Signs that a Goffstown roof may need full replacement include: shingles older than 20 years, widespread granule loss in gutters, visible sagging, multiple active leak points, or more than 30% of shingles showing curling or cracking. If damage is isolated to one area and the rest of the roof is sound, a targeted repair may be sufficient. Master Roofers offers free inspections in Goffstown with a clear repair vs. replace recommendation and no pressure either way.
