Standard Hipped Roof

At Shelter Works, we outfit most shelters with hipped roofs for the following reasons.

  • Stability - The inward slope on all four sides provides an added level of sturdiness and durability.
  • Funnels Precipitation Away - Not only does it funnel water away in every direction, but the design is excellent for areas that experience heavy snow loads. Snow naturally moves downward and away from the structure.
  • Wind Resistance - The gentle slope reduces issues with uplift making them ideal for areas price to hurricanes or other high winds.
Fire Rated Roof on Fiberglass Shelter

Class C Fire Rated

Our roof materials carry a “Class C” designation for the CAN/ULC S107 (2010) Methods of Fire Tests of Roof Coverings and ASTM E108 (2011) Standard Test Methods For Fire Tests of Roof Coverings. An independent testing agency ran the following tests on our materials to certify our “Class C” designation.

  • Spread of Flames Test - This test measures how quickly the fire spreads when a fan blows a flame onto the roof material for a sustained amount of time
  • Intermittent Flame Test - This is similar to the Spread of Flame test but exposes the flame to the roof material on an intermittent basis, exposing it, then stopping, then exposing it, then stopping.
  • Burning Brand Test - This test puts a combustible material on top of the roof to see what difference that makes on the test

In all cases, it passed for the “Class C” designation and in all three tests, there was no flaming of the underside of the deck.

  • Watertight - molded and integrated as one piece
  • Leak-resistant - no seams or areas for potential leaks.
  • Easy access - available with hinged springs or steel lifting eyes

Whatever you needs, our engineers can design a solution for you.  Watch the video to learn more.

Roofs with Integrated Skylights

Need to add natural lighting to your shelter?  Our design team can typically add one or more skylights to virtually any area on your shelter's roof. 

Plus, our skylights are guaranteed not to leak.  

We employ a unique manufacturing process that allows us to seamlessly integrate translucent sheets into the shelter's roof.  Rather than cutting a hole in the roof and adding a skylight, our skylights are a manufactured into the shelter.
