How Your Roof Is Constructed

Metal Roof Deck

EverGuard® TPO

EverGuard® TPO is a flexible and highly‐reflective single-ply membrane that offers superior long‐term weathering against the elements. If you are looking for great performance at a cost effective price, then look no further than classic EverGuard® TPO. This product can be installed during a variety of times throughout the year and is guaranteed up to 30 years.

Plywood Roof Deck

EverGuard Extreme® TPO

EverGuard Extreme® TPO is the best‐performing single-ply membrane that you can buy for your property. This TPO provides next-generation performance against heat aging and UV inhibitors, which are the two key performance characteristics related to TPO longevity. EverGuard Extreme® TPO outperforms the competition based on heat‐aging tests, which is why we back this product with the industry’s best guarantees: up to 35 years!

Lightweight Concrete Roof Deck

EverGuard® PVC

EverGuard® PVC is a high performing single‐ply membrane that provides UV and fire resistance. EverGuard® PVC XK is manufactured with KEE Elvaloy which offers built‐in resistance to grease, oil, and chemicals. Similar to TPO, it is a flexible roofing membrane with high reflectivity that results in increased energy savings. PVC membranes can be installed in a variety of ways and are guaranteed up to 25 years.

Metal Roof Deck

Built‐Up Roofing (BUR)

GAFGLAS® Built‐Up roof systems are made up of asphaltic BUR sheets that are reinforced with fiberglass mats. These systems are “built‐up” on the roof using alternating layers of hot asphalt and BUR sheets. This proven technology provides a strong, durable roof membrane with redundant, multi‐layer protection and you can add a reflective cap sheet as well.

Plywood Roof Deck

Modified Bitumen

RUBEROID® roof systems utilize asphaltic membranes modified with SBS or APP bitumen and reinforced with fiberglass or polyester mats to produce a strong and flexible waterproofing membrane. These systems are very versatile and can be installed using hot asphalt, cold adhesive, torch applied or self‐adhered.

Metal Roof Deck

Coating Solutions

TOPCOAT® is a full line of reflective coatings and liquid membranes for all types of metal and low slope roofing that provides an extra protection layer and extends the life of the membrane below. TOPCOAT® systems save energy costs by reflecting heat and harmful UV away from the building and thereby reducing the temperature in the building.

EnergyGuard PolyIso Roof Insulation

EnergyGuard™ PolyIso Roof Insulation

EnergyGuard™ Polyiso Insulation board is made of glass fiber‐reinforced cellulosic felt facers bonded to a core of isocyanurate foam. It provides high insulation value and superior LTTR value compared to any other FM Class I rated product of equivalent thickness at 5.7 per inch. In addition, EnergyGuard™ ISO offers unique 6" on the center guideline facer design to increase speed and increased accuracy of installation.

EnergyGuard Perlite Roof Insulation

EnergyGuard™ HD & HD Plus

EnergyGuard™ HD & HD Plus use a coated glass facer bonded to a polyiso foam. It offers improved fire resistance–achieves a Class A rating over combustible decks without the use of a gypsum board or fire rated slip sheet. A total of at least 3" of Energyguard™ is required. Offers added protection for hail prone areas or roof decks with heavy traffic with compression strengthen of 80 psi or 110 psi.

EnergyGuard Perlite Roof Insulation

EnergyGuard™ Perlite

EnergyGuard™ Perlite roof insulation is a homogeneous board composed of expanded perlite particles, selected binders and cellulose fibers, which give EnergyGuard™ Perlite roof insulation its insulating efficiency. The surface is treated to reduce bitumen absorption assuring proper adhesion of roof membranes.

EnergyGuard™ offers stable insulating properties and exceptional fire resistance not to mention excellent dimensional stability.

EnergyGuard Perlite Roof Insulation

Cover Boards

EnergyGuard™ Composite Board Roof Insulation consists of an isocyanurate foam core integrally bonded to ½” thick EnergyGuard™ High Density Fiberboard or EnergyGuard™ perlite on one side and a strong organic glass facer sheet on the other. The excellent insulating qualities of Polyiso foam are combined with the strong surface characteristics of high density fiberboard or perlite.

Metal Roof Deck

Metal Decks

Metal decks are corrugated panels provided in a variety of gauge thicknesses and flute spans. They are the most common deck type and provide good overall performance while not breaking the budget. Metal decks also provide good wind resistance and excellent external fire and seismic resistance.

Plywood Roof Deck

Wood Decks

Wood decks are typically made of either plywood or OSB. These decks are found more frequently out in the western region of the US due to their excellent seismic resistance. Wood decks have fair to poor performance in fire and wind resistance as well as foot traffic.

Lightweight Concrete Roof Deck

Light Weight Insulating Concrete Decks

Lightweight Insulating Concrete Decks are non-structural and low-density. They can be placed upon a various structural deck systems that have been designed to carry loads such as concrete or metal. LWIC roof decks often contain encapsulated EPS (Expanded Polystyrene) insulation and typically have good resistance to fire, wind and heavy foot traffic.

Structural Concrete Roof Deck

Structural Concrete Decks

Structural concrete decks serve as an integral part of the structure and are designed to carry heavy loads. They have excellent resistance to foot traffic, fire and wind however they are typically one the more expensive options.

* When installed properly, this system will help reduce energy costs. Actual savings will vary based on geographic location and individual building characteristics. For more information, contact GAF Technical Services at 1-800-ROOF-411, or visit
