The honest version
Most homeowners call a roofer either because they see a stain on a ceiling or because a storm just came through and someone knocked on their door. Both are reasonable reasons to call. Neither automatically means you need a new roof.
Here's how to think about it before anybody gives you a number.
Signs that genuinely mean "replace"
- Granules filling the gutters. Those granules are the shingle's sunscreen. Once they're gone the asphalt underneath starts breaking down fast. A few after a new install is normal. A steady accumulation years in is not.
- Shingles curling or cupping across whole planes. One or two is a repair. A whole south-facing slope curling is the roof telling you it's done.
- Shingles that crack when you flex them. Brittle means the oils have cooked out. That roof will not survive another hail season well.
- Soft spots in the deck. If the roof feels spongy underfoot, water has been getting in for a while. That's structural, not cosmetic.
- Daylight through the roof boards. Go into the attic in the daytime with the lights off. If you can see daylight, you have an active opening.
- Multiple leaks in unrelated locations. One leak is a flashing detail. Three leaks in three different areas is a system failure.
Signs that usually mean "repair, don't replace"
- A single leak around one chimney, skylight, or vent pipe — that's almost always flashing, not the field of the roof.
- A handful of shingles blown off after a wind event, with the rest of the roof still flexible and well-covered.
- Moss or algae streaking on the north side. Ugly, treatable, not structural.
- A roof under fifteen years old with one localized problem.
Why attic ventilation matters more than the shingle brand
This is the part nobody explains at the kitchen table, and it's the thing that most determines whether your roof makes it to warranty.
A roof needs air moving in at the soffit and out at the ridge. When that airflow is blocked — insulation stuffed into the soffit vents, a ridge vent that was never cut open properly, bathroom fans dumping into the attic — heat and moisture get trapped against the underside of the deck. The shingles cook from below. They age from the inside out, and they do it faster than any sun exposure on top.
When we quote a roof, we look at the ventilation before we look at the shingles. If the last roof failed early, that's usually why, and putting an identical system back up without fixing it just buys you the same outcome again.
Do I need a permit to replace my roof?
In most Missouri municipalities we work in, a straight roof replacement does not require a permit — though the installation still has to meet code. Illinois is stricter and it varies by municipality; several Metro East villages do require one, posted on site with a final inspection.
The trades that almost always do need a permit are decks, fences, and patio covers inside city limits, which bring setback and height rules along with them. We confirm the current requirement with your town before every build rather than assuming. Each of our service area pages names the actual permitting authority for that town.
When we tell people to wait
We do it regularly. If your roof has real life left, we'll say so and put it in writing on the estimate. There's no version of this business where selling somebody a roof they didn't need works out — you get one bad review and a neighbor who tells the story for a decade.
If you want a straight answer, we do free inspections. You'll get photos of what we actually found, not a scare story.
