One critical part of your roofing contract is the “Scope of Work” section. This part should break down every step of the process, giving you a clear overview of what will happen from start to finish. Before you sign anything, make sure your contract includes these 10 essential steps to avoid any surprises and ensure a high-quality roofing job.

1. Material Delivery

Before the work begins, expect all the necessary materials to be delivered to your property. The ideal scenario is having these materials placed directly on your roof, but if obstacles like low power lines or a weak driveway exist, arrangements should be made to store them in a convenient spot of your choosing.

2. Removal

A good roofing team will take measures to protect your property, including patios, decks, and landscaping, before removing the old roof. This step is crucial to prepare for the new installation, followed by an inspection and replacement of the wood decking if needed.

3. Dry-In Protection & Drip Edge Installation

The underlayment (usually roofing felt or a synthetic alternative) is rolled out to provide a secondary barrier against water. Then, drip edge is installed along the edge of the roof.

Next, flashing and ice & water shield are installed around roof penetrations such as chimneys, vent stacks, or skylights to direct water away from these areas and prevent leaks.

The installation of an aluminum drip edge along all edges of the roof is next. This is a code requirement and a critical component in protecting your home from water damage.Depending on the city or county, a dry-in inspection will take place. Inspector from the city or county will visit the job site to make sure the decking is re-nailed per code.

Once it is approved, the roofers may continue with the next step — Installing the shingles.

4. Start Strips
