One survey, one contract, a dry building

A failing roof rarely stays a roof problem. Water reaches stock and tenants, the dilapidations schedule grows, and the EPC stays where it is.

We survey the roof, tell you plainly whether to repair, overlay or replace, and deliver the work under one contract. As curtain walling contractors, the same team also renews rainscreen facades and windows. Your building stays open while we work. Upload a roof survey, a dilapidations schedule or phone photos, and a director replies with the next step.

We work across London and the UK, from Aldgate, Kensington and Bethnal Green to Banbury and Manchester. See all locations.

Commercial and industrial roofing, roof repairs and curtain walling, under one contract

Roof, walls and glazing handled by one team, so the envelope is signed off once. Part of our dilapidations, Cat A and MEES works.

Flat roof with a light membrane covering, seen from above, with edge guardrail

Strip and re-roof

Old coverings stripped to the deck and replaced in built-up felt, single-ply, standing seam or composite panels, insulated to current standards.

Corrugated metal roof sheets with ventilation units and an open section

Overlay and over-sheeting

Where the deck is sound, a new insulated roof goes over the old one, so the building never opens to the weather.

Flat office roof with plant and a small team, seen from above

Repairs and leak tracing

Leaks traced to their source and fixed: failed laps, flashings, outlets and gutters, before water reaches stock or tenants.

Sawtooth industrial roof with glazed rooflight panels, black and white

Rooflights and roof safety

Fragile rooflights replaced, with edge protection, safety lines and walkways so every future inspection is safe.

Rows of solar panels on a large flat commercial roof

Roofs ready for solar

Structure checked and the roof renewed to outlast the panels, ready for our commercial solar team.

Facades, curtain walling and windows

Rainscreen panels, curtain walling and windows replaced or over-clad, sealed and insulated, while the building stays occupied.

How it works

How a roof or facade project runs with us

01

Send what you hold

Survey reports, the surveyor's schedule, the current EPC, drawings or photos taken on a phone. Any one of them is enough to start.

02

Survey and cost plan

We walk the roof and elevations, record the defects and recommend repair, overlay or replacement. A cost plan and a programme counted back from your date follow, free.

03

Consents and safe access

Asbestos survey, building control, landlord and tenant notices, scaffold, edge protection and crane lifts arranged before anyone works at height.

04

Sections, sealed daily

The roof is opened one section at a time and made watertight at the end of each day. Loading bays, deliveries and tenants carry on below.

05

Handover and guarantees

A walk-round with you, every defect closed, and one handover pack with the roof guarantee and certificates.

What to plan before roof or facade works in a building that stays open: access, sequencing, sign-offs and the handover file.

Our promises

Six promises, written into your contract

  1. One contract for roof and walls

    Roofing, cladding, glazing, drainage and approvals sit under one contract, with one director answerable for the whole envelope.

    Portsoken House, Aldgate: 1,550 sq m refurbished under one contract with tenants in occupation throughout.

  2. The agreed sum stands

    Any change, including rotten deck found once the roof is opened, is priced and approved in writing before work goes ahead.

    Every Craftex project to date has finished on budget.

  3. Your business keeps running

    Work is phased around loading bays, shifts and tenants, and nothing is left open to the weather overnight.

    Banbury, Oxfordshire: a working warehouse kept operating while we built inside it.

  4. Finished by your date

    The completion date is set from your lease event, letting launch or solar start, and written into the contract.

    Drake's, Bethnal Green: 500 sq m of railway-arch warehouse designed and built in 8 weeks.

  5. Cover your landlord and insurer expect

    £10M public liability and £10M employers' liability, professional indemnity on request, ISO 9001, 14001 and 45001, and CHAS.

    The accreditations shown at the foot of this page.

  6. Zero snags, every guarantee on file

    The system guarantee, fall-arrest test records, as-built drawings and the O&M manual arrive together at completion.

    Beaumont House, Kensington: 750 sq m handed over in three weeks with zero snags.

