How to Tell If Your Roof Needs Repair or Full Replacement
When your roof starts showing its age, it can be hard to know whether you’re due for a simple repair or if it’s time for a full replacement. In a place like Durham, Maine, where freezing winters, spring thaws, and summer storms take turns battering our homes, this decision matters more than ever. The good news? A few key signs can help you decide which direction to go—and save you from expensive surprises down the road.
1. Start With the Roof’s Age
Most asphalt roofs in Maine last between 20 and 30 years, depending on materials and maintenance. If your roof is approaching that age—or if you’re unsure when it was last replaced—it’s wise to schedule a professional inspection. Older shingles become brittle, lose their protective granules, and are more likely to crack or lift in our harsh coastal weather.
Tip: If your neighbors with homes built around the same time are replacing their roofs, it might be your turn next.
2. Check for Curling, Cracked, or Missing Shingles
Curling shingles are one of the first visible signs that your roof is deteriorating. They’re often caused by years of sun exposure and repeated freeze-thaw cycles.

Minor damage? A few missing or cracked shingles can often be repaired.
-
Widespread issues? If you’re seeing patches across multiple areas, replacement may be the smarter long-term investment.
3. Look for Granules in Your Gutters
If you notice dark specks collecting in your gutters or at your downspout, that’s your shingles shedding their protective coating. Once granules are gone, your roof is vulnerable to UV damage, leaks, and early failure.
This is one of the clearest indicators that your roof has entered its “replace soon” phase rather than “just repair.”
4. Watch for Leaks and Stains Indoors
A water spot on your ceiling or wall doesn’t always mean you need a whole new roof—but it’s never something to ignore.
In Durham’s humid climate, even small leaks can lead to mold growth or rotting roof decking. If leaks appear after heavy rain or melting snow, call a licensed roofing professional immediately to trace the source. Sometimes the fix is simple flashing repair—but persistent leaks are a strong sign your roof system is compromised.
5. Consider Energy Efficiency and Insulation
If your heating bills have crept up, the culprit might be your roof. Poor ventilation and insulation allow heat to escape in winter and trap hot air in summer. A replacement can improve energy efficiency and reduce your monthly costs—especially if you upgrade to modern, reflective shingles or metal roofing designed for Maine’s variable climate.
6. Evaluate Your Roof’s Structure
Sagging areas, soft spots, or uneven rooflines mean more than cosmetic issues—they’re structural red flags. Moisture can weaken the decking beneath your shingles, and once that happens, patching over the surface won’t solve the problem. A full replacement with new sheathing ensures your home stays safe and dry for decades to come.
7. Repairs Add Up—Know When to Stop Patching
If you’ve already had two or three repairs in the last few years, it might be more cost-effective to start fresh. Frequent repairs can quickly add up to the cost of a replacement—without the reliability of a new warranty.
