DIY Guide to Refelting a Flat Roof: Is It a Viable Option?

Introduction

Flat roofs are a popular choice for many commercial and residential spaces due to their sleek appearance and effective space utilization. However, they require regular maintenance and occasional repairs, particularly when it comes to the roof's waterproofing layer. One of the most common solutions for maintaining flat roofs is refelting. This article will serve as a comprehensive DIY Guide to Refelting a Flat Roof: Is It a Viable Option? We will explore the various aspects of refelting, including its benefits, steps involved, tools required, and much more.

Understanding Flat Roofs

What Are Flat Roofs?

Flat roofs are essentially horizontal or nearly horizontal structures that have minimal pitch. They differ from sloped roofs and are commonly found in commercial buildings but can also be seen in residential homes.

Types of Flat Roof Systems

  • Built-Up Roofing (BUR): This involves multiple layers of roofing felt that are alternated with asphalt.
  • Modified Bitumen: A single-ply roofing membrane that offers excellent waterproofing.
  • EPDM (Ethylene Propylene Diene Monomer): A synthetic rubber roofing membrane that's very durable.
  • TPO (Thermoplastic Olefin): A single-ply membrane known for its reflective properties.

    • Why Choose Refelting?

    The Benefits of Refelting a Flat Roof

    Refelting your flat roof can come with several advantages:

    • Cost-Effective: Compared to complete roof replacement, refelting is often less expensive.
    • Quick Process: Refelting can usually be done in one session, minimizing downtime for businesses.
    • Improved Aesthetics: A fresh felt layer can improve the overall appearance of your roof.

    When Should You Consider Refelting?

    If you notice leaks or water ponding on your flat roof, it may be time to consider refelting. Additionally, if your existing felt shows signs of wear but not extensive damage, refelting might be a viable option.

    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

    Clear any debris from the roof surface:

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

    Step 3: Repair Any Damaged Areas

    Before adding new felt:

  • Patch small holes with roofing cement.
  • Replace any severely damaged sections.

    • Step 4: Apply Primer

    Applying primer helps ensure good adhesion for the new felt layer:

    • Use your roller or brush to apply an even coat over the entire area.

    Step 5: Install New Roofing Felt

  • Roll out the new felt across your flat roof.
  • Ensure each piece overlaps by at least six inches for proper sealing.

    • Step 6: Seal Edges and Seams

    Once all pieces are laid down:

  • Apply adhesive along all edges and seams.
  • Use sealant where necessary to prevent leaks.

    • Common Issues During Refelting

    What To Do If You Encounter Problems?

    Leaks After Installation

    If you notice leaks after refelting, it might indicate improper sealing or installation errors.

    Blisters on the Surface

    These could form if air gets trapped under the new felt layer; ensure proper installation techniques were followed during application.
