Practical guidance
Use these practical guides to understand residential roofing, roof refurbishment, surveys, repairs, insulation, flat roofs, slate, leadwork, storm damage, heritage properties and carefully managed refurbishment before deciding the next step.
The aim is to help private homeowners and professional project teams ask better questions before work begins. Good roofing decisions usually depend on the property, the visible condition, access, previous repairs, materials, junctions and the level of investigation available.
Use these guides as general guidance rather than a substitute for a roof survey, legal advice, planning advice, structural advice, conservation advice, insurance advice or other professional input where those matters apply.
Use the guides to prepare useful information before making an enquiry: the property address, roof type, visible symptoms, photographs where safe, known history, project stage and any drawings, reports or approvals already available.
