Sunroom with a Patio - Room Additions

Patio Room

The difference of a patio room from a sunroom is that patios have a three-inch R-23 insulated solid roof, unlike the glass roof of the sunroom. Patio rooms can be made into a:

• Garden Room
• Entertainment Area
• Play Area
• Home Office
• Exercise Room


Patio Covers

Covers can be made using solid aluminum or lattice. Lattices are flaps where rain and sunshine can go through. The patio covers come in custom sizes and are available in six different colors. All materials have a lifetime factory warranty.

Durability of Patio Covers

Our patio covers are maintenance-free and provide the best shade. They won't burn and won't be a breeding ground for termites. The patio does not need repainting, and won't warp, rot, or peel.


The process for patio installation is the same as the process for installing a sunroom. First, you have to tell us what you want us to construct: a patio enclosure, patio cover, or a sunroom. Next, we will go over the product setup and perform an in-home estimate. You can visit our showroom for design ideas.

In-Home Design

The design process starts with an in-home design appointment where our design team shows you pictures, brochures, engineering plans, and product samples. We will then build a 2D and 3D design model and provide you a price and turnaround time estimate.


After the design phase, we'll have our contract signing and let our construction managers do a site check. We'll order and build your patio in the factory and set up a date for installation.
