A Proven Flat Roofing System for Long-Term Protection
If your building has a low-slope or flat roof, Modified Bitumen roofing offers a powerful combination of flexibility, durability, and water resistance. Originally developed as an advanced version of traditional
Built-Up Roofing (BUR), modified bitumen systems are engineered to stand up to San Diego’s heat, sun, and seasonal rain while delivering long-lasting performance.
What Is Modified Bitumen Roofing?
Modified bitumen is an asphalt-based material enhanced with rubber or plastic modifiers (such as SBS or APP) to improve flexibility and strength. These membranes are layered over a base sheet and sealed together to form a durable, waterproof barrier — typically installed using heat, cold adhesives, or self-adhering techniques.
It's a go-to solution for buildings where moisture resistance, strength, and ease of maintenance are top priorities.
Key Benefits of Modified Bitumen Roofing
Property owners in San Diego choose modified bitumen for its ability to perform in challenging environments. Here's why it's one of the most trusted systems for flat and low-slope roofs:
✅ Outstanding Waterproofing – Keeps water out with multi-layer protection
✅ High Tensile Strength – Withstands foot traffic, weather, and movement
✅ Thermal Efficiency – Reduces heat transfer, helping regulate indoor temps
✅ Versatile Installation – Can be applied via torch-down, cold adhesives, or peel-and-stick systems
✅ Cool Roof Options Available – Reflective top layers reduce solar heat gain
✅ Fire, Wind, and Hail Rated – Can be part of a rated and certified roofing system
✅ Cost-Effective Lifecycle – Low maintenance and long-lasting value
✅ Flame-Free Installation Options – Ideal for sensitive sites where open flame is not permitted
✅ Manufacturer Warranties Available – Protect your investment for the long term
Where Modified Bitumen Performs Best
This system is ideal for:
•Commercial buildings
•Retail centers
•Apartments and multi-family complexes
•Low-slope residential homes
•Warehouses and industrial structures
Whether you own a small business or a large facility, modified bitumen provides the durability and energy efficiency your flat roof needs.
Energy Savings & Climate Resistance with Torch Down Roofing
San Diego’s combination of UV exposure, warm summers, and occasional rainstorms demands a roofing system that’s tough and resilient. The multi-layer design of modified bitumen helps minimize heat transfer , reducing stress on your HVAC system and lowering cooling bills.
Combined with reflective surfacing, it qualifies as a cool roofing system, helping meet energy codes and improving occupant comfort.

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?
