A variety of materials may be used for shelter roofs. They depend on the site, budget, long term maintenance and owner preference. Typical factory supplied options are asphalt shingles, “R” panel or multi-rib, and standing seam metal roofing. All standard metal roofing is Kynar painted over galvanized steel, which offers reduced color fade over time.

SunSky | Multi-Rib Roofing is most often used as an inexpensive combined roof and roof deck system. The 24-gauge galvanized steel panel comes with a Kynar color paint on top and white prime paint on the ceiling surface. Multi-Rib roofing is supplied pre-cut to length and angle. Poligon makes special trim as required. The metal roof deck is attached with exposed fasteners with gaskets. When metal roof deck is used alone as roofing, roof deck condensation can occur. If condensation is a problem, roofing should be used with a roof deck. Both 2×6 t&G or SIP panel roof decks with exposed wood ceilings are available. | |

|
| Multi-Rib Roofing can be used alone, or in combination with any of the following sub-roofing types: | |
 |
T&G Wood Roof Deck of nominal 2×6 tongue and groove lumber makes for a warm interior finish. The random length 2×6 T&G is field cut and screwed in place in the field. In the field, the plank should be sealed with a weather resistant finish (supplied by others). Roof deck is always covered with a 30# felt supplied with a roofing package. If no roofing package is supplied, the felt must be supplied by others. |
 |
SIPs (Structural Insulated Panels) are preferred when an insulation system is required. Most common Poligon SIP roof panels are made with exterior rough sawn reverse board and batten 5/8” plywood with grooves 4” O.C. as a ceiling surface. The core is 3-5/8” EPS and the roof deck is 7/16” OSB. |
 |
|
| Standing Seam metal roofing is another roofing systems option. Standing Seam is furnished in Kynar colors, and avoids the through-roof screws seen in Multi Rib while creating a long-lasting and tighter system. Standing Seam uses a series of clips that are covered in a lapping seam system to attach to the roof. Standing Seam roofing is not factory pre-cut to angle. Standing Seam does not have the span capacity of Multi Rib systems and may require more purlins when used alone. Standing Seam is most often used with a supporting roof deck. | |

T&G Wood Roof Deck of nominal 2×6 tongue and groove lumber makes for a warm interior finish. The random length 2×6 T&G is field cut and screwed in place in the field. In the field, the plank should be sealed with a weather resistant finish (supplied by others). Roof deck is always covered with a 30# felt supplied with a roofing package. If no roofing package is supplied, the felt must be supplied by others. |

SIPs (Structural Insulated Panels) are preferred when an insulation system is required. Most common Poligon SIP roof panels are made with exterior rough sawn reverse board and batten 5/8” plywood with grooves 4” O.C. as a ceiling surface. The core is 3-5/8” EPS and the roof deck is 7/16” OSB. |
 |
Another option for SIP ceiling surface is a white, embossed metal over OSB. These panels are tested and rated for structural loads as roof decks. 4-1/2” SIPs have an “R” value of 15.2. |
