How much does roof plumbing cost?

Roof plumbing is the type of service that you might not think you need - until you do. If you’re building or renovating, there’s a good chance you’ll require a roof plumber to help with a bunch of tasks. These tasks mostly involve installing or fixing roof coverings, downpipes, or guttering. But you can also do with some help from a roof plumber for any jobs involving skylights or ventilation.

With the breadth of tasks that you might need help with, it’s a good idea to scout around for different service providers and prices. This price guide can help determine how much roof plumbing costs for the tasks you require.

When should I hire someone to do roof plumbing?

So, what does a roof plumber do?

There’s a range of situations in which you might need roof plumbing. If you’re building your own house or doing significant renovations, roof plumbing services will probably be necessary if:

  • You’re considering installing a rainwater tank or rainwater collection system

  • Guttering, downpipe, and stormwater systems need to be installed or augmented

  • Your home insulation system is at risk of damage or being damaged by water 

  • You need to work out what sort of drainage system you want to install 

  • You’re thinking of putting in an entirely new roof

But there’s also plenty of occasions you might want to consider a roof plumber if you’re not doing major work to your property. Some common situations include:

  • If you have a leaky roof

  • If there’s a build-up of mould or mildew in your ceiling or walls 

  • If your property foundations are starting to shift or become unstable 

  • If you need to repair your rainwater tank or rainwater collection system

  • When you simply need to do your regular clean of your gutters and downpipes 

Works that a roof plumber does not perform

Some tasks may not fall within a roof plumber’s job description. These works are generally known as “roofing.” They include the design and installation of tiles, slates, and glass onto ceilings, as well as concrete, timber, or thatching. And you don’t need a roof plumber for this sort of task.

But sometimes it can be difficult to know who is the appropriate person for the job. Although glass fittings in ceilings tend not to be installed by roof plumbers, installing skylights and ventilators are generally jobs for roof plumbers. There are situations that you might need to engage both roof plumbers and roofers.

Should I attempt to do the job myself?

Probably not. And in some cases definitely not.

There are extensive regulations and qualifications needed to perform roof plumbing. These regulations exist for good reasons: to protect clients from unskilled work, as well as to protect roof plumbing workers. It can be dangerous up there.

Without training and decent scaffolding, there are significant risks in trying to manage roofing situations as an enthusiastic amateur. That risk is compounded when you’re dealing with plumbing and water systems located close to electricity infrastructure.

It will always be tempting to take on simple jobs yourself, such as fixing leaks. And there’s nothing necessarily wrong with taking it upon yourself to keep your guttering clean. In theory, it’s just good habits to remove leaves if you see them. But it’s also difficult, of course, to get onto most roofs. You might not know if your roof can support your weight.

Rather than assume that you’ll be able to fix any issues as they arise, it might be worth accepting that it often works out simpler, safer, and cheaper to simply book in semi-regular roof plumbing check-ups.

What qualifications do roof plumbers have?

The UK provides a list of qualifications for licensed roof plumbers. But there is some flexibility. Roof plumbers can have a British Board of Agreement (BBA) certification. But they can also have a general plumbing certificate with a roofing specialisation. 

What questions should I ask for roof plumbing?

There’s a whole host of things that you might want to ask for your roof plumbing, depending on the size of the job you’ve hired them or are considering hiring them for. 

One question you might want to ask a roof plumber is whether they have a plumbing licence and what qualifications is it based on. 

A second question is their method of charging: are they proposing to bill you by the hour, the volume of work that needs doing, or by the task? 

A third question is whether or not they’ll supply their materials. Depending on what you need, the cost of new drainage materials can add significantly to the overall price of roof plumbing work. You also might want to know about their level of insurance coverage - roof plumbing can be risky and has the potential to cause damage elsewhere if not done properly.

What are the risks of putting off roof plumbing work?

Roof plumbing is sort of like going to the dentist. You might think you can go a long time avoiding it, but hold out too long and you’ll regret it.

One of the main risks of avoiding roof plumbing work for a serious length of time is that moisture from poor roof drainage systems will get into the walls and structure of your home. In a bad case, this could lead to serious structural damage and even potentially dangerous electrical faults.

But even more modest cases of water damage and roof leaks can still lead to extensive repair bills if not corrected quickly. Given the increasing prevalence of extreme weather, it will probably pay to keep on top of your roof plumbing issues.

Estimated costs of roof plumbing  

The amount you’ll pay for roof plumbing services will depend on a bunch of factors. One of those is the size of the job you reckon will need doing. But another is the type of roof plumbing task. Generally, maintenance jobs like gutter cleaning will cost a fair bit less than tasks requiring more training, such as gutter installation.

FAQs

As a rough guide, expect roof plumbing work to cost upwards of $50 per hour and often closer to $100. But if it’s a more important job, you might be able to work out a fixed price with the roof plumber. In which case, the price might work out to be less. The average hourly rate for a plumber in NSW is around $75.
Roof plumbers are also likely to quote on a per metre basis. That is, they’ll quote you based on the size of the job you need to do - a longer stretch of guttering or downpipes that need fixing will attract a higher quote. The final price you can expect to pay will ultimately hinge on a bunch of factors. The skill level of the plumber is one. Another is the level of damage or work required. A third is whether or not they’ll need to supply the materials or if you can provide them yourself. A fourth is the size of the job. And a fifth is your location; expect to pay more if the plumber has to travel a distance to get to you.
For a proper gutter clean, you might be able to pay around $100 but expect to fork out more for larger gutters. But prices can rise quickly after that. Silicone repairs could add a bit to the price. And for new build roof plumbing work, the cost of installing a new colorbond roof can easily exceed $3000.
A fair price will ultimately be whatever both you and your roof plumber are comfortable with. But given that roof plumbing is an essential - yet not obvious - aspect of home maintenance, it might be worth not trying to be too economical. It might be worth adding a few extra tasks to the list you provide your roof plumber so that all the little jobs can be done.
