ONE: Whether you choose to go with asphalt shingles or a metal sheet product for your finished roof, roofing underlay can provide you with additional energy efficiency benefits. Underlay provides an additional layer of insulation that holds up even as shingles may start to crack and fray or deteriorate, while preventing air from escaping your home, or unwanted air from entering your home.


TWO: Roof Underlay helps prevent the risk of water or air infiltration to the roofing frame and decking.When you protect the deck of your roof (sheathing) you protect the wooden structure from damage caused by the elements, and mold.


THREE: With the increasing presence of tropical storms, hurricanes and turbulent weather in summer and winter, Winnipeg homeowners can gain an extra sense of peace from the fact that their home roof was well installed by a trained professional and has a properly installed underlay product to help protect from potential damages from such storms and inclement weather patterns.


FOUR: We all know how harsh the Winnipeg, Manitoba winter can be. Excess snow in sudden dumps, ice rain, sleet, building up in formations on your roof. The weight alone can threaten your roof to spring leaks, or water damage (and down the line mold). An underlayment product helps seal the frame of your roof and protect your home from increased damage.


FIVE: When selecting the right underlay for your roof be sure to consider the shape, the complications, and the slope of your roof as well as the Manitoba climate. An underlay is a must (in our opinion at Green Ladder Contractors) - but selecting the right one for your needs is equally important to consider creating the proper moisture and water barrier to protect you from any type of weather.


SIX: Application of a roof underlay to your roof replacement can also increase the fire protection of your home. If you are seeking to ensure your new roof complies with Class A Fire requirements - be sure to select an underlayment that holds the Canadian Standards Association (CSA) industry compliance rating.


SEVEN: Underlayment, of course, is not actually seen once your roof is finished - so you could well be wondering how roofing underlay adds to the curb appeal of your home. Well, in two ways: first, when seeing your new roof installation, neighbours, and future home buyers can rest assured that your home is properly protected on top - but more important to the curb appeal is the fact that underlay on your roof actually provides a more even, and uniform surface for your roofing product (shingle or steel) to install upon.
