The Roll cap roof system<\/h1>\n[\/vc_column_text][vc_column_text css=”.vc_custom_1634715746333{margin-bottom: 0px !important;}”]The roll cap roof system is suitable for large and small zinc roofs<\/strong><\/a> <\/strong>with a pitch of the roof of at least 3\u00b0, preferably > 7\u00b0, and as fa\u00e7ade cladding. The standard NedZink roll cap roof consists of zinc bays with upstands on both sides and separated by trapezoidal wood rolls. Zinc caps are used to cover these wood rolls. This gives the roll cap its characteristic and robust appearance.<\/p>\n

A roll cap roof is a cladding that consists of zinc sheets equipped with upstands in the longitudinal direction. Between the bays, so-called wood rolls are installed on the timber boarding. These rolls have a trapezoidal cross section with a width of 40-50 mm and a height of 60 mm. The water tight finishing between roof bays and wood rolls is obtained by a covering profile (roll capping).<\/p>\n

Roll cap roofs are installed with clips on the timber boarding. The minimum width of a clip is 50 mm with a minimum sheet thickness of 0.65 mm. Depending on the assembly system, the clip is installed on or under the wood roll. Fixed and sliding clips must also be used with Roll cap roofs. The fixed clips fix the ridge track and the sliding clips allow expansion in the longitudinal direction. For the positioning of the fixed clips, the same rule applies as with a standing seam roof.<\/p>\n

\nThe roll cap system must be fully supported by unplaned, untreated wooden boards at least 23 mm thick, not tongue and grooved, with gaps of at least 5 mm.
\nThe space between the boards can be larger, depending on the pitch of the roof, i.e.
\nroof pitch up to 45\u00ba 5 \u2013 10 mm
\nroof pitch from 45\u00ba – 70\u00ba 5 \u2013 50 mm
\nroof pitch from 70\u00ba – 90\u00ba 5 \u2013 100 mm<\/p>\n

The construction requirements are also important here. Use galvanised nails with a zinc-layer thickness of at least 20 microns or AISI 304 stainless steel for fastening.<\/p>\n
