Where a Commercial Roof Actually Fails
On a commercial building the drainage is usually the weak point rather than the sheeting. A large roof sheds an enormous volume of water into box gutters and sumps that sit inside the building line.
When one of those backs up, the water does not go over the edge. It goes into the building, onto whatever is stored below, and it does it fast.
Older buildings are frequently the worst, because the roof has been extended or re-covered over the years without anyone recalculating whether the drainage can still carry what is now draining into it.

Sized and Built for the Roof Above It
We calculate the drainage against the actual roof area and install or replace the box gutters, sumps, rainheads and downpipes to suit, with overflow provision where the design needs it.
On repairs, we work out why it is failing first. Re-forming falls, upsizing a rainhead, replacing a corroded sump or clearing a design fault solves the problem properly rather than treating the overflow.
This is roof plumbing, which is our trade rather than a sideline. Our team brings more than 30 years of combined experience and we work across Victoria on projects of a suitable size.

I found Ben and Alex on google to redo my gutters, from start to finish they were upfront and honest. They got the job done in no time and I couldn't be happier!

First class-Alex and the team were friendly, professional, and did what they said they would do. Couldn't fault them on our re-roofing project at a community kindergarten.

Alex of Vic Metal Roofing recently replaced all the flashing on our garage roof and chimney to due to water leakage to meet current standards. The results exceeded our expectation, excellent workmanship, professional customer service and informative on the solution. Communications throughout the process from quotation to the works carried out was clear and concise. Also left everything neat and tidy. Based on our recent experience, we would highly recommend Vic Metal Roofing for their quality, service and overall value for money. 🤗

Commercial Drainage Questions
Because they carry a huge volume, they sit inside the building line where a failure is immediately a problem, and on older buildings the roof has often been extended without the drainage being recalculated.
Yes. Box gutters, sumps, rainheads and downpipes can be replaced or upsized as their own project, and on a roof with life left in it that is frequently the highest value work you can do.
Where the design requires it, yes. Overflow provision is what stops a blocked outlet becoming water inside the building, and on a box gutter it matters a great deal.
Cleaning is not a service we promote on its own. Clearing debris is part of a scheduled maintenance program, where we are also checking the condition of the drainage while we are up there.
Less than a re-roof, generally. The work is concentrated along the gutter lines rather than across the whole roof, though access equipment is still required and some areas below may need clearing.
