Are you a homeowner or builder in Australia? You’ll know how crucial roof drainage is. And you’ll know that a clogged drain or damaged one is a bad sign. Don’t worry; we’re unpacking everything building owners need to know about installing and fixing roof drains.
What Is the Purpose of a Roof Drain?
Roof drains sit around the roof, doing their best to keep water from pooling on your roof after rains or a storm. Otherwise, you may face costly leaks and damage. This small but integral part of your home gets water flow off your roof quickly and efficiently to prevent structural issues and preserve the integrity of your roof. After all, no one wants a sagging or collapsing roof.
What Materials are Roof Drains Made From?
Roof drains come in a range of different materials to handle the harsh outdoors:
- PVC (Polyvinyl chloride) is a popular and durable choice that’s affordable and easy to install
- Cast iron is heavy duty and incredible strong – suitable for larger commercial and industrial buildings
- Aluminium is lightweight and rust-resistant, making it suitable for areas with high humidity
- Copper is a sleek and stylish material that’s also long-lasting and can resist corrosion
- Stainless steel is tough – designed for extreme environments and corrosion-prone areas
Step by Step: How to Install Your Roof Drain
Does installing a roof drain sound like a daunting DIY task? With a bit of know-how and experience, you should be able to install your roof drain without trouble. And if you run into issues, consult a professional to help.
1. Choose the Right Type of Drain
You can get interior and exterior drains:
- Interior roof drains are placed in the centre of the roof, directing water through the building’s plumbing system.
- Exterior roof drains are often used on sloped roofs to direct water off the edge of the roof to the gutters.
2. Mark the Drain Location
Determine the most suitable place to put your drain. Got a flat roof? You’ll want to put the drain at the lowest point of the roof in order to make the most of gravity and ensure efficient water flow.
3. Install the Drain Assembly
Cut a hole in your chosen spot on the roof that matches the size of the drain assembly. Then you’ll need to fit the drain base and secure it – make sure that the connection is tight to prevent leaks.
4. Connect the Drain to the Downspout
Run a downspout (the pipe that carries water off the roof) from the drain to your gutters. You should slightly angle the pipe for efficient drainage.
5. Seal Everything Up
You don’t want any pesky leaks! Seal the drain and downspout connections with roofing sealant. Double-check for any gaps or weak spots.
6. Test Your Work
Test the system by running some water through it once everything is in place. It’s best to check there are no signs of leaks before the next rainstorm!
Step by Step: How to Fix Your Roof Drain
Things with roof drainage can always go wrong – no matter how careful you are with installation and maintenance. Here’s how to fix anything from wear and tear to clogged drains…
1.Identify the Problem
Firstly, you need to figure out the details of what’s gone wrong with a roof drain inspection. Common issues are typically:
- Clogs – leaves, dirt, and other debris can build up in your roof drain over time.
- Leaks – if your drain connections are not sealed properly, water might leak around them.
- Loose or damaged components – sometimes, parts of the drains, like the downspout or drain cover, can become loose or get damaged.
2. Clear the Clog
The best way to clear clogged roof gutters is by using a plumber’s snake or a high-pressure water hose. You may need to get a professional roofer to help clear clogs on larger roofs.
3. Tighten Loose Parts
Check for any loose parts and tighten them. Replace any faulty parts if you notice cracks or damage.
4. Repair Leaks
Spotted a leak? You need to reseal the joints and connections. Use a high-quality roofing sealant designed for your roof material, and make sure everything is sealed properly.
How to Maintain Your Roof Drain
Your roof drains require TLC just like any part of your home. Here’s what to do:
- Clear debris regularly. Leaves and twigs can build up in your roof drains and block the water.
- Check your roof for cracks or rust and any other signs of wear. Repair it quickly to prevent further issues – especially after heavy rain.
- Check the seals to make sure all the drains and downspouts are intact, as sealants can wear down every few years.
- Make sure your downspouts and roof drains are properly sloped. If water doesn’t have a clear path to flow away from the roof, it could start to pool – which is bad for your roof’s structural integrity!
Installing and Fixing Roof Drains
You should be a confident DIY master now! A well-maintained roof drain will keep your roof healthy and your home safe. Take care of your roof with proper installation and maintenance to ensure they keep you dry for years to come.
FAQs
What Kind of Pipe Is Used for Roof Drains?
PVC or cast iron pipes are the go-to materials for most drains. PVC is a lightweight and durable option – and it’s resistant to corrosion. Cast iron is stronger and more durable, which is best for larger, commercial building roofs.
How Do You Clear a Clogged Roof Drain?
Start by removing any visible debris, like twigs and leaves, and if you face deeper blockages, use a plumber’s snake or high-pressure water hose. It might be worth calling a professional if the clog is too stubborn.
