Having any amount of damage or exposed roof deck can completely compromise the effectiveness of water shedding from the shingles down to the underlayment.

This is a photo of a damaged roof. It has a 4:12 slope, and is covered by 3-tab asphalt shingles. Many of the shingles were damaged in a tropical storm, and have been repaired or replaced. The repair was done with shingles that do not match the original roof shingles.

Research & Writing Assignment:

In the article, "Roofing Underlayment types", the authors explain the different types of underlayment commonly used, and their proper installation. While the inspector is not required to identify the type of underlayment used, this article provides good background information to the inspector to better understand the roof components and proper use.

Inspection & Writing Assignment:

An apron flashing is typically used at the juncture of the top of a sloped roof and a vertical wall or chimney. This helps to make a water transition between the roof and the adjoining wall or chimney wall that the roof connects with.

Research & Writing Assignment:

Asphalt shingles must be driven through shingles straight and flush with the surface of the shingles. An inspector should also look for any fasteners that are crooked, driven too deep, or not driven far enough into the deck as these are all factors that could lead to premature failure of the roofing system.

Inspection & Writing Assignment:

In the attached photo, we can clearly see that there is significant sagging in the roof deck. This can be caused by several issues other than framing. Rotten or saturated sheathing can also cause roof lines to sag. This is the easiest problem to repair. If the framing is sound, and problems are not found elsewhere but the roof still sags, the problem might have originated because of poor installation of the plywood sheathing or shingles. When water penetrates through the shingles it causes the plywood to warp, weaken or rot, causing the roof to appear as if it's sagging between rafters.

Research & Writing Assignment:

There are three basic types of underlayment used beneath roofing materials:
asphalt-saturated felt, rubberized asphalt, and non-bitumen synthetic. The most common of these is asphalt-saturated felt. Its available in two thicknesses: 15-pound and 30-pound. Thirty-pound felt is much thicker and stiffer, and will last much longer, providing better protection.

Inspection & Writing Assignment:

Exposed sheathing can cause many problems for both the exterior and interior of a home. Water leakage can lead to ceiling spots or leaks, stains on interior walls, cracked paint, or peeling wallpaper. A quick inspection of the attic might uncover dark water stains on the rafters or in the insulation, or even light passing through holes in the roof. If left undetected, mold and mildew will develop in the walls, ceilings and insulation.

A sagging ceiling or roofline is another clue that there are major problems with a roofs decking and the roofing structure. Soaked or waterlogged decking can warp, which can lead to a bowed or wavy roofline and ceiling.

Inspection & Writing Assignment:

After taking this course, I went up and inspected my roof and found an exposed nail. There are a few things wrong with what I found. The first thing is the nail is exposed, which could lead to rusting, which it did. The problem with the nail be rusted is the integrity of the nail is compromised and could cause the shingle to pull away from the surface because it isn't being held in properly. The 2nd issue is the nail could break off and leave a hole or water could get around the nail, because it isn't properly sealed, and allow water to get under the shingle and possibly damage the underlayment or get into the attic of the house and provide moisture issues and damage to the insulation.

Research & Writing Assignment:

When I inspect the roof and perform the 10 steps of inspecting roofs, there is one inspection item that I see a lot of home inspectors either purposefully not perform, or not know they are supposed to perform, and that is checking the drip edge at the rake and eaves. You MUST remember that the drip edge at the rake goes OVER the underlayment and the drip edge at the eaves goes UNDER the underlayment. This is a very important check that needs to be performed on every roof inspection.

Inspection & Writing Assignment:

Roofing installation is just as important as the choice of materials utilized. Most roof covering failures are attributed to improper installation. Understanding the manufacturers installation recommendation will help guide the installer in the process and eliminate the potential for failure in the system.
