Toitures façades

Look for the diagnosis before the price: what the inspection found, which details are being replaced and why, and how flashings, valleys, penetrations, gutters and downpipes are treated. On facades, compare substrate repair, render or cladding build-up, insulation continuity and the treatment of sills and reveals rather than the surface rate alone.

Confirm access arrangements, scaffolding, edge protection and how long the building may stand partly open, along with the plan if the weather turns. Ask what happens if the structure or existing insulation proves to be damaged once the covering is lifted, since that is the most common source of variations. Guarantees, disposal of removed material and a final inspection with photographs are all worth listing.

Roof and facade work starts with an inspection: the state of the covering, flashings, gutters and, where accessible, the timber structure and insulation. Most damage traces back to water finding a path, at a valley, a chimney junction, a parapet or a blocked gutter, so a quote that identifies the entry point is more useful than one that only prices a surface.

Access shapes the schedule and cost, since scaffolding, edge protection and weather windows must be planned before work begins. Ask how the building is protected if the covering is opened, how rainwater is managed during the works, and which details, ventilation of the roof build-up, insulation continuity, render base coats, are specified. Clarify what remains accessible for future maintenance.

This category brings together the work that protects a building from the weather and shapes its outward appearance. On the roof side: roof windows, roof framing, roof covering, moss removal and roof cleaning, waterproofing, flashing and sheet metal work, green roofs, and timber frame treatment. On the facade side: cladding, render, facade waterproofing, facade insulation, facade painting, facade renovation and facade cleaning.

Roof and facade form a home's first line of defence against water, wind and frost. An untreated roof leak often ends up damaging the insulation, the timber frame and then the interior ceilings; a cracked facade lets damp settle into the walls. This work rarely suits DIY: the height involved, the exposure to weather, and the consequences of poor workmanship justify calling in a qualified company.

Any work on a roof, whether covering, framing or waterproofing, involves working at height and requires proper safety equipment and insurance: not a job to improvise. A roofer is also the right person to diagnose a leak, replace damaged tiles, or treat a timber frame affected by insects or fungus.

For facades, a professional is needed once the work goes beyond a simple repaint: crack repair, render restoration, cladding or external insulation all require assessing the substrate and choosing materials compatible with the existing structure, or risk later problems.

A roofing project starts with an inspection, often supplemented by a visit to the attic to check the condition of the frame and insulation. The quote then details the covering materials, flashing work and, if needed, scaffolding or fall protection. Replacing a full roof covering usually takes one to several weeks depending on the area and the complexity of the frame.

A facade project follows a similar path: assessing the substrate, treating cracks or damp, setting up scaffolding, applying render, cladding or paint, then finishing touches. A full facade renovation including external insulation is measured in weeks rather than days.

For roofs, the area, pitch, covering material, condition of the frame and accessibility of the site are the main factors. A hard-to-reach roof or one requiring complex scaffolding drives up labour costs regardless of material prices.

For facades, the area to be treated, the condition of the existing substrate, the finish chosen and whether external insulation is added strongly affect the price. A facade that needs damp treatment or structural repair before rendering costs more than a straightforward repaint.

Klimabonus Wunnen, which replaced the former PRIMe House programme in 2022, can support insulation work linked to a roof or facade renovation, subject to energy performance conditions. Exact amounts and terms are published on guichet.lu; they only cover the insulation portion of the project, not purely cosmetic work or covering alone.

Check that the company holds a business permit for roofing or facade work, along with professional liability insurance covering work at height. A proper quote details the materials, quantities, the type of scaffolding planned, waste disposal, and the timeline.

Compare quotes on a like-for-like basis: a lower price that leaves out scaffolding, protecting openings, or debris removal is not comparable to a complete quote. Describe your project on vert.lu and we pass it to companies in our directory specialising in roofing and facades in your area; those available will get in touch to arrange a visit, with no obligation.