AreaThe usual riskWith Craftex
ResponsibilityA roofer, a cladder and a glazier on separate orders, and every leak at a junction becomes someone else's problem.One main contract covers the roof, the walls and every joint between them.
The final billThe roof is stripped, wet insulation and rotten deck appear, and the price starts to climb.Deck and insulation checked before pricing, and a rate for hidden repairs agreed up front.

Commercial roofing and facades, your questions

Commercial roof repairs, overlay or full replacement: which does my roof need?

Repair when the leaks are local and the rest of the covering is sound. Overlay when the deck and insulation are dry but the waterproofing has reached the end of its life. Replace when the insulation is wet, the deck is failing or leaks keep coming back. Only a look at the deck and insulation settles it, and our survey costs nothing.

Can you re-roof while the building stays in use?

Yes, and most of our clients need exactly that. Sections over loading bays, production lines or tenants are timed around shifts and agreed with your site team. Exclusion zones sit below any overhead work, and the roof is never left open overnight. At Banbury, new welfare and storage space went up inside a busy warehouse while it kept working.

Should I replace the roof before installing solar panels?

Yes, if the roof has less life left than the panels. An array is designed to stay for 25 years or more, and lifting it to re-roof later means paying for removal and refitting. Since June 2026, MCS installation standards require a check of the roof structure before panels go on. We renew and prepare the roof first; the panels follow through our commercial solar installation service.

Should I choose curtain walling or window replacement?

It depends on how the facade is built. Curtain walling is a glazed aluminium skin hung off the frame across several floors; windows sit in openings in a solid wall. Sealed glazing units are expected to last about 25 years according to GreenSpec, and sealants often less, while the frame lasts far longer. So a sound curtain wall can sometimes be reglazed and resealed rather than replaced. New windows and curtain walling must reach a U-value of 1.6 under current Building Regulations. Cladding on residential blocks over 11 metres is covered by our fire stopping and cladding remediation service.

What is in the free roof survey and cost plan?

Upload what you have: a roof survey, a dilapidations schedule, an EPC or phone photos. We inspect the roof and walls, photograph each defect and tell you whether to repair, overlay or replace. You then receive a cost plan and a programme to your date. There is no charge and no obligation.

How long does it take to re-roof a 5,000 m² warehouse?

It depends on the roof system, access, the state of the deck and the weather. A large roof is worked in sections, each one made watertight before the crew stops for the day. Materials and access are booked before any covering comes off. After the survey we write the completion date into the contract, with weather time already allowed.

Will a new roof improve my EPC and help with MEES?

Usually, yes. Replacing more than half of a roof means insulating the whole roof to current Building Regulations, where that pays back within 15 years. For a flat roof the target is a U-value of 0.18. A let commercial building needs EPC E or better today. The government has confirmed a target of EPC B from 2031 for rented buildings over 1,000 m², not yet in law. An accredited energy assessor models the gain, and our guide to MEES rules for commercial property tracks the dates.

Who pays for the roof at the end of a commercial lease?

It depends on who holds the repairing covenant. On a full repairing lease the tenant usually owes repair, and courts have accepted repair instead of replacement where that meets the covenant. Where the landlord holds the roof, a leak can be expensive: in a case reported by law firm Brodies in January 2026, a warehouse tenant recovered £147,000. Your surveyor sets the claim, and we price and carry out the works. Our guide, dilapidations explained, sets out how claims work.

What guarantees do I get on a new roof?

You get a written guarantee for the roofing system, with its length set out in your quotation. The building contract adds a defects period on our workmanship. At handover you also receive the O&M manual, drawings of what was built and every test certificate. Keep the file: an insurer, a buyer or a solar designer will ask for it.

Do you work outside London?

Yes. We are based in London and work across the UK, with projects in Manchester, Banbury and across the capital. Building Regulations differ in Scotland and Wales, and we plan the works to the local rules. Warehouses, retail parks and offices anywhere in Britain can book the same free survey. We take on roofing and facade works from £100,000.

What our clients say

See all reviews on Google
  • Hired Craftex for our conversion project. We had to convert a 600m2 office into 8 apartments. Guys did an excellent job in terms of program efficiency and quality of the finishes which gave us a big upside to exit the project 2 months faster than other competitors’ timelines.

