Start with the house, not a brand of shingle
Tell a contractor what you have seen — a leak after a thaw, stained soffits, granules in the gutters, lifted tabs after wind, or a roof that is simply old — and ask them to walk the roof or inspect from the ground and attic when it is safe. A useful visit looks at ventilation, flashing, valleys, chimneys, and the eaves, not only the shingle color. We will not invent a life expectancy or an energy-savings percentage.
