Recognising the Signs: When Does Your Roof Need Repointing?
Catching the problem early is key. A visual inspection of your roof from the ground floor, perhaps using binoculars, can often reveal the first signs of trouble. You don’t need to be an expert to spot the common symptoms of mortar failure. Here are the key things to look out for:
- Visible Gaps and Cracks:The most obvious sign is visible cracking or missing sections of mortar along the ridge line, hips, or in the joints of your chimney's brickwork. These are direct entry points for water.
- Crumbling Mortar and Debris:Look for sandy cement-like debris in your gutters or on the patio or garden path below your roofline. This is the decaying mortar being washed away by the rain.
- Loose or Uneven Tiles:If the ridge or hip tiles on your roof appear uneven, lifted, or are rocking in the wind, it's a clear indication that the mortar bed beneath has failed and is no longer holding them securely.
- Damp Patches in the Loft:On a dry day, take a torch and inspect your loft space. Pay close attention to the underside of the roof along the apex and around the chimney breast. Any dark stains, dampness, or a musty smell point towards a leak.
- Vegetation Growth:If you see moss, weeds, or small plants growing out of the mortar joints on your roof or chimney, it is an undeniable sign that the mortar is porous, retaining moisture, and actively decaying.
The Professional Roof Repointing Process Explained
A professional repointing job is a methodical process that requires skill, the correct materials, and a strong focus on safety. Understanding the steps involved will help you appreciate what your chosen tradesperson is doing and why cutting corners is not an option. A typical project follows these key stages:
- 1. Safe Access and Preparation:Safety is paramount. For most properties, this will involve erecting scaffolding to provide a stable, safe working platform. This is a significant part of the cost but is non-negotiable for ensuring the safety of the workers and your property.
- 2. Raking Out Old Mortar:The tradesperson will use specialist tools, like a plugging chisel or an angle grinder with a mortar raking blade, to carefully remove the old, decayed mortar from the joints to a depth of around 20-25mm. This must be done carefully to avoid damaging the surrounding tiles or bricks.
- 3. Cleaning and Dusting:Once the old mortar is removed, the joints are thoroughly brushed out to remove all loose debris and dust. This is a critical step as any remaining dust will prevent the new mortar from bonding properly. The joints may also be lightly dampened to reduce suction and ensure a stronger bond.
- 4. Mixing the Correct Mortar:This is where true expertise shows. A professional will assess the age and style of your home to determine the correct mortar mix. Older properties (typically pre-1930s) often require a softer, more breathable lime-based mortar to prevent damage to the historic brickwork. Using a hard, modern cement mortar on an older building can cause the brick faces to decay.
- 5. Applying the New Mortar (Pointing):The freshly mixed mortar is then applied. It is pressed firmly into the joints using a pointing trowel to ensure there are no air pockets. The tradesperson then shapes the mortar to create a neat, weatherproof finish.
- 6. Final Curing and Tidying:The new mortar needs time to cure and harden correctly. The tradesperson will tidy the site, ensuring all waste and debris are removed, leaving your property clean and your roof fully protected.
How Much Does Roof Repointing Cost in the UK?
The cost of repointing a roof is not a one-size-fits-all figure. It varies depending on several key factors, but a professional quote should always be transparent and itemised. Understanding these factors will help you to interpret the quotes you receive and budget accordingly.
Factors That Influence the Cost
The main variables that will determine the final price are the scale of the job and the ease of access. A small repair on a bungalow will be significantly cheaper than a full ridge repoint on a three-storey Victorian terraced house.
- Scope of Work:The total length of the area that needs repointing is the primary cost driver. Are you repointing the main ridge (typically 8-10 metres on a semi-detached house), the hip ridges, or a chimney stack?
- Access and Scaffolding:The cost of hiring and erecting scaffolding can account for a substantial portion of the overall budget, often ranging from £300 to over £800 depending on the size and height of the house.
- Condition of the Roof:If the tradesperson discovers broken tiles that need replacing or that the ridge tiles are so loose they require complete re-bedding (lifting and laying on a fresh bed of mortar), the labour and material costs will increase.
- Your Location:As with most trades, costs are typically higher in London and the South East compared to other parts of the UK due to differences in labour rates and overheads.
Estimated Costs for Roof Repointing
To give you a general idea, here are some ballpark figures. Remember, these are for guidance only, and you should always seek detailed written quotes for your specific project.
- Roofer's Day Rate:Expect to pay between £200 and £350 per day for a skilled roofer or bricklayer.
- Cost Per Metre:For repointing ridge or hip tiles, a typical rate is between£50 - £90 per linear metre, excluding scaffolding.
- Example Project 1: Ridge Repointing.To repoint the main ridge on a standard 2-storey semi-detached house, the total cost, including scaffolding, would likely be in the range of£600 - £1,200.
- Example Project 2: Chimney Repointing.To repoint an average-sized chimney stack that is reasonably accessible, you could expect to pay between£400 - £900, including access equipment.
How to Find and Hire the Right Repointing Specialist
Choosing the right tradesperson is the most important decision you will make. A high-quality repointing job will last for decades, whereas a poor one, often done by a "cowboy builder", can cause more harm than good by using the wrong materials or trapping moisture in your walls. Taking a measured approach to hiring will ensure you get value for money and a durable, professional finish.
Key Questions to Ask Your Potential Tradesperson
When you receive quotes, don't just look at the price. A good tradesperson will be happy to answer your questions and provide clear information. Being prepared with these questions demonstrates that you are a serious and informed customer.
- 1. Can you show me a portfolio of your previous repointing work, with examples of jobs similar to mine?
- 2. What type of mortar mix do you propose to use, and why is it the correct choice for a property of this age and type?
- 3. Is the cost of scaffolding, materials, and the removal of all waste and rubbish included in your written quote?
- 4. Do you hold public liability insurance? Could I please see a copy of your current policy?
- 5. What is the estimated start date and how long do you anticipate the work will take to complete?
- 6. Do you offer a guarantee on your workmanship and, if so, what does it cover and for how long?
- 7. Will you provide a formal written contract for the work? A professional may use a standard form, such as a JCT Homeowner Contract.
