Most homeowners don't think about their roof until something goes wrong. Here are five signs to watch for — catch them early and you can save thousands.
When shingles start curling at the edges or buckling in the middle, it means the oils in the asphalt have dried out. The shingle can no longer lay flat and seal properly. This creates entry points for water.
What to do: This is an early-stage problem. Roof Maxx can restore flexibility and help curled shingles lay flat again. If left untreated, you'll eventually need replacement.
Those sandy granules on asphalt shingles aren't decorative — they protect the asphalt from UV rays. When they start coming off in your gutters, your shingles are losing their primary defense against the sun.
What to do: Some granule loss is normal on new roofs. On older roofs, it's a sign of aging. If you're losing granules consistently, get an inspection. Roof Maxx helps remaining granules adhere better.
Dark streaks on your roof are usually algae (Gloeocapsa magma). While not immediately harmful, they indicate moisture retention — a sign your shingles aren't shedding water as effectively as they should.
What to do: A professional inspection will determine if the discoloration is cosmetic or indicates deeper aging. Often, addressing the underlying shingle health resolves the issue.
Go into your attic on a sunny day. If you can see pinpoints of light through the roof boards, you have gaps that are letting in water, air, and pests.
What to do: This may indicate structural issues that need professional repair before any treatment. Schedule an inspection — we'll tell you exactly what you're dealing with.
In Ventura County's climate, a 15-year-old roof is entering the critical zone. Even if it looks fine from the ground, the oils in your shingles are depleting. This is actually the ideal time for Roof Maxx — treating proactively before problems start.
