EXCELLENT Based on 100 reviews Posted on Mandy McLellanTrustindex verifies that the original source of the review is Google. We were lucky enough to reach Martin to help with a roof assessment of a home we're hoping to purchase. He was extremely fast and communicative, arranging the inspection the same week. His team arrived on time, produced the report and quotation later that day, and were available for a call to discuss the details. Incredible service, couldn't recommend them more!Posted on Prakash InaniTrustindex verifies that the original source of the review is Google. We had a roof leakage issue and MJ Roofing and More were absolutely fantastic from start to finish. Mercin and the whole team were professional, responsive, and very reassuring during what could have been a stressful situation. They quickly identified the root cause of the leak, explained everything clearly, and fixed it efficiently with great attention to detail. The work was done to a very high standard and the area was left clean and tidy afterwards. We’re extremely happy with the service and would highly recommend MJ Roofing and More to anyone needing roofing repairs or maintenance. Thank you again!Posted on Catherine NestorTrustindex verifies that the original source of the review is Google. They are professional roofers. Excellent service, work, tidiness. Extra, unplanned work done without any delays. I can only recommend them.Posted on Mary O'CallaghanTrustindex verifies that the original source of the review is Google. This was our second time to use MJ Roofing and once again we were very happy with their work. We had to have our extension roof replaced due to bad workmanship by a builder. We knew from previous experience that MJ Roofing could be trusted and we now have a warm, dry and well insulated roof. Marcin and his crew, in particular, Leszek and Jarek, were a pleasure to deal with. We would highly recommend MJ Roofing.Posted on Breda BruntTrustindex verifies that the original source of the review is Google. Great quality work by Marcin and his team. They were extremely professional and the work was completed on time and to a very high standard. Update April 2025 - we’ve just had the team out again to do another job and once again their work was excellent. I would highly recommend them to anyone.Posted on Maura KellyTrustindex verifies that the original source of the review is Google. Initially I had a badly leaking porch to deal with. Water was pouring down the inside of the walls. Marcin was there quickly to inspect and once work was started it was done in no time. Photos were taken of the roof to show what was wrong and what would be done. I wouldn’t hesitate to work with this business again. Update: I got Marcin and his team back to do some more work in 2025 and again I can’t recommend them highly enough. Efficient and professional and very helpful.Posted on robert doyleTrustindex verifies that the original source of the review is Google. Martin and team were extremely easy to deal with. They arrive on time are very knowledgeable and keep you informed as they work. Very professional in every aspect of the job. I especially liked how Martin would update if any extra work was required before proceeding so you know exactly where you stand at all times. I’d highly recommend Martin and his team.Posted on karen noonanTrustindex verifies that the original source of the review is Google.

What's Included in a Commercial Roof Installation

Site survey and roof assessment

Planning & Disruption Control
Commercial roof installations require careful planning to minimise disruption to your business operations. Before work starts, we assess site access, identify safe routes for materials and equipment, and plan safe working zones that keep entrances, walkways, and parking areas accessible where possible.
For larger projects or buildings with occupied tenants, we can carry out staged or phased works — completing the installation in sections to reduce noise, limit access restrictions, and keep parts of the building fully operational throughout. We maintain clear communication with facility managers, property agents, or site contacts throughout the project, providing progress updates and flagging any issues that may affect building users.
Where appropriate and agreed in advance, we can schedule out-of-hours work to avoid peak business times — though this depends on the scope, access, and any noise or safety restrictions on your site. Our goal is to deliver a quality roof installation with minimal impact on your day-to-day operations, while maintaining a safe, tidy, and organised site at all times.

Call for a survey and quote — we’ll assess your roof and provide clear recommendations.
Common Reasons Commercial Roofs Need Replacement
Not all commercial roof issues can be resolved with repairs. Here are signs that replacement or refurbishment may be the better option:
Recurring leaks across multiple areas
Widespread membrane wear or cracking
Ponding water or drainage failures
Failing edges, parapets or upstands
History of repeated patch repairs
Storm damage across large sections
Roof plant penetrations causing persistent leaks
Age of roof system (20+ years for many systems)
Water ingress causing internal damage
Roof reaching end of serviceable life
We can assess your commercial roof and advise whether targeted repairs or full replacement is the most cost-effective solution.

