Our experts use high quality shingles, underlayment, tools, and proper PPE's when roofing on a customers home. If the pitch and slope is greater than the required limit we will tie down all personnel. Roofing starts with initial tare off, and replacing of any plywood to prevent future leaking. We will then lay down underlayment felt, that creates a water barrier, lay down drip edge flashing and rake flashing to prevent water from penetrating into the felt or plywood. And lastly we laser line all our chalk lines to ensure we create a perfect straight line for the shingle rows. We do haul all old shingles for a cost! A dumpster may have to dropped off in the nearest position for our crew members to dispose the old materials. Give us a call, and we won't disappoint! NorthWest Paintworks LLC.
