Green Roof construction

Topseal Green Top

Topseal green top is a complete green roofing system with an option to use either wild flowers or sedum.

Commonly found in Europe, green roofs have started attracting homeowners and businesses to promote environmentalism while getting their roofs a much needed makeover. Green roofs mimic traditional vegetation without disrupting or affecting the natural urban infrastructure. It makes use of neglected and unused space and transforms it into functional roofs.

Green roofs usually reduce energy cost with its natural insulation. It also creates a sanctuary for people and animals. It also absorbs rainwater, cutting the need for expensive and complex drainage systems. Moreover, this type of roofing improve air quality and help reduce urban heat island effect—a condition where a city absorbs and traps heat. Anybody who has walked across a stifling parking lot one hot, summer day has probably felt the effect of being inside an urban heat island.

A green roof’s layer, like any other roof, must accommodate drainage and protect a structure from the sun’s heat and rain through a waterproof membrane. However, the layers of a green roof must constantly provide space for the plants to grow. A green roof should be able to support the plants without compromising the structural integrity of the entire structure.

Truly, green roofs are starting to become a hit as an environmentally-friendly roofing alternative. So what are the steps required to produce a topseal green top roof ?

From the top you would have your sedum layer, ontop of green top substrate ,ontop of a drainage/water retension layer, this is layed ontop of  one layer of topseal top coat, laid ontop of 2 x 450 g/m2 reinforcement mat, laid ontop of 18mm OSB

Topcoating the roof

Topcoating the roof
Preparation for Topcoating the roof

top coating fibreglass roof

Fibreglass Roofing Scotland Take particular care and attention at this stage will produce a roof of superb appearance. Using a sanding pad with a 40 grit sand paper, lightly sand the corners and trim bandages. Sand off any unsightly fibres, taking care not to sand too heavily on the corner . Cut any excess cured mat protruding beyond the trim with a sharp Stanley knife.

Fibreglass Roofing ScotlandSeal any edges with abutting walls using a clear silicone sealant. Fit any C100 simulated lead flashing before top coating and seal off with a clear silicone sealant.

Topcoating the roof

The Topcoat is a resin and should be treated in the same way as the base resin. It requires the addition of catalyst for it to cure.

Fibreglass Roofing ScotlandAlways try to apply the topcoat immediately after the laminate is semi-cured If this is not possible then ensure topcoating is carried out within 24 hours to gain a good bond with the laminate. If the topcoating is left longer than 24 hours then wash down the laminate with acetone to gain a good cross-polymerisation of the topcoat to the laminate.
Mixing the topcoat

Cured topcoat is needed rather than the standard pre-pigmented grey, a colour pigment will need to be added to a clear topcoat. A 20 kg tin of topcoat requires 2kg of colour pigment. there are a variety of different colours available

Applying the topcoat

Fibreglass Roofing Scotland Use a 7” polyester roller, cover the remaining laminate with just enough topcoat for the fibre pattern to be visible.

We use a 2½” Polyester roller to coat the trims. A roller will get a better and more even finish than a paintbrush. Roll the topcoat along the face of the trim. Fibreglass Roofing Scotland protect the fascia from topcoat, hold a piece of flashing trim against it as you topcoat the radius on the underside of the trim.
