How to Install Gutters on a Metal Roof

If you’re getting a metal roof, you’re already aware of its durability. But to keep it strong for years, you need the right support systems in place. Gutters are key because they keep water from pooling on your roof.

Now, when putting gutters on a metal roof, you need to think about a few things. And while it might seem hard, with the right tools and help, you can do it right. This article will discuss the benefits of using gutters. You will also learn the simplest ways to install gutters on a metal roof.

Advantages of putting gutters on a metal roof

Installing gutters on your metal roof is a smart choice that brings many benefits. Gutters help to guide rainwater and melted snow away from your roof and the foundation of your home. Without gutters, this water can cause damage by seeping into the soil around your home’s foundation. Gutters catch the water and send it through downspouts, directing it several feet away from your house, and keeping your foundation safe.

Gutters prevent foundation damage

Gutters are more than just a shield against stains on your home; they also help protect its foundation from water damage. By directing rainwater away from the building, gutters prevent too much moisture from gathering around the foundation. This lowers the chances of cracks, erosion, and structural problems caused by water getting into the foundation.

Thus, having good gutters doesn’t just keep your home looking nice, but it also keeps it strong and safe, saving you from having to pay for expensive repairs later on.

Gutters increase roof longevity

Having gutters is beneficial for extending the life of your metal roof. Without gutters, when rain falls, it carries tiny particles that can scratch and stain the roof over time. Gutters stop this by directing debris away from the roof panels and seams, keeping them safe from harm.

With gutters, your roof will stay looking smooth and strong for a longer time, which means less need for frequent repairs or replacements.

Gutters protect your landscaping

Gutters on your metal roof are essential for protecting your landscaping from water and soil erosion. Without gutters, water flowing off the roof can harm your lawn, gardens, and wash away mulch. Gutters catch the water when it’s still gentle and not powerful enough to cause damage. This helps your flower beds, bushes, and garden beds to stay healthy and thrive.

Gutters prevent ice dams

In colder places, gutters are really important for stopping ice dams when snow and ice pile up on the roof. Without gutters, when snow suddenly melts, the water doesn’t have anywhere to go. It can get under the shingles and freeze again, making ice dams. These dams can lead to leaks in your attic and walls. Gutters help get rid of the melted snow and ice, so they don’t freeze again and harm the building.

Gutters reduce maintenance costs

Gutters direct rainwater away from the walls and prevent dirt, debris, and moisture from accumulating and causing unsightly stains over time. This helps to keep the home looking clean and well-maintained without the need for frequent cleaning.

As a result, gutters not only enhance the appearance of your property but also save you money by reducing the amount of maintenance required to keep it in good condition.

What types of gutters work well on metal roofs?

When choosing gutters for your metal roof, consider what will fit best with the metal material and the weather in your area. I suggest you contact your local roofers or contractors first. They can help you with better options, proper plans, costs, and strategies. To find additional ideas, you can click here.

However, here are some options that will be good with metal roofs:

  • Snap-Lock Gutters: Snap-lock gutters are commonly used with metal roofs. These gutters are designed to easily snap onto metal roof panels, making a strong and leak-proof connection. They give a neat look and handle water flow well.
  • Fascia Gutters: Fascia gutters are fitted onto the fascia board, the horizontal board beneath the roof’s edge. These gutters blend well with the roof’s design and efficiently drain water, making them a great option for metal roofs.
  • Seamless Gutters: Seamless gutters, typically made from aluminum or steel, are a top choice for metal roofs. These gutters are custom-made to fit your home’s dimensions precisely, ensuring a seamless installation. With no seams or joints, the risk of leaks is greatly reduced, offering both functionality and aesthetics.

How to install gutters on metal roofs

Maintaining gutters might not be a top priority, but it’s necessary to keep your home in good shape. Whether you’re replacing old gutters or installing new ones, follow the steps below:

Before You Begin:

  • Cut the gutter to the correct length for each section and ensure there’s at least a 100mm overlap at joints.
  • Apply roof and gutter sealant along the overlap, and secure the gutter with rivets, sealing around them to prevent leaks.

Attaching Stop-Ends:

  • Position stop-ends and pre-drill holes for rivets.
  • Apply sealant along the overlap, position the stop-end, and secure it with rivets.

Assembling the Spout:

  • Mark the center of the outlet on the gutter and cut out a hole for the spout.
  • Apply sealant around the opening, place the spout, and secure it with rivets.

Preparing for a Mitre:

  • Measure and mark mitered corners accurately.
  • Remember, internal miters have shorter face sides, while external miters have longer face sides.

Hanging the Gutter:

  • Set the required fall of the gutter using nails and a stringline.
  • Place brackets along the stringline at a maximum of 1200mm intervals and secure them with screws.
  • Use suspension clips if needed for desired fall.

Adding Downpipes:

  • Install a downpipe offset for buildings with eaves.
  • Use a plumb line to mark the position of the downpipe and measure for the lower offset.
  • Connect downpipe sections and secure them to the wall with brackets and anchors.

The common problems with gutters on metal roof

If you have a metal roof, there are some extra things to consider when installing gutters. Metal roofs can be slippery, so it’s important to securely fasten the gutters to prevent slipping.

Also, because metal roofs expand and contract with temperature changes, there might be issues that arise over time, even if the gutters are installed perfectly. So, it’s essential to take these factors into account to ensure the gutter installation goes smoothly and lasts a long time.

Fastener Issues

Sometimes, gutters on metal roofs can leak if the fasteners get loose or the gutters bend from granules falling off. To stop leaks, you can use roofing cement, silicone sealant, or butyl tape under the screws. It’s better to screw the gutters directly into the roof instead of nailing them horizontally. Stainless steel screws are the best choice for durability and to avoid rusting when putting gutters on metal roofs.

Problems from expansion and contraction

Metal roofs can expand and contract because of daily temperature changes. This movement can be a problem for gutters and might cause leaks over time. To stop this, you need to let the roof breathe by using hangers to support both sides of the gutter. When you’re securing gutters, make sure to leave some small gaps for flexibility. These gaps can be filled with caulk to prevent leaks while still letting the roof move a bit.

Condensation growth

Sometimes, condensation builds up between the metal roof and gutters because of temperature differences. This can cause water to drip from the gutters. To stop this, you should put in gutters with a slope of at least 1 inch for every 10 feet. This way, water can drain properly.

Wider gutters, like ones that are 6 inches wide, can hold more water. Also, using a weather-resistant sealant to seal the edge of the gutter and around screws or rivets can block airflow into the gutter. This helps to balance out temperature changes that might lead to condensation.

Wrap Up

Making sure your metal roof stays sturdy for a long time means putting in the right gutters. These gutters are really important because they keep water away from your roof, which stops your home from getting damaged and keeps it strong.

Even though putting up gutters might seem tricky, if you have the right tools and help, you can get it done well. So, by making sure your gutters are set up right, you’ll have a metal roof that lasts and keeps your home safe for years to come.

Happy roofing!
