Rubber roofing is the best option owing to its durability, strength, and cost-effectiveness. They are especially preferred for flat roofs and low-slope roofs. Its resistance to weather and energy efficiency makes it a popular choice. However, it is essential to research about the options of rubber roofing before installing them. Installing the wrong roofing material will only lead to further damage. In this article, we discuss the types of rubber roofing and ways to maintain them.
What is Rubber Roofing?
A rubberized material is laid out across the length of a flat roof and then tightly adhered, creating a water-resistant seal. It keeps the roof dry and prevents it from rotting because of its water-resistant properties. The sloped roof works well by draining water off the roof naturally, but low-slope roofs are almost flat, which leads to water accumulation on the roof. Later, water might seep into the roofs and cause leaks, algae, mold, and rot. Rubber roofing helps sort out all such issues.
Types of Rubber Roof
Let us have a look at the three types of rubber roofing available in the market.
EPDM
EPDM roofs or Ethylene propylene diene terpolymer roofs are highly durable materials that can be easily installed. These roofs are lightweight and resistant to extreme conditions. EPDM materials are also known for their long-lasting and break-resistant abilities. This makes them a popular choice for projects that need long-lasting coverage. They provide protection from the heat and sun. The rubber roofing material expands with heat but regains shape very easily.
There are a few cons of EPDM roofs as well. Although it is known for its durability, with time, UV radiation can break them down. They can also absorb heat and expand if not installed properly. They are more vulnerable to puncture than other options like TPO or PVC. This can break the water-tight seal and damage the whole roofing system. They are best suited for structures with less foot traffic. Since EPDM is a new roofing technology, not everyone is an expert in installing it. Hence, a professional is required to install the roofing.
TPO
TPO stands for Thermoplastic polyolefin roofing. They are flexible, durable, and easy to install. They are also UV-resistant and energy-efficient. It is unique when compared to other rubber roofing types, as it needs to be welded with a heat gun. TPO roofs are traditionally white, which helps the roof to reflect the heat away from your home. They are suitable for residential and commercial structures. They can also reduce greenhouse gas emissions over time.
It is expensive as compared to EPDM. It degrades fast, yet can last for about 20-25 years. TPO can break easily when exposed to extreme weather conditions. Some people prefer EPDM over TPO because of its white color, as it gets dirty easily.
PVC
PVC roofing or Polyvinyl chloride rubber roofing is the most flexible and leak-resistant. It is made up of synthetic or natural rubber with fire-resistant features. It is very similar to TPO in its chemical composition and white colour and even the installation practice. It is opted for by homeowners who want leak-proof, puncture-proof, wind-resistant, and waterproof roofing material.
Despite its similarity to TPO, PVC is not the preferred choice for most people because of its drawbacks. They can contaminate water runoff, unlike TPO and can release toxins when it breaks down. It also has high installation charges and needs replacement frequently as compared to EPDM. It is also the most expensive of all the options. PVC rubber roofing has welded seams which may last up to 20 years.
How to Maintain a Rubber Roof?
Rubber roofs are generally low maintenance due to their resistance to water and wind. However, there are a few things you should keep in mind for better maintenance of the roof.
-
You should get your roof inspected every year to check for any leaks to prevent further damage to the roof.
-
You should get the roof cleaned professionally to prevent the accumulation of dirt and debris.
-
Get the gutters cleaned occasionally to prevent too much water from pooling over the roof.
Choosing the Right Material
Choosing the right roofing type is important, which depends on certain factors. Hence, look for factors before deciding on the right choice for you:
-
Pricing: EPDM costs less per square foot, whereas PVC is generally the most expensive.
-
Durability: Most materials are almost equally durable, but don’t forget to consider your climatic condition and extent of exposure to UV rays.
-
Energy Efficiency: TPO and PVC are highly reflective, which makes them a better choice to reduce energy costs.
-
Roof Deck: The condition of your roof deck matters when choosing the right option. EPDM can only be installed on strong roof structures.
Conclusion
Choose the right option of roofing material that suits your needs. The rubber roofing material is an option you can consider owing to its advantages. However, consider its disadvantages too. Also, look for professional assistance, as the proper installation of the roofing is as important as selecting the best material.
