W & W Roughcasting, Roofing and General Builders Ltd

W & W says it works on both commercial and domestic flat roofs, from brand-new roofs to replacements and repairs. The two flat roofing types described on its website are EPDM rubber roofing, which it calls flexible with a seamless finish and a long lifespan, and three-layer torch-on felt, which is melted into place with a blowtorch so it bonds with the existing roof surface.

Yes. The business says all new roofing work is supported by a 10-year guarantee and that all repair work comes with a money-back guarantee. For repairs, it says it gives a verbal and text quote first, then a written quote by email once you decide to go ahead. One reviewer says their roof work came with a 10-year guarantee.

W & W's roughcasting page covers roughcast, dry dash, pebble dash, wet dash and smooth render, and the business says it also carries out patch repairs. It explains that roughcast uses larger stones for a textured finish, dry dash uses smaller pebbles for a smoother finish, and wet dash mixes the chips, sand and cement before it is applied to the wall. Smooth render gives a polished finish, but the website notes it is less durable than roughcast or wet dash and may need more upkeep.
