How is TPO Roofing Installed?
Learn how TPO roofing is installed step by step. Discover why this durable, energy-efficient flat roofing option is ideal for businesses.
TPO (Thermoplastic Polyolefin) roofing has become one of the most sought-after materials for commercial roofs. Why? Its energy efficiency, durability, and relatively simple maintenance make it an excellent choice for buildings with flat or low-sloped roofs.
But how is TPO roofing installed, and why should you consider it for your next roofing project, especially if you’re based in Wisconsin or Illinois?
Here’s an in-depth guide that covers everything you need to know about TPO installation and the advantages it offers.
What is TPO Roofing?
Before we get into installation details, it’s essential to understand what TPO roofing is. TPO is a single-ply membrane roofing material, commonly used on commercial buildings. It’s made of synthetic materials and reinforced scrim, offering both flexibility and strength.
Key Benefits of TPO Roofing
Energy Efficiency: Reflects solar heat, reducing cooling costs.
Durability: Resistant to punctures, tears, UV rays, and chemicals.
Wide Compatibility: Works for various building sizes and roof types.
Eco-Friendly: TPO is 100% recyclable, adding to its appeal.
If you’ve been looking for commercial roofing materials that can withstand the harsh weather conditions in Wisconsin and Illinois, TPO roofing is an excellent choice.
How is TPO Roofing Installed?
The process of installing TPO roofing involves multiple steps designed to ensure weather resistance and long-lasting performance. Here’s a closer look at what happens during a professional TPO roof installation.
Step 1: Preparation
Proper preparation lays the foundation for a smooth installation process.
Inspection: The existing roof is inspected for damage or structural issues.
Cleaning: The surface is cleaned thoroughly to remove dirt, debris, or remnants of old materials.
Old Roof Removal (if necessary): Any worn-out roofing layers are removed for a clean slate.
A flat and clean surface is crucial for adhering the TPO material effectively.
Step 2: Insulation and Cover Board Installation
Insulation is applied to improve thermal efficiency and regulate indoor temperatures. Common insulation materials include polyisocyanurate and expanded polystyrene.
On top of the insulation, a cover board is installed to provide a sturdy base for the TPO membrane.
This step is essential for creating a smooth and durable surface.
Step 3: Rolling Out the TPO Membrane
Once the surface is prepped, the TPO membrane is rolled out across the roof. These sheets come in varying widths, often reducing the need for seams.
The TPO material is laid out evenly, with minimal overlaps.
Edges are carefully aligned to avoid gaps that could lead to water leaks.
Step 4: Securing the Membrane
There are two main ways to secure the TPO roofing membrane to the roof structure:
Mechanical Fastening: Screws and plates attach the membrane directly to the roof deck.
Adhesive Bonding: Long-lasting adhesives are used to secure the membrane in place.
Step 5: Welding the Seams
This step is critical for ensuring the roof’s durability.
A hot air welder is used to heat and seal the seams between overlapping TPO sheets. This creates a watertight bond that prevents leaks and enhances the roof’s strength.
Each seam is inspected to confirm proper adhesion.
Step 6: Final Inspection
Once the TPO is installed, a thorough inspection is conducted to ensure proper fastening, seam welding, and overall integrity. Any missed areas are fixed immediately.
How Long Does TPO Roofing Last?
A properly installed TPO roof can last 15 to 20 years with regular maintenance. Factors like quality of installation, climate conditions, and maintenance routine play a significant role in its longevity.
For businesses in Wisconsin and Illinois, where winters are harsh and summers can be humid, routine inspections are vital for extending the lifespan of TPO roofs.
Advantages of Professional TPO Roof Installation
Attempting TPO roofing as a DIY project isn’t advisable. Working with professional TPO roof installers ensures that your investment yields the best results. Here’s why expert installation matters:
