Introduction
When it comes to roof maintenance, it’s often the smallest details that lead to the biggest problems. A missing tile, a minor leak, or some cracked flashing may not look serious—but give it time, and the consequences can be both costly and dangerous. Roofs are designed to be robust, but once their protective integrity is compromised, issues tend to escalate quickly.
At Sevenoaks Roofers, we’ve helped countless homeowners across Sevenoaks and Kent catch small problems before they turn into major structural headaches. In this article, we’ll highlight seven common roof repair issues that start subtly but, if ignored, can quickly spiral out of control.
1. Loose or Missing Tiles
A single loose tile might seem insignificant, especially if there’s no immediate leak. However, once one tile shifts or blows off, the surrounding tiles become vulnerable too. Rainwater can sneak underneath, leading to underlay damage, wood rot, and eventually interior water staining.
Over time, this seemingly minor defect can:
- Allow water ingress
- Compromise insulation
- Weaken roof battening
- Spread rapidly across a larger area
Prompt tile replacement keeps the rest of your roof stable and protected.
2. Small Roof Leaks
Leaks often start off as slow drips that go unnoticed in loft spaces. But water doesn’t stay still—it spreads through timber, plasterboard, and insulation. Before long, a drip becomes a stain, a stain becomes mould, and mould can lead to timber decay.
The danger is that:
- Leaks are hard to trace once they spread
- Moisture can hide in insulation and cause long-term issues
- Electrical systems may be affected if water enters cavity walls
Early leak detection and repair by Sevenoaks Roofers can prevent major internal repairs later.
3. Cracked Flashing
Flashing protects the most vulnerable joints on your roof—chimneys, valleys, skylights, and wall abutments. If flashing cracks or peels away, water will find its way in. It’s easy to overlook because the flashing isn’t always visible from ground level.
Poor flashing allows:
- Water to seep into structural joints
- Accelerated decay of timber and insulation
- Potential interior ceiling damage
Professional resealing or replacement is often quick and far less invasive than repairing long-term water damage.
4. Blocked Gutters
Clogged gutters might not seem like a roofing issue at first glance, but when rainwater can’t drain properly, it overflows and pools around the edges of your roof. This added moisture can seep into the fascia, soffits, or even under roof tiles.
Common consequences of neglected gutters include:
- Damp ingress into upper walls
- Fascia board rot
- Water pooling near the foundation
Routine cleaning ensures your roof can shed water efficiently in all weather conditions.
5. Moss and Algae Growth
Moss may look harmless, or even quaint, but it’s a clear sign your roof is retaining moisture. It commonly takes hold on shaded sections, feeding off water and debris. Over time, moss can lift tiles and clog drainage paths.
Unchecked growth can:
- Dislodge tiles
- Increase surface moisture retention
- Accelerate the breakdown of roof materials
Sevenoaks Roofers can safely remove moss without damaging the roof’s surface and apply preventative treatments to keep it clear.
6. Poor Ventilation
Good ventilation allows heat and moisture to escape from your loft or roof void. When blocked or poorly installed, it can trap warm, moist air—creating the perfect environment for condensation, mould, and eventually rot.
This can lead to:
- Timber weakening
- Mould patches in upper rooms
- Reduced insulation effectiveness
Adding or repairing roof vents can improve airflow and preserve structural integrity long-term.
7. Minor Structural Shifts
Subtle shifts in your roofline—caused by settling foundations, ageing materials, or extreme weather—may start with minor dips or sagging. But these shifts place extra stress on tiles, gutters, and internal supports.
You might notice:
- Slight bowing between rafters
- Uneven gutter lines
- Cracks forming near the eaves
Early inspection ensures that minor movement doesn’t turn into major roof restructuring.

Your roof is your home’s first line of defence, and the key to preserving it lies in proactive care.
