Technical Differences

Genesis roofs are different from the roofs of our competitors. A few of the differences are as follows:

Proper Preparations

Before starting, all grounds are secured. Tarpaulins and plywood are used to control garbage being removed from your roof. All loose wood is re-secured to the joists and damaged or rotten wood is replaced.


Genesis Roofing, Toronto Ontario Roofer, residential and commercial roofs, GTA, Richmond Hill, North York, Scarborough, Etobicoke, Missisauga, Brampton, MarkhamValleys are the channels on your roof where two roof slopes intersect. This is a critical area on your roof. Deteriorated or improperly laid valleys will result in a large volume of water entering your home. There are different methods of installing valleys as well as options on types of material used.

The most commonly used valley is a ninety pound mineral surface. This valley, if properly installed, is guaranteed by the manufacturer for only ten years. The lowest grade shingle is guaranteed by the manufacturer for twenty years. These products are not properly matched. This type of valley will not last the duration of the roof and will result in expensive service.

Another common practice is the closed valley technique. This is where there is no exposed water channel; the shingles overlap directly into valley. This is the cheapest and least time consuming method of installing a valley. The main disadvantages of installing this type of valley are two-fold: a) the shingles that overlap in the valley will deteriorate more rapidly due to the large volume of water flow and b) locating and repairing leaks are more difficult in this type of valley.

Many roofers are now using aluminum valleys. Aluminum valleys should not be used, due to their high rate of expansion and contraction. This over time, (one to two years), will cause the nails securing the valley to work loose resulting in a roof leak.

Genesis uses only pre-finished steel metal valleys. With metal valleys there are two options: the W-valley (more money but sheds water the best) or the standard straight valley. There are two main advantages of using the "W" style valley. First the raised center of the valley helps prevents backwash on heavy rains, (water running down the roof and under the low side of the valley, resulting in a leak). The raised center of the valley also picks up heat to help keep a water channel open in heavy ice conditions. This helps to reduce ice build-up in the winter.

Our valleys are all two ply, an ice and water shield underlay, (to deal with condensation on the bottom side of the valley in the cold months), then the steel metal valley on top, as required by the code. We then line our valleys. This helps to prevent leaking due to ice back up in the winter. The lining of the valleys makes them more pronounced, improving the aesthetics of the roof.

Our valleys are also tipped. This dramatically reduces the chances of leaking in heavy rains. Most roofers do not even know what a tipped valley is. Tipping is becoming a lost art. We perform numerous services each year, on other roofer's work, due to valleys not being tipped. These procedures as outlined above, add an average cost of approximately seventy-five dollars per valley to Genesis's cost. Extra materials used, and higher labour charges, result in more consideration given to a quality job. Again, you get what you pay for.


Genesis lines all gables. The result is more materials and labour used on your job. The main purpose of lining gables is that your roof will stand up better in high winds. The winds will be pushing on a total slope of your roof, instead of the individual tiles. This could eliminate costly repairs due to high winds. Lined gables also improve the aesthetics of a house due to the edges being straight, instead of jagged and curled.
