DIY Guide to Refelting a Flat Roof: Step-by-Step Instructions

Step 1: Assess Your Existing Roof Condition

Before you begin any work, it's crucial to evaluate the condition of your flat roof thoroughly:

Look for cracks or tears in the existing felt. Check for water pooling areas. Inspect flashings and other penetrations. Step 2: Prepare Your Work Area

Remove leaves, branches, or dirt. Make sure there’s no standing water.
