Wooden Roofing for Restaurants and Terraces: Types, Installation and Maintenance [2025 Guide]
Wooden roofing in restaurants not only serves a structural and protective function; they are architectural elements that define the space's identity and contribute significantly to the dining experience.
Types of Wooden Roofing for Gastronomic Spaces
1. Wooden Pergolas

- Open structure with parallel beams
- Allows partial light passage
- Ideal for terraces and patios
- Natural shade without enclosure
Recommended materials:
- Teak: Superior weather resistance
- Ipe: Exceptional hardness, minimal maintenance
- Red cedar: Natural aroma, repels insects
- Tzalam: Mexican option, excellent cost-benefit ratio
Typical dimensions:
- Main beams: 15×20cm or 20×20cm
- Rafters: 7.5×15cm @ 60cm
- Heights: 2.80-3.50m
2. Interior Wooden Ceilings
Applications:
- Interior dining rooms
- Bar areas
- Private dining rooms
- Climate-controlled spaces
Installation types:
- Tongue and groove: Boards with male-female assembly
- Separated planks: Contemporary effect
- Acoustic panels: Reverberation control
Recommended woods:
- Pine: Economical, accepts stains well
- Oak: Marked grain, elegant
- Maple: Light tones, modern
- Walnut: Maximum luxury
Functional advantages:
- Acoustic absorption (reduces echo and noise)
- Superior thermal insulation
- Conceals installations (HVAC, electrical)
- Warm and welcoming aesthetics
3. Gable Roofs with Exposed Structure
Characteristics:
- Visible beams and rafters
- Variable heights
- Covering over structure
- Rustic-modern style
Structural elements:
- GLT main beams: 240×600mm typical
- Timber rafters: 7.5×20cm @ 80cm
- Covering: Tile, sheet metal, or shingle
Advantages:
- Double-height spaces
- Superior natural ventilation
- Possible zenith lighting
- Great visual impact
Ideal applications:
- Country restaurants
- Breweries
- Grills
- Semi-covered terraces
4. Integrated Deck and Roof for Terraces
Complete system:
- Wooden deck (floor)
- Roof structure
- Protective covering
- Integrated lighting
Woods for deck:
- Ipe: Best option, 25+ years durability
- Teak: Excellent, ages gracefully
- Cumaru: Economic alternative to ipe
Integrated design:
- Roof beams anchored to deck structure
- Coordinated installation passages
- Integrated rainwater drainage
5. Contemporary Palapa
Evolution of traditional palapa:
- Robust wooden structure
- Treated palm covering
- Combination with modern elements
Advantages:
- Exceptional thermal insulation
- Tropical/beach aesthetics
- Competitive costs
- Unique atmosphere
Applications:
- Beach restaurants
- Urban tropical terraces
- Beach clubs
- Themed spaces
Technical Installation Considerations
Structural Design
Loads to consider:
- Self-weight of structure
- Covering and finishes
- Maintenance live load: 100 kg/m²
- Wind load according to zone
- Rain load (accumulation)
Common spans in restaurants:
- Interior tables: 4-6m between supports
- Terraces: 6-8m
- Open areas: up to 12m with GLT
Weather Protection
Exterior finishes:
- Exterior wood oil (reapplication every 1-2 years)
- Marine varnish (greater durability, less natural)
- UV filter stains
- Waterproofing sealers
Preventive treatments:
- Insect protection impregnation
- Anti-fungal treatment
- Fire retardants (indoors near kitchens)
Protective design:
- Adequate overhangs (min 60cm)
- Minimum 15% slopes for drainage
- Wall separation for ventilation
- Avoid water accumulation
Installation Integration
Lighting:
- LED recessed in beams
- Pendants integrated in structure
- Hidden perimeter lighting
- Directional spots
Fans:
- Reinforced anchoring in main beams
- Electrical boxes integrated in structure
- Hidden cable in wooden channels
Audio:
- Recessed speakers
- Hidden wiring
- Acoustic treatment if necessary
HVAC:
- Integrated diffusers (if applicable)
- Coordinated air return
- Additional thermal insulation
Maintenance by Roof Type
Exterior Pergolas
Annual maintenance:
- Deep cleaning (low pressure water)
- Crack and fissure inspection
- Surface sanding of worn areas
- Protective oil reapplication
- Anchor and hardware verification
Signs requiring attention:
- Gray color (unprotected wood)
- Cracks larger than 3mm
- Areas with fungus presence
- Rusted screws
Interior Ceilings
Minimal maintenance:
- Cleaning every 6 months (dry cloth)
- Moisture stain review
- Loose panel verification
Common problems:
- Grease stains (near kitchens)
- Moisture from roof leaks
- Discoloration from direct sunlight
Roofs with Covering
Biannual inspection:
- Covering condition (tiles, sheet metal)
- Gutter and downspout cleaning
- Seal verification
- Visible structure condition
Structure maintenance:
- Every 2-3 years: Finish reapplication
- Annual: Connection review
Commercial Advantages for Restaurants
Average Ticket Increase
Market studies indicate:
- Terraces with natural ambiance: +15-25% in ticket
- Customers stay 20-30% longer
- Higher probability of additional consumption
Organic Marketing
Instagram and social media:
- "Instagrammable" spaces generate content
- Well-designed wooden roofs are highly shareable
- Invaluable organic marketing
In saturated markets:
- Wooden roof immediately distinguishes
- Association with quality and naturalness
- Justifies premium pricing
Regulations and Permits
Municipal Requirements
Typical required documentation:
- Structural project signed by structural engineer
- Calculation report
- Architectural and structural plans
- Construction permit application
Special considerations for terraces:
- Height restrictions
- Allowed roofed area percentage
- Transparency requirements (pergolas)
Fire Protection
Restaurants must comply:
- Fire retardant treatment in interior structures
- Integrated smoke detectors
- Accessible fire extinguishers
- Emergency signage
Treated wood can achieve:
- Retardant classification (Class B)
- R-30 or superior resistance time
