How to choose
- Insurer first. Some carriers keep a list of products they credit. Check it.
- Look and color. Most Class 4 lines come in the same colors as standard lines; HOA approval is usually easy.
- Warranty. Manufacturer warranty tiers depend on the accessories used. Residential warranty: a 10-year transferable workmanship warranty, with manufacturer warranties up to lifetime. Manufacturer coverage depends on the product and brand, and on the project qualifying for that manufacturer's program. We put the exact warranty for your roof in writing.
- Budget. Class 4 costs more than Class 3. If your insurer gives no meaningful credit, Class 3 may be the better buy.
