![]() Why two ? Mainly because I wanted a second opinion. Thanks again for the comments and thanks GBR for all the links. I'll hire a pro to install them if that is something an amateur could easily mess up (but after all the $$ I spent so far on engineers I need to be sure it's really necessary!). ![]() The last remaining item to install is some type of ties. I have already implemented some of the suggestions from their reports but will avoid going into details (unless someone really wants to know). In an older home where settling has occurred I'm guessing it's even harder to really figure out what is going on. They can't magically see where all the stresses are in a structure. #1 recommended using 2X6s where #2 thought 1X6s would do. Engineer #1 and #2 both recommended collar ties that that were of the type that are located below the rafter peak. Engineer #2 needed to come back for a second visit after I pointed out that the location of the one of the main problem area was not properly identified. Engineer #1 totally missed some pretty obvious areas of concern that jumped right out for engineer #2. The green line represents where the structural engineer recommended installing another 16' long 2X4 horizontally to help prevent the wall spreading force.Ĭlick to expand. The red square is a closet which has cracks in ceiling and in the corners where the walls come together. The red lines indicate where the cracks are. Here is a partial diagram I created when I had too much spare time. One radical idea I heard was to somehow install trusses in the attic and then forget about ever using the attic for storage again. ![]() There are vertical 2X4s placed every 10 feet or so which help hold up the roof. The rafters and joists are all 2X6 with the exception of the area where the two roofs come together (i.e. To prevent wall spreading force their are flat 2X4s nailed across the joists which are in line with the rafters but not attached. So the joists do not create the bottom of a triangle with the rafters. The roof construction has ceiling joists that are perpendicular to the rafters. But that was torn off last year and I now have a much lighter new roof. A contributing factor could be having three layers of roofing. But it's pretty odd that this would start happening 60 years after the house was built. It's as though the foundation is settling. Some cracks are appearing in walls and ceilings. It's difficult to say what is going on in my house. I assumed this was to prevent the problem of wall spread. A structural engineer recommend collar ties.
