By the time water shows up on a ceiling, it has usually been inside the roof assembly for months. Insulation is wet, decking has started to soften, and what would have been a few hundred dollars in flashing work has quietly turned into a framing repair.
The good news is that roofs almost always warn you first. Here are the five signals we see most often on Central Texas homes, and what each one typically costs to fix now versus later.
1. Granules collecting in your gutters
Those mineral granules are your shingle's sunscreen. They shield the asphalt underneath from ultraviolet radiation, and when they wash away the asphalt starts to cook. A handful of granules after a new roof is installed is normal manufacturing shed. Ongoing granule loss on a roof that is eight years or older is not.
Look in your downspout splash blocks after a heavy rain. If you see what looks like coarse black sand accumulating, the roof is aging faster than the calendar suggests.
Cost of acting now: a rejuvenation treatment or targeted repair. Cost of waiting: a full replacement two to five years earlier than necessary.
2. Rust, gaps or caulk at the flashing
Flashing is the metal that seals the joints where the roof meets something else: chimneys, walls, skylights, pipe penetrations. Most leaks we diagnose are flashing leaks, not shingle leaks. If you can see rust streaks, lifted edges, or a previous repair where someone smeared roofing cement over the problem, water is finding its way in.
Caulk is not flashing. When we find a roof "sealed" with a tube of black goo, we know the actual detail underneath was never rebuilt.
Cost of acting now: a few hundred dollars per detail. Cost of waiting: rotted decking and interior drywall, often $2,000–$6,000.
3. A roofline that is no longer straight
Stand across the street and sight down the ridge. It should be a straight line. Any dip, wave or visible sag means the decking or structure beneath has taken on moisture and lost strength, or that the roof is carrying more layers than it was designed for.
This is the one sign on this list that is never cosmetic. A sagging roofline is a structural symptom and it does not reverse on its own.
Cost of acting now: deck replacement in the affected area during a re-roof. Cost of waiting: rafter and truss repair, which turns a roofing job into a carpentry job.
4. Daylight, dark streaks or damp insulation in the attic
Your attic is the honest witness. On a bright day, turn off the lights and look up: pinpoints of daylight mean holes. Dark streaking on the underside of the decking means water has been running down it. Insulation that is matted or compressed in one area has been getting wet repeatedly.
While you are up there, check whether your bathroom exhaust fans vent through the roof or simply dump humid air into the attic. We find the latter constantly, and it destroys decking from the inside out.
Cost of acting now: repair plus ventilation correction. Cost of waiting: mold remediation on top of everything else.
5. Bruises, dents and lifted shingles after a storm
Hail damage is genuinely hard to see from the ground. What you can check are the soft metal surfaces at ground level and just above it: gutters, downspouts, air conditioner fins, mailboxes and window screens. If those are dimpled, the roof took the same beating.
Wind damage is easier to spot: shingles lifted at the edges, missing tabs, or a shingle line that no longer sits flat. Once a shingle's seal strip is broken, that shingle will keep lifting in every future storm even if it looks fine today.
Cost of acting now: often nothing out of pocket, if a claim is filed within your carrier's window. Cost of waiting: a denied claim because the damage can no longer be tied to a specific storm date.
What to do with this list
Walk your property this weekend with these five items in mind. You do not need to get on the roof. From the ground, the gutters and the attic you can catch most of what matters.
If you spot even one of them, get eyes on the roof before the next storm season. Our inspections are free and come with photographs of what we find, whether or not there is work to sell. Some of the most useful inspections we do end with us telling a homeowner their roof has another five good years in it.
