Commercial Extensions and Conversions Need Expert Roofing

Commercial extensions, refurbishments and change-of-use conversions present roofing challenges that differ from straightforward new builds. Tying new roof sections into existing structures, matching materials on heritage or character buildings, maintaining weathertightness during phased work and meeting updated Building Regulations all require experience and planning.

Radiant Roofing handles roofing for commercial extensions and refurbishment projects across Kent, Sussex and Surrey. We work with architects, contractors and building owners to deliver roofing that meets the specification, integrates with the existing building and complies with current regulations. Whether it is a school extension, office conversion, church repair or retail unit refurbishment, we have the experience to deliver.
