Your tiled roof guide
Practical explanations for choosing, renovating and maintaining a tiled roof. Explore 24 topics before preparing your own plan.
Replacing roof tiles: inspection to handover
A new tiled roof starts with a clear assessment of the old one. Compare repair, reuse and replacement before selecting a model.
Types of roof tiles
Clay and concrete tiles come in flat, profiled and traditional families. Shape and colour influence appearance, while technical suitability determines where a model can be used.
Colours and finishes
Natural red, grey, anthracite and other tile colours change with daylight, surface finish and the surrounding facade.
Ridge and hip tiles
Ridge tiles close the meeting point of roof slopes; hip tiles follow sloping external corners. Both belong to the roof system.
Lead and lead substitutes
Flashings protect junctions with chimneys, walls and other roof elements. Their detailing is as important as the material.
Choosing roof windows
Choose a roof window for daylight, room use, reachable controls and the view. Consider shading and cleaning access too.
Roof insulation choices
The right insulation depends on existing layers, the use of the loft and whether the covering is being renewed.
Insulating a roof from inside
Internal insulation may suit a roof whose covering remains in place. The existing layers must first be understood.
External and sarking insulation
External insulation can provide a continuous layer when the roof covering is renewed. It also changes the height of the roof build-up.
Understanding Rd, Rc and lambda
Rd describes thermal resistance of a material layer; Rc concerns the construction. Lambda describes a material’s thermal conductivity.
Solar panels on tiled roofs
Assess the roof before installing panels. Later roof repairs can require the solar installation to be removed again.
Improving the sustainability of a roof
Start with condition and necessary repairs, then coordinate insulation, roof windows and solar panels.
Warranties, certificates and your roof file
Keep product warranty, system warranty and workmanship warranty separate. A brand name or certificate does not cover every aspect of the roof automatically.
How long do roof components last?
There is no single guaranteed lifespan for every tile or roof component. Materials, exposure, detailing and maintenance all influence condition.
Maintaining a tiled roof
Regular checks can reveal slipped tiles, blocked drainage and deteriorating junctions before the damage grows.
Investigating roof leaks
The visible damp patch may be some distance from where water entered. Rain, wind and condensation can produce different patterns.
Every part of a tiled roof
A tiled roof is a coordinated set of layers and details, from the structure to the visible covering.
Roof shapes and their details
Gable, hipped, mansard, mono-pitch and combined roofs have different junctions and tile layouts.
Roof pitch, overlap and batten spacing
A roof tile must suit the actual pitch and the required weather protection. There is no universal minimum pitch for every model.
Roof tile replacement costs from €75 per m²
Concrete roof tile replacement from €75 per m² and clay roof tiles from €95 per m², including VAT. See the basic work, example budgets and costs that depend on your roof.
Preparing for insulation subsidies
Subsidy eligibility depends on the applicant, work and current scheme conditions. Check the official Dutch RVO information before committing to an assumption.
Recognising and reusing old roof tiles
Reuse depends on condition, dimensions, interlock and the number of usable pieces. A familiar shape is not proof of an exact match.
Underlay, vapour control and ventilation
Roof underlay, internal vapour control and ventilation have different functions. They must be selected together for the full build-up.
Gutters, valleys and rainwater drainage
Rainwater needs a continuous route from the roof covering to gutters, outlets and downpipes. Valleys collect water from adjoining slopes.
