Furthermore, it can attract rodents and insects into your attic and lead to animal-related damage and bacterial growth.<\/li>\n<\/ol>\n\n\n\n<ol start=\"2\">\n<li>The second reason is that lint will build up in the soffit, walls, or attic, which poses a severe fire hazard for the home.&nbsp;<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">Benefits of Venting a Dryer Through a Soffit<\/h2>\n\n\n\n<p>Although less common than roof venting, there are several benefits of venting a dryer through a soffit.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Minimized Effects of Wind and Weather<\/h3>\n\n\n\n<p>Installing the terminal vent of a dryer exhaust in the soffit means that the vent has a unique angle on the underside of the rooftop. Wind seldom flows strongly at this angle, thus very little wind-related backdraft is possible. <\/p>\n\n\n\n<p>The vent will also be less likely to cause leaks in your house because of its sheltered position in the eaves (when was the last time you saw rain being directed upwards!).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">No Need for Hole Through Your Roof<\/h3>\n\n\n\n<p>By installing a dryer vent through a soffit, you do not need to create a new hole through your roof. If your roof is already housing your attic vents, bathroom exhaust vents, plumbing vents, etc., then the dryer vent may overcrowd your rooftop. <\/p>\n\n\n\n<p>Furthermore, using a soffit vent helps to keeps your house leak-free because every time you make a new hole in your roof, there is a certain degree of compromise to the weatherproofing and you naturally increase the risk of leaks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">May Be the Shortest Route<\/h3>\n\n\n\n<p>If your dryer is not located in an upper-floor bedroom, then running the dryer ducting to the soffit is a shorter route compared to running it to the roof. Since the shorter the route, the better, this should factor into your decision.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"563\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/10\/20_Dryer-Venting-Exhaust-Dos-and-Donts_Benefits-Drawbacks_v1.1-min.jpg\" alt=\"\" class=\"wp-image-4820\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/10\/20_Dryer-Venting-Exhaust-Dos-and-Donts_Benefits-Drawbacks_v1.1-min.jpg 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2021\/10\/20_Dryer-Venting-Exhaust-Dos-and-Donts_Benefits-Drawbacks_v1.1-min-300x169.jpg 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2021\/10\/20_Dryer-Venting-Exhaust-Dos-and-Donts_Benefits-Drawbacks_v1.1-min-768x432.jpg 768w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"563\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/10\/20_Dryer-Venting-Exhaust-Dos-and-Donts_Benefits-Drawbacks_v1.1-min.jpg.webp\" alt=\"\" class=\"wp-image-4820 lazyload\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/10\/20_Dryer-Venting-Exhaust-Dos-and-Donts_Benefits-Drawbacks_v1.1-min.jpg.webp 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2021\/10\/20_Dryer-Venting-Exhaust-Dos-and-Donts_Benefits-Drawbacks_v1.1-min-300x169.jpg.webp 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2021\/10\/20_Dryer-Venting-Exhaust-Dos-and-Donts_Benefits-Drawbacks_v1.1-min-768x432.jpg.webp 768w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/10\/20_Dryer-Venting-Exhaust-Dos-and-Donts_Benefits-Drawbacks_v1.1-min.jpg\" id=\"mv-trellis-img-2\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Drawbacks of Venting a Dryer Through a Soffit<\/h2>\n\n\n\n<p>There are also several drawbacks of venting a dryer through a soffit. These disadvantages are:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Short and Straight Requirements<\/h3>\n\n\n\n<p>To operate efficiently, dryer ventilation systems should be as short and as straight as possible. This will, unfortunately, dictate where the ventilation exit can be located. <\/p>\n\n\n\n<p>For dryers in basements or other below-ground locations, the best location for the vent would be at or near ground level, which is not near the soffit, so it is not a viable option.<\/p>\n\n\n\n<p>If the dryer is located in a central room, you will have to assess the route to the soffit; if it involves too many turns, then it might exceed the allowable ducting length for dryers, which we discuss later on in this article.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Backdrafting<\/h3>\n\n\n\n<p>Another drawback of venting a dryer through a soffit is that the exhausted air is warm and naturally wants to rise.<\/p>\n\n\n\n<p>So, a backdraft damper is required to prevent the hot air released from the vent from entering the ducts again.<\/p>\n\n\n\n<p>Backdraft dampers are a requirement anyway, so this is not an unnecessary addition. However, it does make backdraft damper failure more problematic.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Soffits on Upper Stories Lack Accessibility<\/h3>\n\n\n\n<p>Another drawback of venting a dryer through a soffit is that the soffit dryer exit is more difficult to clean regularly if they are on the soffits of upper stories as the vent will only be accessible with a ladder. <\/p>\n\n\n\n<p>However, it is vital that the vent be cleaned regularly in order to prevent lint buildup and outside debris (including animals and nests) from collecting onto the exit. Such a buildup creates a significant fire risk. <\/p>\n\n\n\n<p>Furthermore, the debris buildup can cause decreased efficiency and reduced speed of airflow. <\/p>\n\n\n\n<p>Since these soffit vents are out of sight, they are more likely to be forgotten by the homeowner and not maintained.<\/p>\n\n\n\n<p><strong>It is important to note that soffit vents are considered to be more accessible than roof vents as<\/strong> <strong>long as they are not on the soffits of upper stories.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">All Normal Installation Regulations Still Apply<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Manufacturer Instructions Take Precedence<\/h3>\n\n\n\n<p>As I mentioned previously, IRC <a rel=\"noopener\" data-lasso-id=\"2105\" href=\"https:\/\/codes.iccsafe.org\/content\/IRC2021P1\/chapter-15-exhaust-systems#IRC2021P1_Pt05_Ch15_SecM1502.3\" target=\"_blank\">Section M1502.3<\/a> says that dryers should be installed and vented according to the manufacturer&rsquo;s instructions.<\/p>\n\n\n\n<p>Each clothes dryer is designed to be vented a certain distance, withstand particular conditions, and operate in a specific manner. Thus, it is important to understand that the dryer manufacturer&rsquo;s instruction manual takes precedence in terms of installation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Dryer Vent Opening Dimensions<\/h3>\n\n\n\n<p>According to the IRC <a rel=\"noopener\" data-lasso-id=\"2106\" href=\"https:\/\/codes.iccsafe.org\/content\/IRC2021P1\/chapter-15-exhaust-systems#IRC2021P1_Pt05_Ch15_SecM1502.3.1\" target=\"_blank\">Section M1502.3.1<\/a>, the total open area of the dryer exit must be at least 12.5 square inches (8065 mm<sup>2<\/sup>). This is to ensure that the vent actually allows adequate air exhaustion and ensure proper ventilation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Correct Ducting Material and Size<\/h3>\n\n\n\n<p>Dryer vents require specific ducting material and a complimentary duct size so that there is a tight fit and no leakage.<\/p>\n\n\n\n<p>Both the material and size required to make ducting a successful addendum to soffit dryer ventilation vary based on the dryer and soffit system. <\/p>\n\n\n\n<p>However, the IRC does stipulate three non-negotiable rules in <a rel=\"noopener\" data-lasso-id=\"2107\" href=\"https:\/\/codes.iccsafe.org\/content\/IRC2021P1\/chapter-15-exhaust-systems#IRC2021P1_Pt05_Ch15_SecM1502.4.1\" target=\"_blank\">Section M1504.1<\/a>:<\/p>\n\n\n\n<ol>\n<li>Venting ducts require a <strong>smooth interior finish<\/strong>.

