Your roof protects your house from the damage of weather, loss of insulation, and structural problems and won’t last forever. Knowing the Top Signs You Need a New Roof Installation will help save you money on repairs and unexpected problems. The first sign—a clear one—is the age of your roof. Typical roofing materials like asphalt shingles last approximately twenty to twenty-five years; therefore, when your roof reaches or exceeds that age, start your process towards replacing it. Sagging spots in your roof could signify that there is structural damage, so you should consider addressing this as soon as possible. If you notice a build-up of granules from your roof shingles accumulating in gutters, this is an indication that your roof material is degrading. If you have increased energy bills, this could signify poor insulation of your roof and/or insufficient roof ventilation; these all are good indicators to consider replacing your roofing system.
