Storm-Ready Vinyl Roof Soffits

Bob looks at storm-ready features on the Punta Gorda house, starting with the front door that is outswinging with a stop to prevent blow-in. He also points out the impact-resistant glass that is being used throughout the house. Leslie Chapman-Henderson talks with Bob about soffit details that are being incorporated in the storm-ready house. The problem with poor soffits is that during a storm wind-driven rain and wind force their way up under the roof, into the attic where wind force attacks the structure and rain soaks the insulation and walls. In humid climates wet insulation and wallboard begin to grow mold within hours. Closing the soffit to penetration is not currently a code requirement but is critical to smart building in storm zones. Joe Breese from Alcoa shows Bob the vinyl soffit that is being used in the Punta Gorda house. The locking panel system means that wind will force the panels to grip tighter to one another rather than pull apart. The panels are connected to a j-channel that is attached to the wall. They are installed with 5/8-inch stub nails spaced every 16 inches. The soffit panels are cut to fit and stapled in place. There are no ventilation grilles evident on these vinyl panels. All air moves through the grooves in the panels to ventilate the roof and attic space. Still, these panels have about 80 percent more ventilation capacity than standard vinyl soffit panels.

Storm-Ready Vinyl Roof Soffits

" All right let's recap a couple of the features of our storm ready house like this door. Front door it swings out instead of in that needs it really has a stop behind it and high winds will not blow it in that's just a primer color it's going to be painted dark. Like the colors of the windows over here the other thing is the impact resistant glass that we have throughout the house and then of course the fact that all our exterior walls are solid structural walls are poured concrete. Leslie Chapman Henderson is with us again from flash I've -- and -- Now we are building this house so that it can withstand really bad storms and one of the last structural systems that hasn't been completed is the roof overhang. They the soffit detail as it's referred to."

" That's right we really beefed up the framing here because the because are largely silent on soffits so we had we seen a lot of failures in high wind events and -- get failure. The wind pushes up and the winter -- prostrate behind it in the immediate aftermath mold develops and all types of problems."

" Your insulation gets wet your ceilings collapse and it's a nightmare. Although I think there are two schools of thought right now about whether you have venting or no venting at all with some people like the idea of a totally enclosed. Attic system."

" That's right a lively debate is underway and I don't think we have all the answers there yet but in the Spirit of finding the right answers second debate will continue -- it."

" Well the debates. Have taken place over all the different elements of this beautiful red tile that's up there used to be put on the roof with just paddy of cement now we have to. Mechanical devices screws that fasten it to the plywood but anyway getting back to the soffit is aluminum."

" This is vinyl and this is -- priest or not how I judge all right Bob so. Vinyl is final but is also pretty flexible isn't that a problem when you're talking about high winds and and what about wind driven rain getting into the soffit well normally when people think about -- they think of aluminum soffit yeah and what we found is that. Vinyl soffit actually has a lot of a lot of advantages over aluminum soffit one of them being that it has this locking system on. So windy wind load this locking system this locking system where from one panel to the next -- they kind of come in and they lock together. Like that. Yet I -- yes. So what this actually what occurs when a wind load or any kind of load is placed upon this panel. It actually. Forces itself together and pulls itself together a lot like a lot like two hands gripping together OK so that's the thought and how is it actually applied up there as an attached to. Our soffit frame and to the house we -- Larry's doing right now is he's placed and AJ channel on the wall which he. That's basically this material here yes exactly yeah. -- attached that is actually is that with five eighths stub nails. And he's doing that about every sixteen inches along the wall all right. And now he's cutting them to shape. Now spreading --"

" And of course he's got a corner here so he's starting off with a 45 degree. Staples."

" Wanting this -- us about this soffit is that you really can't see any type of ventilation on the surface of it. Typically soffit has. Ten holes in it sometime of land things that allowed air to flow into it. What we've done with this panel we've actually hidden that ventilation. Up inside the grooves. And it gives it a real nice aesthetic but at the same time this panel actually has about 80% more ventilation than any kind of standard vinyl panel you find out there."

" All right we'll thank you Joe and Leslie great to see how many yards back and -- Todd Davison from FEMA and ask your questions."

Storm-Ready Building Features
Storm-Ready Building Features

Bob talks with Leslie Chapman-Henderson from FLASH about the storm-resistant features of the Punta Gorda house. The home is built of SWS — Solid Wall Systems — cast-in-place concrete walls that keep the home protected from impact and water penetration. It also has impact-resistant windows and patio doors to prevent penetration from flying debris, and an outswinging front door to resist blow-in. The home has a raised foundation and stem-wall construction to fight damage from storm surge. The roof goes beyond code with straps and clips that are embedded in the concrete structure during the pour to keep the roof tied down, extra thick 5/8-inch plywood sheathing rather than OSB, an extra moisture barrier, barrel tiles that are screwed into the substrate rather than mortered, and soffits that are reinforced and covered with a grill that resists wind penetration but allows heat from the roof to escape. Although code does not require storm-resistant soffits, Chapman-Henderson expects that to change after all of the soffit failures and water damage from Hurricane Charley. The garage door on this home is impact and wind-resistant with reinforced construction and heavy-duty tracks to prevent twisting, blow-in, and ultimate house failure during a high-wind event.

Building a Pitched Roof from the Ridge Beam and Rafters to the Shake Shingling

Bob opens the segment with a look at the Certainteed Landmark shingles selected for this project. Fabricated with a dragon's tooth angle, the Landmark shingles give the impression of a handsplit shake roof. Next Bob flashes back to the construction of the roof. Starting with the raising of the laminated veneer lumber (LVL) ridge beam onto the gable ends, Bob walks the viewer through the various steps in the process - laying out 20 foot 2 by 10s for the rafters, marking a ridge cut at the top of each rafter and a crow's foot at the bottom, positioning and securing the rafters to both sides of the ridge starting at the center, applying the CDX plywood sheathing followed by an ice and water barrier as underlayment for the first course of shingles, nailing on the aluminum drip edge, and finally laying out and applying the first course of shingles. Once the first course is finished, felt paper is stapled to the rest of the sheathing as underlayment. After the roofers have finished shingling all the way to the top, they add ridge vents and soffit vents to prevent moisture from building up under the shingles.
