DPR Roofing recently carried out a property inspection survey on a house in Ossett, Wakefield. The findings of which were that the property’s roof was in a very poor condition and, due to the condition of the roof, DPR’s experienced roofers recommended that a patch repair would not be possible and that the roof would need replacing in full.

The new roof project involved the roofers erecting scaffolding to the roof elevations to comply with the working at height regulations. They then stripped off the external roof covering, ridge tiles, old flashings and old roof lattes and cleaned down all of the structural roof timbers whilst de-nailing all of the rafters.

A new quality BNS747 breathable undertile felt was then installed. This negates the requirement for fixed and aesthetically unappealing roof vents which can detract from the overall appearance of a new roof covering. New pre-treated timber battens (lattes) were fit. 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 of roof lattes as is a common case on un-treated timber lattes. A new vertical valley joint with the adjoining property was added. This is a purpose made fibre glass valley trough that allows the perfect mating of two different roof coverings between a two or more properties.

To complete the new roof covering, new quality concrete interlocking roof tiles of Marley Modern type were fixed and new Code 4 leadwork was applied to the chimneystack abutments. These are sheet lead flashings that are bespoke, made on the roof site by our roof technicians to fit perfectly the masonry abutments that they are protecting from water ingress. Flashings are traditionally plugged 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 like mortar pointing does in a short period of time. Finally new ridge tiles were fit to new mortar bedding and pointed flush.
