How to Restore a Commercial Metal Roof

 

A metal roof can be an excellent option for your commercial building: durability, a variety of designs available and cost-effective. But that metal roof can go through wear and tear leading to problems for your facility.

With proper maintenance, your metal roof system can last a long time. And with a timely metal roof restoration, you can save a lot of money and prolong the life of your roof. In this article, we will cover the basics of commercial metal roofing, how you can restore your metal roof and the benefits of a newly restored metal roof system.

 

About Commercial Metal Roofing

Commercial Metal RoofingMetal Roofing is one of the oldest commercial roofing systems on the market. Most metal roofing systems use corrugated galvanized steel, although other materials such as aluminum or tin can also be used. After a metal roofing system is installed, a coating can be added for waterproofing, rust protection, and UV protection.

For an average commercial roof, it will usually cost between $5.00 and $10.00 per square foot in materials and labor to install a typical metal roofing system. This price range can change depending on the type and style of the metal panels you choose.

There are a few types of insulation options available:

  • Roofing Felt
  • Fiberglass
  • Rigid Board
  • Bubble Insulation
  • Spray Foam

 

Metal Roofing Problems

While metal roofing systems can have a long lifespan, this can only be obtained if the roof is adequately maintained over the years. This includes a coating to avoid rust along with proactively replacing and re-fastening damaged panels.

Here are other problems you can face with metal roofing systems:

  • Water Damage – If water ponds on the roof it can cause severe damage, such as rust.
  • Full Replacement – The substrate, or frame, is often cumbersome and difficult to work with. They require a complete tear off in almost every replacement instance.
  • Seams – The metal panels create seams that are prone to water leaks.
  • Durability – Since the metal panels are attached to the substrate, if they are not installed correctly, they can become loose when they expand and contract.
  • Noise – Weather such as rain, hail or wind can create a lot of noise against the metal material.

 

Is Your Commercial Metal Roof Eligible for Restoration?

Colonnade Tower, commercial roofing in Birmingham, AlabamaWith any commercial roof restoration, the eligibility is determined on the condition of the existing roof system. If your existing metal roof is severely damaged, then restoration may not help your problems or even be possible.

The best way to find out if your facility is eligible for a spray on roof coating, you should schedule a contractor to evaluate your existing roof system. They will be able to recommend the best solution for your facility needs.

For an existing roof system to be eligible for a roof restoration, the roof needs to be in better condition than most roofs at the end of their serviceable life. Some signs of a roof in good condition include:

  • The seams of the existing membrane are relatively intact
  • The field of the roof has been adequately maintained over its life
  • Less than 25% of the underlined substrate and insulation is wet (It is still cost-effective to do spot replacement of small saturated areas rather than a complete replacement.)

Benefits of a Metal Roof Restoration

White vs Black Commercial Roofs

A silicone restoration membrane can save your business money on time, material and labor costs. In addition to the cost-savings, there are a few other cool benefits to a metal roof restoration:

 

Cool Roof Savings

Silicone roof coatings are often referred to as “cool roofs” due to their ability to keep facilities cool. The bright white color reflects UV rays, saving buildings up to 35% in energy costs from not needing as much air conditioning to keep the facilities cool. Utilizing a bright white coating application reduces energy costs as part of the energy star cool roof solution.

 

New Warranty

A silicone restoration membrane, when installed correctly by a reputable contractor, comes with a warranty that can cover up to 15 years.

 

Renewed Protection

The silicone restoration membrane will add a new waterproof layer to your metal roof system. When properly maintained, this layer will prevent leaks into your building and protect your metal system from UV rays.
