Goat Rails/Catwalk Replace mounting hardware

[Kurt Horvath]

Curt, Greg, et al, several months ago I recall you guys discussing redoing all the bolts that hold down everything on the roof, I seem to remember at a rally ???? Any way you guys described a Stainless fastener that is inserted into the newly drilled holes, then new bolts were screwed into the inserts. WOULD YA'LL REFRESH MY MEMORIE. I can't find the old posts. My coach was a Florida Coach and it's starting to show especially on the old roof hardware.

Kurt,

Below is the information that I saved, written by Rob Robinson.

11.14.2007 from Rob Robinson:

I rewrote the
procedures that I use for upgrading roof screws. Hopes this helps



All the Wanderlodge roofs that I have done have been late models (1993 on up).

In all cases each had the corrugated aluminium walkway material secured to the

roof with self-tapping ¼” tech screws. After several jobs I have modified my

original methods slightly but nothing significant. I remove the tech screws a

row at a time (3 or 4 screws). I replace them with hex head SS one-inch lag

screws. The major size SS lag screw I use is a 5/16”. In some cases where the

hole may have become enlarged or I screwed up and over torque I would use a

3/8” SS lag screw. To do a complete job you will need between 150 and 200 5/16”


SS lag screws. I would purchase an additional 20 or 30 of the larger 3/8” SS

lag screws to cover screw-ups and enlarged holes. Originally I would inject

each hole with polyurethane prior to screw insertion, but now I use windshield

butyl. This is the black stuff you can buy in rope form. I just pull off a

small piece and wind it on the threads of each lag screw. It does take more

time but in my opinion it provides a better and more flexible sealant and is

worth the effort. Also, in all the jobs I have done I have replaced the tech

screws that are found in the goat rail and it’s securing to the roof. The only

difference between the goat rail and the walkway upgrade is washers. Wherever a


lag screw contacts the goat rail I put a washer between it and the aluminium of


the goat rail. I now use power tools to remove and install but originally

started out with hand tools. I would do a few with hand tools, especially the

install, until I am familiar with the feel of the relatively thin roof steel.

Truth be known I only use a power tool to install the lag screws about half way


and finish the job by hand. I do use a power tool for removal.

Kurt, I outsourced. Rob spent several days on the hot tin roof. I now use the
rails and tread plate to hold flag stands.
