Choosing the right EPDM flat roof material can be a daunting task, especially for DIY enthusiasts. EPDM (Ethylene Propylene Diene Monomer) is a popular choice due to its durability and resistance to weathering.

EPDM flat roof materials are made from a synthetic rubber compound that can withstand extreme temperatures, from -40°C to 120°C. This makes it an ideal choice for climates with harsh weather conditions.

A typical EPDM flat roof material is 1.5 to 3.8 mm thick, and its thickness determines its durability and lifespan. Thicker materials are more resistant to punctures and tears.

EPDM flat roof materials are also available in various colors and styles, including smooth and textured finishes. This allows homeowners to choose a material that complements their building's design and aesthetic.

Types of Flat Roof Materials

EPDM flat roofs are a popular choice, but they're not the only option. There are other types of flat roof materials to consider.

EPDM roofs come in three common thicknesses: 45 Mil, 60 Mil, and 90 Mil. Some manufacturers also offer a 75-mil EPDM membrane.

The thickness of the EPDM roof membrane directly correlates with its resistance to damage. Those in high-risk zones for flying debris and severe storm conditions will want to choose a robust thickness for their EPDM rubber roofing.

TPO (thermoplastic polyolefin) is another popular option, and it's growingly common as a single-ply roofing membrane. TPO membranes are also offered in varying thicknesses, which will affect the material's longevity.

Here are some key differences between TPO and EPDM:

PVC is another type of rubber roof material that's popular in the Florida market.

Materials

EPDM, or ethylene propylene diene monomer, is a popular choice for flat roofs due to its durability and versatility. EPDM stands for ethylene propylene diene monomer.

EPDM roofs come in different thicknesses, including 45 mil, 60 mil, 75 mil, and 90 mil. This thickness directly correlates with the material's resistance to damage.

EPDM is available in black or white, with the white version being an additional layer on top of the existing EPDM layers. The white version is known as FlexWhite and is designed to reflect sunlight.

EPDM roofs are made up of four layers, including an EPDM elastomeric base layer, an AFR fire retardant middle layer, a FRM polyester fiber reinforced top layer, and an optional white EPDM roofing top layer.

Here are some common thicknesses and their corresponding mils:

EPDM roofs are also available in widths ranging from 7.5 feet to 50 feet.

Florida Membranes

Florida's subtropical climate makes it a challenging environment for flat roofs. Rubber roofing membranes like EPDM are a popular choice for flat roofs in Florida.

EPDM is a type of rubber roofing membrane that's known for its durability and resistance to extreme weather conditions. It can withstand temperatures ranging from -40°F to 140°F.

EPDM is a popular choice for flat roofs in Florida because it's resistant to UV rays and ozone, which are common in the state's climate.

Tpo

TPO roofs are traditionally white, which can help reflect heat away from your home and lower your energy bill.

TPO roofs degrade a bit faster than EPDM, but you can still expect 20-25 years of life from this rubber roofing option.

White TPO roofs will appear much dirtier than black EPDM roofs, especially over time.

This is because dirt and debris can easily show up on a white surface, making it a less popular choice for homes or businesses with a view of the roof.

Advantages of Flat Roof Materials

EPDM flat roof materials have a lot to offer, and it's worth exploring their advantages. A long lifespan of up to 30 years is a significant benefit, especially when properly installed and maintained.

They're also incredibly resistant to weather conditions, which is a major plus in areas prone to high winds and heavy rainfall. This resistance is due in part to the fact that rubber roofs leave no way for wind to get under them and cause uplift.

The flexibility of EPDM roofs is another key advantage, allowing them to expand with heat and contract when it cools off. This helps them withstand the intense sun in Florida, reducing wear and tear on the roof.

Here are some of the key advantages of EPDM flat roof materials:

  • Long lifespan: up to 30 years
  • Weather resistance: resistant to high winds and water
  • Flexibility: withstands heat and sun exposure
  • Eco-friendly: leaves water clean and unaffected
  • Affordability: a cost-effective option

Roof Advantages

As a homeowner in Florida, you're probably looking for a roofing material that can withstand the state's unpredictable weather patterns. EPDM rubber roofs are a great option, lasting up to 30 years with proper installation and maintenance.

