When viewing a property, you may not be able to get up on the roof yourself, but there are several key signs to watch for.

1. Check for Missing or Damaged Roof Tiles
Why It Matters:
Missing or cracked tiles allow water to seep into the roof structure, leading to leaks and damp issues inside the home.
How to Inspect:
✔ Stand back and look at the roof from different angles—are there any gaps or damaged tiles?
✔ Look for uneven or sagging areas, which could indicate structural issues.
If you notice missing tiles, it’s best to get a professional roofer to assess whether it’s a simple fix or a sign of deeper problems.
2. Look for Signs of Leaks or Water Damage
Why It Matters:
A leaking roof can cause major structural damage, leading to costly repairs and health risks due to damp and mould growth.
How to Inspect:
✔ Check ceilings and walls inside the house for water stains, peeling paint, or damp patches.
✔ Inspect the loft or attic for damp insulation, rotting wood, or mould—these are clear signs of a roof leak.
If there are visible signs of water damage, it’s essential to hire a professional roofer for an in-depth inspection before proceeding with the purchase.
3. Inspect the Chimney and Lead Flashing
Why It Matters:
Chimneys are a common weak point in UK roofs, and damaged lead flashing (the seal around the chimney) can cause leaks.
How to Inspect:
✔ Look for cracks, loose bricks, or missing mortar in the chimney stack.
✔ Check if the lead flashing around the chimney is lifting or damaged—this can allow water to seep in.
Repointing a chimney or replacing lead flashing can be expensive, so ensure it’s in good condition before buying the property.
4. Assess the Gutters and Drainage System
Why It Matters:
Blocked or broken gutters can cause water to overflow, leading to damp walls, foundation damage, and roof deterioration.
How to Inspect:
✔ Look for cracked, sagging, or detached gutters.
✔ Check if downpipes are properly connected and directing water away from the house.
✔ Look for water stains on exterior walls, which can indicate overflowing gutters.
Fixing gutter issues is relatively simple, but if major water damage has occurred, it may require extensive repairs.
5. Examine the Roof’s Age and Material
Why It Matters:
Different roofing materials have different lifespans, and an ageing roof may require replacement soon after purchase.
How to Inspect:
✔ Ask the seller about the age of the roof and any recent repairs.
✔ Check if the roof is made of slate, clay tiles, or modern composite materials—each has a different lifespan.
A well-maintained slate roof can last over 100 years, while clay tiles last around 50 years. If the roof is near the end of its lifespan, factor in the cost of a replacement.
6. Ensure Proper Insulation and Ventilation
Why It Matters:
A poorly insulated roof leads to higher heating bills and potential condensation issues in the loft.
How to Inspect:
✔ Ask the seller or surveyor about the type of insulation in place.
✔ Check if the loft feels excessively damp or musty, which may indicate poor ventilation.
A roof with adequate insulation and ventilation will make the home more energy-efficient and comfortable.
Why You Should Hire a Professional Roofing Contractor
While a basic visual check is useful, a professional roofing survey is essential before purchasing a home. A trusted roofing contractor will:
✔ Identify hidden issues that aren’t visible from the ground.
✔ Provide a detailed report on the roof’s condition.
✔ Offer accurate cost estimates for any necessary repairs.
✔ Help you negotiate repairs or a lower price with the seller.
Choosing a Quality Roofing Contractor
When hiring a roofing specialist, look for:
✔ Experience & reputation – Choose a roofer with a strong track record and positive customer reviews.
✔ Insurance & accreditation – Ensure they are fully insured and members of professional bodies such as the NFRC (National Federation of Roofing Contractors).
✔ Transparent pricing – Avoid companies that give vague estimates without a full roof inspection.
✔ Warranty on repairs – A reputable roofer will guarantee their work, giving you peace of mind.
