chapterGreen roof

A green roof is both beautiful and useful. It significantly regulates the temperature inside the building.

According to a report published by Canada's National Research Council, a green roof can reduce the need for air conditioning by up to 75%. Green roof layers protect the waterproofing from major temperature changes and mechanical damage.

Plants capture dust and airborne pollutants and help absorb noise. A green roof retains 70–90% of rainfall in summer and about 40% in winter. Areas of varied vegetation provide habitats for microorganisms, invertebrates, small insects and birds.

A green roof can also be an advantage when selling a house or apartments, or letting residential and commercial premises.

chapterRoof types

Two ways to use the roof

EXTENSIVE GREEN ROOF

  • A major advantage of an extensive green roof is its low maintenance requirement.
  • Once established, the plants do not require regular irrigation, mowing, pruning or fertilising.
  • The roof is planted with species that tolerate extreme conditions, including alternating heat, drought and frost.
  • Sedum is the most commonly used planting. These plants gradually spread across the surface to form a dense carpet.
  • The most commonly used extensive green roof build-up has an 8–10 cm substrate layer. Fully saturated with water, it loads the roof by up to 100 kg/m².

INTENSIVE GREEN ROOF

  • This is the best choice if you plan to spend time on the roof. It supports a wide variety of species. The depth of substrate determines which types of plants can be grown.
  • Lawn is the most common roof covering for this type.
  • This option requires at least 20 cm of substrate. Pre-grown turf is laid on top, and you can enjoy the garden once installation is complete.
  • Regular maintenance is important: mowing, fertilising and irrigation. For an intensive green roof, allow for a total build-up weight of approximately 300 kg/m².
chapterECOSEDUM®

ECOSEDUM® GREEN ROOF

ECOSEDUM® is a patented tray that stores the required amount of rainwater and releases it to the roots during hot weather.

The ECOSEDUM® PACK green roof system creates a near-natural vegetation layer that maintains and renews itself. We supply the roof trays with pre-grown, perennial, frost-resistant and adaptable plants.

They can withstand even extreme weather conditions.

ALLOWS ROOF ALTERATIONS AND REPAIRS

Our modular green roof system offers exceptional flexibility.

If the roof covering beneath the green roof needs repair, simply remove the modules temporarily in that area, repair the covering and return the modules to their original positions.

The green roof is immediately complete and uniform again.

ROOF GARDEN

  • The most interesting, but also most demanding, form of intensive green roof is a roof garden. It can include small trees, shrubs and ornamental flowers.
  • A roof garden can also be used to grow fruit and vegetables.
  • It is an excellent place to relax and recharge, especially in busy cities.
  • A natural environment benefits both physical and mental wellbeing.
chapterScope of work

WALKABLE ROOF

Would you like a roof terrace? In practice, this is a walkable roof. It is popular with builders and designers, although poor experiences in the past still make some people wary of flat roofs. These challenges can be addressed.

As with any roof, a walkable roof needs watertightness, insulation, strength and functionality. Modern materials help GAMAT achieve these properties in both new roofs and renovation of old or damaged roofs.

These include APP-, SBS- and APAO-modified bitumen membranes and waterproofing membranes with high mechanical resistance and excellent elasticity. They resist overstressing, tearing, puncture and movement.

The innovative materials we use for flat roof waterproofing are durable and provide reliable support for roofs exposed to pressure and substantial mechanical loads every day.
