Roofer London — Commercial & Domestic Roofing Specialists
Colin Welch Roofing is a roofing company working across London on commercial and domestic buildings — mastic asphalt, felt roofing, asphalt flooring and everyday roof repairs, all handled by one experienced team.
A Roofing Company London Property Owners Rely On
A roof only gets your attention when something goes wrong — a damp patch on a ceiling, a pool of water that will not drain, a covering that has simply run out of years. When that happens you want a roofer in London who turns up, explains what they can see, and gives you a straight price for putting it right.
That is the job we have been doing for more than 40 years. Our roofers strip, patch and re-lay coverings on buildings right across the capital, from terraced houses and garage roofs through to schools, offices, industrial units and government premises. Whatever the building, the work is carried out by time-served tradesmen using industry-approved materials and certified techniques.

Commercial Roofer London
Commercial roofs have to keep working while the building underneath them does. We plan commercial roofing work around your operating hours, keep sites tidy and safe, and phase larger projects so that offices, schools and production areas stay usable.
Our commercial experience covers flat roof coverings and renewals, asphalt walkways and podium decks, industrial flooring, plant room roofs, and planned maintenance for landlords and facilities teams across London.
Commercial Roofing ServicesDomestic Roofer London
For homeowners, the priority is usually a roof that stops leaking and stays that way. We handle flat roofs on extensions, garages, porches and dormers, balcony and walkway waterproofing, and the pitched roof repairs that come with older London housing stock.
You will get a clear explanation of what we have found, a written quote, and a team that treats your home with respect while the work is underway.

London Roofer — Frequently Asked Questions
What areas of London does your roofer service cover?
We work across London and the surrounding boroughs, including Lambeth, Croydon, Mitcham, Bromley, Epsom, Wandsworth, Twickenham, Sutton, Richmond upon Thames and Merton. If your property sits just outside those areas, call us and we will confirm whether we can reach you.
Do you work on commercial as well as domestic properties?
Yes. Our team works as a commercial roofer in London on offices, schools, industrial units and government buildings, and as a domestic roofer on houses, extensions, garages, porches and balconies. The same roofers and the same standards apply to both.
How long does a mastic asphalt roof last?
Mastic asphalt has a working life of up to 60 years. It is laid as a continuous, seamless covering, so there are no joints or seams for water to find, which is why it is so widely specified on London flat roofs, balconies and walkways.
Can you repair an existing roof rather than replace it?
Often, yes. We will inspect the roof first and tell you honestly whether a repair will hold or whether a new covering is the better long-term option. Repairs, patching and refurbishment of existing asphalt and felt roofs are all part of what we do.
How do I get a quote from your roofing company in London?
Call us on 0800 612 8773, email info@colinwelchroofing.com, or send an enquiry through our contact form. We will arrange a visit to look at the roof and give you a written, no-obligation quote.
How much experience does your roofing team have?
Colin Welch Roofing has been renewing, repairing and replacing roofs for over 40 years. Our tradesmen have worked on private, commercial, industrial and government properties throughout London during that time.
