RainTight Decks gives a low profile, streamlined finish that creates a ceiling below the joists of your deck. Our panels and gutters are all seamless, smooth-finished aluminum that is virtually maintenance free and last a lifetime. RainTight Decks have been carefully designed to provide the BEST system for underdeck protection. Our rigid, heavy gauge aluminum will hold up to any amount of rain or snow….GUARANTEED!

Make the Most of Your Outdoor Living Space with RainTight

The weather in the Midwest and Southeast can fluctuate often, sometimes from one day to another. Even when the weather is pleasant enough to enjoy the outdoors, blazing sun, rain, and strong winds can send you running for indoor shelter. And if you don’t have those factors keeping you in, the annoying insects and pests will.

RainTight has unique solutions that allow you to enjoy your existing deck, patio or porch without the negative side effects. We can build on your current outdoor structures that provide shelter and shield you from the weather and pests that invade your space.

Order our Kits or Become a Dealer!


We seal the floor of your above-ground deck and install a “ceiling” beneath it to make the space below it more usable. We even offer kits you can order for DIY-ers.

patio covers

Our permanent patio covers will protect you from rain and the sun’s rays when you sit outdoors. We can easily convert the cover to a fully enclosed space down the road, if desired.

screen enclosures

We install a screened enclosure around your existing patio, deck or porch, then attach a permanent roof over it for additional protection.


Long-Lasting Quality and Durability

Our outdoor enclosures are all made of high-quality aluminum. We don’t use other materials like vinyl or wood because they don’t provide the same strength and durability. Our ceilings and patio covers are lightweight, yet strong enough to mount a ceiling fan or light fixtures. The covers will withstand any amount of rain or snow without bowing or cracking.

Our enclosures are made to last and require very little maintenance. They are rust-proof and resist fading. They are available in several colors to complement your existing décor. The colors are baked-in, not painted on, resulting in long-lasting beauty that doesn’t chip or flake.

Affordable and Convenient

Unlike new construction, RainTight’s solutions are much less expensive because we build on structures you already have in place. That means no digging, pouring concrete, or people trudging through your yard and home. No need to uproot trees or vegetation or rearrange your landscaping. You’ll get your beautiful outdoor enclosure within 4-6 weeks, as opposed to waiting months for a brand-new one built from scratch.

We should have done this years ago. We put in a new deck and tried to do the under decking ourselves. But we failed miserably. We looked into other under decking companies, but none of them gave us what we wanted/needed. They were friendly, professional, and cleaned up after themselves. The under decking looks fantastic. We have our space back, and can finally leave out our TV and cushions without them getting destroyed. Thanks RainTight…..


We had a great experience with them from sales call to install. So far the system is working great and looks wonderful! Thanks!


I had them put a ceiling on my 32 foot by 12 foot deck. The ceiling was installed in one day. The very next day it rained all day and sometimes pretty heavy. However, the ceiling did not leak anywhere. I felt the quality and look of the work was outstanding and we got everything we wanted from this project.


We did the rain tight ceiling under our large deck and a screened porch underneath. The product is high quality and the installation was professional. If you want to expand your outdoor living area and add value to your property, we believe this is an excellent solution.
