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’d highly recommend Martin and his team.Posted on karen noonanTrustindex verifies that the original source of the review is Google.

Reporting & Documentation
Commercial clients need clear documentation — for your own records, insurance purposes, landlord reporting, or budget planning. After inspections or repairs, we can provide written summaries detailing what was found, what work was carried out, and recommendations for future action. This isn’t a formal certification or structural survey (we’re roofing contractors, not structural engineers), but it’s practical documentation that helps you make informed decisions.
Photo evidence shows the problem areas visually — blocked outlets, split seams, ponding water, edge flashing failures — making it easier to understand the issue and justify repair costs to stakeholders. We can structure reports to include a priority list: urgent repairs needed now, work that should be scheduled soon, and items to monitor over time. For multi-site property managers, we can adapt documentation to suit your portfolio reporting requirements.
Written quotes break down costs clearly: materials, labour, access requirements (scaffolding, cherry picker), and any specialist equipment needed. You’ll know exactly what’s included and what’s not before committing to work. If you need options — such as repair versus full renewal, or phased works over multiple visits — we provide those alternatives with transparent pricing for each approach.

Need a Commercial Roof Inspection or Urgent Leak Repair in Dublin?
Call us for rapid response where possible — we understand commercial properties can’t afford prolonged leaks.
Common Commercial Roof Issues
Ponding Water / Poor Falls
Water pooling on flat roofs due to insufficient fall towards outlets. Accelerates membrane degradation, causes leaks, blocks drainage paths.
Blocked Outlets/Drains
Debris, silt, or vegetation blocking roof outlets. Water backs up, overflows, penetrates seams. Most common cause of commercial roof leaks.
Split Seams / Membrane Wear
Felt or membrane seams splitting due to age, movement, thermal cycling. Water ingress at joints. Wind uplift exacerbates the problem.
Edge/Parapet Flashing Failures
Flashing at roof edges and parapets lifting, splitting, or corroding. Rain penetrates behind flashing, causing internal damp and damage.
Rooflight/Penetration Leaks
Leaks around rooflights, vents, pipes, or plant equipment penetrations. Failed seals, poor detailing, or storm damage creating water ingress.
Gutter/Downpipe Overflow Affecting Walls
Leaks around rooflights, vents, pipes, or plant equipment penetrations. Failed seals, poor detailing, or storm damage creating water ingress.
Storm Damage & Wind Uplift
Blocked gutters overflowing down external walls. Saturates brickwork, causes internal damp, damages cladding and windows below roof level.

