Quick answers from our roofing & siding experts
We recommend professional roof inspections twice a year—in spring and fall—plus after any major storm. Regular inspections can identify small issues before they become costly repairs, potentially saving you thousands of dollars. A typical inspection takes 30-60 minutes and costs $150-$400.
In Pennsylvania and New Jersey, roof replacement typically costs between $8,000 and $25,000 depending on roof size (1,500-3,000 sq ft), material choice, and complexity. Asphalt shingles cost $4-7/sq ft installed, while metal roofing runs $8-14/sq ft and slate $15-30/sq ft.
Signs you need full siding replacement include: warping or buckling across multiple areas, frequent repainting needs (every 2-3 years), high energy bills indicating poor insulation, visible rot or mold spreading, or damage covering more than 30% of the surface. If damage is localized to one area, repairs averaging $300-800 may be sufficient.
Yes, if your roof or siding sustained storm damage (hail, wind, fallen debris), file a claim within 30 days. Document all damage with dated photos from multiple angles, get a professional inspection report, and don't make permanent repairs before the adjuster visits. Most homeowner policies cover storm damage minus your deductible ($500-$2,500 typically).
Slate roofing lasts 75-150 years, making it the longest-lasting option. Metal roofing lasts 40-70 years, clay/concrete tiles 50-100 years, wood shakes 25-30 years, and asphalt shingles 20-30 years. Factor in your budget, home style, and local climate when choosing—longer lifespan often means lower lifetime cost.
A typical residential roof replacement takes 1-3 days for asphalt shingles on a standard home. Siding installation takes 1-2 weeks for a full house. Factors affecting timeline include home size, weather conditions, material type, and complexity (dormers, steep pitch, multiple stories). We always provide a detailed timeline before starting.
