What exactly is a Roofing System? It’s more than just shingles.

Here’s a very basic explanation of your roof.
The roofing system really begins with your attic insulation. This is the layer pink, white, or yellow stuff in your attic that rests on top of your ceilings. If you look up you will see 2”x4” or 2”x6” boards every 2’ or so. These are called rafters. The rafters support your roof. If you look a little closer you will notice lots and lots of nails sticking out of flat boards. Those boards are called decking (or sheathing). The nails you see are the ones holding down your shingles. Although the next layer is hidden, it is still a very important part of the roof system. That is the underlayment. It’s also called felt paper, tar paper, or vapor barrier. The layer on top of that is the shingles – this is the layer you actually see. Shingles come in a variety of styles and colors. The last component is the ventilation. You need soffit vents to let the air in and roof vents to let the air out. Roof vents come in several styles as well. Now, you may have heard terms like valleys, ridges, flashings, etc. Think of a roof as mountain range. The peaks of the roof are called ridges and the sections where two slopes come together and the water tends to run like a river are called valleys. Flashings are made of metal and are used to cover the gaps between the shingles and walls, chimneys, and skylights. In fact there are different types of flashings too. Step flashing is a 90 degree piece of metal where the flat part is nailed to the roof decking and the vertical part rests alongside the wall, chimney, or skylight. Counter flashing is also a 90 degree piece of metal. But it is installed in exactly the opposite way. The flat part is embedded in the chimney brick and the vertical part rests on the outside of the step flashing. This ensures that no water can leak between the step flashing and the wall. Walls or chimneys with siding do not need counter flashing because the siding achieves the same effect.
