Watch for curling, cracking, missing shingles, or a roof over 20 years old. Coastal Windows & Exteriors is a woman-owned GAF Master Elite roofing contractor serving 730+ towns across Massachusetts, New Hampshire and Maine. Since 2011, our family- run team has completed 7,000+ installations. Our crews confirm when [asphalt shingles](https://mycoastalwindows.com/roofing/) need replacing with a quick inspection. #### **What Winthrop Homeowners Need to Know:** * **Age matters most:** A roof past 20 years old often warrants a professional consultation about replacement, especially after coastal storm seasons. * **Inspect twice a year:** Plan a spring and fall check to catch granule loss, lifted shingles, and flashing gaps before they spread. * **Recurring leaks signal trouble:** Repeated water stains on ceilings usually mean the system has reached the end of its service life. * **Storm damage adds up:** Wind-lifted or torn shingles after a coastal storm leave the deck open to moisture and rot. * **Skylights are weak points:** Aging flashing around skylights leaks long before the field shingles fail, so check those seals first. ##### **Our Top Roofing Guidance:** **Best Overall:** A professional inspection for any roof past 20 years, since age is the strongest replacement signal. **Top Recommended:** Twice-yearly checks in spring and fall to catch small issues early. **Smart Third Step:** Prompt skylight reflashing, because seals fail long before the main roof does. A roof past two decades deserves a straight answer, not a guess. We’re happy to take a look and tell you whether a repair will hold!
