(1) Many roofing contractors are known to abandon their customers when the contractor delivers poor quality, resulting in an inordinate amount of call-backs for corrections. Be sure to find a well-established roofer to avoid this problem. Every roofing company is different, offering different levels of value, service and quality of workmanship.

(2) When comparing proposals from various contractors, make sure the offerings (scope of work) are the same (an apples-to-apples comparison).

(3) Only contract with roofing contractors that have all of the proper insurance (general liability and workers' compensation). Request written proof and call their insurance company to verify the validity.

(4) Roof ventilation is critical. Pay attention to proper ventilation as it can be just as important to the overall life of your roof as the materials.

(5) Only use roofing contractors that use reputable materials by name-brand manufacturers with extended iron-clad warranties.

(6) Try to minimize roof traffic, especially where other contractors are concerned. Often, other contractors may damage roofs while working on them. For example, do not allow a cleaning contractor to use any type of bracing on pitched roofs where they might nail into your roof, therefore compromising your roof with a puncture through the protective roofing barrier.

(7) Weather is a factor when replacing your roof. Before the contractor approaches the tear-off of your roof, ask him what their plans are if stormy weather approaches in the middle of the removal or installation of your roof.

(8) Before paying any contractor, get a material and labor lien waiver. This will protect you against the contractor’s suppliers and workers coming to you for payment due from the contractor who has failed to pay them. Without this lien waiver, you may end up paying for your roof twice.

(9) Keep gutters clean and debris off the roof to allow efficient flow of water from the roof surface.

(10) Get all guarantees, warranties and promises in writing.

(11) Work with a contractor that has proven its integrity in the community. Once the roof is installed, you are stuck with the level and quality of installation for the next 15 to 25 years.
