After reading the “Chinese Drywall” article I learned that in humid climates Chinese drywall can emit an odor of sulfur or a smell of rotten eggs. I also learned that exposed wiring will appear corroded or dark. Since I am moving my business from Tennessee to Florida, I found this article to be extremely useful.
TILE ROOFS, AS SHOWN IN THE ENCLOSED PHOTO, CAN BE EXPENSIVE TO INSTALL. WHILE THEY LAST LONGER THAN AN ASPHALT SINGLE ROOF, THAY ARE SUBJECT TO HIGHER REPAIR COSTS AFTER A MAJOR STORM. THE OWNER OF THE PROPERTY WILL HAVE TO “WEIGH” THE VARIABLES TO DETERMINE IF THE EXPENSE IS WORTH THE EXTRA COST.
The tile roof as shown in the gallery picture is very similar to the picture submitted for this exercise. These roofs are popular for their life span and durability, provided there are no trees overhanging the roof. These roofs are suseptable to wind blown debris in a storm.

Fiber Cement Tiles
FIBER-CEMENT TILES
Fiber-cement tiles were originally made by mixing asbestos fibers with cementitious mixtures
that usually included Portland cement and sand.
Asbestos fibers were a health hazard came legislation that eventually prevented the use of asbestos fibers in many products, including fiber-cement roofing tiles. They have properties similar to concrete tiles.

Dryer Vents
Clothes dryers evaporate the water from wet clothing by blowing hot air past them while they tumble inside a spinning drum. Heat is provided by an electrical heating element or gas burner. Some heavy garment loads can contain more than a gallon of water which, during the drying process, will become airborne water vapor and leave the dryer and home through an exhaust duct (more commonly known as a dryer vent).
The roof was walked and inspected from the surface. At time of inspection it was noted that damaged/cracked tile(s) were present on the left hip over the garage. This should be repaired to prevent water intrusion. A licensed roofer should be consulted for further evaluation.
There was evidence of overheating in Aluminum branch circuit wiring that was used in the years from 1965 through 1973. Due to the escalating prices of copper, many branch wiring’s were accomplished by using the Aluminum. Poor connections will cause wiring to overheat in outlets, lights and fixtures.
In Oklahoma it is very rare to see a tile roof. I have inspected only a few in my career. The picture I included in this post is of the bird stop that needs some slight adjustment. A minor repair but one needed nonetheless.
Mastering Roof Inspections: Tile Roofs, Part 1 is the article that I read to go along specifically with this course. One of the major points for me is due to my limited exposure to this type of roof, I will not walk them when I do come across one.
When conducting my inspection of this roof from the ground with binoculars I noticed that all drip edge, ridge vents, and vent stacks are fine. No damaged tiles were observed during this inspection. No defects were found during this inspection.
This picture shows a new roof construction in central Florida adopting Spanish Style concrete roof tiles. The sheathing to the roof has been covered with an underlayment with the correct two inch overlap for 4:14 Slope. In order to secure this type of tile (Interlocking) to the roof they are being directly nailed to the sheathing at the head of the tile.
Article: Mastering Roof Inspection: Tiled Roofs, Part 1
This article reiterates sections covered by the course indicating the types of tiles, their profiles and installation techniques, fire and hail ratings and types of bird stop used for tiles containing profiles. The article includes several illustrations provided in the course material.
Mastering Roof Inspection: Tile Roof, Part 1
Clay and concrete are the most common materials used for tile roofing. They come in many different styles and profiles: low, medium and high profiles with interlocking, overlapping and butting sytles. Most high or medium profile tiles need a birdstop which can be either created with mortar or be provided by the manufacture to fit. Clay and concrete tiles are wind resistant if installed correctly and are class A fire resistant also.
The straw roof is another roof that is witnessed from time to time in Florida, and this one is at the spot where the Hard Rock Hotel now sits in Dania Beach. These roofs are still being constructed, by Florida Indian tribes.
There are many different roofing materials offered in the state of Florida and one of the most popular is clay tile which is fastened to the roof using different types of fasteners. Often times, it’s the fasteners that determine the life cycle of the roof.
Not all roof structures are designed to carry the weight of cement or clay tiles. Before installing cement tile roofs it is important to allow the roof structure to adapt to the weight of the tiles, which is why the tiles in this photo were left on the roof before installation for several days to a couple of weeks. This allows the roof structure to flex before installation instead of after installation. Check with tile manufacturers or engineer before installation.
I am reporting on the following article: https://www.nachi.org/tile-roofs-part6-145.htm. I learned that tile roof covering requires flashing that is more complicated than the typical asphalt shingles. Based on this article I would say that it requires an experienced artist and a perfectionist.
Broken concrete tile - recommendation is to replace the broken tile immediately without delay by a certified roofing contractor. Cause of the broken tile is suspected and foot traffic in the past. It is the only broken tile during my visual inspection.
Mastering Roof Inspections: Tiles - During the articles in part 4 I discovered structural damage from the weight of the tiles inside the house. While it seems like an homeowner or an incompetent contractor installed the tile without taking into consideration of the weight thus having inside damage and probably drafter sag evident by the soffiet outside space from the exterior building. Recommendation will be a certified structural engineer to evalution the condition of the home.
