On a hot day, your upper deck surface can reach a blistering 140 degrees, creating a stifling heat trap. But you don't have to retreat indoors to stay cool.

Discover the "Canopy Effect" and learn how the right underdeck system can actually drop your outdoor temperature by up to 15 degrees.

Read our latest article to see the science behind underdeck cooling:

Why Your Upper Deck is a Heat Trap On a 90-degree day, a wood or composite deck surface can reach temperatures of 140 degrees Fahrenheit. This creates a “convection dome” that makes the air above the deck stifling. Homeowners often find themselves trapped inside, looking at a beautiful backyard ...

Ever wonder how a RainTight Underdeck System actually works? It’s all about smart engineering! If you want to know how we keep your outdoor living room completely dry during a downpour, here is the step-by-step breakdown:

1. The Downpour: Rain falls from above, draining naturally between your existing deck slots.
2. The Catch: Our custom RainTight ceiling panels capture that water before it ever reaches your patio and channel it away.
3. The Redirect: The water is seamlessly directed by our integrated gutters straight to the downspouts.
4. The Result: The rain is drained completely away from your deck and foundation, keeping the area underneath perfectly dry, safe, and comfortable!

A RainTight Underdeck System doesn't just manage water—it provides the architectural foundation to completely transform the space beneath your deck. By diverting deck-drip and debris, we create a dry, protected "shadow box" environment perfect for high-end appliances, electronics, and comfortable furniture.
