- Can Dektite be used over an asphalt built-up roof?
- How many SCOTS fasteners would it take to attach a #9 Dektite?
- Will Dektite work with a square pipe?
- What is the most common fastener for use with the Dektite?
- How much sealant is needed to install (5) #7 Dektites?
- Can Dektite be used to flash a pipe on a roof with a 25 degree pitch?
- Can Dektite be used over an asphalt built-up roof?
- Elastomers, such as EPDM, are not compatible with petroleum based materials.
- How many SCOTS fasteners would it take to attach a #9 Dektite?
- Based on a 1-1/2" recommended spacing between fasteners, and a 25" base diameter, it would take 50 total. The number of fasteners can be estimated by multiplying the Dektite base diameter by 2.
- Will Dektite work with a square pipe?

- What is the most common fastener for use with the Dektite?
- SCOTS Teks for attaching Dektite to a metal roof.
- How much sealant is needed to install (5) #7 Dektites?
- Use the following formula: The number of sealant tubes = (# of Dektites) x (Dektite base diameter) / 50. or (5) x (14") / 50 = 1.4 tubes.
- Can Dektite be used to flash a pipe on a roof with a 25 degree pitch?
- When used on roofs where pitch is steeper than 20 degrees, or when used on deep ribbed profile roof panel (1-1/2" deep corrugation or more). Consider using next larger size Dektite that will accommodate the same pipe diameter.
