INSPECTOR THIS REPORT REFERS TO THE PROJECT: Roofing & Sheetmetal Orono Town Hall Orono, Ontario DATES OF INSPECTION: Aug. 13, 22, 1986. Introduction OF THE FOLLOWING: At the request of Mr. Joseph Caruana of the Corporation of The Town of Newcastle, Warnock Hersey Professional Services Ltd. conducted a visual examination of the roofing & sheetmetal on the above project. The purpose of the investigation was to determine and report upon the existing condition of the roof system and recommend various methods of replacement incorporating a minimum of insulation with an R -30 Yalue. Results of the visual examination: (First Option) The existing shingled roof system and ceiling cavity below were visually examined in order to confirm their method of construction and present conditions. The framing details were closely inspected to determine the feasibility of installing blown insulation and a vapour barrier within the ceiling cavity. It was confirmed that due to the structural members, various cross bracings and limited space that the vapour barrier could not be properly installed on top of the ceiling deck below the considered blown insulation without having numerous gaps permitting air infiltration,,it was therefore considered to create a flat substrate for the vapour barrier by installing an initial layer of 6 inches of fiberglas fill to the top of the existing roof joists, and then apply the vapour barrier on top of the insulation and mechanical fasten and caulk the vapour barrier to the top of the ceiling joists. Cont'd....... T1415 CERTIFICATE, OR REPORT, 15 VALID ONLY FOR THAT WORK WHICH WAS SPECIFICALLY REQUESTED, THE COMPANY IS NOT RESPONSIBLE FOR ANY VIEWS OR OPINIONS EXPRESSED BY EMPLOYEES PERFORMING THIS WORK WHICH FALL OUTSIDE THE EXACT TERMS OF REFERENCE, ALL CERTIFICATES AND /OR REPORTS ARE THE RESULT OF WORK PERFORMED IN CONFORMANCE WITH APPLICABLE SPECIFICATIONS AND STANDARDS TO THE BEST OF OUR ABILITY AND INTENT. HOWEVER, THE COMPANY WILL NOT BE RESPONSIBLE FOR DEVIATIONS WITHIN THE NORMAL LIMITS OF ACCURACY IN ACCORDANCE 0 WITH STANDARD PRACTICES. Warnock Hersey Professional Services Ltd. Page 2. Although this design is not a recommended practice within the insulation industry it is acceptable, if twice the amount of insulation is applied over the vapour barrier. This would give the system a total R -value of 52. Since the existing shingles are totally deteriorated they will require immediate replacement prior to the insulating of the ceiling. Should this methodology not be excepted it would cost in excess of $55,000 to reshingle and insulate the roof from the roof deck. Conclusions (Second Option) In order to insulate the ceiling from the roof deck, the existing shingles would have to be removed and additional wood blocking be installed on the wood roof deck. New ridge insulation would be mechanically fastened to the roof deck, over which new 2 inch plywood would be i- nstalled. Upon the completion of the above work, a new shingle roof could be applied. All cable ends would also have to be insulated and any openings within the ceiling cavity closed. Prior to the start of the above repair option a complete structural analysis would have to be completed to comfirm if the new loads introduced could be carried by the existing structure. Since the first option of remedial repairs will only introduce 12lbs /per square foot of additional loads to the existing structure we strongly recommend that the Town of Orono proceed with this option. Recommendations We presently recommend that the existing shingle roof be removed and replaced prior to the installation of the fiberglas blowing wool, vapour barrier and exhaust fans. The cost of the above would be as follows: Option No. 1 Item (1) The removal and replacement of'the shingles. Price $21,000 Dollars. i Item (2) The installation of blown fiberglas insulation and the vapour barrier Approx. Price $6000.00 Dollars. Item (3) The Installation of exhaust Fans and related vents. Approx. Price $4000.00 Dollars. Total estimated costs $31,000.00 (A 15% contingency should also be considered for wood deck replacement) Res ectfully Submitted, WARNOCK HERS Y PROF SSIONAL SERVICES LTD. Wayne Goe tzen Arch.
