General Under Deck Drainage FAQs

How Can I Keep The Area Under My Deck Dry?

You can create a dry, usable space underneath your deck by installing an under deck drainage system and/or a deck ceiling. Any deck drainage system (sometimes called an “underdeck drainage system” or “underdecking”) will divert rainwater away from the space under your deck. Some deck drainage systems include a deck ceiling, which looks like a clean, finished roof that installs to the underside of your deck joists.

Do I Need A Drainage System Under My Deck?

Under deck drainage isn’t typically required by building codes, but it does make your outdoor living space significantly more useful in a few ways. First, creating a dry space underneath your deck effectively doubles your deck space, allowing you to use an underdeck space that is often wasted. Under deck drainage also protects your deck frame from water damage by diverting water away. Deck ceiling is a beautiful stylistic choice, and a dry underdeck space also allows you more options to furnish your space with furniture and decorations that need some protection from rain and sun. Beyond that, having a dry space under your deck is great for storing grills, smokers, chairs, tables, or any other objects to protect them from rain.


Choosing Your Under Deck Drainage

What’s the Difference Between Under Deck Drainage Systems?

The biggest difference in our Under Deck Drainage offerings is when you can install them. Trex RainEscape is a drainage system that doesn’t include a deck ceiling - you can choose the deck ceiling look of your choice. RainEscape also must be installed when you’re putting decking on your deck, so it’s a great choice to install with a brand new deck.

ZipUP UnderDeck Drainage and UpSide Deck Ceiling by Color Guard are both drainage systems that include a beautiful finished deck ceiling look for your outdoor living space - and both can be installed on existing decks without having to uninstall deck boards.

How Do I Know How Much Under Deck Ceiling I Need?

We’ve created a handy ZipUP Calculator tool - just input the dimensions of your deck, and the calculator will tell you how much of each ZipUP UnderDeck Drainage component you’ll need, including a live-updating cost estimate.

Under Deck Drainage Maintenance

How Do I Clean Under Deck Ceiling?

It’s easy to clean your under deck drainage system and deck ceilings. The visible surfaces wipe down easily with a broom and a soapy rag. You can check for clogs in your drainage by pouring a few cups of clean water onto your deck and watching to see if it flows out into your gutters. If it doesn’t, figure out where the clog is, remove a panel from your deck ceiling, and remove it.
