Perhaps the top two problems homeowners may face when hiring a roofing contractor are the materials and recommendations being given for your roof. Materials: If multiple materials are being used on the roofing, finding a contractor that can properly tie-in these materials is very important to ensure a water tight system. Recommendations: You'll want to make sure your roofing contractor is qualified to install the roofing system they are recommending. Also you will want to confirm that these recommendations are long term solutions not temporary fixes.

Common roofing materials for sloped roofs include shingles and metal. Common materials for flat roofs include TPO, PVC, and EPDM.
