What thickness of EPDM is best?

An EPDM roof with a thickness of 45 Mils should last around twelve years. If your roof is 90 Mils thick, it might last more than twenty-five years. However, continued exposure to hot humid weather or sub-zero freezing temperatures may negatively impact the life of your roof.

How long does 60 EPDM last?

EPDM roof membranes remain stable over time and can have a life expectancy of over 50 years.

Which is thicker 45 or 60 mil?

(A mil is a unit of measure where 1-mil is equal to 0.001 inches. So, a 45-mil roofing membrane is actually 0.045 inches thick; whereas a 60-mil membrane is 0.06 inches thick, and so on.)

Which EPDM is best?

Are there different types of EPDM?

The three types of EPDM installation are ballasted, fully adhered and mechanically attached.

Which Thickness of rubber roofing is best for my roof? (1.2mm or 1.5mm)

How many layers is EPDM?

EPDM Roofing Membrane Details

EPDM roofing consists of four layers, making it one of the most durable and long-lasting roof membranes available.

Is all EPDM the same?

EPDM can be used in a variety of different ways, as we'll see shortly, but it's really come into its own in the flat and low-pitched roofing sector due to its strength and resistance to weathering, as well as the fact that EPDM sheeting allows for a consistent application and thickness across the entire roof area.

Can you double layer EPDM?

For flat roofs, materials such as EPDM and TPO are usually approved for use up to two layers.

What is the minimum pitch for an EPDM roof?

(A minimum slope of 0.25 inches per foot [2 percent] is recommended for all low-slope roofing systems.) For adhered systems, the substrate must be one that is approved by the system supplier. Higher-density products provide improved impact resistance.

Does EPDM have to be glued down?

When you are fitting an EPDM roof, you need to make sure that it is glued down properly. During the membrane application process, you will need to apply two different types of adhesive. The first is a water-based adhesive. Use Permaroof deck adhesive for the best results.

Which is better EPDM or TPO?

TPO has better dimensional stability than EPDM. EPDM is more likely to shrink which can cause a variety of problems on your roof.

What is thicker 30 mil or 60 mil?

While the minimum thickness of 30 mil PVC is minus 5% (-1.5 mils )(0.0015”) the minimum thickness for 60 mil textured HDPE is minus 15% (-9 mils) (0.0090”). PVC maintains much closer control of the thickness of the material in the manufacturing process.

How thick is a flat roof?

These are formed into large sheets ranging in thickness from 1.2-2.0mm and usually supplied in rolls 1-2m wide and up to 20m long. Some products are supplied in large sheets to fit the roof and delivered folded up.

Can you walk on EPDM rubber roofing?

Full Answer. All of our roofing systems are designed to take foot traffic and will withstand access to the roof for window cleaning and general maintenance The EPDM systems can be walked on both during and after installation, EPDM is designed to take LIGHT foot traffic for occasional cleaning or maintenance.

Can you put gravel on EPDM?

Yes, it is possible to cover the membrane with gravel, pavers or bankirai wood but the membrane must always be fully adhered to the substrate.

What is better EPDM or PVC?

Comprised of synthetic rubber, an ethylene propylene diene monomer (EPDM) roofing membrane offers superior weather resistance while remaining a cost-effective option. PVC, on the other hand, delivers exceptional seam strength; in fact, heat-welded PVC seams are stronger than the PVC roofing membrane itself.

Can you install EPDM on a pitched roof?

Don't forget EPDM membranes can be used on pitched as well as flat roofs. They can be used on virtually any building anywhere!

Can you glue EPDM to plywood?

EPDM should be bonded over 5/8" plywood, 5/8" OSB board, or polyisocyanurate board with a fiberglass backing.

What type of roofing is best for a low pitch roof?

Rubber roofs are a top choice for flat or low pitched roofing as it adheres to the roofing materials below it and, when installed correctly, provides a watertight seal to the elements. Choosing the best low slope roof materials often comes down to weighing the pros and cons based on your home and your needs.

Can you stick EPDM to EPDM?

Overlap the two rubber membranes by 75mm (3inches)

Overlap the two rubber membrane sheets to be joined by 75mm (3inches). It is common on long runs to overlap the two sheets by more than 3" and then cut back the top sheet of rubber membrane once the splice tape has been stuck to the bottom sheet.

Can you lay new rubber roof over old rubber roof?

Anyone with a rubber roof that needs replaced. The two requirements to install the new membrane directly over top of the old rubber is 1) that the existing insulation not be saturated with moisture and 2) that the deck is not rotten or rusted to the point that it cannot hold a screw.

How long does EPDM rubber last?

An EPDM rubber roof is incredibly long-lasting and durable. The rubber recycled and used for the synthetic rubber membrane isn't damaged under the sun's UV or ultraviolet rays. If installed correctly, you can expect a rubber roof to in excess of up to 50 years.

Can you use silicone on EPDM?

Not all Dicor caulk is designed for EPDM roofs. You have to read to label. Silicone will NOT adhere to rubber. You can peel it right off.

Is silicone or EPDM better?

EPDM has good tear strength and is seen as the more durable rubber compared to silicone. However, silicone is more flexible and can be formulated to have very strong tear resistance and elongation, ideal for vacuum membranes.
