Find a contractor who has experience in house framing. A flat roof can increase the load weight on the roof during times of heavy snow. A flat roof is less likely to shed off snow and water and can therefore become much heavier than other roofs. If your contractor has experience in framing, then he or she will be more able to provide you with the stability you need in the roof.

Get estimates from a lot of different contractors before you hire anyone. This will allow you to compare the pricing structures of many different contractors before you agree to work with anyone. You may even be able to use the estimate from one contractor to bring down the bid from another contractor.

You should only hire contractors who are able to give you references from previous clients. Most experienced contractors will have enough client references for you to get a good idea of how the contractor works. These references will tell you about the skill and the attitude of the contractor before you hire anyone.
