These roofing materials can cause problems on the roof edge. This is the result of a number of factors:<\/p>\n<ul>\n<li>Effect of sunlight (heat and U.V. rays)<\/li>\n<li>Differences in expansions between trim, substructure and covering<\/li>\n<li>Bulging of bitumen due to a low softening point<\/li>\n<li>Loosing of the glued edge of the roof trim<\/li>\n<li>Mechanical damage of the roof edge<\/li>\n<\/ul>\n<p>These harmful effects can be avoided by fully covering the edge of the roof with a titanium zinc capping. If NedZink material is used and applied with the necessary craftsmanship, the expected service life is 50 years or longer.<\/p>\n<p><span id=\"aw-open-accordion\"><strong>\u2192 Click here to view the additional information on zinc cappings <\/strong><\/span> <span id=\"aw-close-accordion\"><strong>\u2192 Hide information about zinc cappings<\/strong><\/span><\/p>\n<div id=\"aw-accordion\">\n<h2>Construction details for the zinc capping<\/h2>\n<p>The zinc capping is designed according to the example figures 7.1.1, 7.1.2 and 7.1.3. The upper surface of the zinc capping must slope down in the direction of<br \/>\nthe roof or must be provided with a rain ridge, see figure 7.1.3.<\/p>\n<p>A number of important construction details;<\/p>\n<ul>\n<li>The upper surface of the zinc capping must slope down in the direction of the roof or must be provided with a rain ridge, see figure 7.1.3.<\/li>\n<li>The zinc capping is attached by means of zinc clips of a width of at least 80 mm that are fastened to the edge of the roof with at least 2 screws or zinc nails. The distance between the clips amounts to a maximum of 1 meter.<\/li>\n<li>The material for the clips must be at least 0.80 mm thick.<\/li>\n<li>The use of stainless steel or galvanised steel clips is recommended for zinc cappings with a long sloping part of &gt; 150 mm. The same goes for zinc cappings with a developed width as from 450\/500 mm, by which the zinc capping can be regarded as a roof bay. The number of clips must be adapted to this.<\/li>\n<li>The zinc cappings must be soldered to one another up to a maximum of 12 meters length with an overlap of at least 15 mm. After every 12 meters an expansion sleeve must be fitted at one\u2019s option, see figure 7.1.4.<\/li>\n<li>The underlying roof covering must be glued over the entire width of the roof edge.<\/li>\n<\/ul>\n<p>See also:<\/p>\n<p><a href=\"https:\/\/www.nedzink.com\/en\/building-features-2\/dormers\/\"><strong>Dormers<\/strong><\/a><br \/>\n<a href=\"https:\/\/www.nedzink.com\/en\/building-features-2\/wall-copings\/\"><strong>Wall copings<\/strong><\/a><\/p>\n<\/div>\n[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][mk_padding_divider size=&#8221;20&#8243;][vc_single_image image=&#8221;34529&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221;][\/vc_column][vc_column][vc_single_image image=&#8221;34539&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221;][\/vc_column][\/vc_row][vc_row][vc_column][mk_padding_divider][\/vc_column][\/vc_row][vc_row el_class=&#8221;rij-wit-schaduw&#8221;][vc_column][mk_padding_divider][vc_single_image image=&#8221;34549&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221;][mk_padding_divider size=&#8221;20&#8243;][mk_padding_divider size=&#8221;20&#8243;][vc_single_image image=&#8221;34560&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221;][mk_padding_divider size=&#8221;20&#8243;][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][mk_padding_divider][\/vc_column][\/vc_row][vc_row el_class=&#8221;home-waarom-nedzink rij-wit-schaduw&#8221;][vc_column width=&#8221;1\/2&#8243;][mk_padding_divider size=&#8221;20&#8243;][vc_column_text css=&#8221;.vc_custom_1632294158510{margin-bottom: 0px !important;}&#8221;] Zinc cappings Zinc cappings made from NedZink material can be applied successfully as a covering to the roof edge of flat roofs that are covered with bituminous, plastic or rubber material, whether or not with gravel or terrace tiles as a load.
