im wondering why flags are even needed. maybe the UK is default, and I just did not notice, or did not care.

that was not me that put that flag there.

If your ele. fitting question was not a matter of codes, but you were just looking for opinions from some maybe knowledgeable people and you posted your question to 7 electrical sites, but hey you found an 8th in the States. might you not post there too? Likewise if some months later you had...

thanks

If you dont like reading threads by foreigners, then you might want to find a UK only forum. This forum allowed me to register and post questions. Some of which have been satisfactorily answered.

Why are rivets used to fasten gable rakes, sidewall flashing, and ridge caps? Would not self tapping screws be easier?

I think I found a better method. See image here http://imgur.com/a/qIoQl. Your thoughts?

Im going to install a gulfcoast supply versalok metal roof. This is a standing seam mechanically sealed hidden fastener roof approved for High Velocity Hurricane Zones (HVHZ), including Miami-Date. My goal is to hurricane proof my home with one of the strongest metal roofs available. I am also...

1200 sq ft house. built in 1952. Cinder block construction. Three 4/12 roofs. 5 miles inland from the west coast central FLORIDA. Im adding rafter and collar ties. Vertical rafter supports. gable end supports. Hurricane straps. Then I will hire someone to remove old shingle roof. Secure...

for outdoor humid, hot central florida. Strong structural concrete screws. Im attaching simposon H10S and LGT2 straps to my rafters and cinder block walls. Im using simpson screws to attach to the rafters, however simpson makes no outdoor concrete screws and has no suggestions. So, Im looking...

im not jacking the ridge.

I understand its not exact, which is why I would put a safety margin in the strength. 1600 is the highest suggested, so if I doubled or maybe tripled that, I should be safe. Heck, I might go with 7k lbs cables, just to be safe. My real issue is designing something to secure it to the rafters...

oops, i meant at every rafter or twice the strength cable at every other rafter. Now all I need to do is figure out the fastening.

thank you. If I understand correctly worst case is 1600, so if I installed a cable rated above 1600 at every other rafter, im then good, right?

[/url] I tried that site formula and i could not understand it enough to use it. I did post a question to that site, but got no real answer. See the last three posts. June 15, 2014 on. I actually asked for help and my complete post was on the site, now I see some of my post text was removed...

so cables to withstand 1200. How many cables?

50

I used 48 inches for "Height of Ridge above Plate" and 48" for Distance from Tie to Ridge so, in my math the tie is at wall plate.

Im planning on installing rafter ties in my 1952 cinder block home. It has no rafter ties at all. Every time Im in the attic and look around, I wonder what holds up my roof. The ceiling joists run parallel to the roof ridge. Im also going to install collar ties. Currently there are only two. The...

too blurry, so i cant read. I may not matter anyway. Since your asking if this would work. I dont know if it would work. I dont know if this formula would give me an accurate result. anyone else? Also collar ties are not meant to stop rafter spread. Does above formula factor in dead load...
