5 roof issues to check when buying or selling a property

Roofing London • October 19, 2022

Each year, thousands of home sales either pass or fall through due to issues identified with the roof. Roofs are one of the most important attributes for any property, so if you are looking to purchase or sell your property, Roofers London have put together some top factors to look for in your roof.


Assess the roof structure

Knowing whether the roof structure is safe or not can be difficult to determine from an external inspection, however there are a couple of tell tale signs you can spot from the ground level. If the roof appears to sag at any point, this can be an indication that the rafters or purlins supporting the roof have failed. If you notice this, then it is necessary to have further surveys carried out. In addition, if you notice cracking on the top of the external walls, or a wavy fascia line, this can be an indication of roof spread, which is where the rafters push out on the external wall causing structural problems.


Check the overall condition of the roof covering

If you notice any slipped or missing tiles, then this can cause a problem and may lead to leaks. In addition, if there is a significant amount of moss on the roof, or if there is ponding water on a flat roof, this can lead to future problems and could be an indication that the roof is ready for replacement. Other important areas to check are the ridge tiles at the top of the roof and the verge of the roof. It is common for mortar in these areas to become loose, eventually leading to leaks.


Gutters that are dirty, full of leaves and blocked with silt are a sign of poor maintenance and can put off any potential buyers.

Pay attention to dormers and chimneys

Dormer windows and chimneys are both common items that Roofers London attend to for the repair of leaks. As a home buyer, or seller, we advise to get these areas inspected. Whilst it may be difficult from the ground, you can use binoculars to check the condition from low level. Look for any evidence of the chimney stack, or chimney pots leaning at an angle. This can be a sign of structural issues that could be costly to repair. Also check the condition of the flashings around the chimney stack and dormer, as these are vital for keeping out water ingress. At Roofers London, we also advise to check the chimney pointing, as degradation of the chimney mortar is common and problematic.


Dormer windows are windows that protrude from the roof and these are prone to rot and deterioration, due to the increased exposure at high level. We advise that you check the condition of any wooden window frames for rot and check for any gaps between the window and the roof that could lead to water penetration.


Don’t overlook the gutters

Without proper maintenance, gutters can cause a real issue for damp and disrepair. Gutters that are dirty, full of leaves and blocked with silt are a sign of poor maintenance and can put off any potential buyers. In a worst-case scenario, damaged gutters can lead to ponding water around the property and damp penetration through the external wall. If you are a home buyer, it is important to check what material the gutters are made from, cast iron and timber gutters will need routine painting, so you should factor that in before purchasing the property. In some cases, the rainwater goods may contain asbestos, so if you wish to remove this, then you may require a specialist asbestos removal company.


Check the loft

We cannot stress the importance of looking in the loft when assessing a property for purchase; this is one area that property investors often overlook. If you can get safe access to the loft, then we recommend using this as an opportunity to look at following items: check the condition of timbers within the roof structure, assess the condition of any roof felt underlay, check to see if you can see evidence of daylight coming through the roof, as this is a potential for water to get in. Also use it as an opportunity to look for evidence of any damp patches, assess the condition and depth of loft insulation and look out for any nesting birds.

By Hightop Roofing London • December 28, 2024
Hightop Roofers London advise that as December settles over London, homeowners face unique challenges when it comes to maintaining their roofs. With frequent rain, occasional snow, and freezing temperatures, winter can put a roof to the ultimate test. By taking proactive measures, you can protect your home from leaks, enhance insulation, and prevent ice-related issues. Here are some essential tips to winter-proof your London roof and keep it in peak condition during the colder months. 1. Address Potential Leaks Before They Start London’s winter weather often brings prolonged periods of rain, making your roof’s integrity more important than ever. Here’s how to prevent leaks: Inspect for Damage: Examine your roof for missing or broken tiles, cracked shingles, or damaged flashing . These are common entry points for water. Clean Your Gutters: Blocked gutters can cause water to overflow and seep into your roof. Clear out any leaves and debris to ensure proper drainage. Check Around Skylights and Chimneys: These areas are particularly prone to leaks. Ensure seals and flashing are intact and watertight. Schedule a Professional Roof Inspection: A roofing expert can identify hidden vulnerabilities that could lead to leaks during heavy rains. 2. Enhance Your Roof’s Insulation Proper insulation is key to keeping your home warm and reducing energy bills during London’s chilly winters. It also prevents issues like ice dams. Here’s what to focus on: Inspect Your Attic Insulation: Make sure your attic is properly insulated to prevent heat from escaping through the roof. Seal Gaps and Drafts: Look for any gaps in your roof or attic where warm air might escape and seal them with caulking or weatherstripping. Consider Upgrading Insulation: If your insulation is outdated, invest in high-quality materials that provide better thermal performance. Ventilate Your Attic: Proper ventilation helps regulate temperature and prevents moisture buildup, which can lead to mold or structural damage. 3. Prevent Ice Dams and Snow Buildup While snow is less common in London compared to other parts of the UK, it’s not unheard of during December. When snow accumulates, it can lead to ice dams and other issues: Ensure Proper Drainage: Make sure your gutters and downspouts are clear so melted snow can drain away effectively. Remove Snow Safely: If snow does accumulate, use a roof rake to remove it safely. Avoid climbing onto the roof yourself. Install Heat Cables: For flat roofs or areas prone to ice buildup, consider installing heat cables to keep gutters and eaves clear. Improve Roof Pitch or Drainage: If ice dams are a recurring issue, consult a professional about improving your roof’s drainage design. 4. Conduct Regular Maintenance The best defense against winter weather is a well-maintained roof. Make it a habit to: Check After Storms: Inspect your roof after strong winds or heavy rain for any signs of damage. Replace Worn Materials: Swap out old or damaged tiles, shingles, or membranes before they fail. Trim Overhanging Branches: Trees near your home can shed branches or leaves onto your roof, increasing the risk of damage. Monitor Interior Ceilings: Keep an eye out for water stains or damp spots on your ceilings, as these could indicate a leak. 5. Work with a Trusted London Roofing Expert Winter roof maintenance can be dangerous and complicated, especially in London’s unpredictable weather. A professional roofing contractor has the tools and expertise to: Perform detailed inspections and repairs. Install insulation and ventilation systems . Safely clear snow and ice from your roof.
