Your Roofing System Should Be A Package Deal
There are many different shingle manufacturer's out there. There are also many different manufacturers of the accessories that go into a roofing system. Most homeowners research will research the shingle manufacturer but fail to ask the roofing contractor about the accessories that they use. From ridge vent to ice and water shield, the accessories are just as important as the shingles you select.
Most contractors can get better pricing on off brand ridge vents, ice and water shield, underlayment's, and starter/cap shingles. They will choose the off brand to save a buck. However, is it better to use many different manufacturer's and piece a system together? I do not think so and neither should you. When we visit with the homeowner and provide an estimate for replacement, we suggest a system to be installed. The more accessories used from the same manufacturer the better. We believe that the Owens Corning Duration shingle is one of the best laminated shingles on the market. We feel the same way about their accessories. The Owens Corning High Point ridge vent provides the most net free vent area per foot than any other ridge vent. The starter shingle used at the edge of a roof has high quality sealant that provides a great bond to the shingle.
The roofing system is designed by manufacturer to work together. Yes, it does cost a little more, However, peace of mind knowing that most , if not all, the accessories are from the same manufacturer will be beneficial in the long run. Plus, if there happens to be a product failure, one manufacturer isn't blaming it on another with you caught in the middle.
