Advances in Fluid Applied Roofing

  1. 1. Washington Roofing & Insulation A Division of Washington Companies, Inc. Over 30 years of Experience in Polyurethane Spray Foam and Fluid-Applied Roof Coatings. Serving Kansas, Iowa, Missouri, Oklahoma and TexasCorporate Office: Kansas City Branch Office: Midwest Service Office:828 10th St - PO Box 1956 8224 Marshall Drive Claremore, OklahomaGreat Bend, KS 67530 Lenexa, KS 66214 Chuck Grubbs800-383-3062 - 620-792- 913-492-1577 918-606-22332430 fax 913-492-4362(fax) 620-792-2408
  3. 3. WHAT DO YOU EXPECT FROM A ROOF?• Leak Free• Durable• Cost-Effective• System Warranty• Ease of Maintenance• Sustainable
  4. 4. TRADITIONAL ROOFING PROCESSNatural Resources Manufacturing/Installation Roof Service Life $ $ Landfill
  5. 5. Roofing Tear-Offs – They take it from Here to There Where is There?
  6. 6. HOW ARE FLUID-APPLIED SYSTEMS SUSTAINABLE?Natural Resources Manufacturing/Installation Roof Service Life Sustain - Recycle Sustain - Recoat
  7. 7. THE KEYSFLUID-APPLIED SYSTEMS• Proven Performance• Higher Performance• Fully Sustainable• Ease of Installation• Ease of Maintenance
  8. 8. WHO ARE THE BEST CLIENTS?• Low Slope Commercial / Industrial / Institutional• Typically Own the Property for an Extended Period • National & International Corporations • Municipalities • Hospitals • Military • Multi-Facility Owners
  9. 9. WHY BUILDING OWNERS CHOOSE RESTORATION VS RE-ROOFING• Technical and Economic Benefits• Minimal Disruption During the Installation Process• Ease of Maintenance• Environmentally Friendly Systems• Hybrid systems available if restoration alone not possible
  10. 10. TECHNICAL BENEFITS• Liquid applied restorations provide a seamless system (seams are the weak points in any system)• Highly reflective (among the most reflective in the industry averaging 85%-90% reflectivity)• Cooler roof surface translates into Energy Savings & Cooler Interior• Resistant to Ponding Water (some can handle 72-hour standing water)• Easily renewed (Sustainable); easily repaired because material bonds to itself
  11. 11. EXPENSE LOWERING BENEFITS• Save on the initial system compared to most “conventional” application methods• Fully tax deductible as an operating expense, classified under maintenance• Lower utility expenses• Eliminate the expense of replacing the insulation• Economical maintenance• Long-term ROI improves due to lower cost of subsequent restorations
  12. 12. BUT WHITE ROOFS ARE ALL THE SAME. AREN’T THEY? • Overlays require a cover board; fasteners create thermal gaps reducing effectiveness of new insulation • Long-term SRI is better for high-performance coatings than for many sheet goods • Emissivity of coated roofs comparable to or better than sheet goods • Condensation point is not raised into roof assembly with restoration
  13. 13. DIFFERENT CHEMISTRIES IN ROOF COATINGS • Different chemistries impart different physicals • Appropriate uses vary • Differences in cost • Single component vs. multi-component
  14. 14. ACRYLICS THE GOOD THE BAD• Waterborne = low • Lowest tensile and VOC/odor, easy cleanup elongation (both > 400)• Inexpensive • Cannot handle standing• No solvents = reduced water bitumen bleed • Low chemical and impact• Single component resistance
  15. 15. URETHANESThere are two classes of urethanes: aromatic and aliphatic.Each has strengths and weaknesses. AROMATIC ALIPHATIC•Less expensive •Better UV resistance•Better elongation •High impact resistance/durable•Prone to chalking •High odor•High millage loss •High cost•May need accelerant in arid •Require catalyst, long cureclimates
  16. 16. SILICONESTHE GOOD THE BAD• High UV resistance • Loses physicals rapidly• Good initial physicals • Noncompatible with other• Single component systems • Prone to discoloration
  17. 17. SEBS THE GOOD THE BAD• Proven track record • Initial odor• Superior physicals, stability • Solvent cleanup• Chemical cure -- not • Higher cost dependent upon weather• Single component• Good resistance to chemicals and ponding
  18. 18. POLYUREASTHE GOOD THE BAD• Rapid cure under any • Plural component = high conditions margin for error• High solids • Improper mixing results in• Low odor inconsistencies • High cost
  19. 19. PMMATHE GOOD THE BAD• Short cure time • Poor chemical resistance• Resistant to ponding water • High cost• May be installed in wide • Strong odor during install range of temperatures • Lower adhesion strength
  20. 20. Chemistry lesson is over!!!
  21. 21. THE OBJECTIONS• This isn’t a finished roofing system.• These systems have to be field-assembled.• I don’t want to order caulking, sealants, etc. from multiple sources.• Fluid-applied systems can’t handle standing water.• This guy is an idiot and is selling us a line of bull.
  22. 22. THE OBJECTIONS • “We’ve all seen the failures.”
  23. 23. THE ADVANCES• Fibered mastics now offer one-step seam and curb detailing. Some manufacturers now offer a complete system including caulking, emulsions, etc.• There is no poly to tent or fishmouth. Random orientation of fibers means higher tensile strength and less sacrifice of elongation.• Factory reps now trained in infrared analyses, moisture probes, newer substrates, etc. We are a resource for specifiers and contractors alike.
  24. 24. THE ADVANCES AfterBefore
  25. 25. • Simplified systems • Less room for error • More competitive bids—less labor! • Quicker installation = reduced disruption • Waterborne and high-performance systems available • Quality control improved by single-source manufacturing
  26. 26. • Adhesion tests routinely done by manufacturers • In-house technical services• Better contractor education
  27. 27. ROOF RESTORATION—THE ADVANCES Existing Roof Detailed with MasticBase Coat Completed Sustainable Cool Roof
  29. 29. NEW CONSTRUCTION• Coatings provide renewable system• LEED points available• Benefits of monolithic system
  30. 30. LIFE CYCLE COSTS 100,000 SF – 30 YEARS• Single ply: $200k initial install + $250K overlay at 15 years + $350k re-roof at 30 years = $800k• Fluid-applied: $250k initial install + $125k recoat X 3 (every 10 years) = $625k It’s time to consider this option!
  31. 31. EXTERIOR ENVELOPE• Exterior Wall Restoration• CMU, Brick, Concrete, Stone, EIFS and more• Available in clear and color options• Options in waterborne and higher-performing materials
  32. 32. CONCRETE RESTORATION• Inhibits vapor drive through slab• Retards wear and provides stain resistance• Provides slip resistance when aggregate added• Possible uses: plaza decks, flooring, concrete roofs
  33. 33. FERROUS METAL RESTORATION• Superior Shore A hardness• Better chemical resistance than paint• Less respraying equals less down time—lower costs!
  34. 34. WHAT DO YOU EXPECT FROM A ROOF? •Leak Free •Durable •Long Lasting •Cost-Effective •System Warranty •Ease of Maintenance •Sustainable •Greatly Reduce Landfill Waste
