Extension roofing joined carefully to Stockton-on-Tees homes

About this service

A new roof that belongs with the building

An extension roof must protect the new space and connect cleanly with the existing property. Available wall height, span and drainage often decide whether a pitched or flat design is practical. Pitched extensions may use tile or slate where the design supports them. GRP fibreglass, EPDM rubber and felt provide options for suitable flat layouts. We also consider how the finish relates to the original roof and walls. A technically sound roof should not look like it was chosen without glancing at the rest of the house.

The connection receives close attention

Where an extension meets the property, weatherproof detailing becomes critical. Abutment flashings, wall junctions and valleys need to direct water away from the join rather than towards it. We coordinate the covering with the insulation zone, ventilation needs and rainwater route as part of the wider build-up. Roof form and material influence the sequence, while outlets and gutters must suit the available falls. By planning those interfaces early, we reduce the chance of finding that two individually sensible details do not meet sensibly in the middle.
