What are the relevant warranties?

Roofing materials will come with product warranties. But you should also inquire about whether the contractor guarantees the labor and installation itself. Reputable roofers will stand behind their work with a labor warranty.

How long will the job take?

The contractor should not only give you a timeline for the project’s completion, but also outline his policy for weather-related delays. Also, find out if the contractor will start on any other jobs before your roofing project is completed.
