Expert Modified Bitumen
Roof Installation & Repair

Modified bitumen is a rugged, multi-ply roofing system built for durability and strength. Made of asphalt-based membranes reinforced with polymer modifiers and applied in layers, it offers excellent resistance to foot traffic, punctures, and the temperature extremes common to Denver’s climate. That toughness makes it a popular choice for roofs that see regular maintenance access or heavy wear. Premier Restoration & Construction installs, repairs, and maintains modified bitumen roofing across the Denver area as part of our full commercial roofing services, helping you choose the right system for how your building is actually used.

Fast & Friendly Service
Industry Best Practice Inspection Techniques
Honest & Transparent Estimates
Qualified & Professional Technicians

The multi-layer design of modified bitumen makes it durable, but seams, flashings, and the top layer still need attention over time. A routine commercial roof inspection catches wear early, and most problems are resolved with a targeted roof repair. When the system reaches the end of its life, we provide a full roof replacement matched to your building’s needs. Deciding between systems? Compare modified bitumen with TPO and EPDM to weigh durability, cost, and energy performance side by side.

Commercial Bitumen Roofing FAQs

Modified Bitumen Roofing Frequently Asked Questions

At Premier Restoration & Construction, we’ve completed hundreds of Modified Bitumen roof installations and repairs across the Denver metro area—and we understand the questions commercial property owners ask most. Our team is here to help you make informed, confident decisions about the best roofing solutions for your building’s long-term performance and protection.

What is Modified Bitumen roofing?

Modified Bitumen (Mod Bit) roofing is a durable, multi-layer asphalt-based system designed for low-slope and flat commercial roofs. It combines traditional asphalt roofing with modern polymer technology, enhancing flexibility, strength, and weather resistance. Commonly reinforced with fiberglass or polyester, Mod Bit roofs perform exceptionally well in Colorado’s variable climate, standing up to snow, hail, and intense UV exposure.

How does Modified Bitumen compare to TPO and EPDM roofing?

Each roofing system offers distinct benefits:

Modified Bitumen: Extremely durable, puncture-resistant, and ideal for roofs with heavy foot traffic or equipment.
TPO: Lightweight, reflective, and energy-efficient—best for hot, sunny climates.
EPDM: Highly flexible and cost-effective, performing well in cold weather.

For Denver’s climate, Modified Bitumen is often preferred for multi-story buildings, warehouses, and facilities needing long-term toughness and easy repairability.

How do I maintain a Modified Bitumen roof?

Regular maintenance ensures your roof continues to perform at its best. Recommended care includes:

Semiannual inspections (spring and fall).
Checking seams, flashing, and drains for wear or blockages.
Cleaning and re-coating reflective surfaces as needed.
Repairing minor damage immediately to prevent water intrusion.

Premier Restoration & Construction provides scheduled maintenance plans designed to preserve warranty coverage and maximize your investment.

  Jake and his team were great with the water damage assessment, the window frame/trim repair, drywall repair, and full resealing of all of our exterior windows. Fair quote, showed up on time, clear communication, and went above and beyond with pictures and details of what they found and exactly what was fixed. I'll be a repeat customer in the future.

  5 stars — Great work, fair price, and a clean job site
We had our roof replaced after storm damage from last year and couldn’t be happier with the experience. The crew showed up on time, worked efficiently, and finished the job in a day and a half as promised. They walked me through the whole process upfront — materials, timeline, and cost — with no surprises on the final bill.
The workmanship is excellent and they took the time to make sure everything was done right. They also did a thorough cleanup at the end, which I really appreciated since they had to work around our landscaping. Communication was great from the initial estimate through the final walkthrough, and they even handled the insurance paperwork side of things for us.
If you’re looking for a reliable roofing company that does quality work at a fair price, I’d definitely recommend giving them a call. We’ll be using them again if we ever need any other work done. Thank you Jake Taton.

  These guys where awesome we had a roof damaged hired another contractor Top Tier Roofing that took a 10k deposit and after over year still no roof. We were lucky and was able to find these guys. After we told them what happened they did  the job basically at cost to help us out. I spoke on the phone Jake came out the next day gave estimate, we approved it couple days later the materials got  delivered. The next day the job was done and past inspection. I would highly recommend these to anybody. Thanks again Jake