Frequently Asked Questions
Do you provide commercial roof inspections in Dublin?
Yes, we provide commercial roof inspections for businesses, facilities managers, and property management companies across Dublin. Inspections include a visual assessment of the roof covering, outlets, drainage, flashings, and any visible defects. We can provide written summaries with photo evidence showing problem areas, a priority list (urgent, soon, monitor), and recommendations for repairs or maintenance. This isn’t a formal structural survey (we’re roofing contractors, not structural engineers), but it’s practical documentation that helps you make informed decisions about your property. Inspections are useful for budget planning, insurance purposes, tenant lease arrangements, or simply understanding the condition of your roof before problems escalate. See our dedicated commercial roof inspection page for more details.
Can you provide photos and a written report?
Yes, we can provide photo evidence and written reports for commercial roof work. Photos document the issues found (blocked outlets, membrane splits, ponding water, flashing failures) and show completed repairs, making it easier to understand the problem and justify costs to stakeholders. Written reports summarize findings, work carried out, and recommendations for future action — structured to suit your requirements, whether that’s internal records, landlord reporting, or insurance documentation. We can also provide itemized invoices and quotes that fit standard business accounting processes, including PO numbers if needed. For multi-site property managers, we adapt documentation to suit your portfolio reporting. Everything is transparent and documented upfront, with realistic timescales and clear breakdowns of materials, labour, and access costs.
Do you offer planned maintenance for commercial buildings?
Yes, we offer planned maintenance visits for commercial roofs. Regular maintenance helps prevent small issues becoming expensive emergency repairs — clearing gutters and outlets before blockages cause leaks, checking membrane seams and flashings for early signs of wear, and addressing minor problems during scheduled visits rather than emergency call-outs. Planned maintenance is particularly valuable for facilities managers, property management companies, and businesses with multiple sites. We can schedule visits quarterly, bi-annually, or annually depending on your building’s needs and budget. Maintenance visits include gutter clearance, outlet checks, minor repairs (re-sealing, securing loose flashings), and a brief written summary of the roof’s condition. See our commercial maintenance page for more details.
Can you respond to urgent roof leaks for businesses?
Yes, we respond to urgent commercial roof leaks where possible. We understand that prolonged leaks in commercial properties cause business disruption, damage stock or equipment, affect tenant relations, and can force closures in severe cases. While we can’t guarantee instant arrival (we’re not a 24/7 emergency service), we prioritize urgent commercial leaks and aim to respond as quickly as possible during working hours. For immediate problems, we can advise on temporary make-safe measures (covering the leak, containing water, protecting equipment below) over the phone while we arrange to attend. Once on site, we identify the leak source, explain the cause, and discuss options: temporary repair to stop the immediate leak versus scheduling permanent repairs. See our commercial roof repairs page for more on our repair services.
What affects the cost of commercial roof repairs?
Commercial roof repair costs vary based on several factors: the size and complexity of the roof (small office unit versus large warehouse), accessibility (safe ladder access versus scaffolding or cherry picker required), the type of repair needed (simple outlet clearance versus membrane replacement or flashing renewal), materials required (standard felt versus specialist systems), and whether the work can be done in a single visit or requires phased scheduling. Urgent call-outs, out-of-hours work, or difficult access naturally cost more than planned daytime repairs with clear site access. We provide written quotes detailing all costs before work begins — materials, labour, access equipment, and any specialist requirements. If you have options (repair versus renew, temporary versus permanent, phased works), we price each approach clearly so you can make informed decisions based on budget and priorities.
Are you insured for commercial roofing work?
Yes, we carry full public liability insurance for commercial roofing work. Commercial properties require proper insurance cover — your building, your tenants, and our workforce are all protected while we work. You can request to see our insurance documentation at any time. We follow health and safety procedures appropriate to commercial sites, use correct access equipment (ladders, towers, scaffolding as needed), coordinate with your site teams where necessary, and work professionally to minimize disruption to your operations. We’re experienced in working on commercial and industrial buildings across Dublin — from small retail units to large warehouses and office blocks. Your peace of mind and property protection are priorities, and we understand the responsibilities that come with working on occupied commercial buildings.
Do you work out of hours to reduce disruption?
We can work outside normal hours where possible to reduce disruption to your business operations, but this depends on the type of work, access requirements, health and safety considerations, and our current schedule. Simple repairs like clearing gutters or fixing small leaks can sometimes be done early morning, late afternoon, or weekends if that minimizes impact on your trading hours or tenants. However, noisy work (cutting, drilling), work requiring scaffolding erection, or complex repairs may need to be done during standard working hours for safety and practical reasons. We discuss scheduling options honestly during the quote process — if out-of-hours work is feasible and beneficial, we’ll arrange it; if it’s impractical or unsafe, we’ll explain why and suggest alternatives like phased work, sectioning off areas, or scheduling during quieter periods. Our goal is to complete work efficiently while causing minimal disruption.
Do you handle flat commercial roofs and roof outlets?
Yes, we specialize in flat commercial roofs and drainage systems. Flat roofs are common on commercial and industrial buildings, and outlet/drainage problems are one of the most frequent causes of commercial roof leaks. We clear blocked outlets, check drainage falls, repair outlet flashings, and address ponding water issues caused by insufficient fall or debris accumulation. We also repair felt or membrane roofs (re-sealing seams, patching splits, replacing damaged sections), edge and parapet flashings, and rooflight surrounds. Our experience includes working on various flat roof systems used in commercial buildings — built-up felt, single-ply membranes, and liquid waterproofing systems. See our flat roof repairs page and general roof repairs page for related services.
