How to install gutters on angled fascia? With wedges!

Sometimes, the things that look the best have some complicated means to get to that state. When it comes to engineering, that is especially true. Sometimes, there are some extreme measures needed to make a project work

But, also sometimes, simple solutions can kick it out of the park. Like most things in life, there are some solutions that come from simple facts. For instance, having something hanging around an angled surface can be supported with many things, including wedges.

Today’s topic is all about angled fascia on roofs that, while they can look pretty good, are a headache when it comes to installing gutters. So, how to install gutters on angled fascia? Can I use something as simple as a wedge in between to level thing out? Let’s see if that is the case in this situation and what you need to do.

Can you install gutters without wedges?

First up, let’s find out if you can install gutters without wedges. You may be wondering why you can’t just install the gutters directly at those angled fasciae without any repercussion. The thing is though, are you really sure you have saw something like that before?

The answer is definitely no. You can’t install those gutters in an angled fascia where, filled with water, leaves and debris; they can’t achieve their goal at all when they are dripping all over your patio. Also, those may look really weird!

But if you put some wedges in between the angles and the gutters, and reinforce the structure with some hangers, you may have now the perfect looking gutter you want that can route the water the way is supposed to. Or that is the theory.

So, how to install gutters on angled fascia then? Is it possible that a combination between wedges and hangers would be all you need to avoid a mess in your roof and patio?

How to install wedges on angled fascia?

Before we go into how to install gutters on angled fascia, we need to take a look at the part that can make this trick actually work. We are of course talking about wedges in between the roof and the gutters and so, how to install wedges on angled fascia?

The idea of having a wedge in between those pieces is to get the gutters as leveled as possible. It is to keep the water inside the gutters where it should, and to avoid a bad-looking thing that hangs in your otherwise beauty of a roof. 

To do this, you would need to insert the gutter shims (the wedges) between the gutter and the roof slope. You also would need to cut these pieces to a degree that makes the gutter to be as leveled as it can be; for the reasons mentioned above.

When nailing the shims, be careful if you have shingles in your roof. It is a bad idea to nail them through because it can cause a leak. Of course, leaks are bad for your home. The best option is to lift them, especially the asphalt ones. Then, tighten this setup under them. 

But this mentioned setup is not complete at all without something that can support the weight of the gutters being loaded with water, leaves and many other things that can land on them. In fact, not having these hangers can lead to a gutter falling in the middle of the rain; this can potentially damage the roof.

How to install hangers on angled fascia?

The first part on how to install gutters on angled fascia is done by inserting the wedges in between the gutter and the roof support part (under the shingles or in a sturdy area of it that can’t produce a leak). But, that is not all. You would need to support the weight of said structure with something else. After all, nature is unpredictable. How to install hangers on angled fascia?

First up, you would need to choose a variety of gutter hangers that can support the weight of the entire thing. Just imagine a thunderstorm for many, many minutes. A flexible hanger can’t possibly support the amount of water that mother nature can drop all over your roof. So instead, go for the one that is made to sustain a lot.

Those are made mostly of sturdy metal or plastic rods (although metal looks like the better bet); they would need to be secured to the wedges that are behind of the gutter. To achieve that objective, the nails or screws you use need to be long enough to get to the roof, without popping out of it. Some say 2 inches is a safe approach from the wedge to the roof.

You could also go for kits that have everything you need to do a complete installation of the gutters to the roof. They would not explicitly tell you that is intended for angled fascia roof; but, you can buy them and also get the wedges that are designed for this kind of job. There are many manufacturers around the world that have these materials.


While it may look rather difficult to do, the how to install gutters on angled fascia job should not be as hard as you may think when you consider that simple wedges can solve your problem that easily.

When installing a wedge in between a gutter and your angled fascia roof, the idea is to give the gutter a support where to rest in a perfectly (or almost perfectly) leveled way. This is to allow water to flow without any resistance and without spilling all out of the gutter.

But apart from just nailing or screwing a gutter with a wedge behind, you should also add hangers to support the weight of the entire structure. These hangers can be found in a variety of materials; mostly plastic and metal, that can work for different circumstances. In the case of an angled fascia, your safest best is to go metal.
