Using Roof Ties to Secure a Roof Against Hurricane Uplift

Randy Shackelford of Simpson Strong-Tie joins Bob on site at the storm-ready house in Punta Gorda, Florida. Shackelford looks at an assortment of ties for new and retrofit applications with masonry, trusses, girders, and joists. He starts with the embedded truss anchors that were wet set four inches deep in the poured concrete walls. As the trusses are positioned, a truss anchor wraps around and is nailed to each truss, tying it directly into the reinforced walls of the house. When Bob questions retrofit applications, Shackelford shows him a specially developed truss anchor that is screwed into existing masonry before being wrapped around and nailed to the trusses. He also shows Bob basic truss anchors that are designed to combat up to 1,500 pounds of wind uplift and heavy girder connectors that can carry as much as 5,000 pounds in wind loads.

" This is rainy -- heard from citizens there attack -- any good to meet you right I think team so I know your company's been making metal connectors and parts for many many years but. We've got a whole assortment of things in my truck here from the perspective of how we make this roof system. -- probably the most common excuse in this else's. Embedded truss anchor. Yeah they're pouring these concrete walls right they stick that in about four inches six and when they deliver the trusses. They wrap it over the trusses so he's just an end to his next assessment of -- Salem. And of course we've got those at every single point along the perimeter of the house where a roof member comes into contact with. But I lost one of these trusses have truss -- great. Now can these be used that are going to retrofit situations really -- today disease can say it has been put him into the concrete when it's being poured. So we can't make some other connectors that can be gazed. Once the house once the concrete is already poured and they serve all the different -- they don't stick into the concrete and stand. You would drill holes in the concrete and use these masonry stories question those holes like Batman in this -- And -- this. Or if you don't have a house with trusses you just have joists and and roof rafters you can still use this great -- these things cost. Probably envelope or dollar debt -- Now this looks to all the world like just a joist hanger right. But this is actually a heavy truss hanger and there's a couple of things in this elsewhere using this type of truss hanger because it has these slant nails. And these nails give the connection a lot of uplift resistance to I see through each one of these reverberations here you can nail at a slant. Tony so it connects the team had similar very similar to reduce got to allow a lot more holes -- Kansas -- and is also be used in masonry. But there are other connectors and -- taste for example that's. Connector right here in -- it's got a concealed flange is it's hidden in case in an exposed location ICC back on the back porch OK that's also they would just -- and he's he's he's experienced. Ask. -- got him. Now what are these stretching things used so this -- yeah."

" Murder just connect. Or when the little trusses like we see him most of the south they -- have an idea now some 1500 pounds about it but. For a girder like we have over here which when this occurred as a double one. Right that's all -- there's lots of other trusses framing into it supports a much bigger area of the -- right and because of that it had them much bigger uplift force. Okay this type of connector can hold up to almost 5000 panels. About what this is also retrofit all sides not going to see this thing. It's all well well here we've got it since it installed in this situation obviously right at the end of this girt. Where the concrete wall and the place where it comes to rest upon it. Thanks Randy."

Repainting Masonry

Here are some things to keep in mind when you're painting masonry.Like any surface, masonry needs to be prepped thoroughly before repainting. Make sure any loose and flaking paint is removed, then coat with masonry conditioner. Wait twenty-four hours and then apply a coat of primer before your finish coat to ensure even coverage and a beautiful end result.

How to Level a Brick Path

Crushed stone and masonry dust work equally well when bringing a brick path back to level.

