Flat Roof Repair (Inspection, Materials …)

Posted By: Matt Watson

Flat roofs are a common feature in both commercial and residential buildings, particularly appreciated for their economical construction and suitability for installing equipment like solar panels and air conditioning units.

However, the unique characteristics of flat roofs demand specific maintenance and repair strategies to ensure their longevity and performance. If you’re looking to learn all about flat roof repair, we’ve got you covered. This blog post will guide you through everything you need to know about flat roofs, including:

  • Recognizing damage signs
  • Repairing them
  • Maintaining their structure to avoid future damage

What is a Flat Roof?

A flat roof, as the name implies, appears flat, but it usually has a slight slope to allow water drainage. Unlike pitched roofs which have a noticeable incline, flat roofs are almost level but typically have a slight pitch of about 10 degrees to facilitate water run-off.

Common materials used in flat roofing include:

  • Tar and gravel
  • EPDM (rubber)
  • PVC
  • TPO
  • Modified bitumen

These materials are selected for their ability to form a continuous, waterproof barrier that stands up well against the pooling of water.

Why Flat Roofs Need Different Materials

The material selection for flat roofs differs from sloped roofs due to their potential for water pooling. Flat roofs require materials that can offer a watertight seal and withstand the weight of standing water and the associated wear and tear.

Materials like EPDM rubber are favored for their elasticity and durability under fluctuating temperatures and weather conditions. These materials must also resist the effects of UV radiation and be flexible enough to handle the building’s structural movements.

Signs of Flat Roof Damage

Identifying damage early can significantly reduce the cost and complexity of repairs. Common signs of flat roof damage include:

  • Pooling Water: If water remains on the roof for more than 48 hours, it can degrade the roofing material and increase the risk of leaks.
  • Visible Cracks or Tears: Materials like rubber and bitumen can develop cracks or tears due to age or physical damage.
  • Blisters or Bubbles: These occur when air or moisture gets trapped under the roofing material, indicating adhesion problems.
  • Interior Water Stains: Stains on ceilings or upper walls often indicate roof leaks.
  • Increased Energy Bills: Unexpected increases in heating or cooling costs may be due to insulation issues related to roof damage.

How to Repair Your Flat Roof: 4 Step Solutions

Repairing a flat roof involves several steps, which can vary based on the material and extent of the damage. Common repair methods include:

1) Patching:

Small cracks or holes can be patched using a suitable sealant or a piece of roofing membrane.

2) Reapplication of Coating:

Applying a new reflective coating can extend the life of the roof and improve energy efficiency.

3) Replacing Sections:

Larger damaged areas may need sections of the roofing material to be completely replaced.

4) Ensuring Proper Drainage:

Adjusting the slope of the roof or clearing drainage paths can prevent future pooling.

DIY vs. Professional Flat Roof Repair

While some minor repairs can be DIY projects, major repairs often require professional handling. DIY repairs can be economical but risk improper installation or assessment. Professionals, while more costly, bring expertise, appropriate tools, and materials, ensuring that repairs are performed correctly and safely.

The Cost of Repairing a Flat Roof

The cost of flat roof repairs can vary widely depending on the extent of damage and the materials used. Minor repairs might cost a few hundred dollars, while extensive repairs or full replacements can run into thousands. Regular maintenance can help mitigate these costs by extending the roof’s lifespan and preventing severe damage.

Maintenance Tips to Avoid Future Damage

Regular maintenance is crucial in extending the life of a flat roof. Key maintenance tips include:

  • Regular Inspections: Conduct bi-annual inspections and after major weather events.
  • Keep the Roof Clean: Remove debris, leaves, and standing water.
  • Check and Repair Seals and Flashings: Ensure they are intact and watertight.
  • Apply Protective Coatings: These can reduce wear from UV light and weather.

Finding a Quality Commercial Roofing Contractor

Choosing a reliable roofing contractor is vital for ensuring quality repairs. Look for contractors with:

Proper Licensing and Insurance:

This protects you against liability and ensures they meet industry standards.

Experience with Flat Roofs:

Experience in flat roofing ensures they are familiar with the specific challenges and best practices.

Good Reviews and References:

Check their reputation through reviews and ask for references from past projects.
