On the mititgation form, number 5 roof geometry: if i select Hip roof do i have to calculate the total roof system perimeter_____feet? do i use the measure tape to measure the size for each perimeter? :roll:
IF it’s all Hip I don’t measure, but if any part of the roof is different I measure so I don’t get called to talk about it. Yes use a 100 ft tape or a wheel.
As the Test Engineer for Wayne Dalton Fabric Sheild I can confirm that the product is tested for TAS 201, 202, and 203, and ASTM E 1886 and ASTM E 1996. When you see a product tested for TAS 201 it is 9 lb, there is no 4.5 test under TAS 201.
Concerning 4.5 missile systems in Florida, for shutters there are only a handful, Cameron Ashley made a steel panel system that was 4.5 rated, there are some pultruded fiberglass and polypropelyne shutters (colonial/bahama) that are 4.5 rated but not many other products. All of the fabric and screen systems are 9lb rated. There are a lot of impact glass windows/doors that are only 4.5 rated however and you have to watch for these carefully.
I would suggest that any roof that is being turned in as hip be measured unless you are supporting reinspection programs and don’t really care if your clients are inconvenienced by them.
There are spaces on the form to fill this information out when Hip is indicated, I would not leave these blank because it indicates that you may not have checked, regardless of photos. The perimeter measurement is taken on ethe very outer edge of all roof shapes, teh non hip shapes are any feature that is non-hip. E.g. flat roofs, gables, dormers, the sides of shed roofs, the slanted portions of clipped gables, mansards, etc…
Also remember that the entire perimeter of any roof system that is less than 2:12 is also considered non-hip. We see a lot of inspectors making this error on non structurally attached roof systems that are enclosed.