One of the most significant advantages of EPDM roofs is their weather resistance. Unlike shingles, they leave no way for wind to get under them and cause uplift, making them more resistant to high winds and water.

In fact, EPDM roofs are so flexible that they can expand with heat and then contract and regain their shape when it cools off. This flexibility means they get worn down by the sun much slower than other roofing materials.

EPDM roofs are also eco-friendly, leaving water clean and unaffected. This is especially important for homeowners who want to keep their local environment healthy and natural.

If you're worried about the cost, you'll be happy to know that EPDM roofs are generally affordable and not considered luxury roofing materials.

Here are some key benefits of EPDM roofs at a glance:

  • Long Lifespan: up to 30 years
  • Weather Resistance: resistant to high winds and water
  • Flexibility: expands and contracts with heat
  • Eco-Friendly: leaves water clean and unaffected
  • Affordability: generally affordable and not considered luxury roofing materials

In areas prone to hail, EPDM roofs are a great option. Hail stones simply bounce off, and with a thicker membrane and ballasted layer, you can ensure your roof stays intact. Plus, EPDM has an ozone-resistant rating of 'A' up to 100º F.

Least Expensive Option

EPDM roofing is the least expensive option among its competitors, including TPO and PVC. For example, a 2500sf EPDM roof would cost around $5.5/sf to install.

The cost savings are significant, especially when compared to TPO and PVC. A 2500sf TPO roof would cost roughly $7/sf to install, while a PVC roof would cost around $8.5/sf.

EPDM's affordability doesn't compromise its quality, as it's suitable for just about any roof type and promises decades of use.

Installation and Maintenance

EPDM flat roof materials are fast and easy to install, thanks to their large sheet size. A common roll size is 10′ wide and 100′ long.

This makes it quick to cover more area, unlike asphalt shingles which are only 3′ wide x 1′ tall. You can roll out EPDM to cover larger areas faster.

Easy to Install

EPDM is manufactured in large sheets or rolls, making it quick and easy to install. A common EPDM roll size is 10′ wide and 100′ long.

These large rolls can cover more area faster than traditional asphalt shingles, which are roughly 3′ wide x 1′ tall. You can simply roll out EPDM to cover more ground.

EPDM rolls are also light-weight, allowing you to cover more area in a shorter time for quick installation. This ultimately means a lower bottom line price for customers.

At only half a pound per square foot for 60 mil, fully-adhered, membrane-only EPDM, it’s significantly lighter than your average asphalt shingle, which weighs roughly 2.3lbs per square foot.

High-Wind Resistant

High-wind resistant EPDM roofs are a game-changer for areas prone to severe weather conditions. The large sheets or rolls of EPDM roofing material make it difficult for wind to get under and pick up, unlike smaller pieces of asphalt shingles, tiles, or metal sheets.

In fact, EPDM roofs are nearly 100% recyclable, which is a bonus for eco-conscious homeowners. This recyclability also helps reduce waste and minimize the environmental impact of roofing materials.

The seamless design of EPDM roofs also prevents wind from getting under the material, making them highly resistant to high winds. This is especially important for areas with frequent severe storms or flying debris.

Here are the common thicknesses of EPDM roof membranes:

The thickness of the EPDM roof membrane directly correlates with its resistance to damage. Homeowners in high-risk zones should opt for a more robust thickness to ensure their roof can withstand severe weather conditions.

Not DIY

Installing an EPDM roof is a complex task that requires expertise, and it's best left to a qualified professional. You can purchase EPDM at department stores like Home Depot, but that's not a substitute for proper installation.

Installing an EPDM roof incorrectly, such as on top of asphalt shingles, will lead to failure. This is a common mistake that can be avoided with professional guidance.

A qualified EPDM installer knows the specific requirements for a successful installation, and they'll ensure that the job is done right.
