What Goes Under EPDM Roofing?
EPDM, or extended-pitch rubber roofing, has one of the longest service lives of any flat roofing. If properly maintained, EPDM roofing can last more than 50 years. In addition to its durability, EPDM is environmentally friendly and will reduce your climate control costs. In warmer climates, EPDM roofing is available in light colors, which reflect heat and add an additional 30% to the square-foot price. These advantages make EPDM roofing a great choice for roof over applications. roofing supply
EPDM roofing is usually black or white in color. While black EPDM absorbs heat, white will reflect sunlight, helping your home stay cooler. This kind of roofing also requires very little maintenance, and the only maintenance required is repainting every decade or so. For this reason, many contractors recommend installing an underlayment in addition to EPDM roofing. While the material is durable, it is still important to remember that it is not a modified rubber roof.
EPDM roofs are fairly easy to install, but improper installation can lead to expensive repairs. It is also not very attractive – it is made from rubber. It is also not aesthetically pleasing, so you’ll want to hire a professional to install it correctly. However, this type of roofing is easy to install if you follow the proper installation procedures. If you’re not familiar with how EPDM roofing works, consider these tips.
Another benefit of EPDM is its ease of repair. Once the membrane is damaged, it is possible to repair it with a patch made of synthetic rubber. Apply EPDM primer with a paintbrush or roller. Apply the primer generously and spread it to the edges. Pressure-sensitive patches can be applied without a backing, while glue-down types are stuck to the roof with EPDM adhesive. Apply lap sealant to the edges to prevent leaks from forming.
When installing EPDM roofing, it is crucial to prepare the surface. The flat timber decking underneath should be completely dry before the membrane is applied. If it is wet, EPDM will not be able to perform as expected after installation. It should also be as clean as possible, as rust, grease, and oil can interfere with the installation process. Then, the EPDM roofing can be installed. If it is successful, you can enjoy a new roof in no time!
The membrane is generally placed on top of insulation that is attached to the roof deck with ballast. Once installed, the EPDM membrane should be adhered to the roof with a chemical adhesive and dry for five to twenty minutes. The longer the EPDM roofing is adhered, the less leaks it will experience. However, fully adhered EPDM roofing systems should be installed by an experienced contractor with experience and skill. The roof should also be clean, and the deck should be sanded before the installation.
EPDM roofing contractors are able to perform many different tasks. They are also able to install EPDM roofing over wood-framed roofs. To do this, the roof will be stripped to remove all debris, sharp objects, and holes. The new roofing will be installed over this and secured with ring-shank nails. After the roofing is installed, the old concrete roof will be pressure washed and patched.
