Modern RoofING – home improvement
The modern roofing home improvement project was inevitable and one of those projects you wished you didn’t have to do. The saddle around the parapet, if you could call it that, was installed incorrectly when the house was built, as a result, water was getting behind the siding. Also, the siding was not protected correctly, allowing water damage to occur to the fiber cement. More on that on the Siding project page. This was a must do home improvement project and one that I did not mind spending good money to correct.
If you are not familiar with a parapet, Wikipedia defines it as, a parapet is a barrier which is an extension of the wall at the edge of a roof, terrace, balcony, walkway or other structure. Here is a good image of a parapet and the saddle installation.
The biggest difference is we extended the saddle about an inch out from the wall of the house. The saddle also has a drip edge that adds another half inch. As a result, it keeps water off of the sides of the house. In the image below you can see that the old saddle is almost flush with the siding allowing water to run on to the siding. The new saddle straddles the entire width of the parapet, where the original one only extended half the distance on the parapet top. As a result, water would pool on the parapet and seep behind the so-called saddle.
A few words about fiber cement.
From the research I have done on fiber cement, failures are not very common, especially now. Even local suppliers were surprised by this. However, there is a class action lawsuit against James Hardie that stem from many of the issues that occurred about 2007 to 2009 time frame. Our house was built around 2008-2009. As it turns out the fiber cement lap siding had one coat of paint and the edges were not protected. They should have at the very least been primed. Many of the areas that should have been caulked, were not. So best practices were not followed. Below are a few images that show the damage the poor installation caused. I will discuss more about the siding in the Siding project page.
