Roof styles often include gable and studio designs. The solid roof features insulated laminated roof panels with a unique foam core of various thicknesses. This roof core is a great insulator against the outside elements. Then, if you’d like we can add skylights, ceiling fans, lighting and more.

All construction materials are available in a variety of colors as well as your choice of textures to complement your home.

We also offer wide selection door and windows, sized to fit and work together with the selected wall panels. Choice of windows are typically sliding glass, acrylic, vinyl pane vertical or horizontal windows. All our windows with tempered safety glass and easy to operate.

Northwest Uses Only the Highest Quality Products


We use insulated laminated roof panels that snap together tightly, forming a strong, structurally sound roof as well as a weatherproof barrier protecting your patio from the elements.


Typically, we use products by Four Seasons or Duralum because we know we can count on their products perform best, especially if giving your outdoor space extra amenities. All products used are virtually maintenance free, never rust, warp, crack, rot or become infested with insects. Components retain the original color, gloss and texture longer and better than patio products made of alternate materials. Plus we and our manufactures stand behind our products with a transferrable Lifetime Warranty.
