Get at least three estimates before deciding on a roofer. This is still your best defense against unjustified high prices. Carefully examine the type of materials and the length of the warranty. Obviously, I hope that LeakMaster is one of the contractors that you choose to give you an estimate. The Hawaii Roofing Contractors Assoc. is made up of a group of reputable, licensed contractors who generally subscribe to the higher principles of our profession.
Unlicensed contractors are cheaper than licensed ones.
They almost never come back to repair their leaky work. They don't pay for insurance in case their worker gets injured on your property. So you can be sued. It's a dangerous business. Yearly maintenance can also extend the life of your roof.
