Industrial Roofing

There are different roofing materials that come in use when talking about EPDM installation, most commercial roofing companies use roofing materials from different manufacturers but at the end of the day, it is all the same material that needs to be used in the process of installing an EPDM roof. Here are some roofing materials that are used in EPDM roof installation.

Polyiso Board

Polyisocyanurate (ISO) board is a plastic that is thermoset, it is typically produced as a foam and used as rigid thermal insulation. It is made of glass fiber-reinforced cellulosic felt facers bonded to a core of isocyanurate foam. polyiso boards are designed to use in practically any low-slope roof application, including built-up roofs, modified bitumen or most single-ply roofing systems. Because of its lightweight polyisi boards are easy to handle on the job site and installs faster, Easier cutting in the field provides the installer with simplified fabricating on the roof deck. Polyiso board can be easily painted and stained with water-based products as it has a bright white surface. An unpainted board can be wiped clean as necessary. Filler products or adhesives can repair any damaged boards during installation prior to painting. It is also not a material affected by water vapor or water and can be successfully used in bathrooms, kitchens, and indoor swimming pools

The tongue and groove application allow adjacent boards to interlock, creating a continuous insulated surface. Boards are available in standard thickness and lengths to fit most applications. Installation is easily accomplished by both commercial roofing companies and DIY enthusiasts. The lightweight nature of polyiso board means installation proceeds quickly.

Polyiso board is proven safe when put through fire situations, both through actual events and laboratory testing. polyiso board shrinks away from flame sources, with no flaming droplets or flame spread characteristics.

When it comes to choosing the best overall insulation product for your low-slope roof, for most commercial roofing companies it would be hard to beat a tried-and-true product like ISO panels.

Cover Board

A cover board is a substrate. A substrate is the material that the roof membrane adheres to. However, it is far more useful than just a typical substrate, they also serve a critical purpose in increasing the life of flat roofs, the impact of hail can be minimized with using a cover board, hail damage without overboard can piece through the insulation which will increase the heat flow through it, which will then add on to the commercial buildings energy costs. Cover board as a barrier against the external impacts of the environment like a fire, they also provide a strong high-performing layer of defense which the wind uplift value of the roof. The National Roofing Contractors Association (NRCA) has endorsed the use of cover boards in all low-slope roofs due to the insulation’s negative attributes like facer delamination, powdering, shrinkage, cupping, and edge cavitation. Cover boards help support the insulation in the event of these failures. All these uses of cover boards provide added security and lower cost of ownership for the building.

There are different types of cover boards and they have different properties, for every desired result there is a feature and benefit suited. The cover board provides a barrier for the fire which significantly increases the time it takes to melt the insulation, which adds fuels to the flames. It also serves as a vapor retarder and a substrate.

Roof Drains

Roof drains come in few standard sizes for low-slope or flat roofs. The type of application depends on several factors, such as the size and slope of the roof, the desired appearance, and how much regular maintenance the drain system might need. Sizing the drains for each system, including the number of drains required, is based on factors such as the roof area, the drain location(s), the inflow rate and desired drainage rate, and the expected rainfall volume.

Sizing a Roof Water Drain

Calculating the surface area of the roof the drain will be covering and the average hourly rainfall at the location will be the first step to determining the size of the roof drain.The next step is to determine each roof area that will be served by a separate leader (drain pipe, scupper, or downspout). The drain or pipe manufacturer is where this information can be obtained.

Next, the roof area is divided by the area for each leader to determine the number of drains required. Each leader must be large enough to handle the volume of water to be drained—the greater the leader capacity, the fewer roof drains are needed. Usually, roof drains are equally spaced and are located in low points of the roof or in any areas where water accumulates.

Scupper Drains

Scuppers are commonly used on flat roofs that have a parapet or other type of perimeter barrier enclosing the roof. Scuppers are channels or open holes cut into the roof edge or parapet. The roof is sloped toward the scuppers, and water simply drains out through the scuppers. A scupper may drain into a downspout on the exterior of the building, or it may have an extended chute or pipe that directs a stream of water away from the building.

Inner Roof Drains

Inner roof drains are used on flat roofs and include a low section or channel that collects water and feeds it into a concealed drain that leads to an underground drainage system. It is hidden to a viewer the actual benefit of the inner roof drains. Inner drains can require maintenance to prevent problems but they are mostly resistant to freezing.

Siphonic Roof Drain

Siphoning is used as a drainage mechanism for a siphonic roof drain, resulting in drainage that is faster and far more efficient than that of any other type of roof drain. These advantages have made them increasingly popular with commercial roofing contractors that understand the importance of reliable roof drainage. There are a minimum number of drains used for the installation as these are usually installed on flat commercial roofs, and all of the drains can be connected to a single leader. Other drain systems may be more on the cheaper side while siphonic drains tend to cost more, but they work smoothly and require relatively little maintenance. Because the siphoning force helps move the water, siphonic drain systems can employ horizontal leaders instead of sloped pipes, which rely on gravity alone for drainage.

Coping Covers

Coping covers are horizontal top surfaces of walls are the most vulnerable point of water to enter the wall. Copper flashing alone can be a way of protecting this surface or the combination of precast concrete.

Cover Tape

This roofing material is made in a peel and stick application, and has exceptional adhesion, and long-term chemical and heat resistance which gives tape the ability to remain flexible in harsh conditions. Cover tapes are used for typical roofing applications such as cover for most metal terminations including gravel stops and drip edge, it is also used for horizontal patching, seam overlays, and seam repairs. This roofing material can be used with EPDM, TPO, and most PVC roofing membranes, a special primer for each one is required.

Seam Tape

This roofing material is a vulcanized, black rubber adhesive tape design to provide high strength, watertight joints in single ply EPDM membrane. It is a tacky and soft quick grab to EPDM but also possesses high initial strength. There is excellent adhesion to a non-polar and polar substrate such as metal, glass, concrete, masonry, and plastics.

Bonding Adhesive

It is a high strength solvent based contact adhesive that allows quick bonding to EPDM membrane and cured flashings to various porous and non-porous substrate. Water based adhesives should only be used if the temperature is upwards from 40 degrees or they will not cure properly. Solvent based adhesives are a lot more forgiving when it comes to curing temperature requirements, but can be more hazardous to work with. Solvent based can be used in the winter, as long as it is kept warm before application.

EPDM Thickness

There are 3 different thicknesses to EPDM; the 45 mil which is for the light-duty roofs used for residential roofing, the 60 mil which is the most common for commercial roofing, and the 90 mil which is the heavy industrial. Commercial roofing companies like Infinite Roofing and Construction use the best brands for any roofing materials purchased, they guarantee a long-lasting and perfect work.
