The top and sides of the chimney are adequately flashed but no flashing exists on the 6ottom (north side); consider adding flashing on the bottom at the time of overlay if the chimney is to remain. ,. The wood burning stove chimney has a manufactured metal insulated chimney section in the attic and throu9h the penetration in the roof. Approximately 6" above the roof the chimney pipe returns to a single wall thickness. The use o'f a single wall pipe above the roof is not recommended practice (te�ds to cool and accumulate creosote more rapidly) but is allowed by code (contrary to report during the inspection). The chimney extends the more than the required 2' above the ridge line and has a satisfactory metal cap. The metal chimney flashing is satisfactory. Recommend the metal shield in the attic be positioned so that there is the required 2" separation.between the chimney and the insulation. L. The underside of the roof deck and the rafters are in satisfactory condition. Thou9h some water staining was noted, none of it appears to be recent. No sign of condensation, leaks or other damage was seen. M. The attic areas have approximately 13" of blown in insulation; the installers left a sheet showing their estimated the insulating value was R-27. R-30 is presently required by the Washington State Energy Code for homes heated with gas heat (R-38 for electric resistance heating). In layman's terms the R value is a measure the effectiveness of insulating material; the higher the number, the more effective the insulation. It does not appear that adding insulation would be cost effective. N. Recommend removing the antenna cable and roof connections prior to the next overlay. 0. In my opinion the wearing surface itself has 1-3 years of useful life with minimal maintenance. Cede allows two layers of asphalt composition tab shingles to be overlayed prior to removal of all composition shingles if the substrate (wearing surface, deck and structure) has not deteriorated si9nificantly. It appears that only one overlay has been installed on top of the original shingle. Prior to overlay9ng the "fish mouth" conditions (most noticeable on the south slope) should be cut so they lay flat and do not "telegraph" through the overlay. It is reasonable to anticipate "telegraphing" of most roof irregularities through an overlay. lJeiss Inspection Page 4
