Metal roofs, known for their longevity and resilience, occasionally require a fresh coat of paint to maintain their aesthetic appeal and protective qualities. This article, brought to you by Benson Contracting in Glens Falls, NY, provides a detailed, step-by-step guide to painting your metal roof, ensuring durability and an enhanced appearance.

Step 1: Roof Inspection

Before embarking on your painting project, thoroughly inspect your metal roof. Look for signs of rust, damage, or loose seams. Addressing these issues prior to painting is crucial for a lasting finish. Also, examine the soffit and fascia for any signs of wear.
