When looking for a contractor for flat, foam or single ply roof repairs, you should find someone who has the business infrastructure required to do work on this scale. While this type of roofing can be long-lasting and energy efficient, it is also more difficult to apply. The contractor you work with should have a team of at least four people who can help him or her with the repairs. The machinery required for the application of foam roofing material may require special licensing and permits depending on applicable state laws.

You also want to be sure that you have a contract in place with any contractor you work with on a roofing job like this. The contract should state how much the job is estimated to cost, it should state how long the job is estimated to take and it should clearly list payment terms. When it comes time to look over the contract, you shouldn't be shy about asking for additions or changes. You are an equal part of the agreement and you should have your own say. If you find that there is something in the contract that you're not comfortable with, bring this up with the contractor.
