Indiana’s Commercial Roofing Experts

When it comes to commercial roofing, there’s no “one-size-fits-all” solution. The right system depends on your building type, budget, energy goals, and how you plan to use the space. At Discount Roof, we help you choose the best option—and install it the right way—so your roof performs for decades, not just a few seasons.

Duro-Last® Roofing

Duro-Last is a premium commercial roofing system known for its long-term durability and precision fit. Because much of the material is custom-fabricated, seams are minimized, installation is faster, and the finished product is extremely watertight.

Great for: warehouses, schools, retail buildings, and large flat-roof facilities
Why building owners love it:

• Custom-fit panels for fewer seams and fewer leak points

• Highly reflective white membrane can lower cooling costs

• Strong resistance to punctures, chemicals, and harsh weather

• Proven track record for long-term performance

If you want a low-maintenance roofing system with excellent lifespan and reliability, Duro-Last is one of the strongest commercial options on the market.

TPO (Thermoplastic Polyolefin)

TPO is one of the most popular modern flat-roof materials because it balances affordability, energy efficiency, and durability. Its naturally reflective surface helps reduce heat absorption, which can lower HVAC strain and improve indoor comfort.

Great for: office buildings, retail spaces, and energy-conscious properties
Key benefits:

• Highly reflective membrane helps cut cooling costs

• Heat-welded seams create strong, watertight bonds

• Strong resistance to UV damage, algae, and chemicals

• Cost-effective option with long-term value

For commercial roofs that need performance without breaking the budget, TPO is often the best fit.

EPDM (Rubber Roofing)

EPDM is a time-tested commercial roofing system known for flexibility and weather resistance. It performs especially well in areas with wide temperature swings because it expands and contracts without becoming brittle or cracking.

Great for: buildings with heavy seasonal temperature changes, older structures, and flat roofs needing reliable durability
Advantages include:

• Excellent resistance to hail, wind, and thermal movement

• Long lifespan when properly installed and maintained

• Budget-friendly option with proven performance

• Easy to repair and maintain over time

EPDM is a dependable system for building owners who want long-term protection and straightforward upkeep.

Commercial Roof Coatings

Not every commercial roof needs a full replacement. In many cases, a professional roof coating can extend the life of your existing system and improve waterproofing, reflectivity, and overall roof performance.

Ideal for: aging flat roofs, minor leaks, and buildings wanting cost-effective life extension
Why coatings are smart:

• Seals small cracks and reinforces aging roof surfaces

• Improves reflectivity and reduces heat absorption

• Can add years of service life at a fraction of replacement cost

• Often installed with minimal disruption to daily operations

Coatings can be one of the most cost-effective options for commercial property owners—especially when applied before major damage occurs.
