Introduction

Look for visible signs of wear such as missing, curling, or cracked shingles, rust spots on metal panels, sagging areas, or persistent leaks after heavy rain. Inside the house, water stains on ceilings or in the attic, daylight showing through roof boards, or a musty smell can also indicate trouble. A professional inspection every year or two is the surest way to determine whether a targeted repair or a full replacement is the best solution.

Shingle roofs: Most manufacturers offer a 20–30 year limited warranty on materials, with workmanship coverage depending on the installer (often 5–10 years). Premium architectural shingles may carry extended 'lifetime' warranties if installed by a certified contractor. Metal roofs: Typically include a 30–50+ year manufacturer warranty on the panels and finish, plus a separate workmanship warranty from the installer. Some standing-seam systems offer paint or finish guarantees for 40 years or more.

Yes, in most cases homeowners can remain in the house throughout the project. Expect construction noise, occasional vibration, and restricted access around the work zone. If you have pets, small children, or sensitive schedules, plan for extra caution and communicate with the crew about safe entry and exit points. Only in rare cases—such as major structural work or asbestos removal—would temporary relocation be recommended.
