Many standard terrace roofs are fixed in size and shape, often failing to match the building's architecture and lacking well-integrated lighting, shading, or drainage. The SUNFLEX aluminum terrace roof, on the other hand, is custom-made to measure and, thanks to four system variants and numerous roof types, allows for precise adaptation to the floor plan, snow load, and desired aesthetic. Integrated cable routing for LED lighting, the option of surface-mounted or integrated shading, and optional heating systems make the aluminum terrace roof usable year-round. High-quality aluminum profiles, connectors for easy assembly, and the option of concealed screws (e.g., SF300 aluminum terrace roof) ensure durability, an elegant design, and reduced maintenance. DIN EN 1090 certification (SF112, SF152) and the possibility of project-specific structural calculations ensure that the terrace roofs meet all building code requirements.

SF112 vs. SF152 (terrace roofs with external statics):

Both terrace roof systems utilize external structural support and allow for forward roof overhangs. The SF152 terrace roof, with its 152 mm rafter height, has a more robust construction than the SF112 (112 mm), thus permitting larger spans and higher snow loads. The SF152 achieves maximum roof depths of up to 6,600 mm, while the SF112 is limited to 4,800 mm. The SF152 is suitable for more demanding structural requirements, while the SF112 is ideal for any standard project.

SF125 (terrace roof with internal statics):

The SF125 aluminum terrace roof features internal structural support, making the rafters less visible and creating a minimalist look. Roof overhangs are not possible, but the SF125 offers the largest span of all SUNFLEX terrace roofs, with a roof depth of up to 6,600 mm. The roof width reaches an impressive 15,000 mm. Perfect for spacious terraces with a clean, uncluttered soffit.

SF300 (cubic terrace roof):

The F300 is a premium cubic terrace roof with a minimal 2° pitch and surrounding cladding (300 mm high). Like all SUNFLEX terrace roofs, the F300 also features high-quality profile covers without visible screws. However, with the F300 terrace roof, the rain gutter and the entire structural framework are also concealed behind the elegant all-around cladding. The integrated LED lighting and the modern, angular design complement contemporary, minimalist architecture. The F300 achieves a roof width of up to 15,000 mm and a roof depth of up to 4,500 mm – perfect for high-quality residential and commercial buildings with flat roofs.

Decision-making aid for your terrace roof:

• Terrace roof SF112: Standard solution, versatile application, roof overhang possible
• Terrace roof SF125: Internal structural support, large spans, clean look
• Terrace roof SF152: External structural support, higher load-bearing capacity, sophisticated structural design
• Terrace roof SF300: Cubic design, surrounding cladding, modern architecture

All SUNFLEX terrace roofs are manufactured according to individual specifications. The project-specific structural calculations for the terrace roof are carried out by a SUNFLEX specialist partner or a structural engineer authorized to submit building plans. Snow load, wind load, glass construction, and connection structure are all tailored to the specific building project. Homeowners can rely on a terrace roof that complies with building regulations and enjoy complete planning security.

Dimensions: The aluminum terrace roof is individually customized in width, depth, eaves height, and ridge height. Please note the minimum and maximum dimensions for the terrace roof.

• Roof pitch: Terrace roofs SF112, SF125, and SF152 allow pitches from 3° to 45°. The terrace roof SF300 operates with a minimum pitch of 2° for controlled water drainage.
• Glass construction: Glass thicknesses of 8 mm, 10 mm, or 12 mm are available, depending on the span, snow load, and thermal insulation requirements.
• Roof types: Nine different roof types (shed roof, hip roof, freestanding, corner constructions, and more) allow for flexible floor plan adaptation.
• Shading: Optional shading systems can be integrated, either above or below the roof.
• Lighting: Integrated cable channels for LED spotlights are available in all aluminum terrace roof systems; continuous lighting is possible with the SF300. 

The installation of the terrace roof is carried out by qualified SUNFLEX partners who handle measurements, consultation, structural calculations, and professional installation. If you use the SUNFLEX terrace roof configurator, you can select a partner near you in the final step of the configuration process.

The choice of system for your terrace roof depends on the architecture, desired look, structural requirements, and roof shape. The SF112 aluminum terrace roof is a versatile standard solution suitable for most terrace roofs. The SF125 offers internal structural support for a minimalist look and larger spans. The SF152 terrace roof is the right choice for higher snow loads or larger spans. The SF300 terrace roof complements modern, minimalist architecture with a cubic design. Your SUNFLEX specialist partner will advise you on the optimal terrace roof solution.

Yes, the SUNFLEX terrace roof can be perfectly combined with SUNFLEX sliding window systems (SF40, SF60, SF80) or sliding-folding systems (SF30). The sliding window systems feature a practical follower mechanism, so that multiple panels move automatically when opened – for particularly convenient operation. Sliding-folding systems allow you to open the side glazing almost completely, as the panels can be rotated outwards and slid to the side. You can also choose between different insulation levels, allowing you to create either an airy summer garden or a fully insulated conservatory.

The SUNFLEX terrace roof can be fitted with laminated safety glass (VSG), tempered safety glass (ESG), or insulated glass. Glass thicknesses of 8 mm, 10 mm, and 12 mm are available. The specific glass choice for your terrace roof depends on the span, snow load, thermal insulation requirements, and safety requirements. Your specialist partner will determine the appropriate glass construction for your aluminum terrace roof.

All SUNFLEX terrace roofs have integrated cable channels for installing LED spotlights. This lighting provides pleasant illumination in the evenings and allows for year-round use of the terrace. The SF300 terrace roof also features continuous LED spotlights on the front, right, and left sides for even lighting. The lighting can be controlled via standard switches or smart home systems.

Yes, the SUNFLEX aluminum terrace roof can be equipped with either top-mounted or integrated shading systems. Shading for the aluminum terrace roof protects against direct sunlight in the summer, prevents overheating, and provides pleasant shade. Ideally, the shading system is integrated into the terrace roof during initial installation, but it can also be retrofitted by qualified professionals.

SUNFLEX offers nine different roof types for its aluminum terrace covers: shed roofs, hipped roofs, freestanding terrace covers, corner roofs, terrace covers with side connections, terrace covers without front connections, and other variations. The choice depends on the floor plan, connection situation, architectural design, and personal taste. You can explore the individual options in the terrace cover configurator.

The SUNFLEX terrace roof features integrated gutters and downpipes. For the SF112 and SF152 terrace roofs, you can choose between square or round gutters, while on the SF300 terrace roof, the gutter is concealed behind the surrounding fascia. Water from the terrace roof drains via downpipes with optional downpipe trims. The roof pitch ensures reliable drainage, even during heavy rain.

Snow load calculations are project-specific and depend on location, snow load zone, span, and glass construction. DIN EN 1090 certification (terrace roof SF112, SF152) and individual structural analyses ensure the required load-bearing capacity of the terrace roof. Regions with high snow loads require stronger profiles, thicker glass, or closer rafter spacing. SUNFLEX terrace roofs offer a particularly high snow load capacity of up to 350 kg and are therefore among the safest terrace roofs in terms of snow load.

Yes, the aluminum profiles and glass surfaces of the terrace roofs are weather-resistant and require only occasional cleaning. The gutters should be cleared of leaves and debris annually. The shading mechanism and LED lighting are also designed for low maintenance. A visual inspection of the terrace roof by a specialist every 2–3 years is recommended.
