Roofing Advice

Guides & advice from your local roofers

Costs, repairs, emergencies and honest advice on keeping a roof sound. We cover Orpington, Bromley and South East London. Every guide cites the sources behind its figures, so you can check them yourself.

These guides answer the roofing questions we're asked most often. They cover what a new roof costs in Orpington and Bromley, and how to tell a repair from a re-roof. Similarly, others look at flat-roofing and guttering problems, and one covers choosing a roofer you can trust.

While you might be dealing with an urgent leak, or planning a full re-roof, one of these guides should explain what to expect.

We research each guide from published UK sources, such as trade cost guides, the Planning Portal and GOV.UK. We link to them wherever we quote a figure or a rule. We also keep the advice focused on homes across Orpington, Bromley, the Crays and South East London. As a result, you get guidance you can check for yourself, not vague claims.

Not sure where to start? The guides on costs and on choosing a trustworthy roofer are a good place to begin. Most homeowners ask about these first. Still, for anything more specific to your roof, our contact page is the quickest way to reach us.

We publish new guides regularly, so the list keeps growing over time. We can't cover every roofing problem here. Even so, these guides are a useful starting point for understanding the roof over your head. That's true whether it's a period semi in Chislehurst or a modern estate in Petts Wood.
