A roof edge closure or an attic cover sheet usually consists of sheets that are folded several times. They complete the sealing of the parapet at the edges of the roof.
More about parapet cover plates / roof edge closure
If there is no gutter, an edge finish is required on the roof edges of roof waterproofing. In principle, a distinction can be made between two variants of parapet cover plates or roof edge closures:
- roof edge end profile (one-, two- and multi-part), consisting of holder, panel and support plate.
- Roof edge covering, which is made of multi-folded sheet metal and includes the parapet.
The profiles for the roof edge closure usually consist of a holder, support plate and panel. They are usually made of sheet metal that is folded several times. In the case of the parapet of flat roofs, the slope must slope towards the roof and should be 2 to 3°
.
The
most important regulations in accordance with the Flat Roof Directive (point 4.6) and the technical rules for metalwork in the roofing trade:
- The height of roof edgeclosures should be approx. 10 cm for roof pitches up to 5°, and approx. 5 cm above the upper edge of the pavement or gravel fill for roof pitches above 5°. Roof edge closures must be inclined to the roof side so that rainwater can drain inwards.
- The outer leg of covers or edge profiles should overlap the upper edge of plaster or cladding, depending on the height of the building, i.e. up to 8 m > 5 cm. About 8-20m ->8cm. About 20m -> 10cm.
- The protrusion of covers or edge profiles must have a drip edge of at least 2 cm distance from the building parts to be protected.
- Roof edge end profiles and roof edge covers, including their parts and fastenings, must withstand the expected stresses from wind loads. The occurring loads and their calculations are regulated in DIN 1055: Effects on Structures, Sheet 4 .
- Roof edge covers should also have a clear slope to the roof side so that rainwater can drain off with the impurities deposited on the top of the panel.
