Cost To Replace An Epdm Roof

What is EPDM Rubber flat roofing?

Replacing may cost a little bit more than just applying EPDM rubber roofing to your home. If you need to remove the old roof, youll probably have to add about $1 to $2 more per square foot. Codes will vary from area to area, but if theres only one layer, you most likely wont need to remove the old roof. Two or more layers will typically require removal, though.

Cons Of Epdm Roofing:

  • Absorbs heat. EPDM is naturally black, so it offers less heat protection than rubber roof materials that are lighter in color. EPDM can be ordered in grey or white for an additional cost.
  • Potential weak seams. EPDM seams are sealed with adhesive or tape, which leaves them more prone to leaking than hot air-welded seams.

2. TPO

Thermoplastic polyolefin, or TPO, is a single-ply roofing material that is similar to EPDM but different in several key ways. First, TPO is a relatively new product in the roofing industry, which means its not as time-tested as EPDM and PVC roofing.

However, TPO was created as a more economical and energy-efficient alternative to these other rubber roofing materials, making it a popular choice.

Detailed Information On Epdm Rubber

EPDM stands for ethylene propylene diene monomer, and that is the chemical name of the synthetic rubber useful in a wide range of applications, including flat roofs, but also for door and window seals in vehicles, non-slip coatings for playgrounds and decks, and much more.

The ethylene, propylene, and diene comonomer can be crosslinked via Sulfur vulcanisation thanks to the last ingredient. EPDM is an M-Class rubber, meaning that it is an elastomer with a saturated chain of the polyethene type . EPR was the predecessor of EPDM, but it could only be crosslinked with peroxides and other radical techniques. Thanks to adding the diene units, the process of creating rubber became much easier.

EPDM and other kinds of rubber with saturated polymer backbones are much more resistant to ozone, light, and heat than the unsaturated variants, such as SBR, natural rubber, or polychloroprene . EPDM can be prepared in such a way it can stand as high temperatures as 150 °C. With correct installation, it can be used as a roofing material or another outdoor solution and serve for many years or even decades without much damage.

Advantages To Using Epdm Roofing

The biggest advantage that EPDM roofing has over other types of flat roofing materials is its cost. At .80 a square foot, this is one of the most inexpensive roofing materials around. Its also extremely easy to install, so whether you do it yourself or you hire a professional, the costs are low in that area as well.

EPDM rubber roofing is also very lightweight, so the roof deck doesnt need any kind of reinforcement. In fact, the best way to install this material is to strip everything right off the roof, apply an adhesive then roll out the roofing. Because there are few seams, leaks are fairly rare and a good quality EPDM roof can last up to 20 years.

Installers also have options of how they will install the material. In addition to using adhesive to attach hit to the roof, there are also fasteners that can be used to anchor it in difficult to reach areas. It can also be ballasted with stone, which may help to improve its appearance.

This type of roofing is fairly durable, doesnt scratch or scuff easily, and can be easily repaired if a leak does occur. Liquid roofing membranes, latex tape or adhesives, and some types of rubber shingles can be installed over the EPDM roofing to repair and patch leaks that may develop over time. And while the material is black and does absorb heat, it isnt easily damaged by UV rays, which helps it hold up well in sunny climates.

    Epdm Wins A Nobel Prize

    A German scientist called Karl Ziegler is responsible for the scientific breakthrough that led to the EPDM production process, while working on polymerisation. He realised that there were traces of nickel in the autoclave used for the reactions, which caused the reaction to stop. By using a titanium and aluminium-based catalyst instead, and carrying out the reaction under atmospheric conditions, Ziegler and his students discovered that not only could the reaction be accelerated, but it produced a polymer that was strong, flexible and had a high tolerance for heat and cold. In addition, this could be done at normal pressure.

    Before this discovery, ethylene had been considered difficult to polymerise, with high pressures and high temperatures needed. The polyethylene that came from Zieglers discovery was therefore not only easier to produce, but also was more rigid and had a better resistance to high temperatures than its high-pressure counterpart. Within 3 years of the discovery, 200 metric tons of the new plastic had been produced.

    Ziegler disclosed his catalyst to the Montecatini Company, where an Italian scientist called Giulio Natta was acting as a consultant. Natta expanded on Zieglers work, and the Ziegler-Natta catalyst was born. In 1963, Karl Ziegler and Giulio Natta were awarded the Nobel Prize for Chemistry for their work on controlled polymerisation, which greatly enhanced the progress of plastics and their applications.

