Welcome to Bio-One Atlanta's FAQ page, where we address common questions and concerns about maintaining and improving your roof. Today, we'll answer an important question: Is it possible to coat an old roof instead of replacing it? We understand that roof replacement can be a significant investment, so exploring alternative options like roof coating is a prudent choice. Let's delve into this topic and provide you with the information you need to make an informed decision.

The Benefits of Roof Coating

Before we delve into whether it's possible to coat an old roof, let's discuss the benefits of roof coating. Roof coating is a protective layer applied to the roof surface that helps extend its lifespan and improve its performance. Here are some key advantages:

  • Enhanced Durability: Roof coatings provide an additional layer of protection, shielding your roof from UV rays, weather damage, and other harmful elements.
  • Cost Savings: Coating your old roof can be a cost-effective alternative to complete replacement. It helps minimize maintenance and repair costs, and it's comparatively affordable compared to a full roof installation.
  • Energy Efficiency: Certain roof coatings have reflective properties, reducing heat absorption and helping to maintain a cooler interior, resulting in potential energy savings.
  • Environmental Benefits: By choosing roof coating, you contribute to reducing waste by extending the life of your existing roof, resulting in less material ending up in landfills.

Can You Coat an Old Roof?

Now, let's address the main question at hand. Yes, it is possible to coat an old roof instead of replacing it under certain conditions. However, there are important factors to consider:

Roof Condition

The condition of your old roof is a crucial factor in determining whether it is coatable. Roof coatings work best on roofs that are still structurally sound and with minimal damage. If the roof is severely deteriorated, has extensive leaks, or underlying structural issues, roof replacement might be a more appropriate solution.

Inspection and Evaluation

Before opting for roof coating, it is essential to have a professional inspection performed by an experienced roofing contractor. They will assess the current state of your roof and provide recommendations based on its condition.


Not all roof types are suitable for coating. It's important to determine if your particular roof material is compatible with the coating products available. Popular roof types that can usually be coated include metal roofs, asphalt shingles, concrete, and some single-ply membranes.

Preparation and Cleaning

Prior to applying the roof coating, proper preparation is essential. This involves thorough cleaning, removing debris, and repairing any existing damage. Professional roof cleaning services can ensure optimal surface preparation for coating application.

Professional Application

For best results, it's recommended to hire a professional roofing contractor who specializes in roof coating. They have the expertise and equipment to apply the coating correctly and ensure proper adhesion to your old roof.


Coating an old roof can be a viable solution if the roof's condition permits and it is compatible with the roof material. However, it's crucial to have a professional inspection and evaluation to determine the feasibility and to ensure proper preparation and application.
