This vent pipe is properly installed. The pipe has proper flashing,it’s under the shingles at the top of the flashing, and over the shingles at the bottom of the flashing. This prevents water from getting through the opening,and doesn’t allow water to penetrate through the roofs materials.
For this assignment, I went to the gallery and analyzed a picture that showed the difference between blistering and hail damage. The blistering takes most, or all of the ashpalt off the shingles, and shows part or all of the mat. When hail hits the roof, it doesn’t push the ashpalt out of the way, instead it compresses the top of the shinlge that could cause fracturing and allow moisture to get in through the fracture.
The article on asset protection brought many things into mind. It is critical to protect my personal assets and Family’s assets from the company assets either through Corporation protections or other forms of protection. It’s not cheap to go to court.
The drip edge at the edge of the overhang where it meets the fascia is doing its job. Even though there was debris on the roof and debris washing down it enabled it to down and save the fascia from staining and possible rot
Asphalt shingles elements are typically flat, rectangular shapes laid in courses from the bottom edge of the roof up with each succesive course overlapping the joints below.Shingles are made of various materials such as wood,slate, flagstone, fibre cement, metal, plastic.
An ice dam is aridge of ice that forms at the edge of a roof and prevents melting snow (water) from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage.
The roof in this picture has a small area of three tab shingles that exhibit signs of damage due to breaking. It appears there was not a solid line of adhesive in the area of missing shingles. As a result, this damage could have potentially stemmed from a high wind event.
Hail storms can cause significant damage to property. The cost of repairing hail damage in the United States averages about $1 billion annually. According to the Insurance Information Institute, for every $100 of homeowner premiums collected by the insurance industry, $30 goes to paying for wind and hail damage.
Attached is a photo of missing shingles after some recent severe storms. A number of other shingles (which can not quite be seen in the photo) appeared to have folded over from wind with a defined crease at the top of the shingle and were not secured at the adhesive strip.
Summary of “‘Cool’ Energy-Efficient Roofs” - there is an increasing movement to utilize roof coverings that reflect UV light to reduce heat absorption. There have even been EPA Energy Star standards set that are roughly 2 - 10 times more efficient than standard type composition shingles.
I conducted this roof inspection from the roof. All aspects of roofing material are intact and funtioning properly. No visual evidence of cracking, torn, or missing shingles. The asphalt shingles on this roof all seem to be in working order.
For this assignment I chose to study a photo of an asphalt shingle roof from the inspection gallery. In the photo all shingles are intact and there are no missing shingles present in the photo. With out personally inspecting the roof I would be unable to adequately say this roof is functional.
The inspection of the home shows the roof in good condition at the time of inspection. I did find that the ridge cap shingles show some signs of loss of granules and will need to keep and eye on them for future replacement. also found vegetation from the palm trees rubbing on the roof this should be cut back for the health of the roof and to keep pests from using it as a way to get on the roof. While on the roof I found the gutters attaching the pool cage to the home were not clear so they should be cleaned out and remove the vegetation growing in them.
Asphalt Composition singles, there is two types of shingles out there fiberglass mat shingles and organic mat shingles that are no longer made. The fiberglass mat shingles are longer lasting and don’t break down as fast as the organic type which was made with a cellulose shingles base, The fiberglass works better for warm climates doesn’t absorb water and doesn’t buckle as much,making them more stable in warm or damp climates like Florida.
This photo is a classic example of a non-vented over lay roof. The main roof is on the rear - south facing side of a unheated garage. The screened in porch was added at a later date, after original construction onto a rear deck of the house. The rafter system of the porch roof was laid directly over the garage roof with a vented soffit. As seen from the attic of the garage there were no provisions put in place for the lay over roof to vent to the main ridge vent of the garage, aka roof sheathing cut to allow the porch roof to vent into the main garage attic area. The result of this lack of venting is the premature failure of the asphalt dimensional shingle. The south facing exposure of this roof is causing maximum UV exsposure, increased thermal cycling and excess heat build up that occurs in the unvented area, which is causing heat damage to the roofing shingles, the loss of volatiles. This area of the roof is at or near the end of its service life.
I chose to read the article " Mastering Roof Inspections part 8" variations among asphalt composition shingles. I am asked regularly if the shingles on a roof are good quality and or if the will last a long time. The information presented in the chart on test results from a independent lab following the ASTM standards is very helpful along with the information that compliance with the ASTM standards has been voluntary . This information will better assist me in answering these questions going forward. The fact that there is such a wide varying performance results and that for each type of shingle,i.e. 3 tab or dimensional - architectural shingles there is such a difference in the chemical make up as well is good back ground information to have in describing the life expectancy of shingles.
Organic shingles suffering from distortion due to loss of volatiles. As the volatiles dissipate, the cellulose mat becomes dryer and more absorbent. Because the volatiles have evaporated when moisture is added the shingles expand and distort. As a result, these shingle are near or at the end of their useful life.
Replacing damage shingle by breaking the bond and removing the fasters. Keep in mind replacing damage shingle on older roof may result in damage to surrounding shingles. Shingles need to be replaced for a number of reasons: blistering, improper stapling or bonding issues.
House raising is a lengthy process of separating a house from its foundation and temporarily raising it with hydraulic jacks. Houses are raised for the following reasons: to construct a basement, foundation is in need of repair, flood protection, to offset settling and to rotate structure for aesthetic purposes.
Hail damage is rated in terms of degrees of damage; bruising, granule loss, edge removal, wood spliting, and fracturing of the asphalt underlayment. Granular loss alone usually does not qualify for replacement of the roof.
Newer shingles obviously hold up better than older shingles, which have been subjected to natural elements a longer period of time.
Shingle damage is partly determined by the strength of the substrate below the shingle. A more structurally sound decking will not flex as much during impact, thus lessening the damage to the shingle.
