1. There is a difference between price and value. Understand that no matter what you need, there always will be a contractor who will do it for less. A cheaper price doesn’t equate to better value. Roof systems and roof repairs can’t be purchased like a commodity where shopping around can pay off. Get multiple bids, but base your decision on more than price. Look for a knowledgeable and experienced contractor with good references who will provide a competitive price and superior service. If you only look at price, you risk getting a bad product and inferior service.

2. Recognize the importance of routine maintenance. If you are proactive, your roof’s life can be extended and you ensure resources are well-spent—you also avoid having unhappy tenants. Roofing contractors often have to replace roofs that could have had longer lives with scheduled maintenance. Before you need a new roof or leak repairs, a little regular maintenance can go a long way. Find a contractor who will service your roof and make necessary repairs.

3. Alternatively, homeowners and building owners also need to understand when roofs are beyond repair. Sometimes, a roof cannot be saved. Sometimes, repairs won’t provide lasting or appreciable value. The situation can be frustrating when a lot of roof repairs are made and leaks persist. Don’t turn your roof into a money pit; work with your roofing contractor to predict when you will need a roof system replacement so you can budget appropriately.

4. Find a roofing contractor who is established and reputable. Ensure your contractor has proper licensing, carries appropriate and valid insurance, and performs most of the work. A contractor who only uses subcontractors may not have appropriate insurance or licensing. This is a risk for owners, so don’t be afraid to ask for proof of insurance and licensing.
