Refinishing of Metal/Steel Roofs on Factories, Plants & Warehouse Buildings

You have a very important investment in the contents of your factory, plant or large building. Whether you own that facility, have the responsibility for maintaining it, or both, it represents a vital element for your business and profits, as well as representing a liability if neglected. Protecting that investment is your roof, which attracts little attention until it leaks.

Roofing Failure Modes

Working tirelessly and quietly 24 hours a day, 365 days a year for many years, your industrial or commercial roof is exposed to the elements, weather, sun, airborne pollution, rain, etc. — all of which take their toll on its metal surface and normally resulting in corrosion. Regardless of whether your roof comes with a factory finish or is bare galvanized steel, the effects of corrosion will cause the roof fasteners to corrode and allow entry for water into your structure if given enough time. Corrosion will also wear through the sheet steel, causing it to become very weak, perforated, to leak, and eventually need replacement.

The results of the steel wearing out include costly damages to equipment, inventory, operations, shutdowns, safety hazards, and costly ongoing maintenance. Finding and spot-fixing a leaking roof can be a very difficult process, since water can enter at one spot, follow the top of a structural beam hidden from view, and then show up in a completely different location of the building as leaking water. Such a crisis can be avoided through a professional roof inspection that will help you in planning and budgeting for your long term roofing needs.

Roof Sealing & Refinishing

Induspray has been painting industrial and commercial facilities for over 40 years, including the remediation and protecting of our clients’ roofing investments. Utilizing systems that are designed to encapsulate the roof and stop damaging corrosion, we can extend the life of your roof for years to come.

Offering a no-cost inspection with detailed findings, we recommend the best-value solutions for your needs and budgetary constraints. You will always be aware of all your alternatives, and thus be empowered to make an educated decision on what system to go with. Our best client is our most knowledgeable client.

What options are available for customers with a deteriorating roof? If a roof is experiencing signs of visible corrosion but no leaks, it can be treated with a direct-to-rust epoxy primer to stop the corrosion (the epoxy catalyzes in the rust, stopping the corrosion and preventing air and water from reestablishing corrosion), and finish coated with a durable urethane for long term aesthetic performance.

If the roof is leaking, a good choice is an elastomeric roof coating system designed to encapsulate the roof, bridging all gaps and seams to act as a wrapping system for the roof. Elastomerics have great elongation and provide excellent waterproofing performance when combined with sealing the seams and entry points of the roof with the appropriate accompanying systems.

At a small fraction of the cost of replacement, these types of restoration systems are selected by owners as an effective and cost-efficient alternative to complete replacement. Low pitched roofs tend to get more sun exposure and accumulate more dirt. On buildings where snow falls, if the roof is left unclean, as ice and snow slide down the roof, this surface dirt under the ice and snow can act like sandpaper, removing the protective factory paint finish and leaving the roof with little or no film of paint for corrosion control.
