Honest, unedited feedback from residential and central London commercial clients across Google and Checkatrade.
★★★★★
“We needed two roofs replacing in central London on an old Victorian building — Element were very competitive on their price and handled everything professionally from start to finish. Would absolutely recommend.”
★★★★★
“Element Roofing have just completed a fortnight’s work replacing our loft insulation and re-tiling our roof around a new in-roof PV system. They have been a pleasure to deal with from start to finish.”
★★★★★
“We used Element Roofing for a survey and then repair of our box gutters and we are delighted with the work that was completed. The initial drone survey was very useful to diagnose the exact problem.”
★★★★★
“We just had our coping stones leaded and the flat roof they surround repaired and resurfaced. Element were excellent from start to finish — thanks to Daren and Danny and his helper for making this happen.”
★★★★★
“Recent repair to upstairs roof which was leaking into my son’s nursery and a replacement to an outside area. I can’t fault Clive and the team — the clearest quote, punctual, tidy, and leak completely solved.”
★★★★★
“We previously had roofers in to fix our roof leak several times and they could not work out where the leak was coming from. Darren and his team diagnosed the root cause straight away and fixed it permanently.”

06 // Roofing Technical & Cost Answers
Frequently Asked Questions
Clear, straightforward guidance on London Building Regulations, drone surveys, guarantees, and flexible 0% payment schemes.
Do I need Building Regulations approval when replacing a roof in London?
Yes. Renewing more than 25% of a roof’s surface area in England legally requires Building Regulations compliance under Approved Document L (thermal insulation) and BS 5534 (structural wind resistance). Because Element Roofing Co Ltd is registered with NFRC Competent Roofer, we self-certify our own work and issue your official Building Regulations Compliance Certificate directly — saving you separate council inspection delays and fees.
How much does a drone roof survey cost in London?
Our CAA-piloted 4K aerial drone roof surveys start from £350 across London, inspecting chimneys, box gutters, lead flashings, and flat roofs safely without £2,000–£4,000 of exploratory scaffolding. Better still, £150 is credited directly off your invoice when you instruct Element Roofing Co for any remedial works over £1,000.
Why is Element Roofing Co’s website at no1roofing.com?
no1roofing.com is the long-established official web domain and estimating desk (estimate@no1roofing.com) of Element Roofing Co Ltd (Registered in England & Wales No. 03733197, VAT GB 749 2237 15), displayed right on our Lewisham office fascia at 19 Manor Park Parade, London SE13 5PB.
Do you offer 0% interest roof finance and insurance-backed guarantees?
Yes. Every new roof comes with a written 10 to 50-year guarantee (including up to 20-year Polyroof insured flat roof warranties and NFRC/TrustMark protection). We also offer flexible monthly payment schemes — including 0% interest instalments — so essential roof replacements never have to be delayed.
