Here at B&L Roofing, we know that Colorado’s extreme weather, from blazing summer sun to heavy winter snows, demands a commercial roof that can stand up to the elements. Recently, our crew headed out to West 5th Ave to tackle a full TPO (Thermoplastic Polyolefin) roof replacement. TPO is one of the most popular commercial roofing options today, known for its energy efficiency, durability, and seamless waterproofing capabilities.

Here is a behind-the-scenes look at how our expert team meticulously rebuilt this roof from the deck up.

Step 1: Understanding the Foundation

A high-quality roof is more than just the top white layer; it is a carefully engineered system. Before rolling out the new membrane, we had to ensure the underlying structure was perfectly prepped and insulated.

Step 2: Safety First

At B&L Roofing, safety is our top priority. Before any heavy lifting or installation begins, our crews establish strict safety perimeters. Working at heights requires constant vigilance, especially when moving large materials across a sprawling commercial rooftop.

Red warning flag lines are set up along the perimeter of the West 5th Ave roof. These visual barriers keep our crew safe and maintain a secure working distance from the leading edge while they navigate the vast workspace.

Step 3: Securing the Substrate

With safety measures in place, the crew got to work laying down the rigid insulation and cover boards. This layer is crucial—it provides the R-value needed to keep the building energy-efficient during harsh Colorado winters, while also giving the TPO membrane a smooth, rigid, and impact-resistant surface to rest on.

The B&L Roofing crew hard at work mechanically fastening the insulation and cover boards. Each board is secured to the metal deck below using specialized heavy-duty screws and distribution plates to ensure maximum wind uplift resistance.

Step 4: Rolling Out the TPO Membrane

Once the substrate is fully locked down, the star of the show makes its appearance. The crew begins rolling out the bright white TPO membrane. The highly reflective surface of TPO is excellent for reducing a building’s cooling costs by reflecting the sun’s UV rays away from the structure.

Our roofers unrolling the wide sheets of TPO membrane across the newly prepped surface. The sheets are carefully aligned before being mechanically attached and heat-welded at the seams to create a single, monolithic watertight barrier.

Step 5: Precision Fastening at the Perimeters

A roof is only as strong as its weakest point, which is usually the edges. The perimeters of a commercial roof endure the highest wind uplift forces. To ensure this roof stays put during severe Colorado windstorms, our team pays special attention to the detailing and fastening along the edges.

A B&L Roofing technician uses a heavy-duty drill to mechanically fasten the system near the roof’s edge, working right alongside our safety lines. This meticulous perimeter work ensures the new roof is locked in tight against the elements.

 

Another Job Well Done By the time the final seam was heat-welded, the property on West 5th Ave was protected by a state-of-the-art, energy-efficient roofing system designed to last for decades.
