Evidence first
Answers distinguish symptoms from possible causes and use UK legislation, official safety guidance, Building Regulations, recognised industry guidance and manufacturer instructions where relevant.
Editorial standards
How our roofing answers are produced.
Useful guidance must be accurate, transparent about its limits and written for the person making the decision.
Technical review
Roofing content is reviewed by J & L Welch Roofing & Paving Services Ltd, established in 2021 with over 20 years of combined roofing experience. A website answer never replaces a property inspection or signed specification.
Continuous improvement
Review dates are displayed on answer pages. Anonymous searches that return no result help identify missing subjects; private information should never be entered into the advice search.
Core reference sources
- GOV.UK Building Regulations guidance
- Health and Safety Executive roof-work guidance
