Everything You Need to Know About Roof Restoration – Facility Executive Magazine

By John Walker

When it comes to modern commercial roofing repair, today’s contractor professionals and building owners have options. Gone are the days where the only solution to damage and leaks was a full tear-off and replacement—today, restoration methods have evolved to help commercial roofs regain their full performance potential at a fraction of the cost.

With the right high-performance products and by following established best practices, restoration can be an ideal solution for all parties involved. If you haven’t yet investigated whether restoration might be right for your next project, here’s everything you need to know:

Determining if Restoration is Right for You

Many of today’s bituminous roofs are ideal for repair and restoration. Original waterproofing bitumen are easily bonded to new modified repair mastics and coating materials. Additionally, standardized repair procedures have been perfected and can be expected to help extend a roof’s life for many years.

However, replacement is still a necessity in certain situations, depending on the overall condition of the roof. For example, many building codes and standards state any roof that is more than 20% saturated must be fully torn off and replaced.

To determine if your roof is a good candidate for restoration, you should perform an analysis on the state of the roof to determine the condition of the structural deck, insulation, and the membrane. Nondestructive and visual testing can be performed to give you a good idea of the state of the roof, and you can look for a few telltale signs of common damage:

  • Ponding water could indicate structural sagging in the deck.
  • A soft area underfoot is an indicator of saturated insulation.
  • Rusted, rotted, or cracked decking can sometimes be seen from the inside of the building and may help locate the worst areas of deck deterioration.
  • A splitting membrane may be visible to the naked eye for experienced professionals.

More thorough examination can include peel adhesion testing to determine the viability of coating solutions; core cutting, which can validate the visual moisture survey; and wind uplift testing to determine the state of the membrane. By deploying these methods, you should be able to determine if your roof is a good candidate for restoration.

Restoration Fundamentals

A good roof restoration process involves a few fundamental steps to execute properly:

  • Start by removing any debris and cleaning the roof to prepare for the rest of the project. A clean roof will be far easier to restore.
  • Next, depending on the condition of the roof, a primer is applied to ensure good adhesion for patching, stain blocking, and rust inhibition. Be sure to choose a high-quality primer to ensure the best results.
  • Patching is then performed to make sure all parts of the roof system are water-tight. Once again, high-quality products for the patching process are a requirement for a job done right.
  • Finally, protective coatings can be applied to ensure long-lasting performance. A variety of protective coatings are available, and should be selected based on …….
