Who we work for

Oisin Roofing & Guttering looks after roofs on industrial units, retail units, offices, apartment blocks and mixed-use buildings across Dublin, Wicklow and Kildare, for owners, landlords, facilities managers and owners’ management companies. The work is a mix of emergency leaks, planned repairs and full replacements, and the common thread is that someone else’s business or home is under the roof, so the job is scheduled around them and photographed properly afterwards.

Flat roofs on commercial buildings

Most commercial roofs in Dublin are flat or low-pitch, and the failures are predictable: blocked outlets and ponding, torch-on felt blistering and splitting at the laps, EPDM seams lifting, and upstands cracking at parapets and plant bases. We repair in the same material where the roof has life left in it, and replace with EPDM, GRP fibreglass or a torch-on system when it does not, using Laydex, Soprema and RoofTX membranes that carry 20-year manufacturer warranties. Tapered insulation can create the falls the original roof never had, and outlets are upgraded so the roof actually drains. Larger roofs are done in sections so the building is never open overnight.

Apartment blocks and management companies

For an OMC the roof is usually the biggest single item in the sinking fund, and the decision on when to replace it needs evidence. We survey the roof, photograph every defect and list the faults in priority order with a budget figure against each, so the management agent can put a number in front of the directors rather than a guess. Common-area gutters, downpipes, flashings and rooflights are handled the same way, with before-and-after photos for the file.

Working around the building

Shops cannot close and tenants cannot move out, so we plan around the building: out-of-hours and weekend slots, phased sections, materials lifted at agreed times, and a clean site at the end of every shift. Our insurance details go on file before anyone goes on the roof.

What affects the price

Every commercial job is priced after a free survey. What moves it: the system and the roof area; how much deck and insulation has to come up; access and working height, from a tower to full scaffolding or a hoist on an apartment block; and any out-of-hours or phased working. The price is agreed before any work starts, and there are no hidden charges.

Guarantee and track record

New roof builds carry a 25-year guarantee, the membranes carry their 20-year manufacturer warranties, repairs are guaranteed, and we are fully insured. Oisin Roofing & Guttering has completed over 1,700 roofs, from small residential repairs to full commercial replacements.

FAQ

Commercial: questions we get asked

How much does commercial roofing cost?

Every commercial job is priced after a free survey, because the system, the roof area, access, insulation upgrades and out-of-hours working all change it. The price is agreed before any work starts, and there are no hidden charges.

Can you work outside business hours?

Yes. Evenings, weekends and phased work are all normal for shops, offices and apartment blocks, so tenants and trading are not disrupted. The schedule is agreed before we start.

Can you survey a roof for a management company?

Yes. We survey the roof, photograph every defect and list the faults in priority order with a budget figure for each, which is what an OMC or facilities manager needs for planning and sinking-fund decisions.

How long does a commercial flat roof replacement take?

It depends on area and system. A typical block or unit roof of a few hundred square metres is usually a one to two week job, done in sections so the building is never left open.

What warranty comes with the work?

Laydex, Soprema and RoofTX systems carry 20-year manufacturer warranties, new roof builds carry our 25-year guarantee, and repairs carry a workmanship guarantee.

Are you insured for commercial work?

Yes, fully insured, and the certificate is available for your records before work starts.
