When should you renovate your roof?

Steps of your roofing project
At Avenir Rénovations Namur, every roofing project follows a clear method in five steps, from the initial inspection to the final reception. This approach ensures safety, durability, and impeccable quality for your roofing.
Our roofing interventions (Namur & province)
At Avenir Rénovations Namur, we work on all types of roofs, sloped or flat, with complete expertise. From roofing to zinc work, every detail is mastered to ensure durability, waterproofing, and energy performance.
- Clay/concrete tiles: durable, numerous shades, slight variations in appearance depending on the range.
- Slates (natural or fiber-cement): elegant finish, excellent frost resistance; regular format.
- Standing seam zinc: contemporary aesthetic, low maintenance, ideal for low slope.
Implementation details: batten/counter-batten, breathable under-roof screen, wind-resistant fastening, under-roof ventilation (drain entry/ridge exit).
- Bituminous or synthetic membranes depending on the substrate, in warm roof (insulation above the substrate, careful vapor barrier) or inverted.
- Treatment of parapets, upstands, drainage (outlets, scuppers) and slopes (≥ 2%).
- Installation of pavers on pedestals possible for technical terrace.
- Gutters (zinc, aluminum), downspouts, flashing, valleys, water outlets: key elements to prevent leaks.
- Reinforcement of supports and junctions with roof frames (flashing, connections).
- Inspection of rafters/joists, replacement or reinforcement if necessary, preventive treatment for moisture.
- Preparation for sarking (external insulation) during a complete refurbishment.
- Under-roof screen + ventilation = healthy base for future insulation.
- Advice on shading for roof frames, air circulation, and protection against overheating.

Common issues in Namur: our solutions
Recurring leaks around chimneys and valleys
We replace the flashing (lead/zinc), redo the valleys, check the screen and the fixings. Result: no more stains on the ceiling, healthy support.
Tiles/slates lifting in the wind
Poor fixing or aging. We replace the elements, review the hooks/nails, install the screen and ensure regulatory ventilation.
Bubbling flat roof
Old waterproofing, insufficient slope. We switch to a warm roof with slopes ≥ 2 %, compliant rises and adjusted drainage.
Overheating in the attic
We guarantee under-roof ventilation, plan for external shading on roof frames and prepare the insulation (future or immediate project).
FAQ - Roof renovation
Do I always need to replace the entire roof?
No. A partial renovation may be sufficient (valleys, flashings, exposed rows). If multiple issues coexist (roof nearing end of life + waterproofing + tired framework), a complete renovation is more sustainable.
Is an under-roof screen really necessary?
Yes, it protects against dust and water driven by the wind, while allowing steam to pass through (breathable membrane). It improves durability and prepares for effective insulation.
Can I stay in the house during the renovation?
In most cases, yes. We phase by slopes, protect the attic and inform in advance of the noisier moments (removal, valleys).
Tiles, slates or zinc: what to choose?
It all depends on the style, budget, slope and environment (winds, frost). Slates offer a sober and durable finish, tiles provide a wide range of shades, and zinc excels in low slope and modernity. We compare on-site.
How long does a construction site last?
Standard house 100–150 m²: 1 to 3 weeks depending on material, access and weather (excluding supply delays). With dormers/complexities, plan for more. A phased schedule is provided.
Urban planning, Energy performance and co-ownership
- Urban planning: replacement in kind = generally without permit; change of appearance (material/color, dormer, elevation) may require declaration or permit. We help compile the file (photos, sheets, colors).
- Energy performance & renovation process: a renovated roof with screen and ventilation is ready for insulation (interior or sarking). We document the implementation (sheets, photos) for good energy performance recognition.
- Co-ownership: facade/roof = often common areas. File syndic/AG (safety, nuisances, aesthetics), protections and logistics (elevator, schedules).