Wall Construction

There are three important concepts to remember for wind-resistant wall construction. Walls have to resist the uplift forces caused by the pull of the wind. Walls have to resist the shear forces that try to push the walls over. Walls have to resist the lateral force of the wind that tries to push the walls in and pull them away from the building. For uplift purposes, walls are the intermediate link between the roof and the foundation below. To resist uplift forces walls have to have a continuous load path that can be achieved through the use of metal connectors for wood frame construction or a combination of metal connectors, vertical and horizontal reinforcement, and a bond beam at the top of the wall for concrete masonry construction. Shearing forces Walls are also subjected to shearing forces that act in the direction the wind is blowing. As wind blows on a wall, the walls perpendicular to the wall the wind is blowing on, are subjected to these shearing forces and are called shear walls. Shear walls are inherently subjected to the shearing and sliding forces. Wood frame walls resist these shearing and sliding forces through the action of the wall studs, the wall sheathing (preferably plywood), and a specific nailing pattern. Concrete masonry walls resist these forces through a combination of concrete masonry units, mortar, and grouted and reinforced cells. As a result of the walls resisting the shearing forces and being fixed at the base, the walls are subjected to an overturning force, or the tendency to rotate over. For wood frame construction, this force is resisted through the use of a holdown or tensions tied down. Vertical reinforcement and grouted cells resist the overturning forces in concrete masonry construction. Wind Ready Walls Finally, walls have to be capable of supporting the push and pull from the wind. For wood frame construction, studs have to be sized and spaced accordingly to resist the lateral forces, and have to be securely supported at the top and bottom plates. Concrete masonry resists the lateral forces by using reinforcement in grouted cells.

Emergency Board Up

If your home is not protected by impact-resistant windows and doors; or impact resistant shutters or panels; consider building your own temporary emergency panels. Step One: Plan the Project. Count and measure each window and door that has glass including French doors, sliding glass doors as well as skylights. You might also want to include roof and gable end vents or any opening that if damaged would allow wind to enter your home. Measure each opening horizontally inside the exterior trim and vertically from the sill to the bottom of the top trim. Add eight inches to both the height and width to provide a four-inch overlap on all sides. When measuring a window with an extended sill measure from the top of the sill to the top of the window and add four inches instead of eight. Sheets of plywood are generally 4 feet by 8 feet. This will help determine how many sheets to buy. Be sure to purchase plywood that is 5/8 inch or greater, exterior grade (CDX). Step Two: Assemble Your Tools and Hardware. You will need a circular saw, drill and drill bits, hammer and wrench, work gloves and safety goggles for this project. You will also need an assortment of hardware including bolts, wood or masonry anchors, nuts and large washers. A range of bolts may be used because different bolts will be needed for wood frame versus masonry homes. Wood Homes use lag screws and plastic coated permanent anchors Masonry Homes use expansion bolts and galvanized permanent expansion anchors Step Three: Get Started Having someone help you with this project will make things a lot easier. First drill holes in the same diameter as the bolts or screws, 2-inches in from the edges of the plywood at each corner and at 12-inch intervals around the panel. Next hold the plywood firmly in place over the opening to mark where to drill mounting holes. If the window sill is flush to the wall, secure the plywood on all four sides. If the window sill extends out at the bottom, secure the plywood on the top and sides. For windows 3 feet by 4 feet or smaller installed on a wood frame house, use 1/4-inch lag screws and plastic coated permanent anchors. The lag screws should penetrate the wall and frame surrounding the window at least 1 3/4 inches. For larger windows, use 3/8-inch lag screws that penetrate the wall and frame surrounding the window at least 2 1/2 inches. For windows 3 feet by 4 feet or smaller installed on a masonry house, use 1/4 inch expansion bolts and galvanized permanent expansion anchors. The expansion bolts should penetrate the wall at least 1 1/2 inches. For larger windows, use 3/8-inch expansion bolts that penetrate the wall at least 1 1/2 inches. If a window or door is larger than a sheet of plywood, you will need to join the panels with 2X4 bracing along the entire seam. Attach the 2X4s to the outside of the plywood panel with 10 gauge, 2 inch long galvanized screws (exterior deck screws) spaced every 4 inches. Use the widest side of the 2X4 to run the length of the entire seam. When youre done, mark each panel with the name of the opening so you will quickly know where to install it when a storm is approaching. Store the panels, washers and nuts together in a location away from the elements. Consider waterproofing the panels with paint or a sealant.
