Industrial Strength. Seamless Waterproofing.
Time-Tested Resilience. Multi-Ply Protection.
The Gold Standard of
Commercial Durability.
For facilities that require the absolute highest level of puncture resistance and redundant waterproofing, Hot Mop roofing (traditionally known as Built-Up Roofing or BUR) remains the premier industrial choice. This system is constructed on-site by layering bitumen (hot asphalt) with reinforcing fabrics to create a thick, resilient, and seamless roofing “sandwich.”
The primary advantage of a Hot Mop system is its redundancy. While single-ply roofs rely on a one-layer membrane, a Hot Mop system utilizes multiple plies. If the top layer is damaged, the underlying layers continue to provide a reliable defense, ensuring your operations remain dry and protected.
At Achilles Roofing & Exterior, we maintain the specialized equipment and expert crews necessary for high-heat applications. We manage the logistics of kettle placement and temperature control with precision to deliver stone-solid security for your building’s roof deck, all backed by our 5-year workmanship warranty.

- Seamless: Fuses into one solid, monolithic mass.
- Tough: Withstands heavy traffic and maintenance.
- Fire-Safe: Naturally resistant to fire spread.

Great price · $2,000–4,000
To cool down my attic, I decided to install a solar attic fan. I got proposals from four different vendors and evaluated them based on customer service, experience, implementation, and price. Achilles Roofing & Exteriors, led by Ahmad Faiz, was the standout choice.

Ahmad is very professional. The process was very simple. Price was affordable and the quality of work is amazing. Thank you for the new replacement and previous rook repairs.
Quick turnaround on some roof repairs we needed for the sale of our home. Everything was documented on the invoice and with photos. Very professional.
Great job on my Atrium cover. Used them before for my roof. Well done and very reasonable.
