Benefits of Modified Bitumen Roofing
Finance and Insurance Claim options
Types of Bitumen Roofing
APP (Atactic Polypropylene) Modified Bitumen
This type of Mod Bit roofing is modified with plastic (APP) polymers, making it more resistant to UV radiation and suitable for torch-applied installations.
SBS (Styrene-Butadiene-Styrene) Modified Bitumen
Modified with rubber (SBS) polymers, this type offers superior flexibility and is typically installed using cold adhesives or hot asphalt.
Modified Bitumen vs. Other Flat Roofing Systems
Modified Bitumen Vs. Built-Up Roofing (BUR)
Durability: Both systems are durable, but Mod Bit typically offers better flexibility and resistance to thermal shock.
Installation: Mod Bit is generally easier and quicker to install compared to the labor-intensive process of installing BUR.
Maintenance: Mod Bit roofs often require less maintenance than BUR systems, which can be prone to gravel displacement and membrane separation over time.
Cost: While both are cost-effective, Mod Bit can be more economical due to its simpler installation process.
Modified Bitumen Vs. Single-Ply Roofing (EPDM, TPO, PVC)
Durability: Mod Bit and single-ply systems both offer durability, but single-ply systems may offer superior resistance to certain chemicals.
Energy Efficiency: Single-ply membranes like TPO and PVC often have excellent reflective properties, but Mod Bit with reflective coatings can also achieve significant energy savings.
Flexibility: Mod Bit offers flexibility in varying temperatures, while EPDM can become brittle in cold weather.
Installation: Single-ply systems are typically faster to install, but Mod Bit’s torch-applied or self-adhered options can streamline installation while offering robust performance.
Modified Bitumen Vs. Spray Polyurethane Foam (SPF)
Durability: Both provide durable roofing solutions, but Mod Bit may have an edge in puncture resistance.
Maintenance: SPF roofs require periodic recoating, whereas Mod Bit roofs typically require less frequent maintenance.
Cost: Mod Bit is generally more cost-effective upfront compared to SPF, which can be more expensive due to the specialized equipment and expertise required for installation.
When to Replace Your
Modified Bitumen Roof
Visible Wear and Visible Cracks and SplitsAccordion Heading
Inspect the surface for any visible cracks or splits, which can indicate that the material has aged and may allow water infiltration.
Blistering or bubbling
Blistering occurs when trapped moisture or air causes raised bubbles under the membrane. Left untreated, it can lead to leaks and membrane damage—prompt repair is essential to maintain roof integrity.
Discolouration or UV Damage
Prolonged sun exposure can cause fading, cracking, or surface deterioration on modified bitumen roofs. UV damage weakens the membrane over time, reducing its effectiveness and lifespan—early inspection and treatment are key.
Ponding Water
Standing water that remains on a flat roof for over 48 hours can lead to membrane damage, leaks, and structural stress. Proper drainage and timely repairs are essential to prevent long-term issues.
Age of the roof
As modified bitumen roofs age—typically after 15–20 years—they become more prone to cracking, leaks, and weather damage. Regular inspections help determine when repairs or full replacement are needed.
Frequent repairs
If your roof needs constant fixes, it may signal deeper structural issues or nearing end-of-life. Repeated repairs can add up—making a full replacement a more cost-effective, long-term solution.

Our Customers
Unfortunately, after following up several times to schedule the repair, I was told by text, “Boss said no.” Not only was the job now off the table, but during the original visit, part of the chimney had been pulled apart without my consent — leaving it more exposed than before. When I raised this concern, I received an initial response from their COO, who apologized and said he would look into it. Despite my attempts to follow up and work toward a solution, they stopped responding entirely.
I don’t take leaving negative reviews lightly, but this was a disappointing experience. I was left with a partially dismantled chimney, no resolution, and empty assurances. I hope others have a better experience, but I can’t recommend this company based on how things were handled in my case.
We recently had our entire roof redone by AZ Roof Co., and I couldn’t be happier with the results. The new roof looks fantastic, and it’s backed by a 20-year warranty, which gives us so much peace of mind.
A huge shoutout to Pino, our Project Manager—he was truly a pleasure to work with. He was incredibly accommodating with our schedule, kept us informed every step of the way, and was always kind and professional. You could really tell he cared about the quality of the work and our overall experience.
There was a small mishap during the project where something fell and damaged one of our outdoor tables, but I want to emphasize how impressed I am with how the team handled it. They immediately took responsibility and are going above and beyond to make it right. That level of accountability and customer care is rare and very much appreciated.
I highly recommend AZ Roof Co. to anyone in need of roofing work. Excellent service, beautiful results, and a team that truly stands behind their work!
