One of the key components of a properly installed asphalt shingle roofing system is a secondary protective layer of underlayment.

IKO Synthetic Underlayments are perfectly suited for use with all IKO shingle products.  Choose either of IKO’s synthetic underlayment products to give your roof that secondary layer of protection, and give yourself complete peace of mind.

RoofGard-Cool Grey

RoofGard-Cool Grey, IKO’s original synthetic underlayment product, helped pioneer the synthetic underlayment market. IKO adapted all the experience gained from decades of manufacturing traditional underlayments to offer a product strong and reliable enough to be the foundation for today’s shingle installation.


Stormtite is IKO’s economical synthetic underlayment choice. Stronger than conventional organic felts, Stormtite installs easily, even in cool weather, due to its light weight. Stormtite is the perfect combination of strength and flexibility.
