Roof Inspection
I inspected the roof of my house for this essay, and I found a lot of issues with it. Even though the roof is not older than ten years, it seems not to be in good condition. There are a lot of granulate material being wash off from the shingles. The shingles themselves seems to be ok, but some areas are discolored and chipped off.
There seems to be no problem with the fasteners and there were no signs of any popping up, but while inside the attic I also did not see any fasteners going thru the sheeting, but I also found out the there is a double sheeting. The slope of the roof is 4:12 and there was no access to see the underlayment. Ice barrier was not installed due to the tropical region were the house is located.
Dripping edges are in good condition and there is only one layer of shingles, also some areas of the fascia are deteriorating due to constant water contact. The pattern of the second layer of sheeting was not visible and impossible to determinate if it had any issues. The house does not have any roof valley. And all flashing were installed properly.
My topic for my research exercise on roof inspections is about asbestos. Mostly found in factories and shipyards. Also found in homes, in such places like asbestos roofing shingles and siding. Steam pipes, boilers, and furnace ducts can be insulated with an asbestos blanket or asbestos paper tape. Soundproof or decorative materials sprayed on walls and materials may include asbestos. Homes built in the 1930s to 1950 may have used asbestos in the insulation. Repair or removal is two ways to counter a asbestos material. Generally speaking if the material is in good shape, danger is way less. The cutting, sawing, sanding, scraping and degradation of the material leads to more asbestos fibers released. This is where the dangers of lung cancer derive from.
This image was taken from ground level and shows an asphalt 3-tab shingle roof in good shape. The drip edge is in a black finish installed over the underlayment on the rake and under on the eave. The aluminum gutter is installed to the facia and underneath the drip edge with a downspout visible. All appear to be in excellent condition.
Essay on engineered wood sheathing.
Engineered wood is any wood product that is not solid wood. Plywood and OSB are common examples and have changed home construction since their introduction. The cross-grain and laminate construction makes this type of wood very strong and durable. Primarily used for sub-floors and roof sheathing, it adds to the unit strength and is available as interior or exterior depending on it’s application.
Here we see a 3-tab shingle installation,after walking the roof found shingles to be secured and properly installed. Pictures below showing valley, hip and ridge all to be in good shape.
Hello Everyone,
One of the interesting things I learned about shingle type roofs, is that overlaying a rood on top of an existing roof is not recommended, but possible only if the existing roof is in decent condition. Also, the length of the nails used to lay the first roof, will most like not work for the second layer roof, they need to by longer. Thanks,
Hello Everyone,
The picture I took was taken on a commercial building. The building has a drainage running down the middle of the building. Notice the brown staining on the wall, this is a clear indication that the seal around the drain is leaking. and could possibly by leaking back into the building. I would make the recommendation that the owner hire a roofing contractor to inspect the drainage system and repair this issue. Thanks,
The below is written for an online course.
This picture depicts several issues.The first is that there is no roof covering extending past the fascia on both the front and side of the home. There are no gutters or downspouts as well. The lack of roof covering allowed water to penetrate behind the fascia warping it to the point that it pulled away from the house which lead to even more water working it’s way into the soffit. The roof sheathing is also now exposed and damaged due to water. The facia and soffit should be removed, any and all damaged material should be removed and replaced. The sheathing and roof covering should be replaced or repaired and a proper gutter and downspout system be installed.
My picture is of a residential gutter system. when I inspected closer I noticed there were no signs of a leak, I also noticed a gutter helmet has been installed. the grade goes downhill away from the house so no water is running back to the foundation. this one gets a passing grade…
Attic ventilation is very important for several reasons. The flow of air in an attic space removes excess moisture and heat from the attic which may lead to mold and higher than normal heating bills and heat loss. The addition of soffit vents, opposing gable vents and a ridge vent will allow air movement both in a convectional and wind assisted manner. It is imperative though to have the correct square feet of ventilation in relationship to the attic space needing ventilation.
The picture below is of an architectural shingle roof. This roof system has a ridge vent and soffit venting for the residence. Nails have popped up on several sections of the roof causing the lifting of shingles as seen in the picture.

After the roof inspection class I thought it would be wise to visit the Chimney Inspection section of the library. In my area we have a tremendous amount of improper flashed chimneys and insufficient structural support for the height of these chimneys considering the wind loads we experience. I will be visiting the proper code department for chimney construction to see what requirements are needed. I know we are not to conduct a structural evaluation of the chimney other than visible things wrong that could jeopardize the structural integrity. I know we are not code enforcers but it sure helps to know the code.

I chose chimney inspection: preventing collapse. Ive never given a lot of thought about a chimney being deadly until reading this article, I will definitely be making sure the chimney was properly installed and maintained from top to bottom, even checking for soil erosion.
The roof is Slate tiles with metal a one piece metal ridge cap. The slope of the roof is 8/12. This inspection was performed from the ground and from the eaves on an extension ladder. Some tiles have broken corners and repairs are visible, a few tiles a need to be replaced. The porch roof is Asphalt shingles with metal drip flashing no rake flashing was installed. The slope of the roof is a 2½/12. The shingles are installed correctly and all are in tact some cupping on the edges of the shingles are visible which is a sign for replacement.
Here is a picture of a damaged chimney. It can be seen as having crack in the chimney crown, causing a potential water penetration problem.
The crown is also not extended to prevent dripping problem
My research topic will be chimney height. The height of the chimney should be a minimum of 3 ft. It should be at least 2 ft higher then any part of the roof, within 10ft of the chimney.
Here is a couple pics at the eaves. The shingles are 3 tab asphalt that are in good condition. The drip plate is properly placed and the shingles overhang in the gutter. The gutters are fairly clean with no blockage.
Chimneys require maintains and can be potential water problems for home owners if the flashing isn’t installed properly or have been altered. If the chimney is greater than 30" a cricket needs to be in place to redirect water around the back. Step/ counter flashing needs to be installed on the sides and apron flashing on the front or downslope.
Writing assignment for How to perform Roof Inspectionscourse. During a roof inspection foundthat during an inspection on a new roof a flashing was not installed around aventing system. The home owner decidedto us tar to fix the problem. After a few years, the tar was alligating. Thiswas brought to the home owners attention for repairs.
