Types of Metal Roof: Standing Seam Sheet Metal Roofing, Batten Seam Sheet Metal Roofing, Flat Seam Sheet Metal Roofing and Tinplate Roofing.

I. GENERAL

1.01 SUMMARY

Our metal roof coating systems offer a complete solution with a substantially lower investment than replacing your entire metal roof. In addition the metal roof coating system creates a highly reflective seamless membrane which will greatly reduce the metal roof surface temperature and energy cost.

  • This outlines Metal Roof repair, coating and restoration procedures for the application of Fixallroof Coatings to fix roof leaks and extend the service life.
  • These are suggested specifications and actual application requirements may vary and are the responsibility of the installer.
  • The manufacturer’s application instructions for each product used are considered part of these specifications and should be followed at all times.

  • Comply with the instructions and recommendations of the roof restoration system manufacturer.
  • Comply with manufacturer’s product data, including product technical bulletins.

3.02 EXAMINATION

  • Verify conditions are acceptable for application of roof restoration system.
  • Inspect metal roof to receive roof coating and make sure they are clean, sound, properly prepared and free of moisture, dirt, debris or other contaminants.
  • Verify that all on-roof items, penetrations, mechanical equipment, hvac drains are in place and secure. All airconditioning and air intake vents should be suitably protected or closed.
  • Verify that areas within the vicinity of the application area as protected from overspray.
  • Verify that all roof drains, gutters, downspouts, catch basins are clean and in working order.

3.03 PREPARATION

  • Cleaning: The entire metal roof surface must be clean, sound, dry and free of any contaminants that would interfere with the proper adhesion of the roof coating. This may require pressure washing, scraping, wire brushing or other means necessary while observing responsible trade practices. All loose paint and rust should be removed before applying any product.
  • Residual Asphalt: Installer shall make every effort to remove all loosely adhered asphaltic roofing elements.
  • Ponding Water: Contractor shall make every effort to mechanically eliminate all ponding water areas on the metal roof prior to application of any roof coating product. For roofs with minor ponding (ie. small puddles less than 1/2″ deep) that cannot be corrected, consider using the solvent system.
  • Repairs: Repair and dented and/or damaged roof panels to correct any ponding areas.
  • Do not apply coatings until all unsatisfactory conditions have been corrected in a manner acceptable to the original metal roofing manufacturer.

3.04 APPLICATION

  • Inspect metal roof to receive roof coating. Always perform a coating adhesion test before doing the entire job.
  • Primer: Entire metal roof shall be primed using the appropriate primer and following the application rates specified in the table below.
  • Seams: All seams, penetrations and parapet walls should be flashed using PolyScrim Fabric and PrimeLock Bonding Primer. Apply a thin coat of PrimeLock Bonding Primer over the seam and roll out 6″ fabric over the seam and apply another coat of PrimeLock Bonding Primer over the fabric. Encapsulate the fabric with the appropriate elastomeric coating and feathering it at least 2″ to 3″ past the edge of the fabric. Substitute PrimeLock Bonding Primer with Butyl Rubber Coating when installing a solvent system. Read 2.02 for details.
  • Exposed Fasteners: Exposed fasteners should be inspected, tightened or replaced as needed. Fastener heads should be caulked.
  • Base Coat: Apply appropriate base coat using the application rates specified in the table below. Allow to dry thoroughly for 24 hours depending on humidity and temperature.
  • Top Coat: Apply appropriate top coat in a cross-hatch technique using the application rates specified in the table below. Allow to dry and cure before exposing to foot traffic.
  • Standard System: Use the Acrylic System for metal roofs with good slope and no ponding water issues. Use the Solvent System when outdoor temperatures are no longer favorable for acrylic coatings.

3.05 FIELD QUALITY CONTROL

  • Utilize manufacturer’s field services to verify proper installation of the system. Areas that do not meet the minimum standards for application specified herein shall be corrected at the contractor’s expense. Manufacturer’s inspection or verification shall not constitute acceptance of responsibility for any improper application of material.

3.06 CLEANING

  • Surfaces not to be coated shall be protected during the application of the system. If protection is not feasible, surfaces shall be restored to their proper condition by cleaning, repairing or replacing.
  • In conjunction with the final inspection, all debris, containers, materials and equipment are to be properly removed from the job site. Grounds are to be cleaned undamaged and acceptable to the owner.
  • Dispose of all containers in accordance with state and local environmental regulations.
  • Reflectivity of coatings may be reduced if roof surface is not cleaned regularly. 3.07

PROTECTION

  • Control overspray especially during windy conditions.
  • All parking areas adjacent to (within 75 feet ) the work area are to be cleared and roped off.
  • Protect work from damage due to subsequent construction activity on the site.
  • Roof coatings are not traffic grade. Areas surrounding roof top equipment may be reinforced by embedding PolyScrim fabric and applying a thicker membrane (40 – 50 mils). Walk pads should be used if frequent maintenance traffic is expected.

      I ordered a gallon of Liquid Rubber last summer, and inquired if it could be spread with an adhesive applicator trowel; the sales person was not aware of this having been tried. I tried using a commercially available trowel with 4 sawtooth teeth per inch, and 0.135 inch notch depths, holding the trowel at about a 45 degree tilt.

      Everyone was SUPER helpful and knew the product, properties and application methods well. I applied to product on the trailer in about a 2-hour period one evening. It was tricky with the application, from a novice who had not done this before.

      We have completed the resurfacing of our commercial roof back in April and ordered a few more pails for areas where we probably did not apply it thick enough. Just wanted to share these photos with you.

      You have a great product here and we will be ordering for future jobs we have. We were a bit skeptical at first but when it was fully dry it looked as if we installed a new 15,000 sq piece of sheet EPDM.

      This will be the third time our firm has ordered. We completed a project in 05 in the fall and waited for the winter. This was actually the first winter without any leaks. Great product overall.
