What type of roof should you not walk on?

The roof of your home is a vital protective barrier, shielding you from the elements. While it may seem tempting to use your roof as a vantage point or a place for repairs, not all roofs are designed to withstand foot traffic. In this article, we’ll explore the types of roofs you should avoid walking on, understanding the reasons behind this caution and how to safely navigate maintenance tasks.

  1. Asphalt Shingles:

Asphalt shingles are common due to their affordability and ease of installation. However, they are not designed to support the weight of a person walking on them. The granules on the shingles can easily dislodge, causing premature wear and reducing their effectiveness in protecting your home.

  1. Clay and Concrete Tiles:

While these tiles are durable and aesthetically pleasing, they can be brittle and prone to cracking if walked on. The weight concentrated on a small area may lead to structural damage, potentially requiring costly repairs.

  1. Slate Roofing:

Slate roofs offer a timeless and elegant appearance, but they are also among the most delicate roofing materials. Walking on slate can cause tiles to break or crack, compromising the roof’s integrity and leading to leaks.

  1. Metal Roofs:

Metal roofs are durable and long-lasting, but they are not immune to damage caused by foot traffic. Walking on a metal roof can dent or scratch the surface, affecting both its appearance and performance.

  1. Flat or Low-Slope Roofs:

Roofs with a minimal slope or those designed to be completely flat are particularly vulnerable to damage from walking. The lack of pitch can lead to water pooling, which, combined with the added weight of a person, may result in leaks or structural issues.

Why You Should Avoid Walking on Certain Roofs:

  • Protective Coatings: Many roofing materials have protective coatings that can be easily damaged by foot traffic, compromising their ability to repel water and resist UV rays.
  • Structural Integrity: Some roofs, especially those with delicate materials, may not be able to support the concentrated weight of a person, leading to cracks, leaks, or even collapse.
  • Warranty Considerations: Walking on a roof that is not designed for foot traffic may void the manufacturer’s warranty, leaving you responsible for any future repairs.

How to Safely Navigate Roof Maintenance:

  • Use a Professional: When roof maintenance or repairs are necessary, it’s advisable to hire a professional roofing contractor with the expertise and equipment to work safely.
  • Use Walkways or Boards: If you must access the roof, consider using walkways or boards designed to distribute weight evenly, reducing the risk of damage to the roofing material.
  • Inspect Regularly: Regular visual inspections from the ground or using binoculars can help you identify potential issues without the need to walk on the roof.


Knowing which roofs to avoid walking on is crucial to preserving their integrity and maximizing their lifespan. If roof maintenance is necessary, always prioritize safety and consider consulting with a professional roofing contractor to ensure the longevity of your home’s protective covering.
