Re-roofing with imitation slate in Lancaster Pa, is a less expensive option for a roof that looks like real slate and is acceptable in most every city for use in historic districts. Imitation slate also weighs less than real slate, which is a benefit for older homes with questionable roof structures. There are basically two companies that manufacture imitation slate, and both come with good warranties when installed by a certified installer. There is Eco-Star Majestic Slate by Carlisle and the Lamarite Slate Composite Shingles by Tamko. It is a personal choice as to which brand to install as both have very good warranties as well as similar characteristics.
Both brands come in various options such as color, width and style. If your home is a Victorian Style then perhaps the beveled, beaver tail or chiseled point from Eco-Star will your best choice. Keep in mind though, that whether you pick real slate or imitation slate, the snow will slide off fairly easily, so you should spend the money for the correct snow guards or come winter someone could get hurt. If you ever need to get onto your real slate roof you must be careful because of breakage, with composite or imitation slate there is no need to worry about breaking them, as they are unbreakable!
Which ever brand you wish to be installed on your home, make certain the installer follows closely to the manufactures installation instructions and you will have a roof that will last and look great for many years.
