For nearly every residential or commercial project, there is code language that states “install in accordance with manufacturer instructions.” This is for good reason. Manufacturer’s typically will comply with ASTM standards for materials and will submit installation methods to regions with expected harsh conditions.
Ever see a building product that mentions “Miami-Dade County” or “TDI” or “ICC-ES”? These markings indicate that the manufacturer has developed a method of installation that has been tested to meet the rigorous requirements of a particular location. These sets of instructions might tell you how to install, but they don’t tell you what not to do…
This might seem self explanatory to some, but when the manufacturer or local code specifies a certain screw or nail or recommends a coating, it’s probably a good idea to stick with the recommendation!
The above image shows a 5 year old fiber-cement siding installation where the contractor used electroplated galvanized screws versus the required hot-dipped galvanized screws. As you can see in the image the screws are all rusting and causing an eyesore on the surface of the siding. What’s even worse is that the screws are no longer holding the siding to the wall which creates an eventual falling and wind debris hazard!
Don’t let this happen to you! I’m a TDI Windstorm appointed engineer and I can help contractors make sure their project goes smoothly by ensuring the installation method and materials used are in compliance with manufacturers instructions and local codes. I can also help document conditions as shown in the image to help property owners ensure that they get quality installations that will add value to their property.