A dryer vent and another ventilation system often have different protocols. For example, dryer ducts cannot use the popular flexi duct that is often used for fans because dryers have stricter cleaning rules for regularity. <\/p>\n\n\n\n<p>Thus, if a dryer vent and another ventilation system were combined, there would be material incompatibility because the same type of ducts cannot be used for both ventilation systems and this becomes inefficient to operate.<\/p>\n\n\n\n<p>But more importantly, this rule exists because there are significant dangers associated with combining a dryer vent with another exhaust system, such as a bathroom fan. For more information, read through my article on <a data-lasso-id=\"2109\" href=\"https:\/\/thetibble.com\/can-bathroom-fan-and-dryer-share-a-vent\/\">Can Bathroom Fan and Dryer Share a Vent<\/a>.<\/p>\n\n\n\n<p>However, the rule extends to <a href=\"https:\/\/thetibble.com\/multiple-dryers-share-same-duct\/\" data-type=\"post\" data-id=\"20557\">two dryers sharing a vent<\/a>.

This information is found in <a rel=\"noreferrer noopener\" href=\"https:\/\/codes.iccsafe.org\/content\/IRC2021P1\/chapter-15-exhaust-systems#IRC2021P1_Pt05_Ch15_SecM1502.4.2\" target=\"_blank\">Section M1502.4.2<\/a>.<\/p>\n\n\n\n<p>It&rsquo;s a lot of information in a single paragraph, so instead of quoting it, I will break it down for you with the reasons why (which I always find helpful).<\/p>\n\n\n\n<p>You have to <strong>support the ducts at intervals and these supports must be added every 12 feet<\/strong> (at least). Supporting the ducts helps to prevent sagging.<\/p>\n\n\n\n<p>The choice of minimum 12 feet intervals is not arbitrary. While they do not state this in the IRC, you can assume that they did some testing and found intervals over 12 feet resulted in significant sagging with common ducting materials.<\/p>\n\n\n\n<p>Sagging is quite a nightmare for exhaust systems. It causes pooling of moisture, collection of lint, and just generally interferes with the efficiency of airflow through the duct.<\/p>\n\n\n\n<p>The supports also reduce stress on the ductwork, minimizing the risk of breakages over time.<\/p>\n\n\n\n<p>Ducts have an insert end and an end into which the insert end of another length of duct fits. The IRC specifies that the <strong>inserting end must face the direction of airflow<\/strong>.<\/p>\n\n\n\n<p>While the lip of the insert is very slight, it has the ability to impact airflow (creating turbulence, which slows the air down) and it can trap lint (flammable), which is why this stipulation was included.<\/p>\n\n\n\n<p>Sliding the ducts together is not sufficient. The IRC requires the <strong>ducts to be secured together and in place<\/strong>.<\/p>\n\n\n\n<p><strong>Fasteners must be mechanical<\/strong> (i.e., screws or something similar and appropriate). They <strong>must not protrude into the interior<\/strong> of the ducts more than 1\/8 inches.

These are designed to allow air to flow through the exhaust duct to the outside but prevents the outside air (and the exhausted air) from flowing back into the ducts.<\/p>\n\n\n\n<p>This is particularly important for dryers that vent through the soffit because the air is exhausted down as opposed to up (like through a roof vent).<\/p>\n\n\n\n<p>It is essential to understand the direction of airflow before you purchase your damper. Gravity dampers only operate with an upward or horizontal airflow and will not operate with a downward airflow, which is what we get with soffit vent terminations. <\/p>\n\n\n\n<p class=\"has-central-palette-1-background-color has-background\"><strong>I recommend AC infinity backdraft dampers. Try to avoid the cheap plastic ones. They are usually not rubber-sealed nor spring-loaded.
