FAQ
1. Are Roval profiles compatible with different types of roofing?
Yes. Roval roof trims are used in combination with various roofing systems, including synthetic and bituminous roof structures. This makes them flexible for use within a wide range of project specifications.
2. How is the lifespan of Roval aluminum profiles guaranteed?
The combination of aluminum and protective finishes such as anodization or powder coating ensures high resistance to weathering. This results in a long functional lifespan with minimal maintenance interventions.
3. What mounting principles are applied to Roval profiles?
Roval profiles are typically mechanically fastened via screw or screw/plug systems, depending on the substrate. The systems are designed to guarantee a stable anchoring with controlled expansion of the aluminum.
4. Which surfaces are suitable for installation?
Roval systems can be installed on various load-bearing substrates such as:
- Concrete
- Wood structures
- Masonry
- Insulated roof extensions (with correct supporting structure)
The subfloor must offer sufficient load-bearing capacity and flatness for a correct installation.
5. How is watertightness guaranteed at roof edges?
Waterproofing is achieved by a combination of:
- EPDM seals or integrated sealing strips
- Overlaps in profile connections
- Correct positioning relative to the roofing material
- Finishing of corners and joints with system accessories
