When choosing a roofing system for your home, the factors you should consider are Weight, Durability, Fire-Rating, Appearance and Cost. The appearance you want from your roof and what your budget can afford should be determined before you start shopping. Also, know what type of structure your home has. This will determine how much weight the structure can hold and whether it will be necessary to reinforce or apply plywood before the new roof application.
When considering the durability of a material, check to see what kind of manufacturer’s warranty is offered and what type of warranty the contractor will offer. Remember, the warranty offered is only as good as the manufacturer or contractor who stands behind it.
