What makes the difference ? Is it the number of nails ? The sealant on the three tabs ? Can you peal a roof off with SA underlayments with out taking the decking with it ? Is there any manufacturer who states a 110 three tab wind uplift in their Manufacture material ?
The way the Bubba's and Jose's around here install roofs, 3-tabs blow off at 10 mph. We had a straight line wind storm in 2001 that registered as high as 99 mph winds in the worst area, and i think half the roofs in the metro area had shinlges blow off. lol Most areas were 30-60 mph. :laugh:
If you tab these dont use just any black mammy. Me thinks you gotta use the modified. Ask Jack legg if you can find him, Arrrrgh.
They are a modified. Pick up a bundle of those guys and they are Heavy. Anybody hovering near this board who called himself a member of the (what was it?) four bundle club (?) did not qualify himself by packing four of those up a ladder. I guarantee that. They make a beautiful green one I put on a Russian Orthodox church. Lay down and stuck very very well. I'm sure the wind rating info must be on his site. 110 is a tall order though. Maybe I'll go and check just for fun.
"...Flexible and workable, the Hurricane shingle can be applied in temperatures down to 0°F (-18°C). Underwriters Laboratories tests prove that after two hours of sustained 110 mph (177 kph) winds, the Hurricane suffered no damage. Malarkey confidently backs these tests with a 100 mph (161 kph) wind warranty...."
Can't imagine any of the other guys beating that, but 110, highly improbable... maybe by special arrangement and with extra nailing & tabbing & supervision/inspection? If you can work that one out, please do us a favor and let us know what it entails.
