The document discusses considerations for commercial re-roofing projects. It outlines an evaluation process for assessing existing roof conditions by collecting data on the roof, looking for issues, imagining the roof's history and requirements, and making recommendations. It also notes that construction debris represents a third of US landfill waste and over 40% of US energy use is related to buildings.

11. Evaluation Process showing

12. Looking = Collecting

13. Looking = Collecting measure the roof, including walls and equipment

14. Looking = Collecting expansion joints

15. Looking = Collecting test cut roof cores

16. Seeing = Selecting

17. Seeing = Selecting history of roof system

18. Seeing = Selecting leaks

19. Seeing = Selecting roof problems

20. Imagining = Seeing what isn’t there

21. Imagining = Seeing what isn’t there warranties

22. Imagining = Seeing what isn’t there installation date

23. Imagining = Seeing what isn’t there manufacturer

24. Imagining = Seeing what isn’t there roof system requirements

25. Imagining = Seeing what isn’t there roof moisture survey

26. Showing = making it all clear

27. Showing = making it all clear brief description as to the condition

28. Showing = making it all clear recommend repairs

29. Showing = making it all clear recommend coating or re-cover

30. Showing = making it all clear recommend replacement

31. Showing = making it all clear estimated remaining service life

32. Showing = making it all clear estimated probable cost

33. Showing = making it all clear provide priority levels

34. Design Process

35. cants/curbs/nailers/flashing

36. penetrations and edge details

37. slope/drainage

38. deck

39. codes

40. expansion/movement

41. vapor drive

42. insulation

43. wind uplift resistance

44. fire rating

45. moisture control/vapor drive

46. work area access

47. material handling

48. As much as 90 percent of all water intrusion problems occur within 1 percent of the total building exterior surface area.
