Downspout from gutter system used to redirect flow away from the buildings foundation is pictured. Appears to still terminate too close to foundation so a plastic extension was added. However, even with the extension this downspout will be dispersing much to close to the foundation and the flat earth around it. The noticeable lack of vegetation and erosion signs confirm this finding.

Through the images and diagrams provided in the NACHI gallery, I learned exactly how flashing and counter flashing should be attached/secured to a chimney. This is extremely important to the entire roof system as a whole as any object that extends through the roof needs to have the same water shedding properties as the shingles/tiles themselves.

I’m writing my essay on chimney flashing. Chimney flashing consists of head flashing which is located at the top side of the chimney where it meets the roof. If the chimney is more then 30" wide there should be a cricket. On each side of the chimney is step flashing and counter flashing. Counter flashing should at the top go into the brick mortar joint by 1". At the front side of the chimney the flashing is called the apron.

The above picture was taken while performing a roof inspection. While the overall condition of the roof was fair, there were a few locations where I noticed exposed fasteners along the ridge line. These fasteners have not been caulked/sealed and present a potential water entry point. I recommend sealing the fasteners with a water resistant caulk or consulting a qualified roofing contractor to make repairs.
In addition, when looking at the step flashing and counter flashing along the chimney we see another issue. The counter flashing was not cut into the masonry, and instead was affixed to the surface of the chimney with caulk that has split in multiple locations. While not a safety issue, this is another potential water entry point. I would recommend paying attention to this area and performing routine maintenance as needed (recaulking).

reffering to image https://www.nachi.org/gallery/?level=picture&id=919
I looked at the image showing the difference between a blister and hail damage. I live in an area that can get very hot as well as receive substantial hail from time to time. Understanding the difference in depth/ slop of the sides right off the bat should tell you whether its a blister or hail damage. If you still are not 100% sure, from the image I ascertained that a blister is much deeper and removes a greater portion of the asphalt covering, whereas hail does not penetrate the roof covering as deeply and compresses the mat and two asphalt coverings. Material is not removed from hail, so if you see the matting or that a larger portion of asphalt missing its most likely a blister.

I chose to take a picture of a clogged gutter. Upon inspection the gutter is obviously full of water and debris. The problem could be as simple clogged downspout or it could be the gutter has less than optimal grade at any rate it should be noted in a report and discussed with potential buyer about being inspected further by a licensed roofer.

I chose an article on asphalt shingles. the article specifically discussed how the mat was such an important element of shingle construction. for example: A shingle only makes up 2% of total weight of a shingle , but is a crucial part of determining impact resistance. Furthermore quality varies in asphalt itself and can effect performance especially in terms of hail damage. Also I learned that a crack has to extend through the mat not just the asphalt layer to be considered Functional damage.

When performing a roof covering inspection, it is important to look at the fasteners (nails). Fasteners head should lay on top of the asphalt shingles.
