Introduction
Repointing a roof might seem like a straightforward job—scrape out some old mortar, apply new mix, and tidy it up. But the truth is, it’s far more complex than it looks. DIY repointing, especially on roofs, carries risks not just to your property’s condition, but also to your own safety. When done improperly, it can lead to leaks, instability, and expensive future repairs.
At Radcliffe on Trent Roofing Repairs, we’ve seen firsthand the problems that come from well-intentioned but poorly executed DIY repointing. In this blog, we’ll explain why roof repointing is best left to the professionals, and how getting it right the first time can save time, money, and headaches down the line.

What Is Roof Repointing?
Repointing involves replacing the mortar that holds ridge tiles, hip tiles, and verges in place. Over time, weathering and natural movement cause this mortar to crack or break down, leaving gaps that can let in water or loosen tiles.
When carried out professionally, repointing:
- Seals vulnerable areas from rain and wind
- Reinforces the structural security of tiles
- Extends the lifespan of your roof
- Prevents costly internal damage caused by water ingress
It’s an essential maintenance task—but only when done properly.
Why DIY Repointing Is Risky
From a distance, it may appear that a ladder, a trowel, and some mortar will do the trick. But there are several important reasons to avoid going down the DIY route.
1. Safety Risks at Height
Working on a pitched roof without proper scaffolding or safety equipment is incredibly dangerous. Falls are common and can lead to serious injury or worse. Even a short trip or slip could have dire consequences.
2. Technical Skill Required
Repointing isn’t just about filling in cracks. The mortar needs to be the right consistency, applied evenly, and finished properly to match existing work and ensure water doesn’t pool or seep in.
3. Using the Wrong Materials
Standard DIY mortar mixes often aren’t appropriate for roofing applications. The wrong type can shrink, crack, or fail under temperature changes—leading to premature failure and further damage.
4. Hidden Structural Issues
Professionals know what to look for beneath the surface. Loose tiles, rotten battens, or early signs of sagging might not be visible to the untrained eye. DIY repairs could cover up problems rather than solve them.
5. Poor Finish and Reduced Property Value
DIY pointing can look rough and uneven, which not only detracts from your home’s appearance but may also reduce its value. A professional finish ensures clean lines and consistent appearance.
Long-Term Value in Professional Repointing
While it may cost more up front, hiring experienced roofing professionals guarantees:
- Correct diagnosis of mortar deterioration
- Use of proper roofing mortar and tools
- Secure fixing of ridge and hip tiles
- Lasting protection against wind and water
- A neat, seamless finish that blends with the rest of the roof
A proper repointing job reduces the risk of future leaks and extends the life of your roof structure. It’s a preventative investment, not just a cosmetic touch-up.
