Your roof is more than just shingles. It is a complete system that also requires hip & ridge shingles, ventilation and waterproofing underlayment products. Each of theses elements plays an important role in protecting your Maryland home, and they work together to ensure the beauty and durability of your roof.
There are many ways roofs get installed. There is only one right way. That's the way specified by the people who manufacture roofing system products. Directions are printed on every bundle of roofing shingles sold. Every single one. You might go to a local supply house and take a look. Jot down some notes. See if the Maryland roofing contractor you are interviewing has a good grip on what manufacturers have to say. If your roof isn't installed to the manufacturer's specifications, your roofing material warranty may be toast.
