Most homeowners may only have to fix their homes roof once or maybe twice in their lifetime.
This of course depends on long you own your home for and what kind of roof you have. Most home owners like to get 3 comparative quotes. However this is not always the case. Some home owners get multiple quotes and just get more confused when the prices start varying widely. There can be various factors for this such as company overhead, pay rates of employees, length of warranty, and type of materials being offered. This can often be resolved with a little home work and just asking your contractor some frank questions. The most important thing to consider is reputation and dependability. You can find Google reviews on most companies or web sites like Homestars.
