Commercial TPO Roofing In Raleigh, NC

Commercial TPO roofing is a single-ply roofing membrane system that has been improved for ductility and impact resistance. A TPO roof is also known as thermoplastic Polyolefin or “cool roof”. TPO membranes are made up of three layers: TPO polymer base, polyester-reinforced fabric center, and a thermoplastic polyolefin compounded top.

TPO roofs are single-layer synthetic and are mostly used as a commercial roofing solution for flat-topped buildings. Because of their budget-friendly price and high adaptability, these so-called “cool roofs” are one of the most popular commercial roofing systems available today.

Furthermore, TPO is a lightweight material. Our roofing installation crews can quickly deliver your commercial roofing materials without the use of scaffolding. As a result, we can complete your roofing installation quickly with a smaller team than it typically needs with other types.

Installing TPO roofing For Commercial Use

Commercial TPO installation consists of multiple key steps that should be followed by an expert roofing company.

Preparing the Roof

Commercial TPO installation may include taking out the current commercial roofing system while attaching insulation and cleaning the substrate. The roof is prepped by making sure that it is dry, clean, and free from any sharp or pointed projections that could rip the membrane. Applying cant-strips are crucial if two surfaces meet at a right angle.

Applying Insulation

During commercial TPO installation, insulation is applied to enhance energy efficiency and to prevent water vapor from harming the membrane. If the surface is fastened using urethane adhesive, insulation is attached mechanically using nails. Steeped roofing asphalt over primed structural concrete decks is a favored choice for certain types of commercial TPO roofing. If the slope of the roof surpasses an exact threshold, wood nailers could be added throughout the perimeter.

Setting the Cover Board

In a commercial TPO roofing installation, a cover board, commonly 5″ plywood or OSB, will be set on top of the insulation and serves where the membrane will be installed. During this stage, sharp edges on the boards are to be smoothed down. At this point, separator sheets, made from fiberglass or polyester can then be attached.

Membrane Installation

The membrane is later attached using mechanical fasteners, a ballasting system, or a bonding adhesive. Wrinkles and buckles should be prevented by properly laying the membrane. To avoid air bubbles and movement, the adhesive should be put on the membrane’s whole surface area. This procedure involves applying adhesive to specific areas of the membrane. The perimeter areas of the commercial roof will be covered with half sheets and off-cuts.

Fastening The Membrane

The side lap sections are then secured into place mechanically using fasteners and plates. The seams are sealed using a hot air welding machine or a hand welder and silicone roller once the membrane has been entirely spread out. To guarantee a complete seal of the membrane, all seams must be examined and make necessary repairs.

Drainage Control

When it comes to commercial TPO roofing, properly setting up the drainage is one of the most crucial steps. Drip edges are added in the last stage to lead water to the gutter system and avoid the roof from developing leaks and holding water. All areas of the roof where the membrane overlaps are joined using T-joints.

Flashing is done on walls and curbs as a measure of guiding water flow around parts of the commercial roof that are prone to leakage.
