Nationwide Roofing Southern installs and repairs flat roofs across Sussex for homes, extensions, garages, commercial buildings, podiums and other low-slope structures. We specify the waterproofing system around the roof’s use, substrate, falls, outlets, upstands and expected foot traffic.
Options include built-up felt, single-ply membranes, asphalt, lead and hot melt roofing. The right choice depends on the building and detail requirements, not simply the appearance of the finished surface.

Flat roofing can suit extensions, garages, commercial buildings, terraces, podiums and green-roof bases because it makes efficient use of a low-slope structure. Performance depends on the complete build-up, including the deck, vapour-control layer, insulation, waterproofing, falls, outlets and perimeter details.
Different systems solve different problems. Built-up felt provides a layered waterproof finish, single-ply membranes can cover large roof areas with relatively few seams, and hot melt forms a fully bonded seamless membrane around complex details. Lead and asphalt may suit particular architectural or heritage requirements.
Drainage and detailing are central to reliability. Correct falls move water towards outlets, while carefully formed upstands, penetrations and edge details protect the vulnerable parts of the roof. Our guide to common flat roof problems in Sussex explains why these areas deserve attention.
A flat roof installation begins with the structure and intended use of the roof:
Routine checks help identify blocked outlets, surface damage and deteriorating details before they become larger defects. See our flat roof maintenance guide.

Single-ply membranes such as EPDM are a modern solution for flat roofs, offering excellent thermal insulation and energy efficiency. Lightweight and flexible, single-ply membranes are easy to install and perfect for environmentally-conscious homeowners. This type of roofing is highly resistant to harsh weather conditions and UV rays, ensuring long-term durability.
With single-ply roofing, you benefit from both aesthetic appeal and eco-friendly performance for your property.
Lead roofing is the ideal choice for heritage and period properties, providing both longevity and a traditional aesthetic. Lead is highly durable, resistant to extreme weather conditions, and can last over 100 years when properly installed. It’s also incredibly malleable, making it perfect for complex roof designs and decorative elements on older buildings.
If maintaining the heritage look of your property is essential, lead roofing offers a timeless, dependable solution.
Asphalt roofing is a highly durable and cost-effective solution for flat roofs. Known for its waterproofing capabilities, asphalt roofs are ideal for both residential and commercial properties. With its excellent resistance to weathering, UV rays, and heavy rain, asphalt roofing provides long-lasting protection.
Asphalt roofing is also low-maintenance and can be easily repaired if necessary, making it a reliable option for property owners looking for an efficient, long-lasting flat roof solution. It’s a great choice for those who want affordable durability without compromising on performance.
If your flat roof is leaking or showing signs of wear, Nationwide Roofing Southern provides fast, reliable repairs to restore its functionality.

Regular maintenance can extend the life of your roof, preventing costly issues down the line. Whether it’s routine upkeep or urgent repairs, our experienced team ensures your roof stays in top condition for years to come.
Hot melt roofing is a fully bonded waterproofing system used on flat roofs, podium decks, terraces and green-roof bases. The membrane is applied hot in reinforced layers, allowing it to follow complex shapes and form continuous waterproofing around upstands, outlets and penetrations.
Hot melt is particularly relevant where the roof has intricate detailing or will support another finish above the waterproofing. The substrate, falls, drainage, protection layers and overlying build-up must all be considered as part of the specification.
