  1. no quote function for me to reply. By hurricane straps, did you mean the wall to roof hardware? That's vital. yes Metal panel isn't rated, as far as I know, but the high wind building methods that I've seen place it above all shingle style roof covers. Don't install it on top of a previous shingle roof, especially in your Florida climate, moisture gets trapped in the shingle layer and corrodes the metal panel from the bottom on up. Expose the underside of the metal panels to the attic if reasonably possible. that scares me. I need double or triple protection from leaks. like pe
  2. 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 planking with 8D ring shank nails. Might use peel and stick. Then Id like a metal roof, although I might go shingle. I dont have a lot of money, but i do want the strongest roof possible. I want my home to withstand the next big one that comes thru. Is metal really that much stronger and

  5. 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 for the best reasonably priced outdoor concrete screws for use in central florida. thanks, pa?
  6. 8000 lbs per cable per rafter why? what is ultimate load?
  7. None, but I've only seen 3 wood buildings with sag and bow. All three garages. When a hurricane strikes, they will blow away. I plan on being here and intact after the storm. My ridge bow is about 3".
  8. ...769 pounds so cable rated at 1k every rafter would do?
  9. what is wrong with my math? I never got a value that low. So how many cables would that be? Every rafter?
  10. 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 roof does not have much sag and the walls have no apparent bow. However, Im adding hurricane straps, supports for the gable ends, and extra fasteners to hold the roof planking to the rafters. Vertical rafter supports and then a new roof cover too. So, I decided to add the rafter and collar ties too.
  11. I cant understand this math. ive been over and over it. Each time I get a little further, then I loose it again. ref: How to calculate rafter thrust? -Help! at http://www.eng-tips.com/viewthread.cfm?qid=105386 Can someone help me figure cable load? 4/12 24" rafter spacing. No rafter ties at all. A few existing collar ties. ceiling joists run parallel to ridge. house is 27' x 30'(ridge). 7/8" roof planking and asphalt shingles. thanks, pa
  12. I've decided to add rafter ties to my home. Im thinking of using cable. 1952 house. This house was built with NO rafter ties and very few collar ties. Block construction. The joists run from gable to gable. With the nakid eye the ridge is not sagging, walls are not bowing. However, I have added hurricane straps and gable supports. Soon, i will be replacing the roof and while at it, screwing the roof planking to the rafters. Im making my home as hurricane resistant as possible. Therefor I have also decided to add cable rafter ties and 2x6 collar ties. suggestions? pa
