We have installed these screens for many of our clients and eliminated the hassle and costs of having their eavestroughs cleaned twice a year to prevent overflow of eavestrough and potential water damage to the home. The Smart ScreenTM screens come in 6 foot length pieces and are easy to install. Simply screw them down onto the conventional eavestroughs using 3/8” or 5/8” screws in the fabricated holes. This system is very affordale, they retail for about $10 per piece. We have encountered many other leaf screen systems which simply do not work. These ones do. We highly recommend that you get these screens installed when have your roof replaced by us. They are also available at select stores such as Canadian Tire, Home Hardware and Lowe’s should you wish to install them yourself. Install them and be glad you did when the fall rolls around.
