Building a house and installing a roof on the house is a multi-step process. If you are not extremely familiar with how the construction process works, all the layers that make up your roof can be a little confusing. Here is a quick break-down of how the drip edge and tar paper process of installing a roof work, and how these two steps contribute to your roof overall. The next time you talk to your contractor about what is happening with your roof, you'll have a better understanding of what they are telling you.
The Roofing Process
The first step towards creating your roof is putting up the wooden frame of your house and adding the rafters. Once the rafters are in place, they will be covered with plywood in order to create a solid foundation.
Next, before your shingles can be laid down, your contractor needs to lay down a waterproof layer. This waterproof layer will help protect the integrity of the plywood layer until you finish your roof. Once all the layers of your roof are in place, the waterproof layer will stop any water that leaks through the shingles from damaging the plywood and getting into your home.
The Waterproofing Materials
The waterproof layer is generally compromised of either tar paper or roofing felt; both materials serve the same purpose. This waterproof material is laid on top of the plywood on the main part of your roof.
Around the edges of your roof, drip edge flashing is installed to both protect the edges of the paper and to provide waterproof protection.
The Construction Process
The first thing your contractor will do is install the drip edge. They will use nails every one inch to secure the drip edge to the plywood. Whenever your contractor reaches a corner, they will overlap two different layers of drip edge in order to ensure that the corner is thoroughly covered.
Once the drip edge is in place, your contractor will lay down the tarp paper. They will start by laying down the tar paper over the drip edge; they should overlap in order to ensure maximum coverage. They will most likely use a staple gun to attach the tar paper to the plywood and the drip edge.
After your contractor applies the tar paper near the drip edge, they will work their way inward. They will overlap each layer of tar paper that they lay down to make sure that your roof is effectively protected from water. Once the tar paper is in place, your contractor will then move on to the next step in the roofing process, laying down the roofing tiles.
The next time you discuss with your contractor where they are in the process of building your home and installing your roof, you will be able to better understand what they are talking about.
