Ice-and-water membrane and synthetic underlayment do different jobs. The membrane is the leak barrier at vulnerable details. Synthetic underlayment is the field deck sheet under the shingles. This comparison uses two official GAF examples: WeatherWatch leak barrier and FeltBuster synthetic roofing felt (FeltBuster sell sheet). Other brands differ. Warranty eligibility depends on the system and product; read the current manufacturer warranty and installation documents.
WeatherWatch and FeltBuster, as published
| WeatherWatch example | FeltBuster example | |
|---|---|---|
| Role | Leak barrier for vulnerable areas such as eaves, rakes, valleys, and around penetrations. | Field deck protection under the roof covering. |
| Nominal roll | 150 or 200 sq ft. | 1,000 sq ft, excluding laps. |
| Water | Ice-and-water leak barrier for those details. | Water-resistant, not waterproof. |
| Exposure | Follow the current installation document. | Not a temporary roof. |
| Fasteners | Follow the current installation document. | Plastic cap nails or staples, per the instructions. |
Worked roll counts (nominal, before laps, cuts, and waste)
- 300 sq ft of leak-barrier area = two 150-sq-ft WeatherWatch rolls, or two 200-sq-ft WeatherWatch rolls.
- 1,600 sq ft of field = two 1,000-sq-ft FeltBuster rolls.
These counts are nominal and they ignore laps, cuts, and waste. Round up and follow the actual deck dimensions and the current instructions. Local code varies, and the building official controls what is required. This page does not state a code rule.
What to put on the bid
- Leak barrier: product, nominal roll size, and where it goes (eaves, rakes, valleys, penetrations).
- Field sheet: product, nominal coverage excluding laps, and that it is not the temporary roof.
- Fasteners called out in the field-sheet instructions, including plastic cap nails or staples for FeltBuster.
- Drip edge sequence (drip edge and flashing guide).

Bottom line
Put WeatherWatch-class membrane on the vulnerable details and FeltBuster-class synthetic on the field. Warranty eligibility depends on the system and product; read the current manufacturer warranty and installation documents. The shingle warranty terms guide compares what GAF, Owens Corning, and CertainTeed publish. Then sketch the squares and round up.
Frequently asked questions
Does this page state a building-code requirement?
No. Local code varies, and the building official controls. Read the current product instructions and confirm the local requirement before you buy.
Can I use house wrap as roof underlayment?
No — use roofing-rated underlayment only.
How many rolls of ice & water do I need?
Depends on eave length and valley count — force the bid to show linear feet or a marked roof sketch.
