These tiles are made of cement. They have the same issues that clay tiles have when you consider installing them. In this case, there may be an additional concern. These tiles were made in 1931, which may mean that they have asbestos fibers in them. Using these fibers helped create a sturdy tile. The fibers can be released if the tiles are cracking.

Sunny days cause shadows. This photo shows the ridge detail for these same cement tiles. Tile roofs seem to experience problems on the ridges first in my experience. Some are cracked here. There were tiles missing from other ridges. Note: it is not safe to walk on tile roofs, so if you have a problem with one, it is best to leave the repair to a professional roofer.

This vent is starting to rust. Rust allows holes, which permits water to enter the attic. You would be surprised how much water can enter. What is also interesting here is that staples were used to fasten the flashing of the vent. Staples were also used for the shingles. This is not common, but staples should be treated like nails. You want to see them caulked. Rusting staples or nails can cause leaks too.

Skylights can be sources of leaks. This one has a good deal of caulking along the top flashing. Since the side is flat, it can hold water. A better design would be an upside down V to shed water from this area. The cable in the picture is for the television. Being loose, the cable can whip around in the wind, causing damage to the roof covering. These cables are often not secured to the home.

This may belong in the Wall section, but this is something you may not notice unless you are on the roof. A new wall covering was being installed onto the home. Here the installer has to be concerned about having proper flashing from wall to roof, and then install the siding panels to fit well in the space. Roof lines like this one make it hard to fit, so mistakes can be made. In this case, the installer has not completed the job.

Damaged composite shingles can have different problems, but as homeowners, we tend to concern ourselves with the larger picture (does the roof need to be replaced). This is a newly installed roof, so most shingles are in great shape. These shingles have most of the material removed in a small spot. This can lead to further problems with water damage. Roofers can be careless with the packages of the shingles where they cut into the shingle when removing the wrapping. In this case, the damage was probably due to either improper support system used when installing the roof (not using roof jacks) or a roofer walking on the roof with a cleat type shoe.

While on a downtown balcony, I snapped this photograph, because I found it inspiring. This roof brings a lot of interest to this building, and it is done in metal. We have a quansat semicircle roof passing through a stepped roof. Metal roofs can be energy efficient, and they can be interesting.
