New Roof Installations
Knowing the roofing installation process and steps you need to follow will help ensure your roof is installed properly, whether you’ve hired a professional or plan to do it yourself. This article provides an overview of the steps involved in metal roof installation and asphalt roof shingle installation. To get the lowest price for your roof repair or installation, it’s always smart to get at least four roofing price quotes from prescreened, licensed contractors. Then, calculate your roofing installation cost using our roof replacement cost calculator below and talk to contractors in your area.
Understanding the process of roof installation will enable you to make an informed decision. What to expect from your roofing contractor when he installs or replaces your roof is outlined below.
Removing the Old Roofing:
Before installing the new roofing material, the old roof will likely need to be removed. Adding too many layers (i.e., asphalt shingles) to a roof can lead to premature failure. This is why many people install multiple layers of roofing over one another. Instead, the old roof should be rebuilt using new sheathing and stopping down to the old roof.
Evaluation of the Roof:
Evaluate the sheathing in the vicinity of the old roof after it is removed. Roofing sheathing is made up of flat panels that serve as structural support and a base for installing roofing materials, such as shingles. You will need to replace any areas that are moist or experiencing trouble.
Protect Against Ice:
It’s crucial to install an ice and water barrier around your roof if you live in an area that experiences ice for even part of the year. Roof edges are treated with this product, but the bottom edges are most susceptible to ice buildup. For additional strength and stability, roofing nails are used to nail down this sticky underlayment.
Set the drip edge:
During the roof installation, drip edges are installed in two different places. As far as the lower part of the roof is concerned, the membrane should be installed before the underlayment and as far as the sides of the roof after the membrane. In the first place, install a metal drip edge over the ice and water barrier on the bottom edge of your home. Make sure the edge is flat against the roof. Then, the same method you used at the bottom of the roof needs to be applied on the sides after the roof underlayment is installed. The siding prevents rainwater from running over its edges and re-entering beneath them.
Installing roofing underlayment:
It is available in two thicknesses, 15# and 30#, which provides water resistance. Felt paper underlayment is twice as durable as 15#, even compared to synthetic products. In addition to protecting the roof itself, synthetic underlays are the most convenient and durable. Use roofing nails every eight inches in the middle and every four inches along the edge of the underlayment to secure it into place. Rather than going through the drip edge, these nails should sit just above it. While rolling out the roofing underlayment, ensure that the lower row overlaps the next row by at least six inches. Next, secure the roofing caps to each row. The underlayment should be laid to the peak, then the roof straddling the peak should be trimmed off so that both sides are covered in the same way.
