The NY State Residential Code mandates ice and water shield at roof eaves — a self-adhering membrane applied from the eave edge to at least 24 inches inside the exterior wall line. Rochester's lake-effect climate produces average annual snowfall of 90–100 inches and ground snow loads of approximately 40 psf, making ice dams a near-annual occurrence. Ice and water shield is the primary defence against water infiltration during ice dam events. Verify this product is explicitly included in any contractor's quoted scope before signing.
Slate roofs are common on Rochester's historic Victorians and colonials — specialist slate contractors who can assess repair vs. replacement are worth engaging before committing to full replacement. Properties in Preservation Districts may need a COA if changing from historic slate or wood shingles — contact the Preservation Office before selecting replacement material.
