Commercial Roofing Tauranga

A Commercial Roof Is a Different Problem

The roofing itself is not that different. What is different is everything around it: the building has to keep operating, there is stock or equipment underneath that cannot get wet, there are staff and customers on site, and somebody has to justify the spend to a board, a committee or a landlord.

So a commercial job is mostly a planning job. We work out the sequence first - which sections come off in which order, where the crane or hiab sits, when the noisy work happens, how the building stays weathertight overnight - and then we do the roofing. Getting that right is what stops a re-roof from costing you more in disruption than it costs in invoices.

What We Do

• Commercial and industrial re-roofing. Warehouses, factories, workshops and distribution buildings, in stages if the building has to keep running.
• New commercial roofing. Working to a main contractor's programme on new build and fit-out projects.
• Packhouses and rural commercial buildings. Common work for us out through Te Puna, Katikati and Te Puke, where the roof is effectively the whole building.
• Retail, hospitality and office buildings. Where the work has to happen without closing the doors.
• Schools, community and body corporate buildings. Including phased work scheduled into term breaks or around residents.
• Roof and gutter maintenance programmes. Scheduled inspection, gutter clearing and repair, so problems get found before they become a claim.
• Internal gutters and box gutters. Often the single biggest risk on a commercial building, and the most common cause of serious water damage inside one.

The Things That Go Wrong on Commercial Roofs

Commercial roofs fail differently to houses, and almost always in the same few places:

• Internal and box gutters. A domestic gutter that overflows drips down a wall. An internal gutter that overflows empties into the building. They need to be sized for real rainfall intensity, kept clear, and given proper overflow provision.
• Plant penetrations. Every air conditioning unit, extract fan, cable tray and pipe added over the years is a hole through the roof, and they are very often added by someone who is not a roofer.
• Long low-pitch runs. Big commercial roofs are shallow, which means water moves slowly and any ponding or debris matters far more than it would on a house.
• Deferred maintenance. Nobody goes up on a commercial roof unless something is wrong, so the first anyone hears about it is a leak over the stock.

Access, Safety and Documentation

Commercial sites need paperwork as well as roofing. We plan and document the access and fall protection for every job, coordinate with your own site requirements and inductions, and work in with a main contractor's health and safety system where there is one. If your building has an asset management plan or your insurer wants a condition report, we will provide photographs and a written assessment rather than a one-line invoice.

Getting a Price

For anything of size we will come out, get on the roof, and put together a proper written proposal: scope, product specification, sequence, programme, access and cost, broken down so it can be presented to whoever signs it off. If the building can be done in stages across two budget years we will price it that way and tell you which sections are most urgent.
