What Is Modified Bitumen Roofing?
Modified bitumen torch down roofing is a durable, time-tested flat roofing system commonly used on commercial buildings and low-slope residential roofs. It's known for its strength, weather resistance, and long-term performance—especially in areas with intense sun, wind, or rain.
How It Works:
This system uses rolls of modified bitumen (a type of asphalt reinforced with rubber or plastic) that are applied to the roof surface using a propane torch. The heat melts the underside of the material, bonding it tightly to the base layer and forming a waterproof seal.
Key Benefits:
Waterproof Protection – Torch down creates a seamless, watertight layer that resists leaks.
UV Resistance – The surface can reflect sunlight, reducing heat absorption and improving energy efficiency.
Flexibility – Modified bitumen expands and contracts with changing temperatures, reducing the risk of cracks.
Long Lifespan – With proper maintenance, these systems can last 20+ years.
Key Benefits of Modified Bitumen Roofing
Modified bitumen is a trusted roofing solution for flat and low-slope properties, thanks to its performance in demanding conditions. This system provides excellent waterproofing through its multi-layer protection, helping to keep moisture out even in heavy rain. It's built with high tensile strength, allowing it to withstand foot traffic, weather shifts, and building movement without compromising integrity.
Property owners also appreciate its thermal efficiency, which helps reduce heat transfer and regulate indoor temperatures. Installation is versatile—whether it’s torch-down, cold adhesive, or peel-and-stick, there’s a method suited for every project. Reflective surface options are also available, offering a “cool roof” benefit that minimizes solar heat gain and enhances energy savings.
In addition to being fire, wind, and hail rated, modified bitumen systems offer a cost-effective lifecycle with low maintenance needs and long-term durability. For sensitive environments, flame-free installation methods are an option, making it a safe and flexible choice. Many systems also come with manufacturer warranties, offering added protection for your investment.

•Commercial buildings
•Retail centers

I recently had an urgent roofing issue brought to my attention by the heavy rain we recently experienced. Near our chimney there was water somehow leaking inside and reaching the drywall. We called Titan Roofing and were blown away by their prompt response and professionalism.
Their team arrived on time and worked efficiently to remove all the roof tiles in the area, strip the underlayment, and found the wood rot issues with the plywood. They then replaced the plywood, used a sealer, replaced the underlayment, and added the roof tiles back in place. My wife is a bit picky when it comes to the home aesthetics, but Titan Roofing even made sure we were completely satisfied before they left.
The team was knowledgeable, courteous, and provided a fair and transparent estimate. I was also impressed with the care they took to protect my property and clean up debris after the job was done. I highly recommended Titan Roofing for any roofing needs, big or small.

If you are reading this, that means you are looking for a great roofer! Titan Roofing owned by Andrez Lopez is incredible! We've done quite a bit of remodeling at our home and contractors were all over the map with bids and credibility.
I researched six large and small companies from Angis list and Home advisor. One company came out and said "I'll look at your roof from a satellite view and give you bid in a few days! Huh?!
Andrez, the owner of Titan Roofing was the ONLY owner who walked up ON THE ROOF himself, told us what was needed, and then said that we needed to replace our bathroom vents and fireplace spark arrestors! And that was in the first 20 minutes! We paid him to come back and replace those items!
We cannot be happier! I'm kind of a hard ass, but when I realized how great Andrez' Titan Roofing was, we hired them. They are far above the other roofers we interviewed! His bid was $5000 less that three other bids, and get this: He also replaced all of the bad facia, and installed new rain gutters!
So, what will you get with Titan Roofing?
