E.M. Hundley Hardware Company's building was an aging metal roof system over twenty years old that was revealing inconsistent nuisance leaks to the interior sales floor. IRC specified a National Coatings AcryShield® maintenance coating system consisting of two-coat, 100% acrylic and elastomeric custom color coating system with localized polyester fabric reinforcement at all metal panel end joints.

"National Coatings makes this approach feasible not only with excellent coating products but also with the wide range of accessory products from rust-inhibitive primers to individual butyl caps to encapsulate the existing panel fasteners." - Project Manager, Mr. Rob Worthing

Semi-Annual Roof Maintenance Checklist

Posted by Nicole Gale on Tue, Oct 13, 2015 @ 11:00 AM

Roof maintenance is an essential step to protecting your assets. It's necessary to develop a good habit of preventative roof maintenance every six months starting the year your AcryShield roof system was installed. In doing so, you are maximizing the life span of the roof and ensuring a greater return on investment with lower maintenance costs.


  • Need Help? Contact a Roofing  Professional  Zero ObligationClear all debris off the roof (dirt, rocks, branches, leaves, etc…)
  • Clean out drains and gutters to ensure proper drainage can occur, preventing ponded water
  • Remove any overhanging tree branches or anything else that could penetrate the roof surface
  • Install walk pads in high traffic areas - especially around roof hatches and equipment systems
  • Inspect and insure all equipment is properly flashed and watertight
  • Inspect all areas for leaks and deterioration – pay attention to stains and discoloration of the roof edges and surrounding walls as they are possible indications of a leak
  • Take note of any trouble areas that could cause leaks, damage or deterioration and call your National Coating representative 800-423-9557 for further guidance.


Spending a small amount of time maintaining your roof every six months will help prevent costly repairs. These steps will ensure your roof a longer lifespan with less maintenance costs. Unfortunately, it is very easy to ignore preventative roof maintenance until it is too late. Small problems are easier and less expensive to solve but when left unnoticed, these small issues can lead to some of the most costly repairs your building will experience. Avoid costly roof repairs by using the checklist above every 6 months and immediately after large storms, high winds, hail and after other damage causing conditions.

Spring is a Great Time to Perform a Roof Inspection

Posted by Nicole Gale on Thu, Mar 12, 2015 @ 11:30 AM

checklistNational Coatings recommends doing a proper roof inspection twice a year – once in Spring, after the rainy season has ended, and again before Winter begins. Springtime is a great time to begin fixing any issues your roof may have been experiencing in order to prolong the roof life of your existing building, allowing you to avoid a costly roof replacement.

It is very important to do a thorough roof inspection in order to properly maintain your roof, keeping it free from any major issues. Although the roof is often unseen and easily forgotten about, it provides the entire building and assets inside with protection from water penetration. During wintertime several issues can occur, causing abuse and problems to your roofing membrane that a roof inspection can catch, allowing you to maintain a properly functioning building.

We recommend completing the list below during your roof inspection to insure a proper and adequate roof assessment. 

1. Remove all debris from the roof. Pipes, skylights, pitch pans, HVAC units and other equipment are perfect gathering locations for debris. It is important to remove all the debris because it traps and holds water, which will promote roof deterioration at a faster rate.
2. Check all your drains. Make sure they are open and functioning properly. Test each drain by pouring water into them, a clogged drain could cause a leak.
3. Clear debris from all gutters.
4. Check your roof for any blistering and delamination. If you see these, we strongly recommend you contact National Coatings immediately for a professional roof inspection 800-423-9557.
5. Check the entire roof membrane for any signs of deterioration such as holes, mechanical abuse areas, defects, and/or separation at any seams and edges. If you see any of these failures, consider an ARM System now, so you don't have to replace and tear-off your roof later - this will save you thousands of dollars.
6. Carefully inspect junctures at wall and equipment base flashings and pipe penetrations.
7. Make sure sealant and caulking are in good tact.
8. Trim back any trees that hang over and are near your roof to avoid future unnecessary debris.

Once this inspection is complete, you will have a good idea of the current state your roof is in. If you feel you need to contact a roofing professional, we recommend not waiting as issues can spread and get worse, limiting your options for a roof restoration system.
