Introduction
Your roof is your home’s first line of defence against the elements, so knowing when it’s time for a replacement is crucial. But let’s face it — not everyone is equipped, trained or willing to climb a ladder and inspect their roof up close. Thankfully, there are plenty of signs you can spot from ground level or inside your home that may indicate your roof is nearing the end of its lifespan.
At Cotgrave Roofing Repairs, we regularly assist homeowners across Cotgrave and Nottingham who’ve spotted early warning signs without stepping a foot off the ground. If you’re wondering whether your roof is still doing its job or quietly letting you down, this guide will help you assess its condition safely and effectively — no ladders required.
1. Look for Sagging or Uneven Rooflines
A warped roofline often points to structural problems
One of the easiest ways to check your roof’s condition is to step back and look at its shape. From the pavement or garden, assess whether the ridge (the top line of the roof) appears straight and level.
Watch for:
- A dip or curve in the roof ridge
- Bulging areas or visible drooping
- Uneven lines along the eaves
Sagging can indicate problems with the roof’s supporting structure or long-term water damage — both of which may require a full replacement rather than a repair.
2. Check for Missing or Damaged Tiles
Gaps in your roof covering are a red flag
You don’t need to get up close to spot missing tiles or slates. Use binoculars or zoom in with your phone camera from ground level. Gaps in your roof allow moisture to seep in, leading to rot, mould, and insulation damage.
Signs to look for:
- Missing, cracked or sliding tiles
- Discolouration or darker patches
- Debris on the ground (bits of tiles or granules)
Consistent damage across multiple areas may suggest that your roof is no longer fit for purpose, rather than needing just a patch-up.
3. Inspect Guttering and Downpipes
Your gutters tell the story of what’s coming off your roof
Check your gutters for any signs of build-up, especially sand-like granules. These granules come from the protective surface of roof tiles, and a significant amount may suggest the tiles are degrading.
Other signs to notice:
- Gutters overflowing with debris
- Loose or sagging gutter brackets
- Signs of moss or algae staining on the fascias
At Cotgrave Roofing Repairs, we often find that faulty gutters are both a symptom and a cause of roofing issues — keeping an eye on them is an easy way to spot trouble early.
4. Observe Water Stains on Ceilings or Walls
Problems inside your home may begin above your head
Not all roofing issues show up outside. Water stains, damp patches, or peeling paint inside your home — especially on ceilings near external walls — can point to slow leaks in the roof.
Common indoor warning signs:
- Yellow or brown stains on ceilings
- Peeling paint or bubbling wallpaper
- Damp smell in upstairs rooms or loft areas
These indicators often appear after long spells of rain and shouldn’t be ignored, even if they seem minor.
5. Review the Age of Your Roof
Even good roofs don’t last forever
If your roof is over 20 years old and hasn’t had significant maintenance, it may be nearing the end of its natural life — especially if it was installed using older materials or under less stringent regulations.
Ask yourself:
- When was the roof last replaced or renovated?
- Have there been ongoing issues like minor leaks?
- Are your neighbours with similar homes also getting new roofs?
Roofs age differently depending on their exposure to the elements, ventilation, and installation quality. A roof that looks fine now could begin failing rapidly if it’s near the end of its expected lifespan.
6. Look Out for Moss and Algae Growth
More than just an eyesore
While moss might seem harmless, it can retain moisture, loosen tiles, and eventually damage the underlayment of your roof. If large patches of moss or algae are visible from the ground, particularly on north-facing slopes, it could signal long-term moisture retention.
Signs of concern include:
- Thick, spreading moss or algae patches
- Green streaks running down the roof surface
- Plants or weeds growing between tiles
These problems are often worsened by poor ventilation and could indicate underlying rot or damp within the roof layers.
