DPR Roofing Huddersfield recently completed a project involving the removal and replacement of a new roof on a house in Netherton, Huddersfield.
Prior to constructing the new roof DPR initially stripped and disposed of the existing external roof covering, ridge tiles, old flashings and the old roof lattes. Then cleaned down all the structural roof timbers and de-nailed all rafters.
Before fitting the new concrete interlocking roof tiles DPR installed new quality BNS747 breathable under tile felt. This felt negates the requirement for fixed and aesthetically unappealing roof vents which can detract from the overall appearance of a new roof covering. Then DPR fitted new pre-treated timber battens (lattes). These are horizontal timbers required to ‘hang’ and fix the new roof material to. It is important that these are treated to remove the possibility of de-fibre taking place as is a common case on un-treated timber lattes.
New code 4 leadwork was fitted to the chimneystack abutments. These are sheet lead flashings that are bespoke made on the roof site by DPR roof technicians to fit perfectly the masonry abutments that they are protecting from water ingress. Flashings are traditionally plugged (fixed) and pointed off with a lead mate compound which is a material sealant that has the same thermal movement as sheet lead and therefore does not split or crack in a short period of time like mortar pointing does. To finish the roof DPR fit new ridge tiles and pointed flush to new mortar bedding.
