How to get a domestic re-roof right

JOHN BRASH CASE STUDY Bridlington

A domestic re-roof in an exposed coastal location.

This plain tile roof project in Bridlington was far from a simple project as the exposed coastal location also made the selection of materials really important.

The house was built in 1915, and although it’s not listed, it is located within a conservation area.

Work on the house included building into the roof and adding a number of roof windows.

Previously a domestic re-roof would fall outside of building regulations, but as this project was both a complete re roof and building into the roof the work fell under the requirements of building regulations.

This domestic roof contains nearly every feature that a plain tile can have including

• Valley
• Hips
• Bonnet
• Ridges

John Brash believe that every roof, not just new build, should use graded battens to improve safety, quality and time onsite; but importantly to comply with current regulations – why take a chance for a few pounds?

All other roofing materials meet current British standards, battens should not be any different.

Tips from roofer Matt Timby

Roofer Matt Timby worked on this project in Bridlington and here are his tips from the project to show how to complete roofing works safely and to current regulations.

• The 99 year old Silverdale tiles were removed from the roof, checked and stored for reuse. The roof was kept dry during the works using tarpaulin.
• As was common at the time of the original build there was no felt or underlay, tiles had lime mortar applied to the underside to wind and waterproof the roof.
• Next the old batten was stripped off the roof
• The new Velux windows, 2 of which were CABRIO® Balcony’s were installed.
• The insulation was upgraded to conform to current building regulations and Proctor roof shield underlay installed.
• JB-RED 25 x 38 roofing battens, machine graded to BS5534 were then installed
• Then any old mortar was chipped of and the old tiles were re-used. Sandtoft tiles were used to match in where required.

The project shows the benefits of using high quality products

• save time onsite
• conform to Building Regulations
• meet British standards
