.lu or klima-agence.lu for up-to-date information.
How can I check that a roofing company is reliable?
Check that it holds an establishment authorisation from the Chambre des Métiers, ask for references from recent projects, and compare several detailed quotes covering the same materials and surfaces.
Is moss removal enough to protect a roof?
Moss removal reduces surface moisture retention, but it does not fix a watertightness issue or an already damaged framework. A full assessment is still needed if signs of infiltration are already visible.
What happens after I submit a request on vert.lu?
Your request is forwarded to roofing companies matching your project and location. You then receive quotes directly from them and freely choose which company you want to move forward with.
