How to Install a New Roof 

As you frame your roof, remember that flat roofs aren’t actually flat. They have a slight incline to prevent rain and snow from collecting and causing leaks which lead to dangerous mold. Once you frame your roof and allow for a sight pitch, you’ll want to lay your sheathing. 

Sheathing is typically done with plywood. This step is done to allow for equal weight distribution across your roof and will help as rain and snow accumulate. 

Another benefit of sheathing is its ability to distribute the weight of your shingles. Make sure to use plywood that’s 5/8″ thick when sheathing your roof. 

Install an Underlayment

An underlayment for your roof is installed before your shingles. It’s water-resistant and forms a protective layer from the elements. It’s also known as roof felt or tar paper, and is an essential step. 

Traditionally, 30 pound felt is used and applied on top of your sheathing. As per local codes, you can apply it with staples or roofing nails. 

Flashing

Flashing is a crucial step that should never be skipped. It helps protect your roof from the elements, as well as debris. The trick is to locate areas where water might accumulate, and apply flashing in those spots. 

Apply it around the edge of your roof and along chimneys to keep water and moisture out. 

Finishing Touches

Since shingles aren’t recommended for flat roofs, it’s best to apply a rubber or tar material to flat roofs. Shingles may allow water to seep into your home, so avoid them if possible. 

Whether you tar or rubber a flat roof, be sure to have the appropriate materials. Some rubber roofs come in rolls of EPDM roofing that you glue on, while other materials you apply like you would tar a driveway. While tar is a common material, rubber comes highly recommend since it can hold up against extreme weather. 

Flat roofing is different from traditional sloped roofing, so be sure to follow these steps for a water-resistant roof. 

You may be wondering, “How long does a new roof take to install?” Flat roofs can take around 3 days since the materials need time to dry, so be sure to plan accordingly.
