About Polyglass
Polyglass: Experts in Membranes and Underlayments
Polyglass is part of the Mapei group and focuses on waterproofing. Its products show up under many roofs, not just on top.
- Polystick self-adhered underlayments stick to the roof deck and seal around nails.
- High-temperature Polystick types are made for use under metal and tile.
- Elastoflex is SBS modified bitumen, flexible in changing temperatures.
- Polyflex is APP modified bitumen, often torch-applied and very UV resistant.
On tile roofs, the underlayment does most of the waterproofing. Using a strong one is the best way to protect the home.

Install and care
SBS or APP: Which Polyglass Flat Roof Fits?
Both are modified bitumen, but they behave a little differently.
- SBS (Elastoflex) stays flexible and handles movement well.
- APP (Polyflex) resists strong UV and is usually torch-applied.
- Self-adhered sheets are a good pick when using a torch is not safe.
- A reflective cap or coating helps either one meet cool roof rules.

Polyglass questions
Polyglass Roofing Questions Answered
What Venice homeowners ask us about Polyglass products.
What is Polystick underlayment?
Polystick is Polyglass's self-adhered underlayment line. It sticks to the roof deck and seals around nails for strong protection.
What is the difference between SBS and APP modified bitumen?
SBS is rubber-modified and very flexible. APP is plastic-modified, very UV resistant and usually torch-applied.
Why use Polyglass under a tile roof?
Tiles shed most water, but the underlayment does the real waterproofing. A high-temp self-adhered sheet lasts much longer than basic felt.
Can Polyglass flat roofs go on without a torch?
Yes. Polyglass makes self-adhered modified bitumen that installs without open flame.
