Roofing a factory or a commercial building can look like an insurmountable task. But it won’t be so if you know the basics of industrial roofing. Understanding the terms used by a roofing industry is essential to make sure you select the right roof for your building.
The process of commercial and industrial roofing starts with the selection of the right roofing material. Here are a few commonly used roofing materials:
1.EPDM or Ethylene propylene diene monomer is a type of synthetic rubber. This roofing material is used for low slope or flat roofs. They come in sheets or rolls which a roofer has to overlap and bind together with the help of bonding cement, ballasts or mechanical fasteners. Since they are a synthetic rubber, they provide a water-tight seal to your roof.
These are lightweight and do not require heating for installation, this makes it quicker and easy to install. But care has to be taken while installing it. If it is not done correctly, there’s a high risk that it will fall apart. They are resistant and UV-resistant as well. One disadvantage of EPDM is that they are a bit expensive to install.
2.TPO or Thermoplastic olefin is a type of single ply roofing membrane. This membrane has the following three layers (from bottom to top):
2)Polyester-reinforced fabric (scrim)
3)Thermoplastic polyolefin ply
TPO provides good insulation to the building which helps in reducing electricity costs. They are hot-air weldable and are as UV and heat-resistant as EPDM.
It has been observed that TPO roofs cannot handle excessive heat load. If the material is subjected to high thermal conditions, it will start to deteriorate. It is advisable that the contractor must align the inside edge of the nozzle with the edge of the roller so that there’s no welder drag.
3.Metal roofing is relatively older than the other two discussed above. Some benefits of metal roofing include portability, durability, waterproof, low-maintenance, fireproof, windproof and easy snow-shedding. Metal roofs are also very easy to install.
Aluminum is a light metal, has high corrosion resistance and is relatively inexpensive. This makes it an ideal choice for metal roof installation. The only downside of using metals is that they do not provide good heat insulation.
If you choose other materials such as copper, zinc or galvanized steel, the cost of the roofing will be very high.
Important factors to consider:
The factors on which you can decide the material are its durability, heat resistance, maintenance requirement, material color and cost of installation. You should decide the material by keeping in mind your short and long term goals and the weather conditions of your area.
You should keep all these factors in mind while speaking to a roofer. You can also ask them to suggest the best material for you. A good roofer will be able to suggest you the best material and will be able to tell you what advantages you will have if you select that material.
