Roofing for Croydon's Victorian Terraces and 1930s Semis

Croydon is really two roofing towns. Around Addiscombe, Thornton Heath, Broad Green and the streets off the London Road you have Victorian and Edwardian terraces, most of them under natural slate or old clay tile, with tall shared chimney stacks and lead valleys between the front and back roofs. Out towards Shirley, Selsdon and Sanderstead it is 1930s semis and detached houses with big hipped roofs in plain clay or concrete tile, bay windows with their own little tiled roofs, and a garage or extension with a flat roof on the side.

Both types fail in their own way. The older slate roofs lose nails and slates start slipping one by one, the valleys and chimney flashings go long before the slates do, and years of patching with whatever was in the van leaves a roof that leaks somewhere new every winter. The 1930s roofs were often laid without any felt at all, so once the tiles and torching go, wind-driven rain gets straight into the loft. Flat roofs on Croydon extensions are usually felt that has done its 15 to 20 years and is now blistering and splitting at the edges.

We look at the whole roof, tell you plainly whether it needs a repair or a replacement, and put the price in writing before we start. If it only needs a repair, that is what we quote.

“Being a Sergeant in the Metropolitan Police, and a Veteran of 12 years in the British Army, I'm overly suspicious and very cautious of who I do dealings with. I did an online request ... and within an hour I received a call from Cornelius, the owner of Seal Pro Roofing Ltd. ... He told me it would take 2 days, and that's exactly how long it took. ... I simply can't fault them in anyway. Great job!”

Yes. We cover the whole of Croydon, from Thornton Heath, Norbury and Addiscombe through South Croydon, Shirley, Selsdon and Sanderstead down to Purley and Coulsdon. Call 01753 330566 or book online and Cornelius will arrange your free inspection.
Not always. A lot of 1930s roofs in Shirley and Selsdon were built without felt and have lasted because the tiles are still sound. If the tiles and battens are good we can often repair and re-torch. If the battens are rotten or tiles are failing across the roof, a re-roof with a breathable membrane is the better spend, and we will show you the photos so you can see why.
It depends on what has failed and how we get to it, so we never guess over the phone. We inspect the roof, show you what we found and give you a free written quote with a fixed price. Small repairs are priced as small repairs.
Yes. We strip the old felt, check the deck and timbers, and lay EPDM rubber, GRP fibreglass or a three-layer torch-on system depending on the roof and your budget. Every flat roof is detailed into the house wall with proper flashings so the join stays dry.
Yes. Our emergency callout runs 24 hours a day. Call 01753 330566 if water is coming in and we will make the roof safe as quickly as we can, then agree the permanent repair with you.
