Shelter Systems’ Portable RoofShell ™ Roof Structures

Shelter Systems’ Portable RoofShell ™ Roof Structures are thin sections of spheres or tunnels made from a lightweight, strong, waterproof, ripstop film which is either white, translucent or black on the inside/white on the outside. They are great for using as rain and sun porches by tying them to buildings, poles or trees with the attached clips, as quick shed roofs, or anywhere you want a low arched roof covering. Other uses for Shelter Systems’ Shells and Tops include pool coversspa covers, and fish and Koi pond covers.

We offer three types of Roof Structures: RoofTops, RoofShells, and PorchShells. The RoofTops are the top portion of Domes. The RoofShell has a flatter curve. The PorchShell works well for square roofs or porches.

Easy set up

Even our largest Roof Covers can be set up in less than 30 minutes without tools. Insert the interchangeable poles into factory-attached connectors spaced evenly over the cover. The poles bend slightly when inserted, tightening the cover into a wind- and waterproof shelter. The cover is freestanding, requiring no guy lines and can be moved into the desired position or location without disassembly. The cover can be taken down in 5 minutes: just remove the poles and roll up the covering. See the RoofShell™ Manual here.

Easy Access

Shelter Systems’ Roof Covers are free standing and light weight. If you desire you can easily unhook the covering from it’s anchor points to move it around or lift it off.

Sturdy design

Shelter Systems’ Roof Covers are stronger than any other structure made of the same materials. Because of its curved shape with no corners, there are no weak points. Our patented structure is drum tight, waterproof and wind-resistant. Shelter Systems’ Roof Covers have the poles on the outside with the covering suspended under the frame via Shelter Systems’ own Grip Clips™ tarp fasteners, such that the frame and the covering are not in direct contact. Because the covering is under constant and even tension, the tent will not flap or shred in high wind, poles cannot rub against the covering, which would eventually wear holes in it, and water and leaf debris cannot get caught in dips between poles. The shingled panels of our Roof Covers overlap each other by 6″, making the structure very strong and completely leak proof (we have a leak-proof guarantee for all of our shelters). The shingling design allows the structure to breathe for excellent air circulation and so moisture is driven out by vapor pressure, preventing condensation. Shelter Systems’ patented Grip Clips™ tarp fasteners are used to join the cover material to the pole frame and to fasten the shingled panels together. Grip Clips remove the need for sewn seams or grommets that puncture the cover, which would allow rain to enter.

Durable materials

Shelter Systems’ Roof Covers have a covering made wholly of a superstrong, tear-proof, white multilaminate woven ripstop film which will not rot or mildew. The fabric is a super strong, high tensile strength, rip-stop, completely waterproof, mildew resistant, and cannot be torn by hand even after it is cut. This US made, proprietary material is the finest material we could find to make our tents from.

The Poles are of high quality US made PVC that is admirable for its strength, resiliency, long life, natural UV stability for a long sun life, and its strength to weight and cost ratio. The poles we use are Class 200 PVC tubing.

Shelter Systems’ Patented Grip Clips that we use to join the cover material to its poles are molded of a UV stabilized resin blended specifically for it high strength and durability.


Shelter Systems Roof Covers are reliable and affordable. Our waterproof design does not require a rain fly and the particular geometric shape utilizes material efficiently. The high performance covering is affordable and the design and tarp fasteners used mean our tents are labor efficient to build.