    Misha Levit

  • Great experience from start to finish. Communication was clear, the workmanship was excellent, and the whole project was managed professionally.

    Rhea Langford

  • I’d like to thank the team at Сraftex for the work they did on our office.
    It was really important for us to get the work done quickly, but without compromising on quality, as we regularly have clients and guests visiting and needed to move into the new office within a month.
    We spent around two weeks discussing and agreeing all the details before the work started. What I really appreciated was that everything we agreed beforehand was actually followed through during the job. The work was also completed on time.
    Thanks to the whole Сraftex team for a great job. I’d definitely use them again if we need any work done in the future.

    IURII PYLYPETS

  • We recently worked with Craftex and honestly couldn’t be happier with the results. From start to finish, the team was professional, reliable, and highly skilled. The quality of workmanship exceeded our expectations, and everything was completed on time and to a very high standard.
    Communication throughout the project was excellent, and they always went above and beyond to make sure we were satisfied. It’s rare to find a construction company that combines professionalism, attention to detail, and great customer service so well.
    Without a doubt, Craftex is one of the best construction companies we have ever worked with. Highly recommended to anyone looking for quality and trustworthy builders.

    Adam Miah

  • Craftex has completed a range of both small and large-scale projects on our commercial property with exceptional precision and quality. Dmitriy consistently delivers courteous, prompt service and has shown great flexibility in accommodating last-minute changes to plans and timelines. I highly recommend Craftex for their professionalism and outstanding workmanship.

    Pascal Hunt

  • Great company to work with as always. Super flexible at dealing with evolving requirements and fast deployment and execution.

    Akshay Khanna

  • Hired Craftex to do the full design and fit out of my gym in Chelsea. Super efficient and fast team. They gave the best price and a proper fast track program. We managed to open in less than 6 weeks with no headaches or surprises during construction. Quality was great, we had zero snags on completion. I’ve worked with a few companies before but these guys really impressed me from project management to how they treat the client. Top GGs.

    Александр Хоменко

  • I worked perfectly with Sviat and Joe, with their architect they came up with a very smart design for our office to fit more desks and optimise the space to its maximum capacity. They also did excellent value engineering on the MEP design proposed by others, allowing us to save around £50K. The quality and speed were outstanding we finished two weeks ahead of schedule. Highly recommend these guys.

    John Smith

  • Happy with the end result. Tight timeline but they pulled it off. The team worked late shifts and even weekends to help us open the doors on schedule. Site was always left tidy at the end of the day and no surprise charges either. Good communication throughout. Would definitely use Craftex again.

    Pawel Kamionka

  • Highly recommended!
    Craftex are the kind of fit-out contractors in London you can truly trust. From the very first meeting, they understood our vision and gave practical ideas to make the most of our space. They turned our old storage area into a clean, efficient, and well-organized warehouse. The team was professional, easy to work with, and clearly took pride in their work.

    Monika Kamionka

  • We brought in Craftex to refurb our London office and honestly, they made the whole thing way easier than we expected. They listened, suggested ideas we wouldn’t have thought of, and explained everything clearly. Not the cheapest quote we got, but the end result shows why, the place looks modern, clean, and our team actually enjoys being here now. Communication was spot-on too. No chasing and confusion, deadlines were hit. If you want people who genuinely care and don’t treat your project like “another job,” I’d recommend them.

    A Google User

  • Sviat and his team at Craftex were brilliant to work with on our office redesign. From the first meeting, they took the time to understand how we actually use the space rather than just pitching generic solutions. They came back with clever, practical ideas to maximise use of the space and get more employees and desks inside . Every step was handled professionally, and the process felt surprisingly smooth for a project of this size. They finished one week ahead of schedule, and the transformation is clear — our office feels brighter, more functional, and much more welcoming. I’d happily recommend Craftex to anyone who wants a reliable design team that also makes the journey enjoyable.

