A full survey was completed at a property in Headingley, Leeds recently after DPR Roofing were asked to visit with regards to the condition of the rear elevation roof coverings. Upon inspection it was noted that the old tiles were of a poor state of repair and given the age and type of property the only cost effective works would be to re-cover the roof in full.
The works involved roofers erecting scaffolding to the roof elevations for the working at height regulations. They then proceeded to strip down all external roof coverings, ridge tiles, old flashings and old roof lattes. All structural roof timbers were cleaned down and the rafters were denailed.
A new quality BNS747 breathable undertile felt was applied. This negates the requirement for fixed and aesthetically unappealing roof vents which can detract from the overall appearance of a new roof covering.
New pretreated timber battens (lattes) were installed. 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 adjoining property was also installed. 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.
The roof was covered with new quality concrete interlocking roof tiles of Marley Modern type and new Code 4 leadwork to 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 (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 like mortar pointing does in a short period of time.
Finally the roof was finished with new ridge tiles fit to a new mortar bedding and point flush. The ridge tiles were made colour matched as near as possible to the new roof finish.
