The roofing materials you put on your roof are integral to the durability of your home. They are placed on top of one another to form the roof, providing protection and support. The layers vary depending on your roof type, with some roofs having up to five or more layers. The roof is designed to resist high wind speeds, cold and heat. The primary purpose of each layer is to provide this protection. Here we will discuss roofing layers, the aim of each layer, and how they support one another.
1. Roof Deck
The roof deck is the initial layer of material on your roof. It provides support for each of the following layers that are put on top of it. It is made of heavy-duty plywood, multiple layers of asphalt-saturated timber panels, or other materials. The deck should be strong enough to endure harsh weather conditions, keeping your house secure and intact while offering support to the higher levels. It must withstand the weight of snow and heavy rain, hail, strong winds and high temperatures.
The underlayment provides a solid foundation for your roofing materials. It is designed to be installed on the roof deck. It gives a material bearing point for wood or plastic shingles. The underlayment is made of a material that is tough, water-resistant and flexible. A solid felt layer or many sheets of tar paper are used to provide this resistance. Staples or nails can mechanically fasten the underlayment to ensure it is put in place properly.
3. Ice and Water Shield
This layer provides a leak-free barrier between the roof deck and the top layer of your roof. The water shield stops leaks caused by melting ice going down through the cracks of your deck into your home. It protects any insulation installed in the attic. The material must also be waterproof and tough.
4. Ridge Vents
Ridge Vents are designed to provide your roof with ventilation. They set up a one-way airflow that helps cool your attic, preventing you from having to use your air conditioning in the summer. The vents also help prevent ice damage in the winter. They are fitted into your roof deck, letting air in but not allowing water out. They are placed at the highest spot on the edge of your roof, at each corner along all sides of your home, and at the center’s highest point.
Shingles are designed to warm your home by reflecting incoming heat into your attic. They are made of a very thin layer of asbestos, asphalt, compressed fiberglass, or plastic shingles. Plastic shingles are the least expensive but make you more vulnerable to leaks. They can be put on almost any kind of roof. Asphalt shingles are sturdier and must be placed on a wood deck. They help prevent hail and wind damage to your home.
