How To Understand Cooperative Purchasing And Its Benefits

To understand Cooperative Purchasing, think of taking a hike on an unknown trail. The path is marked, but having an experienced trail guide is so, so much better. When you tap into the power of Cooperative Purchasing, Vanguard Roofing and Duro-Last® work together to guide you through it. They are there for you at the beginning and end of five simple steps to deliver a beautiful new roof. 

What is Cooperative Purchasing?

Say you work in a municipality, non-profit business, educational entity, or government agency and you need a new roof. You struggle every day with diminishing budgets. How much easier would your work be with the power of a cooperative group behind you? 

The Interlocal Purchasing System (TIPS) is a national purchasing cooperative leveraging the purchasing power of governmental entities in every state. If your organization is one of the 90,000+ eligible entities, you can let TIPS bid and award contracts to vendors under procedures mandated by state procurement regulations affecting your organization. 

Suppose your facility needs a new shingle roof. You can access the vetted and approved contract already in force with Duro-Last® to get a safe, long-lasting, sturdy new roof at an extremely low price. 

Better, by using the Cooperative Purchasing power of TIPS, your group is assured your contract, vendor, installer, and materials all comply with every applicable state and federal regulation. No unpleasant surprises! You save time, money, and worry.

Still better, your entity can rely on an expedited contract procurement process. Duro-Last®’s streamlined roofing project management abilities allow you to concentrate on your daily responsibilities of ensuring a safe, dry, and comfortable environment, leaving the contract details to TIPS.

The Cooperative (TIPS) conducts the meetings, issues all the requirements, and negotiates terms with the vendor, Duro-Last®. Then Duro-Last®, as the vendor, reviews and evaluates proposals. It then partners with Vanguard Roofing to have Vanguard complete the job.

This one-stop approach streamlines procurement and standardizes excellence. TIPS delivers products and services of the highest quality at the lowest possible cost to eligible entities.

Strategic Partners

Duro-Last® is one of the largest roofing manufacturing companies in the world, but it does not have a fleet of trucks and barracks full of roofers waiting for your call. Whether under a Cooperative Purchasing contract or otherwise, Duro-Last® turns to local roofers to get the job done. 

Duro-Last® is picky. It only partners with commercial roofers who demonstrate superior installation techniques and superb customer service. Duro-Last, Inc. is known for the “World’s Best Roof®.” It is the world’s largest manufacturer of custom-fabricated, thermoplastic, single-ply roofs.

Vanguard Roofing is proud to be the strategic partner for Duro-Last® in TIPS. Vanguard Roofing initiates and finishes the entire TIPS process, a simple five-step procedure for getting one of the finest roofs available anywhere. 

The path from planning for your new roof to the finished roof is Vanguard to TIPS to Duro-Last and then back to Vanguard Roofing for professional commercial roof installation

Five Steps

Perhaps you are a facilities manager for a municipal agency or non-profit group. You know you need a new roof (whether low-slope or steep-slope, Vanguard and Duro-Last® can handle it!). You turn to Vanguard Roofing, and we do the rest:

  1. Vanguard identifies the roofing need with your organization
  2. With our strategic partner, Duro-Last®, we design a roofing solution and deliver it to TIPS
  3. TIPS reviews the proposal and performs a compliance review to confirm the pricing is compliant with their contract
  4. The proposal is issued to your organization
  5. The project is executed by Vanguard Roofing, using Duro-Last® products


Duro-Last® has a factory-controlled fabrication system which can eliminate up to 85 percent of field seams, meaning there are fewer places for water to penetrate your roofing system for your organization’s new roof under TIPS.

Since most Duro-Last roofs are custom-fabricated, the fabrication system lowers labor and installation time and costs. The company’s system is ideal for any flat or low-sloped applications, including solar-ready roofs.

Under the TIPS contract, other types of roofs for churches, schools, courthouses, and emergency service buildings can be installed:

  • Fiberglass-asphalt shingles
  • Slate roofing
  • Low-slope
  • Steep-slope
