To save money, should I be talked into using off-brand materials?
Never! Guarantees for most roofing work range between 10 and 20 years. Often during that time, firms go out of business. Building material suppliers tend to have longer track records. If you use name brand materials from major manufacturers (GAF, Owens Corning, Certainteed, etc.) you have a much better chance of recouping your losses should your new roof run into problems.
