10 Common Roof Repairs Every Homeowner Should Know About
Your roof is one of the most important parts of your home—it protects everything beneath it from the elements. But no matter how well it was built, all roofs are subject to wear and tear over time. Recognising common roofing issues early on can help prevent costly repairs and avoid structural damage.
At SC Roofing Olney, we’ve helped countless homeowners in Olney and across Buckinghamshire maintain and repair their roofs. In this post, we highlight 10 of the most common roof repairs every homeowner should be aware of, along with why prompt attention is essential.
1. Slipped or Missing Tiles
Strong winds, ageing materials, or poor installation can cause tiles or slates to become dislodged. Left unchecked, this can lead to water ingress and damage to the roof structure or interior ceilings.
Signs to look out for:
- Visible gaps in the roof covering
- Debris on the ground after storms
- Leaks following heavy rain
2. Leaking Roof Valleys
Valleys are the internal angles where two roof slopes meet. These areas are prone to water collection and can develop leaks if flashing becomes loose or deteriorates.
Why it matters:
Water can enter the roof space through failed valleys, leading to timber rot and damp patches inside the home.
3. Damaged Lead Flashing
Lead flashing seals joints around chimneys, walls, and roof edges. Over time, it can lift, crack, or corrode, especially in older properties.
Common issues include:
- Water staining on interior walls
- Visible cracks or gaps around chimneys
- Loose flashing visible from ground level
4. Blocked or Broken Gutters
While not technically part of the roof itself, gutters play a crucial role in directing water away. When blocked or broken, they can cause water to back up under roof edges or overflow down walls.
Maintenance tip:
Regular gutter cleaning—especially in autumn—helps prevent roofline and fascia damage.
5. Flat Roof Ponding and Leaks
Flat roofs are more prone to water pooling. Over time, standing water can degrade the roofing membrane and lead to leaks.
Common flat roof issues:
- Sagging or uneven surfaces
- Water pooling after rain
- Cracks in felt or membrane
6. Moss and Algae Growth
While moss may seem harmless, it retains moisture and can lift roof tiles. Over time, this can lead to tile damage and increase the risk of leaks.
Treatment recommendation:
Gentle removal and application of a roof-safe biocide can help keep moss at bay.
7. Roof Vent Damage
Roof vents regulate airflow in the attic and reduce moisture build-up. Cracked or dislodged vents can allow rain, pests, or debris into the roof space.
Key signs:
- Whistling sounds in windy conditions
- Visible cracks around vent housings
- Mould or damp smells in the loft
8. Flashing Around Velux Windows
If your home features Velux or skylight windows, proper sealing is essential. Flashing can degrade over time, especially if the window is regularly opened or cleaned.
Warning signs:
- Water drips from the window frame
- Rusting or staining around the frame
- Discolouration on surrounding plaster
9. Ridge Tile Deterioration
Ridge tiles run along the apex of a pitched roof. Mortar holding them in place can crack or loosen over time, posing a risk in high winds.
Inspection tip:
Look for uneven lines or visible movement at the top of the roof ridge.
10. Sagging Roof Structures
Sagging can result from a combination of ageing timbers, water damage, or structural shifts. It often requires urgent professional attention to prevent serious damage.
Indicators include:
- A visible dip or curve in the roofline
- Cracks in internal ceilings
- Doors sticking or shifting frames
