This is a architectural shingle roof. it appears to be in good shape. There is just one layer of roofing material. The slope is 4:12 which adheres to the proper slope required by this type of roofing material. The fasteners appear to be good, and no exposed nail heads were noted. From the attic, I could see proper nailing into the sheathing. The sheathing was solid. The drip edge was in good condition. The closed valleys were in good shape. The flashing was also proper around the chimney and vents.
I’ve often wondered whether to write my reports in past or present tense. I was interested to read about which Nachi suggested to use. Past tense is used when talking of “turned on unit” or checked for blank…" Present is to be used more for things ongoing such as roof life expectancy, or current and ongoing grading issues.
Hello,
I’m writing about a roof inspection I performed recently. During my inspection, I found that the North side of the roof covering had some moss growth. As I proceeded into the attic area, I found that the same side of the roof had visible water damage on the roof sheathing. I took several photos and reported this as a defect and recommended that the roof covering be cleaned and that new sheathing should be installed by a licensed contractor.

Hello,
I’m writing about roofing. while there are many roof contractors in the world, not all are good. I found that some use improper nails and spacing. I’ve found many roofers ignore or forget about using flashing. Drip edges are found only on 70% of the homes and ice and snow under lament is a lot of the times not installed in colder climate areas. So that being said, you can never expect all standard roof practices to be the same form house to house.
Bill…
Drip edge and proper underlayment not present at several test areas. Recommend that these condition be corrected by a qualified professional to prevent leakage into the structure.
After reading several articles, I feel it would be a great “public service” to include “maintenance tips” and suggestions for homeowners and buyers to ensure a safe home.
Hello, I am completing the roof inspection course. I’ve been learning a lot about flashing especially at rakes and eaves. I’ve found on about 50% of my inspections the rake edge flashing is either missing or improperly installed including an inspection I did recently on a new build. Made recommendation to repair and builder complied. Thanks.

Good afternoon fellow NACHI Members. I have been doing inspections for a nearly 20 years and can’t help but notice that the ridge caps and especially the fasteners are installed incorrectly on almost 80% of the roofs I inspected.
I like to point out to clients that a proper ridge cap is doubled and the fasteners not seen. However, on many inspections the ridge caps are single layer and the fasteners are totally visible.
Below are two pictures of a metal roof. One side of the roof is showing more wear then the other from sun exposure. Metal roofs are painted with three different types of paint. The three main paint-type coatings used in the North American metal roofing industry are acrylic emulsions, polyesters and fluoropolymers.
Paint has microscopic holes that allows intrusion that encourages corrosion. Metal roofs should be inspected for defects and maintained in order for the roof to work properly.

Pictured here are 3-tab asphalt shingles. The shingles are installed on a 6 inch offset. The sloped is adequate for water runoff.
I researched how to become a HUD 203(k) Consultant. It’s a great way to add to your credentials. Here are the five steps simplified…
- Have 3 years experience as a general contractor of home inspector.
- Have proof home education.
- Have proof of licensing if required in your state.
- Have description of your ability to preform the inspections.
- Have proof of certification, verifying that you understand the requirements of HUD Handbook and all related materials listed in Mortgagee Letter.
Check out, https://www.nachi.org/203k-consultant.htm, for more detailed information.
I’m going to wait until I have some more InterNachi badges, but I am looking forward to applying.
A roof inspection on a house when a contractor dropped a hammer and it damaged the roof.
His fix was to caulk the hole.
This is unacceptable as the caulking will break down over time
In summary,
Reading the articular on efflorescence form the Library of inspections articular While " efflorescence is a harmless but unsightly accumulation of minerals on the surface of the masonry. Its presence indicates an excess of water, a situation that could lead to damage of the interior and encourage mold growth. Inspectors must know how to eliminate efflorescence surfaces and must educate their clients about its identification and its importance."

The article I read was “Mastering Roof Inspections: Attic Area Roof Inspection”. First thing you should be doing is wearing a respirator prior to entering the attic. Inspect all penetrations and look for moisture intrusion and apparent mold growth. Check for dark staining under roof sheathing or structural members. Use a moisture meter to confirm any suspected moisture.
This is a picture of a architectural asphalt shingle roof. The front of this structure has no penetrations. The front of this roof has two different slopes.
Here are a few picture I took while conducting an inspection. These are fairly common defects that I find. There is a cracked shingle, roof covering aggregate in the gutters and the plumbing roof jacks need new boots.
For my reading assignment I read “Mastering roof inspections” part 1 and 2. These articles are good reads and educational.
During our inspection of a roof, we could identify two different roof coverings. One was a roll sheeting and the second was a laminated architectural covering. Many areas of the penetration flashing were tarred over due to leaks. The roll flashing was delaminating and had gaps of a half of an inch, at the joint rafter of the addition.
My topic is penetration flashing. My picture is of 4 penetrating vent pipes and the flashing around them. I will disclaimer here that I did not go on the roof as there was no one else at the residence. The 4 penetrating pipes do appear to have flashing although one appears to be raised just slightly. I would inspect this area further when another person arrived at the residence.
My research was on chimney flashing. It is important when inspecting the flashing of a chimney that the counter flashing actually go into a groove in the chimney and then be sealed. Some people will only bend the top of flashing and put a sealant on it; the sealant will breakdown over time and in the elements. Always check the top of the counter flashing…
