What goes on a roof before the shingles?

Bottom layer This is the first waterproofing layer that is placed between the coating and the shingles. The subfloor protects the roof from harmful elements such as snow, ice and rain. Also known as a membrane, the subfloor is mandatory to provide the roof with an impervious barrier. For residential applications, felt, tar paper, or another form of subfloor are required.

Some homes have an extra layer of protection against ice and water. Typically, a cover starts with the subfloor, a combination of an ice layer with 26% water protection at the bottom of 3 or 6 feet, and then a felt-like product above. I like to say that it is the base on which the rest of the materials and components of the roof are going to be installed. If you're not sure what type of roof suits your needs, answer this roof type quiz to find the roofing material that's right for you.

Roof underlayment is a felt material (15 pounds, 30 pounds or synthetic) that is placed between the roof covering and the shingles. So we'll start at the bottom of the platform and go up through all the layers of the roof until we reach the tiles and the sunlight on the roof. Initial shingles are a pre-cut row of roofing material that is placed underneath the first row of shingles before they are installed. In order for the roof to prevent water from entering below the surface, each layer must be properly placed and installed.

Coating: This is also known as roofing and provides the basis for applying the following roof layers. When this happens, it will be much harder to pass a home inspection because your roof doesn't meet the rules. This is why it is essential to use the manufacturer's accessory for covering ridges when purchasing a dimensional or luxury asphalt roof. Once the shingles are installed on all facets of the roof, it will be time to install the ridge cover.

It ensures that there is material for the roof between the joints, where the shingles collide with each other at the edges of the roof. The five main types of roofing materials are asphalt shingles, cedar shingles, concrete or ceramic shingles, metal sheets, and rubber used in flat roofs.