    Alternatives To Epdm Roofs

    While EPDM roofs are popular, they arent the only option if you want to install or already have a flat roof. These other materials are alternatives to EPDM, and depending on your needs, its important to understand the benefits and disadvantages of each.

    Other Single Ply: Polyvinyl chloride roofs are excellent at reflecting heat. Theyre also ideal for restaurants, as animal fats and chemicals are easily cleaned from them. Thermoplastic polyolefin is another highly popular roofing membrane material and is similarly lightweight and reflective. However, these types can be more easily damaged than an EPDM roof coating.

    Asphalt: A cheap and durable roofing material, asphalt is easy to install and repair. It can be shaped to the form of any rooftop vents or features your building has. However, asphalt is heavy and absorbs heat. Over time it will dry out and crack, and cause leaks around your vents unless regularly maintained.

    Metal: Metal roofs come in a variety of styles and may better match the aesthetic of your business. They also require few repairs and excel at protecting a building from the elements, including heat, which they reflect in abundance. However, metal roofs are costly to purchase and install and may not be appropriate for your business.

    How Much Does A Rubber Roof Cost

    Single-ply rubber roofing costs anywhere from $1 to $12 per square foot.

    The final cost largely depends on the specific material. The thickness of said material and whether the installer fully adheres , mechanically fastens , or uses ballast , also plays a role in pricing.

    Additionally, project costs will increase if you need to tear off existing materials and add decking or insulation during the roof replacement. Penetrations such as skylights, HVAC units, and chimneys will also add to costs as they introduce more roof installation complications.

    Pros And Cons Of Rubber Roofing

    How to install an EPDM Flat Rubber Roof, ClassicBond

    Rubber roofing is something a lot of homeowners have probably never heard of or certainly never considered for their own home. But perhaps it is the time that many of them did.

    This article is not designed to encourage the homeowner to buy one particular type of roof, but rather to arm the homeowner with enough facts and knowledge so the homeowner can make in informed roofing decision.

    A rubber roof, known in the roofing business as an EPDM roof, has a lot of advantages and only a few disadvantages. One of the big advantages to rubber is the cost. Although a homeowner must use a licensed installer to lay down this roof, the cost of the entire job still favorably compares to the cost for other types of roofing. Not only is the roofing material itself less expensive than most other choices, but the product is also lightweight, and installation is fast and easy, reducing labor and installation costs. The rubber is glued into place, negating the use of heat, which can adversely affect a homeowners insurance policy.

    Another large advantage of rubber is that if the roof ever does have a leak, repairs are fast, easy and extremely inexpensive. In many cases a tube of liquid rubber is all that is needed in other cases, a special tape designed specifically for repairing rubber will do the job. In any event, repairing one of these roofs, if and when it should become necessary, is almost never a problem.

    Rubber Will Inevitably Shrink = Leaks

    Another inherent design problem is that after a few years, this roof membrane simply begins to shrink, slowly pulling away from parapet walls, flashings, corners, drains and other areas. At that point, leaks start penetrating these weak points. Shrinkage is a particularly serious problem on a larger size roof.

    The Pros And Cons Of Using Epdm

    As one of the upcoming and increasingly popular roofing options for trade and those who are wanting a straightforward roofing solution that they can do themselves, it is important you know what the pros and cons are when using EPDM on your roof.

    Below we will go into some detail on the main advantages and disadvantages of using this option for your own project.

    How To Maintain Epdm Rubber Roofing

    While rubberised roofing is extremely durable and damage resistant, over time it will require cleaning and occasional repairs. Protecting the material is a relatively straightforward process that will ensure you get the most out of the system.

    Cleaning the rubber will help to maintain the strength of the surface. Ensuring that a cleaning procedure is in place will ensure it remains resistant to potential heat cracks.

    Rubber Roofing System

    Any debris on the roof such as leaves or stones need to be swept away and gutters must be cleared. For any stubborn dirt such as moss or algae, a combination of warm water and dishwashing soap should suffice.

    As is the case with the maintenance of any roof, prevention is always better than the cure. Inspecting and cleaning the roof at least 2-4 times a year will enable you to keep on top anything that requires attention. The sooner any damage is spotted, the faster it can be repaired without running up unnecessarily high bills.
