Why Preston jobs are specified this way
Wide spread — Victorian and Edwardian terraces around Deepdale and Frenchwood, large detached homes in Fulwood, and significant commercial/industrial roofing demand around Walton Summit and Riversway.
Sheltered urban environment, but the Ribble corridor channels weather through Penwortham and Ashton — surface water and gutter overload are recurring issues.
