When installing a metal roof, we use Class A leak barriers and synthetic underlayment. We also add snow guards to avoid any overflows. Freddy and Son Roofing will be able to guide you during your roof selection and answer all possible questions. Our installers receive constant training and are knowledgeable about the latest metal roof install techniques as well as products. We provide Metal Roofing Installation and Replacement Services in Virginia, Maryland, Washington D.C., and Pennsylvania.
