Installation de toit métallique: étapes de base

Flat metal sheets can be ordered in lengths ranging from 0.84 m to 5.74 m in any dimension, while the modular sheets include multiples of 0.35 m (one module) increase by 0.14 m. For example: 12 waves x 0.35 = 4.20+0.14= 4.34 m. In the case that rafters are larger than 5.75 m the sheets are bonded together and the length requested by the client i.e. 7.58 m is distributed evenly provided that the bottom sheet is the sheet from the modular i.e. 3.64 while the upper remnants are divided amongst rafters adding 14 cm on the tab – 4.08. It is also possible to divide the sheets in the place specified by the recipient.

Not to be used in one piece of sheet larger than 5.75 m due to the expansion of the material under the influence of temperature, and the possibility of damage during transporting, mounting and handling.

If you need to store metal flat sheets for a long period of time it is necessary to:

  • get completely rid of the protective film
  • store the material in a dry and ventilated place, without the presence of neighboring aggressively responsive materials
  • separate the material from the ground a minimum of 20 cm
  • transfer each individual sheet divider

When moving long sheets the number of people should be chosen carefully to prevent any danger.

Sheets absolutely should not be placed directly on the paper, but rather on permeable film using battens and counter battens. This structure of patches and battens can also be used on boarded roofs covered with tar paper. It provides proper ventilation, slope, and prevents condensation of water vapor at temperature jumps. With a small decrease in slope, the lower parts of the roof are good for thickening battens, to reduce the load of snow lying on top. The patches must be nailed exactly parallel to the intervals so that even the plates in its lowest points can be supported. The fixing of the first patch is dependent on the width of the gutters and roof pitch. However, it must be about 16 – 20 mm thicker to compensate for leap knockouts. It can be achieved by using spacers.

The lower edge of the sheet metal roof tiles should go third gutter width. If we use the belt flashings we must remember to mount it in a way allowing the film to the discharge any possible condensation.

The sheets are laid from the left side of roof first attaching “dry” the first three sheets to check the angle, bringing eaves and ridge. Placing each sheet of water groove underneath you should fix them with short screws of about 20 mm ribs on each module.

Carboys are fastened with screws “sheet to sheet;’ in which the second crest of a wave using the previously profiled seals, or universal.

Use snow guards on the roofs of large slopes to avoid spring repair/replacement of gutter system and eliminates the danger of slipping on snow for passersby’s. Experienced contractors have individual solutions accepted by the manufacturer.

It is unacceptable to use the tools in this way because they can cause thermal effects (sudden rise in temperature) at sanders angle. This causes damage to the organic coating and zinc, as a result, beginning the process of corrosion.

Suitable for – the implements are Nibblers. By adding sheets “basket”, remember to leave 4 – 6 cm clearance on the side, which depends on the roof pitch and the basket-type of the trough.

Installation should be organized so that there is as little walk on the attached sheets as possible. When there is such a need to set foot in the “bottom of the wave”, make sure there is no residue left over from the soles after cutting and machining sheet.

In the case of the shell causing minor damage during assembly and processing it’s recommended to prepare varnish (only insite features), available at our store.
