Rain Gutter Installation Assembly instructions


Before you start

It is the total area of the roof that decides the dimensions of the roof drainage system. The bigger the roof, the more water the system must take care of. It will pay in the long run to be careful when you measure your roof and calculate dimensions. Take your calculation to your local dealer, who will help you to pick out all the components you need. Please, also visit our web site www.lindab.se/xxxxx for dimensioning help.

Measure the roof area

There are various types of roofs but measure each roof part by multiplying the roof length with the roof width. If the area is less than 50 m² use gutters with 100 mm width and pipes with 75 mm diameter. If the area is between 50-100 m² use gutters with 125 mm width and pipes with 87 mm diameter. If the area is larger than 100 m² there are gutters with 150 mm width and pipes with 100 mm diameter or 190 mm gutters and 111/120 mm pipes. If there are different roof sizes on the same building the largest roof part is dimensional.

Number of brackets and drain pipes

The brackets should be mounted with c/c 600 mm. The end brackets are mounted 100 mm from the roof edge. The inclination of the gutter towards the down pipe should be at least 2,5 mm/m. Calculate how many brackets you need for each roof part (example 10 m/0,6 m +1 = 18 brackets). Each drain pipe covers maximum 10 m gutter fall (length of the house). For a estethic reasons or if the gutter fall exceeds 10 m, place pipes on each corner of the house.


Where to place the pipes

The pictures below show recomended placement of drainpipes for different houses.


Transport, storage, unpacking

Make sure that the roof drainage components are handled with care during transport, storage and unpacking. If not, the coating may be damaged or the pipes and gutters dented. Store pipes and gutters on a plane and stable surface. Non coated components must be unpacked and stored in a dry and ventilated place.

Cutting

Cut the gutters and pipes with plate shears or a hacksaw on a firm underlay on the ground. Never use an angle grinder. It heats the steel up up and thus destroyes the galvanization. The coating may also be scorched by hot chips or filings.

After-treatment

If the coating has been damaged, paint it with Lindab's repair paint to prolong the lifespan of the roof drainage system. Use a sponge or Lindab's paint nib.

Maintenance

If you want to keep the roof drainage system in mint condition, give the system an overhaul a couple of times a year. Clean the gutter and pipes from leaves and twigs. Wash with water and a mild detergent. Don't use a high pressure washing appliance.


Tools

Lindab's roof drainage system can be mounted with ordinary hand tools like pliers, hammer, hacksaw, screwdriver, folding rule and string. For bending brackets, you need a bracket bender. Contact your local dealer and they will lend you one.

Fastening

The fasteners you need are for fastening the brackets and the pipe holders. We always recommend that you use stainless screws and use the right screws intended for each material. The pipe holders are mounted on the house façade. Check if it´s wood, concrete or bricks.