    Cucu Iulian

  • We recently worked with Sviat and the Craftex team on a complete warehouse refurbishment, and the results have been outstanding. From the very beginning, their team was professional, organized, and attentive to every detail. The project was completed on time and within budget, without disrupting our day-to-day operations.

    Simone Racaku

  • My experience with Craftex was excellent from beginning to end. They took the time to really listen to what I wanted and then offered practical suggestions that made the design even better. I always felt like they cared about creating a space that worked for me, not just one that looked nice on paper. The end result is an office that feels stylish, welcoming, and very functional for day-to-day work. The process itself was straightforward, well-managed, and never stressful. I’d definitely recommend Craftex if you’re looking for office design and build services in London — they made the whole journey a positive one.

    Ion Bounegru

  • I’m really pleased with my experience working with Craftex. As a commercial construction firm, they handled everything from start to finish without any unnecessary stress on my side. What impressed me was how they suggested practical ideas that improved the design while also keeping things realistic. The communication was always clear, so I never felt out of the loop. The project ran smoothly, deadlines were met, and the end result is exactly what I was hoping for — a space that feels both functional and modern. It’s not easy finding contractors who are this reliable, but Craftex definitely proved they can be trusted.

    Taron Papoyan

  • I had an amazing experience working with Sviat and the Craftex team on our office fit-out in London. They were always professional, responsive, and quick to offer the best advice whenever decisions needed to be made. I really appreciated how they balanced style with practicality — the office doesn’t just look fantastic, it works perfectly for our team. Everything was done with care and attention to detail, and the project never felt overwhelming because they managed it so well. Communication was clear from start to finish, and I always felt involved in the process. I would happily recommend Craftex to anyone looking for a trustworthy contractor.

    Artur Dvorak

  • Craftex carried out a warehouse fit-out for us, and I couldn’t be happier with the outcome. The space has been completely transformed into a highly organized and efficient environment that makes our daily operations much smoother.
    The team was professional but also very approachable — I always felt comfortable asking questions or giving feedback. They came up with smart, practical solutions that worked perfectly for our setup, and everything was explained clearly along the way.
    The best part was how they stuck to the agreed timeline, finishing on schedule without cutting corners. It’s rare to get both quality and reliability, but Craftex delivered both.

    Roma Shchukin

  • We’re extremely happy with Sviat and the Craftex team’s work. They suggested clever ideas, managed the project efficiently, and delivered a functional, modern space. The team was easy to communicate with and very professional throughout the process!

    Polina Lysenko

  • I can honestly say our office has been completely transformed thanks to Craftex. From the very first meeting, the team was approachable, professional, and full of creative ideas that really made sense for our business. They didn’t just focus on how the space would look but also how it would work for the team day-to-day. The new layout is efficient, modern, and welcoming, and you can tell they really thought about the details. The whole process was smooth and surprisingly stress-free. They kept me updated at every stage, which gave me confidence. I’m really happy with the results and wouldn’t hesitate to recommend them to anyone.

    Mykyta Khadzhynov

  • The results from Craftex’s commercial refurbishment in London are fantastic. The team was friendly, clear in communication, and made sure the project stayed on track. The workspace now feels efficient, welcoming, and modern. Definitely a team you can trust!

    Alaa Betar

  • We hired Craftex for a commercial ground floor fit-out with 2 flats above. There were some minor co-ordination hiccups with third-party suppliers but the team kept it moving. Finish quality was strong. Kitchens and doors look great. I have already asked them for a quote on the next project.

    Ben Edell

  • These guys actually deliver. They handled our first industrial to residential conversion near Tower Bridge, turned an old warehouse into 4 modern flats. They stuck to the plan, kept the site clean and the timing was on point. No hidden extras, no drama, just a professional construction company in London that gets the job done.

    Богдан Главацкий

  • We recently hired Craftex for a commercial office fit-out project in Central London, and overall, we’re really happy with the result. There was a delay on our side with a custom glass partition supplier, but the Craftex team managed the construction schedule very professionally and kept everything on track. Their guys worked clean, respected our workspace and IT setup, and kept the site tidy throughout. If you're looking for a reliable office refurbishment company in London, I’d definitely recommend Craftex. Would use them again without hesitation.

