TPO Roofing: Easy on the Environment and Your Wallet
If you’ve seen a bright white roof on a commercial building then you may have seen a TPO (thermoplastic polyolefin) roofing system. This popular commercial roofing system is great at saving energy for a single-ply membrane and is easy on the environment.
The term ‘thermoplastic’ refers to synthetic substances that get soft upon heating and harden when the heating stops. Expert roofers know that a TPO seam is four times stronger than EPDM seam.
The Key Benefits of TPO Roofing
TPO is a preferred system of commercial roofing in Dallas and is popular partly due to its ability to resist dirt, debris, bacteria, and algae build-up. This roofing system is also flexible, which makes it incredibly resistant to tears and punctures. This same quality makes it able to flex with the natural movement of commercial buildings.
If you have a hot-air welded seam, you can expect a much higher lifespan. They are much stronger than tape seams and EPDM adhesive.
White TPO roofs have solar reflective properties that help to reduce energy waste originating from HVAC systems. This also helps to minimize the heat island effect that usually makes life uncomfortable in many urban areas. As a result, the roof helps to create the desired cooler interior temperatures. Given that TPO is also recyclable, it remains the perfect, environmentally friendly roofing material.
The reasonable cost of TPO roofing systems is another critical factor that makes it attractive in commercial construction. Its installation process is less labor-intensive. Due to this, installing new TPO roofs or replacing them is several times less than many other roofing systems.
Our Affordable TPO Roofing Installation
At KSI Commercial Roofing Dallas we always follow the recommended procedure to install TOP roofs. We prepare the existing substrate. This involves either removing or cleaning the roof. After making the substrate ready, we install the insulation.
Our clients choose from the following types of insulation:
Expanded Polystyrene (EPS): EPS is highly valued due to its favorable R-value per dollar. The value makes it suitable for roof insulation.
Polyisocyanurate (Polyiso): Polyiso is the most popular insulation type. Even though it is expensive, many people choose it for its high R-value rating.
Extruded Polystyrene (XPS): The pink, green, and blue colors usually identify XPS. This type of insulation fall in-between EPS and Polyiso in the range of performance as well as price.
TPO roofing installation methods vary.
The fastening system makes use of fastening plates that ensures the membrane is firmly secured. It provides faster installation but does not use seam tapes or adhesives. Once the membranes are fastened, their seams are heat-welded using specialty hot-air equipment.
Mechanically attached roofing systems may have up to a 25 year warranty.
The fully adhered roof installation option firmly adheres and secures the membrane to the recovery or insulation board using TPO bonding adhesive. In this case, experts do not require fastening plates. The final stage involves heat-welding the membrane seams with specialty hot-air equipment.
These systems may carry up to a 30 year warranty.
A ballast roof system, as the name suggests, is ballasted throughout with gravel. It is also not anchored to the decking. Ballasted is the least used method for installing TPO membranes today.
How to Prevent Further Damage to Your TPO Roof
Professionals of commercial roofing in Dallas TX find that TPO is durable and typically lasts between 15 and 20 years. During this period, the membranes can get punctured. Seams can rip apart, and flashings can fail. If you do not act promptly, this can result in a severe roof leak.
To avoid experiencing these problems, you need to know the initial signs of a TPO system requiring repair.
The first sign is when water begins to enter the building. This is often an indication that a seam has separated.
The insulation can take on a lot of water, and when it is too much, it begins to enter the roofing deck. Eventually, it starts leaking in the interior of the building. Once you notice this, call a trusted TPO roofing contractor to inspect the system.
