Why not brush up on basic areas of house construction and home improvement, such as roofing? You don’t have to learn enough for a certification or DIY work. However, you can at least familiarize yourself with terms and components so you can more ably discuss a project with your roofer in Palo Alto should the time for repairs or replacements come around.
The roof itself, which you see from outside a house, has several layers. At the outermost are the shingles or tiles that give a roof color, texture, and its first protective barrier against the elements. These are placed above underlayment and decking, which further seal a house from rain, snow, wind, and heat. Drip edges are installed at the sides of a roof, usually over underlayments, for added protection. Waterproof metal sheets, called flashing, are also placed on the roof to keep water from pooling in its nooks and crannies.
