![]() So, if cost savings and payback time are your primary concern, check with your insurance agent first for the approximate dollar savings for the upgrade. Upgrading the connection means you roof is much less likely to blow off or suffer severe damage in a hurricane, and what that additional level of safety for your home and your family is worth to you.Īlthough the maximum discount allowed for roof-to-wall connections is about 35%, it can be much less-depending on the insurance company and the other hurricane-resistant details of your home. But the second factor is the hurricane-resistance of your house. The first is the number of years it will take for the insurance discount to pay back how much you spent, which may be more than a decade in some cases. ![]() Is the cost worth it? There are two factors to consider. The price can vary between $1,000 and $4,000-plus. The fix can be as simple as adding a third nail to each truss or rafter connection in the attic, or as complicated as having to remove the soffit all around the house and installing new connectors from outside, then replacing the soffit. It is possible to do a retrofit and upgrade the connections to get the discount and there are contractors around Florida that specialize in it. So if it doesn’t meet all these standards, even if only at one or two locations, the discount is voided and the inspector must mark the connection as equivalent to toe nailed. The inspector must rate it based on the weakest connection. No visible severe corrosion of the connectors.Less than 1/2” sideways gap between connection points.The connector must be attached to the truss or rafter with a minimum of three nails. ![]() A metal connector clip or strap must be installed from the wall to every truss or rafter.When you have a wood roof structure like most homes, then it must meet the following four criteria for the discount: See our blog post What does toe-nailing mean? if you are not familiar with the term. But it does indicate that the roof structure connection is inadequate by today’s standards. It does not necessarily mean that your roof has been toe-nailed to the wall below, although most pre-1960 houses are done that way. It appears the best solution is to build interior walls ½” below the ceiling framing line, then use a Simpson Strongtie STC roof truss clip which keeps the trusses in alignment, while allowing for vertical movement of the roof truss.īy the use of drywall clips to attach the edges of the drywall and holding the first drywall screw back from the edges of the gypsum wallboard, allow the sheetrock to flex and minimizes the possibilities of cracking the drywall joints.You lose a big discount-up to 35% off your windstorm insurance cost-if the inspector marks the box for Toe Nails on Section 4 - Roof To Wall Attachment of Florida's wind mitigation inspection form ( Uniform Mitigation Verification Inspection Form, OIR-B1-1802). I now have more than my share of cracked drywall joints due to variances in contraction and expansion.Ī Hansen Pole Buildings’ client recently asked about how we recommend attaching interior walls to trusses – even knowing our post frame building kit packages typically the exterior shells only, no interior walls. We have very few interior walls, however those which are full height had the truss bottom chords nailed to them. I’ve got some of them in our home in South Dakota, compounded by the slight deflection in the 48 foot span floor trusses. Well, it turns out there are some potential issues. Prefabricated trusses were still relatively new and were most generally treated like rafters and ceiling joists had been in hand stacked roofs. ![]() This included all of the non-load bearing interior walls as well as the exterior.īack in the 70’s (before most of you were born) not much consideration was given, in stick frame construction, to varying degrees of expansion and contraction of different components. When I worked for Dad and the uncles as a teenager, it was Uncle Gil who would go out on Saturdays and mark all of the top plates, in preparation for Monday morning’s roof truss deliveries. Seemingly Uncle Gil was just as at home and comfortable walking walls 50 feet in the air, as most of us are walking around our houses. Dad would tell stories of Gil walking up beams set at an 8/12 roof slope and swore Gil was part cat. My dad was the oldest, and I cannot begin to count the number of times he spoke highly of his younger brother Gil’s abilities to walk up nearly anything. My long time readers have heard the stories of my framing contractor father and uncles.
