Your roofing contractor should be able to give you the contact information of a supervisor to talk to in case of any issues.
Hiring a contractor
Here are some things to when you are looking to hire a contractor.
Make a list of exactly what you want done. Remember that changing plans in the middle of a project will cost extra money. Set a clear budget. Ask for recommendations from friends and neighbours.
Consider dealing with a local company. This may make it easier to check references, enforce a warranty or have follow-up work done.
Get written estimates from at least three contractors.
Never accept an estimate over the phone or without the contractor inspecting the area.
Remember that good contractors ask a lot of questions so they can understand and plan out the project. For example, in driveway paving, they should ask if any heavy vehicles will be parked on the driveway.
Don’t go for a deal that sounds too good to be true.
If it’s a major project, you might need an architect or engineer to draw up plans and give direction. You will also likely have to get a building permit. Ask your town hall how much building permits cost and how to get them.
Check out your references, even if someone you know has recommended the contractor to you. Make sure each reference is from someone who has dealt with the contractor personally.
Get references from people who had work done that is similar to the project you have in mind.
Also, get references both from the recent past and further back in time. Sometimes, problems do not show up for a while. For example, you often don’t see problems in roofing or paving for about a year or more after a project is done.
Check warranties and guarantees carefully. But remember that the contractor’s reputation and length of time in business are more important than a warranty or guarantee.
Avoid cash deals. Reputable companies meet all legal requirements, like charging and paying applicable taxes. If you do pay in cash, make sure that you get a detailed, signed receipt from the contractor.
If a contractor offers you financing, it may be wiser to arrange your own.
