McCollum, Crowley,Moschet&Miller,LTD <br /> Project BL-Ob-01304 <br /> January 25, 2007 <br /> Page 4 <br /> Conclusions <br /> Due to the variety of details and direction in some of the limited ability to get to the roof areas wilhoul <br /> damaging roof tiles, we feel it wiIl be necessary to do repair wark based upon a starting point where we <br /> fecl it is highly probable therc is damage and continue radiating out fi-om that location until the areas are <br /> known to be solid and c�y. We marked on a set of elevations witt� a yellow highlighter,those areas <br /> believed to be the tnast likely to have daulage. These are the initial areas where repair work needs to take <br /> place. In addition,we have highlighted i1i red, areas that are potential questions and shoutd require <br /> additional probing while the crews are on site, to detei-niine if indecd damage is taking place. <br /> The scope of work that we see taking place includes the following: � <br /> ■ Removal and repair of stucco in the yellow highlighted areas on the attached elevations. <br /> ■ Investigation continues at areas indicated by the red highlighter on the elevations. <br /> • Repair damage to the cracked and broken clay tiles _ <br /> • Sea1 any penetrations, including windows and doors,pipes,conduits and the intersection between <br /> frieze boards and the stucco areas. <br /> • Develop corrective activity for the top of the sheet metal flashings and the attachments of the <br /> handrails. We recommend a�vaterproof inembrane be placed over the top of this metal aud <br /> possible covered with another section to protect it for long-ternl duration. Additional weeps <br /> should be provided to drain water that falls out of the splash joints on the�vp of the metal. <br /> Additional areas need to be investigated where previous leakage l�as occurred to determine whether it is <br /> the same mechanism of damages noted outside tlle mudroom and joist space for the garage noted in test <br /> cut number 6. "I'hese areas are dry indicating not much moisture,if any,is getting into these areas, <br /> leading us to believe that this is a possibitity of previous damage that occurred when there was problems <br /> with the roof originally. Following that logic,we would recommend we investigate further areas where <br /> the same situatzon could occur, and correct thosc areas even though it may be reading as a dry conditioii <br /> on the infrareds and other moisture probes today. <br /> There are windows at the boys bedroom and batl�room a�ld the girls room indicating significant damage to <br /> the��indows. In thesc cascs, wc recommend the removal of the windows and replacement and <br /> investigation of the underlying sill conditions as those windows also are indicating potential damage to <br /> the wall. In particular,the east wall family room windows which are doubte casement units as noted in <br /> the areas of test cut number 4, it is possible water is entering between the mullions of the Marvin <br /> windows and tracing down behind the building paper. In these areas tl�e building paper is also reverse <br /> lapped over the flange and not sealed providing a path for water to enter. We assume these same details <br /> are occurring on many of the other windows around the perimeter of the home where there are flat wall <br /> areas. Therefore,we recotnmend cutting the sills and doing a surgical repair in these areas to get proper <br /> lap of the building paper and scalant, as well as repair any of the expected damage. <br /> It is my feeling that there will be some areas of sheathing damage, however,the indications that the , <br /> majority of this project plywood sheathing,there will be damp areas which can be either dried out or <br /> replaced,but that the structural damage will uot probably extend into the home other than areas that have <br /> had long-term leakage. � <br />
