Knowing when to replace your roof isn’t always obvious, especially in Connecticut where weather plays such a big role in roof aging. Many Fairfield County homeowners are surprised to learn their roof is older than they thought — or that hidden issues have been slowly developing beneath the shingles.

Asphalt shingles generally last 15–30 years depending on the type, but CT's climate often shortens that range. Heavy rainfalls, salty coastal air, humidity, UV exposure, and temperature swings all accelerate shingle breakdown.

Granule loss is one of the biggest indicators. When granules start collecting in your gutters, it means the shingles are losing their protective surface. Dark streaking or moss on shingles also indicates moisture retention, which weakens roofing material over time.

Another sign is the roofline itself. If you notice slight sagging, dips, or uneven sections, the underlying decking might be compromised. This is especially common in older CT homes with long-term moisture exposure or inadequate ventilation.

Persistent leaks, multiple repairs within a short timeframe, and widespread shingle damage are also strong signs it’s time to consider replacement. One of the most overlooked indicators is the interior of your attic — stains, mildew smells, or damp insulation can all signal roofing issues that may require more than patchwork.

Aging roofs don’t always show their true condition until damage becomes significant, which is why professional evaluations are so important. A roofing expert can assess structural integrity, ventilation, shingle wear, flashing condition, and potential weak spots.
