Bob makes his fourth visit to the home in Norwell, Massachusetts, where an addition is being put on a Colonial home. The project has involved the use of insulated concrete forms, also known as ICFs, to construct the shell of the addition. ICFs are essentially foam building blocks that are filled with rebar and concrete to form the walls and the first-floor deck. Next the second floor deck was framed and sheathed with Georgia-Pacific Plytanium DryPly. The roof was sheathed with Georgia-Pacific Plytanium and faced with Deck-Armor as a breathable underlayment over the roof deck. The roof was put on the house in cold weather and there was concern about adhesion between the StormGuard and the roof deck. Deck-Armor eliminates the possibility of frost damage. The StormGuard was placed over the Deck-Armor and nailed into place. Metal roofing was purchased from MetalRoofingWholesalers.com and installed on the addition by a professional. Hal Martin of The Metal Men explains the features of the metal roof being installed. The roof is made of steel with an aluminum mix known as Gavalume. This roofing material offers stronger protection against rust, especially at the ends of the roof line. Galvalume is available in any size up to 40 feet. A ridge cap is put over the top of the installed panels to prevent rain and moisture from getting into the roof cap. Care must be taken installing the Galvalume panels because they are large, unwieldy, can bend and be scratched. More information