Frequently Asked Questions
How do you plan a commercial roof installation to reduce disruption?
We start with a site visit to assess access, identify safe routes for materials and equipment, and plan working zones that keep entrances, walkways, and parking areas accessible where possible. For larger projects or buildings with occupied tenants, we can carry out staged or phased works — completing the installation in sections to reduce noise, limit access restrictions, and keep parts of the building operational throughout. We maintain clear communication with facility managers, property agents, or site contacts, providing regular progress updates and flagging any issues that may affect building users. Our goal is to deliver a quality installation with minimal impact on day-to-day operations while maintaining a safe, tidy site.
Do you provide a written scope and quote?
Yes, always. After our site survey, we provide a written scope that outlines the work required, the materials we’ll use, the project timeline, and a clear breakdown of costs. The quote is fixed — what we quote is what you pay, with no hidden extras. If any additional work is identified once we start (such as unexpected substrate issues), we’ll let you know and provide a revised quote before proceeding. Everything is documented upfront so you know exactly what to expect. For larger projects, we can also provide phased pricing if you’re planning the work in stages.
Do you assess drainage and outlets as part of the install?
Yes, drainage is a critical part of any commercial flat roof installation. Before we start, we assess the condition and capacity of existing outlets, check for blockages, and evaluate the roof’s falls and drainage design. Poor drainage is one of the most common causes of commercial roof failures — ponding water accelerates membrane wear and can lead to leaks. If we identify drainage issues during the survey, we’ll recommend solutions such as outlet upgrades, improved falls, or additional drainage points. Proper drainage detailing is included in every installation we carry out to ensure long-term performance and prevent future water-related problems.
Can you carry out phased works?
Yes, phased works are often the best approach for larger commercial buildings or occupied sites where disruption needs to be minimised. We can complete the installation in sections — for example, working on one wing or zone at a time while keeping other areas fully accessible and operational. This allows businesses to continue trading, tenants to remain in place, and site access to be maintained throughout the project. Phased works do extend the overall project timeline, but they provide flexibility and reduce the impact on building users. We’ll work with you to plan a phasing schedule that suits your operations and site requirements.
Do you offer out-of-hours work?
Where appropriate and agreed in advance, we can schedule out-of-hours work to avoid peak business times and minimise disruption. This depends on several factors: the scope of the work, site access arrangements, noise restrictions, and health and safety considerations. Some commercial roof installations can be carried out outside normal working hours, but others (especially those requiring hot works, heavy equipment, or scaffolding) may not be suitable due to safety or noise constraints. If you need out-of-hours work, let us know during the planning stage and we’ll assess whether it’s feasible for your project. We’ll always be upfront about what’s realistic and safe.
Are you insured for commercial roof installation work?
Yes, we carry full public liability insurance for all commercial roofing work, including new installations, refurbishments, and roof system replacements. This protects your property, building users, and any third parties while we work. Commercial roof installations often require scaffolding, lifting equipment, and access to occupied buildings, so proper insurance cover is essential. You can ask to see our insurance documentation at any time. We also follow strict health and safety procedures on every site, including risk assessments, method statements, and safe systems of work tailored to each project.
Do you provide photo updates or documentation?
Yes, we can provide photo updates at key stages of the project if requested. This is particularly useful for property managers, landlords, or clients who need to report progress to stakeholders or maintain records for insurance or compliance purposes. At project completion, we provide handover documentation that includes a summary of the work carried out, any maintenance guidance relevant to your roof system, and photos showing the finished installation. For larger projects, we can also provide more detailed progress reports or site meeting notes if needed. Just let us know what documentation you require when we’re quoting for the work.
