Hello. I am very new to InterNACHI and I am completing my certification for the first time. I realize that I have a long road ahead of me, but I am thoroughly enjoying the course content so far and look forward to learning as much as I can. I completed my first course on how to inspect a roof. One of the final essays was to inspect a roof component. I will paste in the photo and my essay. I realized too late that I used the word Scaling instead of the word Spalling, but I think they have similar meanings at least.
Was my assessment of the counter flashing correct? I am having doubts.
The above image is of the chimney stack roof penetration. In this component of the roof system inspected the mortar on the chimney was suffering from heavy scaling. Some of the joints had no visible mortar. The Apron Flashing on the chimney stack was corroded and bent out of shape. The flashing was pushing shingles up and allowing moisture to penetrate. The counter flashing on the upward slope of chimney stack was installed incorrectly. The counter flashing was tucked into roof shingles promoting moisture penetration. Further evaluation by a qualified Mason/Roofer and correction is recommended.
That old lead flashing looks pretty good. I see no significant spalling. The shingles are not lifted as much as they are just lapped over the flashing (one shingle corner could use a little sealant) The moss/lichen type growth needs to be cleaned off because, over time, it can promote damage, but that is a maintenance issue.
Penetrate where? Did you see this penetration? I would make sure to get to chimney in the attic a double down on any leaks. But do not assume.
Finally, if you are writing a narrative for a report, consider making this just a few concise sentences.
The brick chimney mortar has spalling, the flashing is old and bent, and a few lifted shingles were observed. Further damage or leaking may occur. Recommend repair.
Thank you for the feedback. This is exactly what I was looking for. After I posted this I actually found a very similar post and realized it was lead flashing and that I was probably wrong.
Good stuff. Wanting correct information over being right is a necessary skill set, IMO.
Spalling is an important word that is a common issue. It is a result of a freeze thaw cycle that significantly effects masonry. My recommendation, do a deep dive into this and look for a examples near you.
Morning, William. Hope to find you well and welcome to the InterNACHI message board forum.
The above image is a protrusion. The chimney terminates outside. Something that protrudes, comes out of… a protuberance.
Degraded Or Mortar degradation although it does not look bad to me. The lichens/fungus/algae are what makes the masonry/mortar chimney appear degrading.
Flashing/counterflashing appear fantastic. Sealed in mortar. Lead.
Poor shingle chimney structure clearance. Both sides.
Observation: Single flue Masonry chimney.
Lite bed, head and butt joint mortar damage.
Lichens growth on masonry and flashings.
Poor shingle chimney sidewall clearance.
No adverse conditions observed the day of the inspection.
Recommend: A licensed masonry contractor further evaluate, clean and repair any damage therein.
Do not try to over think the structure. Objective, point out defects/deficiencies. Refer to a licensed professional to further evaluate and repair/replace.
Simple as that.
Excellent. Thank you for the feedback. Just so I understand correctly. The hole in the roofing material and the area around it is called the roof penetration? Whatever is going through that hole and above the roof is called a protuberance?
