SERVICES

  • Quality roof sheeting forms the foundation of any reliable roofing system. JNA Group's roofing contractors expertly install IBR sheeting solutions that provide exceptional weather resistance and structural integrity. Our team combines four decades of experience with precision installation techniques, ensuring your sheeting performs optimally across South Africa's diverse climate conditions. Whether residential or commercial applications, we source premium materials that complement both timber roof structures and conventional framing systems.

  • Natural slate roof coverings represent the pinnacle of roofing elegance and longevity. Our craftsmen understand the intricate requirements of slate installation, from proper underlayment systems to precise fastening techniques. Each slate roof project reflects our commitment to preserving architectural heritage while delivering modern weatherproofing performance. The natural beauty of slate harmonises beautifully with timber facades and wooden roof structures, creating sophisticated building envelopes that enhance property value.

  • Owen Corning Duration shingles offer exceptional durability and aesthetic versatility for residential roofing projects. These engineered shingles provide superior wind resistance and extended warranties, making them ideal for South African weather conditions. JNA Group's installation expertise ensures proper ventilation integration and flashing details that protect underlying timber roof systems. Our shingles installations complement various architectural styles while maintaining the craftsmanship standards established over our 40-year heritage.

  • Premium zinc roofing materials deliver unmatched longevity and distinctive architectural character. RHEINZINK systems develop natural patina over time, creating weather-resistant surfaces that require minimal maintenance. Our specialised installation techniques ensure proper thermal movement accommodation and weather-tight sealing. These sophisticated metal roofing solutions integrate seamlessly with engineered timber roofing structures and custom roof trusses, providing both functional performance and striking visual appeal for discerning clients.

  • VELUX roof windows transform attic spaces into functional living areas while maintaining structural integrity. Professional installation requires precise flashing integration and proper insulation detailing around timber framing members. Our roof window specialists ensure optimal positioning for natural lighting while preserving energy efficiency. These installations frequently complement loft conversions and timber house construction projects, adding value and livability to previously underutilised spaces beneath timber trusses.

  • Loft conversions maximise property potential while preserving existing architectural character. JNA Group's approach integrates structural timber engineering with practical space planning, often incorporating exposed trusses as distinctive design features. Our conversions frequently include VELUX roof windows and specialised insulation systems that work harmoniously with timber ceilings and T&G ceiling finishes. Each project respects the existing wooden roof structures while creating contemporary living spaces that reflect both heritage and innovation.