    Ardian Beleshi

  • This was a full high-end renovation of my Victorian rental apartment in Westminster, just off Sloane Square and Belgravia. The scope included full fit-out: electrics, plumbing, a new bespoke kitchen, and a luxury bathroom refurbishment. Craftex took care of everything and made the process easy. They weren’t the cheapest, but you can tell they really know what they’re doing when it comes to prime London property renovations.
    The team was professional, organised, and genuinely seemed to care about getting everything right. I was especially impressed with the quality of the finish – the attention to detail really shows in every corner.
    I’m very happy with the results and would definitely recommend Craftex to anyone looking for reliable, high-quality renovation work in Central London.

    Наталия Цимбалюк

  • I was stressed about timing since we had bookings lined up, but they smashed it. Even worked Saturday to finish the floor. My clients love the look — the beauty salon fit-out turned out exactly how I wanted. Couldn’t have pulled it off without their help. Genuinely appreciate the way they communicated throughout the refurbishment. If you need reliable help with beauty salon design or fit-out, especially in a place like Chelsea — these are the guys.

    Rami Jusupova

  • We used Craftex for a shop-to-flat conversion in Chelsea — turning an old retail space into two rental units. Access wasn’t the easiest, but the guys handled it well, no drama. Quote was clear, no hidden extras, and they actually stuck to it, which is rare. Finish came out solid, exactly what we needed for rentals. Joe (PM) kept things ticking and communication was always on point. All in all, smooth job — would use them again for sure.👍

    Apartify Estates

  • Fuse Energy hired Craftex on the fit-out and installation of our engineering and research centre, which included electrical, heating, lighting, plumbing, and ventilation upgrades. They delivered everything to a high standard and were proactive throughout — even working weekends to help speed up the programme, despite not being contracted to. They managed last-minute changes very well, communication was clear and consistent, and the team was professional from start to finish. We’d happily recommend Craftex to anyone needing a reliable construction partner.

    Hainro Eybers

  • Holistic therapy space fit-out
    Super impressed. I had a very specific vision for the studio. calm tones, soft lighting, hidden storage etc. the craftex team just got it. build was done quicker than I expected and the guys were polite, tidy and actually listened. we had 2 snags on day one but they fixed it before the week was out. worth it for the peace of mind.

    Dariia Shvyryda

  • Made a full refurbishment and redesign of our Central London office. Fantastic work, quality service and reliable people. Can recommend it to everybody

    Nikita Nigai

  • Amazing experience with these guys. I trusted them my apartment in London and Business. They are always accurate, very professional, responsive and neat. They would always advice me right things for my best interest. I had luxury experience with them and I would definitely recommend Craftex to everyone.

    Motush Motushev

  • Could not be HAPPIER with Sviat and the Craftex team, they certainly showed me that they’re the number one office design company in London that we’ve had the pleasure of working with. They gave us a unique design just like we wanted, and we loved the first initial draft of the concept. Also have to give them props for Construction, I gave them a tight timeline as we needed to move our team in ASAP, so they pulled double shifts and I didn’t see a drop in quality. Will be to talking to the team when we move up to our next bigger office. Highly recommended A+++

    Mikhail Burdoev

  • Very professional company. Craftex did brilliant minimalistic design and completely refurbished my apartment to the highest quality.

    Vlad

  • I and my husband are very satisfied with Craftex's service and customer support. We bought a house in Hampstead and wanted to redesign and renovate it. On our initial free consultation with Sviat, we found out that we actually can do loft conversion and rear extension and add value to the property straight away.
    We worked with the Craftex design team to bring our vision to life and deliver planning approvals. At that time guys started stripping out to save time on the construction programme as we wanted to move in ASAP.
    We worked with very experienced project director Konstantin who was responsible for all aspects of project delivery from design to construction with a very good eye on details and customer care.
    We saved a lot of money by having professional advice from the start. Project management and quality at Craftex are at the highest level. Many thanks to Craftex Team.
