Roof renovation in Aix-les-Bains.

In Aix-les-Bains, as everywhere in Savoie, the roof is your home's first line of defence against a demanding Alpine climate. Between the weight of snow in winter, repeated freeze-thaw cycles, heavy rain and temperature swings, a roof covering is under constant strain. Tiles crack, the underlay ages, fixings loosen: over the years, watertightness deteriorates and the first leaks appear.

Several signs of wear should alert you: broken, slipped or porous tiles, traces of damp or water stains in the loft, moss and lichen that hold water, a sagging ridge line, or overflowing gutters. The longer a roof is neglected, the more the damage spreads to the roof structure, insulation and walls — and the higher the bill. Acting early means redoing a roof quickly before the problem becomes structural.

Beyond watertightness, an outdated roof is also a major source of heat loss: up to 30% of the heat in a poorly insulated house escapes through the roof. Taking advantage of re-roofing to redo the insulation means greater comfort in summer and winter and lastingly lower bills.

Many homeowners put off their works for fear of a never-ending project. That is a misconception: a roof can be redone very quickly as long as the works are well prepared. Everything happens beforehand. We first carry out a precise survey of the covering and roof structure, we cost the works, then we order and have all the materials delivered before work starts. On the day, nothing is missing: the team gets straight to work with no downtime.

Stripping the old covering and laying the new one progress section by section, never the whole roof at once. This method keeps part of the roof protected at all times and makes the house watertight in just a few days on a standard roof. If bad weather is forecast, safety tarpaulins are always planned: your home is never left exposed.

For a complete tiled re-roof on a detached house, allow generally one to two weeks on site, scaffolding included — much less for a localised repair. We plan each stage with a clear schedule, limit disruption and coordinate the trades (roofing, roof structure, leadwork, insulation) to meet deadlines. This controlled approach to site work is also the one we apply to house renovation in Aix-les-Bains.

Tiled roofs — the most common roof covering in the Aix-les-Bains area. Interlocking tiles, plain tiles or Roman tiles: we strip the old covering, fit a high-performance breathable (HPV) underlay, and lay new tiles suited to the Savoie climate. A tiled roof remains the most durable solution and the one most respectful of local character.

Slate — for steeply pitched roofs and heritage character, we re-roof in natural slate, in line with best practice and the architectural requirements in protected areas.

Zinc and steel roofing sheets — on low-pitched roofs, extensions or contemporary architecture, zinc and steel roofing sheets offer lightness, watertightness and longevity. We also handle all the associated leadwork: valleys, flashings, cladding.

Flat roofs and waterproofing — garages, extensions, outbuildings: we carry out roof waterproofing on flat roofs using membranes or bituminous systems, redoing upstands and outlets for reliable, lasting watertightness.

Timber roof structures — there is no good roof covering without a sound roof structure. We survey and repair damaged roof structures and coverings: timber treatment, replacement of damaged rafters or purlins, strengthening the structure before the roof is re-laid.

Redoing your roof is the ideal time to deal with insulation. When the covering has been removed, accessing the roof structure and loft becomes simple and cost-effective. Rather than working twice, re-roofing and roof insulation are combined in a single project — which reduces the overall cost and maximises the energy gain.

Two approaches are possible depending on your house: loft insulation (blown or panels, ideal for unconverted lofts) and under-roof insulation using sarking, fitted from the outside above the rafters, which eliminates thermal bridges without reducing the living space. The latter is particularly suited to converted lofts and chalets.

As soon as re-roofing is combined with insulation, the works become eligible for energy renovation grants (MaPrimeRénov', CEE, eco-PTZ). As an RGE-certified company, we prepare the grant applications for you.
