23 roofers & carpenters in Luxembourg

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.

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.

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.

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.

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.

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.

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.

Vert.lu is a lead platform: you describe your roofing project in a few minutes, and your request is forwarded to roofing, carpentry or flashing companies matching your criteria and location.

You then receive quotes from interested companies and remain entirely free to choose the one you want to work with, or to decline all offers.

Vert.lu does not carry out any work itself and charges no fee to the homeowner submitting a request. The service simply saves time by avoiding the need to contact each company individually.
