Roofing in Florissant (63033)
63033 is Florissant's largest ZIP, covering neighborhoods on the south and east sides of the city. Housing is mostly from the 1950s through the 1970s — ranches, split-levels and two-stories — and many of these homes are due for their next full replacement at about the same time.
At 38 squares this home has close to 3,800 square feet of roof surface, well above the neighborhood average, with more ridge and valley length to detail.

GAF Timberline HDZ, installed over a full system
Timberline HDZ is GAF's best-known architectural shingle. Its wide nailing area (GAF calls it LayerLock and StrikeZone) is designed to make correct fastener placement easier. The peaks were finished with GAF Hip & Ridge cap.
Underneath: JBI synthetic underlayment on the full deck, Alco ice and water membrane at the eaves and valleys, a dedicated starter course at the eaves and rakes, and a continuous Lomanco Omni Roll ridge vent for attic exhaust.
