Commercial roofing is one of the most demanding areas of expertise in the roofing industry, and there are hundreds of unique roofing systems and variations of application.When it comes to commercial roofs, there are three main types of roofing systems: single-ply roofing, built-up roofing, and modified bitumen roofing.

2. 1. Single-Ply Roofing:
This is made of a variety of plastics and rubbers
such as ethylene propylene diene monomer
(EPDM), thermoplastic olefin/polyolefin (TPO),
and polyvinyl chloride (PVC).

3. 1. Single-Ply Roofing:
These are single-layer applications of roofing
sheets bonded along the seams with a heat or
adhesive.

4. 1. Single-Ply Roofing:
Single-ply systems are ideal for areas that are
exposed to direct sunlight.

5. 2. Built-Up:
Built-up systems offer layers of reinforcements,
because of the way the layers are sandwiched
together.

6. 2. Built-Up:
Built-up roofing is made of multiple layers of felt
and molten asphalt, and often covered with roll-
roofing cap-sheet.

7. 3. Modified Bitumen:
This type is comprised of a felt based sheet that
is covered with a modified bitumen cap sheet,
which is made of reinforcement coated asphalt
combined with plastic or rubber to strengthen
the bitumen and make it tear-resistant.

8. 3. Modified Bitumen:
The modified bitumen is covered with an
aluminum-rich paint or granules for enhanced
sun protection.
