When you get in touch with Alliance Roofing London, here is what happens next. First, we arrange a free site survey — typically within 24–48 hours of your enquiry. Our surveyor will assess the condition of your roof, identify any problem areas, and discuss the best course of action with you. You will then receive a detailed written quotation with a clear breakdown of costs and a realistic timeline. Once you approve the quote, we schedule the work at your convenience. Our crews arrive on time, keep disruption to a minimum, and leave the site clean and tidy when the job is complete. On completion, we carry out a final inspection and hand over all guarantees in writing.

Choosing the right alliance roofing company matters. Our team is City & Guilds qualified, fully insured with £5m public liability cover, and independently verified on both Checkatrade and TrustATrader. We use only premium-grade materials — from natural slate and clay tile to high-performance flat-roof membranes — sourced from trusted UK suppliers. Every project, large or small, carries a written workmanship guarantee. Our response time for emergency call-outs is typically under two hours anywhere in London. Pricing is transparent from the outset: we do not add hidden charges or vary costs once work has begun. As an established alliance roofing company with over two decades of heritage, we stand behind every roof we touch.
