There are multiple different materials that are used in roof repair and roof replacement. These materials include roof decking, roof flashing, underlayment, drip edge, ice and water shield, asphalt shingles, ridge capping, roof vents, and pipe boots. Roof decking is made of the wooden boards that make up the framing of your roof. Roof flashing is metal that is placed where your shingles press up against something such as a wall or chimneys. Underlayment is a felt material that is placed over your roof decking and provides extra protection. Drip edge is the type of metal flashing that gets installed at the edges of your roof to help control the flow of water away from your roofing components. Ice and water shield is a waterproof material that is placed to protect your roof from ice and water damage. Asphalt shingles are the top part of your roof that we see when we look at the roof. Ridge capping is trim that is installed where two slopes of a roof meet. Roof vents are vents that allow your attic to breathe properly by providing proper ventilation. Pipe boots are made of synthetic rubber and they are placed around your roof pipes to prevent leaks.
