Metal Roof Recoating or Refinishing

Many roofs in the 30 plus year range have an architectural profile, meaning they use coil coated sheet steel sheer cut and stamped with a particular fluting (corrugation) profile to give the panel rigidity and strength. These panels vary in width and length depending on what the profiler has orders for. Older metal roof were all made from these panels. Installers bought these panels from a variety of profile manufacturers and would lay them on the structural supports and screw them together using caulking or gasketing on the underside of the panel to seal them from leaking. The fastener screws also had rubber washers to keep them water tight.

These architectural panels work well for vertical walls on a building but when used off vertical they are exposed to much more extreme wear due to sunlight, rain, dirt, snow and ice accumulation. The combination of dirt and ice sliding off the roof in the early spring or a warm winter day acts as sandpaper to scrape the paint off the roof while the precipitation and the sun wear out the paint and the weather seals.

The roof panels left unpainted would start to rust very quickly and sometimes leak as well.

More current metal roof systems are designed quite differently; they use standing seams elevated around four inches off the roof surface, spaced out approximately a foot and a half from each other vertically on the roof. These seams (peaks of the panel profile) are then water proof capped allowing the rain and snow to flow down the pitched roof to the gutter system at the bottom edge of the roof.

This standing seam roof design is far less likely to leak but the paint wear on the roof is still harsh.

As experts in metal roof refinishing, Induspray offers a number of different roof recoating systems. We supply labor and materials installed.  Corrosion control is the start using a variety of primer systems, topped with elastomeric coatings for water sealing and urethane systems for sun exposure. Colour choice is very wide.

Saving Money When Painting Your Plant Ceiling

The painting of ceilings and walls in an operational manufacturing plant or warehouse requires some careful planning and thought for both the client and the painting contractor.

Little logistical issues can make a big difference for both the operation of your factory while its being painted and the painting contractors ease of painting the area contracted..

Work area access in terms of the size of the area and the level of clearing of equipment the customer has done prior to the painter can make a big difference in the quotations you’ll receive. The bigger the area cleared and accessible for each phase of the project the lower your quote will be.  

If the whole plant is available to be worked in that is even better as more painting can be done at the same time and covering time is minimized. This will minimize encapsulation costs to isolate the area being painted from the rest of the plant takes time and material and maximize the efficiency of the painting contractors project manager.
