8 Steps for Conducting a Thorough Roof Maintenance Inspection

Posted by Nicole Gale on Thu, Sep 18, 2014 @ 02:00 PM

roof_maintenanceIn order to maintain a properly functioning roof coating system, preventative roof maintenance is necessary at least twice a year. It is recommended to complete this roof maintenance checklist before the rainy season begins, aka NOW. This ensures you have ample time to correct any issues that could cause leaks and damage to your building.

  1. Remove any debris on the rooftop. The roof has many locations that are ideal for gathering debris such as pipes, skylights, pitch pans, HVAC units, etc… It is important to remove any debris such as leaves, trash, branches, rocks, etc… because they trap and hold water, promoting ponded water and early roof deterioration.

  2. Unclog all drains. Make sure all drainage systems are open and functioning appropriately. It is a good idea to test them by pouring water down each one as a clogged drain causes deterioration, ponded water, and possible leaks.

  3. Check your gutters. Clear them of debris and anything that would prohibit them from functioning properly.  

  4. Inspect the roof surface for blisters and/or delamination. If you see these, we suggest you call National Coatings for a professional roof inspection. Contact us for advice from a roof coating profession - no obligation to buy!

  5. Check the entire roof surface for any deterioration, holes, mechanical abuse areas, defects, and/or separation - pay attention to stains and discoloration of the roof edges and surrounding walls as they are possible indications of a leak - if you experience any of these failures, contact us and consider an AcryShield Roof Maintenance (ARM) System, so you don't have to replace and tear-off your roof later - this will save you thousands of dollars.

  6. Carefully inspect all joints. Make sure joints at wall and equipment base flashings and near pipe penetrations are undamaged, watertight and intact.

  7. Make sure sealants and caulking are effectively working. If you are looking for a premium quality sealer, learn more about AcryFlex. It is an elastomeric acrylic sealant that provides a water-based, sealant that is engineered for long-term flexibility, adhesion and weather resistance.

  8. Maintain your Landscaping - Trim back and remove any trees near your roof to avoid excess debris and/or penetrations to your roof surface.

Preventative roof maintenance prolongs the life of your roof, ensures a greater return on investment for your roof coating system and lowers roof maintenance costs in the future. Just a small amount of time maintaining your roof every six months will prevent the need to perform costly repairs. If you ignore your roof, small, inexpensive concerns become large, costly issues. We advise you check your roof semi-annually - the beginning of Fall and the beginning of Spring are generally ideal times as weather conditions are usually milder. It is also important to inspect your roof immediately after any large storms, high winds, hail or other damage causing conditions occur.

What’s the Big Deal about a White Roof?

Posted by Nicole Gale on Thu, Aug 28, 2014 @ 12:18 PM

Wondering why a white roof is so popular? Is there a difference between a white roof and a cool roof? Can white roofs really save me money?

specialty_coating_picWhite roofs are becoming more and more popular as people are intentionally trying to be more economically and environmentally conscious. They offer the following benefits:

  • Lowered energy usage and costs
  • Renewable and Sustainable
  • Cost savings
  • Improved employee comfort
  • Business open during installation
  • NO costly and timely roof tear-off
  • NO landfill fee’s

A white roof is generally described as a roof with a white surface. They are also associated with a ‘cool roof’ because they reflect heat away from the roof, keeping the interior of the building cooler. White roofs absorb only a fraction of what a dark surfaced roof would absorb, drastically cutting down on your air conditioning usage and costs. (Check out how Harbor Freight benefited from energy savings using an AcryPly Roof Restoration System.) It is important to note, that cool roofs do not necessarily need to be white in color. A cool roof is any roof with a reflective surface, the most reflective roof surface is in fact a white roof, but you can have a reflective grey, sand, teal, etc… colored roof that also provides reflectivity. For more information on cool roofs, download the Cool Roof Buyer’s Guide

A white roof coating system provides an excellent solution to cost savings when you are faced with roof leaks and failures. These systems are applied directly over your existing roof, allowing you to extend your roof life and save 50-70% of the total cost it would take to do a traditional roof replacement. The labor for a roof coating system versus a roof replacement is much less and you are able to conduct business as usual, with no noise or odor disruptions and no closures during construction.

Contact a Roofing  Professional  Zero ObligationNot only do white roof coating systems cool your building with its ability to reflect the sun’s heat but it also allows you to extend the lifespan of your roof while lowering your maintenance fee’s. The sun’s heat is the leading cause of damage and deterioration to a roofs surface. By reflecting the UV rays away, the coating is protecting and acting as a barrier against the heat - increasing the service life of your roof. White roof coating systems are renewable, allowing you to restore your roof indefinitely. Contact National Coatings to find out how you can sustain your existing roof without ever needing to do a costly roof tear-off again.

Downside to Aluminum Roof Paint (aka Coating)

Posted by Nicole Gale on Tue, Jul 01, 2014 @ 12:00 PM

Aluminum Roof Paint When considering a roofing system for your commercial roof, longevity, waterproofing, sustainability and durability are all necessary and important factors to research. While aluminum roof paint can provide durability and waterproofing, it poses some issues with sustainability and longevity. 

What is Aluminum Roof Paint

Aluminum roof coatings are solvent based formulated with asphalt, aluminum paste, moisture scavenger, fillers and hydrocarbon solvents. High quality aluminum roof paint options will contain high amounts of aluminum pigment to increase the reflectivity values.  ASTM D2824 –Standard Specification for Aluminum Pigmented Asphalt Roof Coatings provides resources and assistance in selecting an aluminum roof coating that is suitable for roofing applications.

Downside to Aluminum Roof Paint

FREE GUIDE:  Restore Your Aging  Roof with SiliconeThe greatest issue we have with aluminum roof coatings is its inability to adhere to other waterborne and acrylic roof coating systems in the future. This hinders its ability to be easily sustainable and renewable.  The aluminum flakes in the coating interfere with adhesion, making delamination a potential issue, increasing roof failures from occurring. Solvent-based primers can be used to support adhesion to the aluminum flakes; however, the bond between the coating and primer can still cause issues and many roof coating manufacturers shy away from the idea. We recommend contacting the roof coating manufacturer before construction begins.

Unlike acrylic coatings, aluminum coatings do not provide any waterproofing properties. They do increase reflectivity and UV protection to the roof substrate but do not improve appreciable mil thickness to the roof.  Acrylic roof coatings form a seamless, monolithic membrane when applied, creating a watertight, durable roofing substrate. Lastly, due to aluminum coatings being solvent based, they are typically higher in Volatile Organic Content VOC’s, causing unpleasant and potentially harmful odors during application. (Click here for more information on low VOC Roof Products).  

Roof coatings or roof paints are continually increasing in popularity because of their ability to be restored and renewed the current roof. They provide lower life-cycle costs, fewer disruptions to your business, lower roof maintenance costs and less hassle compared to traditional roof replacement. The sustainability factor for these roof-coating systems offer great over-all value and provides you with excellent longevity to your roof substrate.  

National Coatings offers sustainable roof restoration and roof maintenance systems that provide ultra-high reflectivity, durability, waterproofing, as well as, sustainability. All of our elastomeric roof coatings systems can be renewed, allowing you to extend your roof’s service life indefinitely.
