Opposed to the traditional practices of venting a bathroom fan through a side wall or roof, you can also vent it through a soffit, which is much preferable in some cases, as we will see in this article.
If you are also amongst the people who are interested in avoiding making a hole in the roof and get the deed done using a soffit, you have come to the right place.
Here, I will be guiding you in a detailed step-by-step guide on how to achieve it.
So, let’s get started right away:
What Is A Soffit?
In case you are wondering, a soffit is essentially the underside portion of the roof eave, and is mostly used when installing the fan is preferable to the roof or due to some reason, you don’t want to make a hole in your ceiling.
Now there are a lot of reasons why drilling your roof might not be a good idea.
For one, it may cause a leakage problem shortly, or there may be a second story in the house, which makes it even bigger problem, which is to vent it out to the side wall eventually.
Not only is this method expensive, but it also requires a significantly higher level of work.
Therefore, whether it is the first scenario or the second, installing a soffit instead is probably the easiest solution to the problem. Now, let’s continue how to install it:
How To Install A Soffit Vent Cover
I will guide you in a detailed step-by-step manner, so make sure you go through all the steps to ensure proper installation and don’t skip any of the steps mentioned.
- Make Sure You Avoid Dips In Hose
First and foremost, to ensure that you don’t face any problems with the soffit, later on, make sure there are no dips in the hose when you install the soffit exhaust vent cover.
Please ensure the frequency of bends it faces or the number of times it turns is as low as possible. The major problem it causes after installation is the accumulation of water inside it.
The parts which are at a lower level than others naturally retain water inside them, which in turn creates many problems.
- Vent Hose Size
If you are not already aware of the duct size of the bathroom, make sure to measure it again and get the duct exactly of that size.
However, in most cases, you will just be replacing a previously installed duct, so you may want to skip this step as the size installed previously will do just fine.
If you don’t know the duct size of your bathroom, here are some clues. An older bathroom will likely have duct sizes of 3-inch while if your bathroom is recently built, the size will most probably be 4-inch by 6-inch or such.
However, I still recommend you measure it again to make sure.
- Cutting The Hole For Soffit
Now comes the real part, making the space available for installing the soffit.
First off, you need to ensure that the hole you cut for soffit is at the right place, as you cannot cut a hole blindly, anywhere you want.
Make sure that the location you choose for cutting the hole is between the roof lookouts. Find the location first and mark it using a marker or something, as to avoid missing the spot even with an inch.
Next, cutting the hole is also not that simple. When you buy a soffit, it will usually accompany a template according to which you will cut the hole.
Draw this template on the location you previously marked, again with a marker so you can follow these marks afterward while actually cutting the area.
Next, follow the marks you have made and cut the area necessary to install the soffit there. You can use any cutting tools you are comfortable with.
If you haven’t used on before, I suggest you go with tin snips.
- Placing The Vent Hose
Just where you cut the area, there has to be a corresponding hose in the attic installed so you can connect it to the soffit after installing it.
So, as the fourth step, install the vent hose so we can continue installing the soffit.
- Pulling Out Vent Hose From The Hole
It would help if you pulled the vent hose from the attic, using the hole you cut in step 3.
Make sure you pull it out to an appropriate length as to easily connect it to the soffit. If you don’t know the length appropriate, a foot will be enough for most of the cases.
When you’re done pulling the hose, make sure you cut the remaining part of the vent hose; otherwise, the vent hose may experience bending, which we need to avoid, as I mentioned in the first step.
- Connecting The Vent Hose And Soffit Cover
Now comes the final step, take a metal clamp, and use it to securely tighten the vent hose and the soffit cover together.
Use a tool to fasten the screw and don’t just do it by hand, or it will come off easily.
When the screw is fully tightened, you can cover it with a foil or something to make sure it doesn’t fall apart.
Now, connect the vent cover on the soffit using a drill, if the hole is not already there. If there are holes made already, tighten the screws using a screwdriver.
So, we have seen a step-by-step guide on how to easily install a soffit cover inside a bathroom for ventilation purposes.
The guide contains complete steps that you need to follow, without needing the help of any professional or other external help.
Moreover, I have also mentioned the things you need to avoid so that you may get the best results.
However, make sure to go through all the steps in detail; otherwise, you may miss some important points.
