As one of the best-known brands in Canada, and one commonly seen across the United States, IKO's selection of roofing tiles is worth examining if you're in the process of renovating your home. IKO roof shingles are simple to install and effective while also being relatively inexpensive to purchase. Of the various lines of roofing shingles IKO produces, the Cambridge line, in particular, is notable for its wide variety of color options and ability to withstand winds of up to 130 miles per hour when properly upgraded. Installing Cambridge shingles can be done without much trouble so long as you follow the steps noted in the IKO roofing installation instructions provided with the shingles.
IKO Roof Shingles: Cambridge Series
IKO's Cambridge series of roofing shingles, which contain the standard Cambridge and Cambridge Cool Color sub-lines, are architectural roof shingles designed to provide solid roof protection while mimicking the appearance of genuine wood shakes. Shingles of this line are made of fiberglass cores surrounded by weathering asphalt and can be ordered in the larger "Advantage" size that makes installation significantly faster. While the Cambridge series of shingles is effective in most climates, the IKO Cambridge installation guide suggests installing the shingles on a warm day, ideally in the summer or spring when the sun is out. This will allow the various seals on the shingles to bind together properly.
Deck Preparation and Underlayment
To install your Cambridge shingles, first prepare your roof deck and eaves. The deck should be smooth, clean, dry and securely nailed, and the eaves should have metal drip edges and ice and water protection applied to them. Once this is complete, you can apply your preferred underlayment to the roof deck, horizontally with 2-inch side laps and 4-inch end laps. Trim the sheet to fit, and then move on to installing the roof flashing.
Flashing and First Courses
Flashing should be installed at any point where a roof meets a wall, another roof, a chimney or similar objects, according to your local building code. You should then install open metal valleys if possible and complete the valley flashing before installing the starter course of shingles. These should overhang the eaves and rake edge of your roof by roughly a quarter to three-fourths of an inch. With the starter course installed, you may proceed to the first course of shingles, layering them on top of the starter course. Trim 10 inches from the left end of the first course to determine your starting point for the second course of shingles, and repeat this process for each layer of shingles.
Finishing the Shingle Installation
When you've applied the final course of shingles, you may manually seal the shingles by applying a coat of roofing cement. Cambridge shingles will self-seal when they're warmed by the sun, but cool weather, high winds or blowing dust can limit the effectiveness of the seal. Roofing cement can mitigate this problem.
