Signs You Need a New Roof: What to Look For in Murfreesboro
A roof rarely fails all at once. It gives you a couple of years of warnings first, and most of them are visible from the driveway or the attic hatch. Here is what to look for on a Murfreesboro roof, what each sign means, and which ones are just cosmetic.
First, know which clock your roof is on
The number printed on a shingle wrapper — 25, 30, 50 years — assumes mild sun and a careful installer. Neither applies to most of this city.
Builder-grade roofs, 2005–2020. Three-tab or entry architectural shingles, four nails, felt, plastic boots. In Middle Tennessee heat and spring wind, expect 12–18 years. A 2009 roof in Blackman is at the end now; a 2015 roof in Barfield is halfway.
Properly installed architectural roofs. Six nails, synthetic underlayment, membrane, metal boots. 20–25 years, sometimes more on a shaded slope.
Older roofs on the older streets. Around MTSU, downtown, along Old Fort Parkway — many are second or third roofs from the 1990s or 2000s and past 20 regardless of what is on them.
The signs, in rough order of seriousness
Granule loss
Look in the gutters and at the bottom of the downspouts. A layer of coarse black sand is the shingle surface washing off. Some loss is normal in the first year after installation; a steady supply after year ten is the roof wearing out. From the ground, bare or shiny black patches on the south and west slopes confirm it. Those slopes take the afternoon sun and wear first.
Curling and cupping
Shingle edges lifting at the corners (curling) or the middle of the tab dishing up (cupping). Both mean the asphalt has dried out and the shingle has shrunk. Curled edges are also where wind gets its grip, so a curling roof loses shingles in every squall line.
Cracking and thermal splitting
Straight cracks across shingles, usually in lines. Three months of 90-degree attic heat expands and contracts the shingle every day, and eventually the mat splits. Common on the three-tab builder roofs.
Nail pops in rows
Bumps in the shingle field, often in a line along a truss. Nails backing out lift the shingle above them, and water follows the shank. On its own this is a $250–$600 repair per slope; across the whole roof it means the deck is moving or the nails were driven high, and it is a sign the roof is on borrowed time.
Missing shingles after every storm
One shingle after a big storm is bad luck. Shingles after every storm means the seal strips have failed across the roof and every tab is loose. Replacement territory.
Soft spots
If a roofer walks the roof and it gives underfoot, the decking has been wet. If you can see the sag from the ground, the decking or the framing has been wet for a long time.
Daylight or water in the attic
Go up with a flashlight on a bright day. Any pinpoint of light through the deck, other than the ridge vent slot and the soffits, is a hole. Dark streaks on the underside of the OSB are old leaks. Our post on finding a leak from inside shows what to trace.
The signs that look bad but usually are not
Algae streaks. Black or dark green streaks running down the north slope. That is Gloeocapsa magma, a blue-green algae that grows on the limestone filler in shingles and thrives in Tennessee humidity. It is on half the roofs in town. It is ugly and it will shorten the shingle's life a little over decades, but a streaked twelve-year-old roof is not a failing roof. A soft wash removes it; a pressure washer removes the granules with it.
Moss. Same story on a heavily shaded slope under a big maple. Worth removing gently because it holds moisture, but not a replacement signal on its own.
A patch of new shingles that does not match. Just a repair that has not faded yet.
Attic heat. An attic over 130 degrees in July shortens shingle life, but the fix is ventilation, not a new roof. If the ridge vent was never cut through — common on new builds here — cutting it is $500–$900.
A 20-minute check you can do twice a year
Do this in spring and fall, and take the same photos each time so you can compare.
- Walk around the house with binoculars and photograph each slope from the same spot.
- Look at the ridge line for dips and at the rakes for lifted or missing shingles.
- Check the gutters and the splash blocks under the downspouts for granules.
- Look at the collar on every pipe through the roof.
- Check the ceilings in upstairs rooms and closets for new stains.
- Open the attic hatch and look for daylight, water trails and damp insulation.
Twenty minutes, two photos per slope, and a note of the date. When the signs start to show, you will see them change from one set of photos to the next.
Signs by house age
On a 2005–2020 house, the first signs are usually at the details: a stain near a bathroom from a cracked boot, a few tabs off the windward slope after a storm, or nail pops in a line. Granule loss comes later, often around year twelve.
On a 1985–2005 house, look for curling along the edges, bald patches on the south and west slopes, and any sign of two layers, which you can sometimes see at the drip edge.
On an older house, the shingles are only part of it. Look for sagging between rafters, a chimney with cracked mortar, and porch roofs that hold water.
Signs inside the house
Not every warning is on the roof. Upstairs rooms that are noticeably hotter than the rest of the house in summer can point to an attic that is not venting, which is also cooking the shingles. Peeling paint or a damp smell in an upstairs closet, a wet spot on the attic hatch cover, or a power bill that climbs each summer are all worth a look. None of them alone means a new roof, but each one is a reason to open the attic hatch.
Mistakes that cost money
- Replacing a roof for algae. It cleans off.
- Ignoring one sign because the roof looks fine from the street. Most failures are not visible from the street.
- Pressure-washing the roof. It strips granules and takes years off the shingles.
- Waiting for a leak to decide. By the time water shows on the ceiling, the decking above it has usually been wet for a while.
What to do with the count
| Signs present | What it usually means |
|---|---|
| Algae or moss only | Clean it, or ignore it |
| One of the serious signs, roof under 15 years | A repair, $300–$1,500 |
| Two serious signs, any age | Get it walked; plan for replacement inside two years |
| Three or more, or any soft decking | Replacement conversation now |
A written roof inspection is $150–$300, often credited back if the same contractor does the work, and it gives you a year count instead of a guess. If the answer is "three more years and fix the boots," that is what the report will say.
Common questions
How long does a roof last in Murfreesboro?
Builder-grade roofs from 2005–2020 typically last 12–18 years here. A properly installed architectural roof lasts 20–25. Metal lasts 40 years or more.
Can I see these signs without getting on the roof?
Most of them. Binoculars from the yard, a look in the gutters and a flashlight in the attic cover nearly everything on this list. Leave the walking to a contractor.
Does a new roof help when selling?
It removes an objection. Buyers and their inspectors look hard at roof age, and a roof near the end usually becomes a price cut or a repair request. A newer roof with paperwork keeps the roof out of the negotiation.
