Roofing - Cambridge Lt & Roofshake 40
IKO Cambridge LT laminated fibreglass asphalt shingles are the pinnacle of our Cambridge line, for performance and protection. Their extraordinary dimensional thickness creates a high-definition, natural “shake” look and profile. A double-layer construction of extra-heavy fibreglass mat (among the heaviest in the roofing industry) combined with a tough modified sealant provides superior strength, durability, wind and weather-resistance. Protection against unsightly algae streaks is built right in with our algae resistant granules. Thanks to their extra-large size, these shingles save on installation time, overall making them a very affordable choice for any home. Like yours.
IKO RoofShake 40 shingles are laminated to provide a remarkable dimensional thickness, not only for strength, durability, and weather resistance, but also to create an extraordinarily beautiful look for your home. RoofShake 40 is manufactured in a larger size with more exposure to create a high definition “shake” look for your roof. Its double layer construction, using an extra-heavy fibreglass mat and tough modified sealant, provides superior durability and wind resistance. All RoofShake 40 shingles are surprisingly affordable and are the perfect choice to protect and beautify your home.
