How do I know if my roof pointing needs repairing?

Roof pointing is the layer of mortar that seals the joints between ridge tiles, coping stones, and other roof elements. It may look like a small detail, but it plays a huge role in keeping your roof watertight and secure. Over time, this mortar can crack, crumble, or wear away due to weathering and natural movement. When that happens, water can seep in and cause serious damage to the roof structure and even the interior of your home.

If you live in or around Louth, it’s important to keep an eye on your roof and know when to call for pointing repairs Louth. So, the big question is: How Do I Know If My Roof Pointing Needs Repairing?

Recognising the signs of failing pointing

The first thing to look for is visible deterioration. Cracks, gaps, or missing mortar between ridge or coping tiles are clear signs that the pointing is starting to fail. You might also notice that some tiles have become loose or shifted slightly — this usually happens because the mortar holding them in place has weakened.

Another clue is water ingress. Damp patches on ceilings or walls, particularly near the roofline, often mean that water is finding its way through damaged mortar joints. If you see moss, small plants, or debris building up between tiles, that can also indicate gaps in the pointing. Even finding small bits of mortar or grit in your gutters could be a sign that the roof’s mortar is crumbling away.

If you spot any of these symptoms, it’s worth arranging an inspection as soon as possible. A professional roofing company like Raven Roofing can carry out a detailed survey to assess the extent of any damage and recommend the right repair solution.

What causes pointing to deteriorate?

Even the best roof pointing won’t last forever. Years of exposure to rain, frost, and strong winds gradually wear away the mortar. In coastal areas such as Louth, salt in the air can accelerate this process.

Poor workmanship or weak mortar mixes from older repairs can also contribute to early deterioration. Over time, natural movement in the building — caused by temperature changes, settling, or vibration — can create small cracks that expand and let in moisture. Once water enters, freezing and thawing cycles make the damage worse.

For these reasons, regular roof inspections every few years are a smart investment. Early detection can make pointing repairs Louth far more straightforward and affordable than waiting until major problems occur.

Checking your roof safely

If you’re confident using a ladder, you can inspect your roof from ground level or a safe height. Look closely at ridge tiles, chimneys, and gable ends — the most exposed areas. Check for cracks, missing mortar, or signs of movement. Inside the loft, watch for damp patches, mould, or daylight shining through where it shouldn’t.

If you’re unsure or unable to access the roof safely, it’s best to call a professional. Local experts such as Raven Roofing & Repairs offer free quotations and can quickly identify whether your pointing needs attention.

What happens during pointing repairs?

If your pointing is worn or damaged, a roofer will start by removing the old, loose mortar to create a clean surface. The joints are then cleared of dust and debris before new mortar is carefully applied. This process — known as repointing — ensures the new material bonds properly and seals every gap.

The roofer will then tool and shape the fresh mortar to ensure water runs off rather than pooling, helping it last longer. Once set, the new pointing restores the integrity of your roof and protects your home from moisture damage.

Professional companies like Raven Roofing use high-quality materials matched to your property’s age and style. They’ll also check the rest of your roof while on site, often spotting small issues before they become expensive repairs.

When to schedule repairs

It’s always better to repair pointing at the first sign of damage rather than waiting for leaks to appear. Small cracks or missing sections can quickly worsen in bad weather, and once water gets beneath the tiles, you risk damp timber, mould, and structural damage.

In general, if your roof hasn’t been checked for several years, or if you’ve recently noticed signs of deterioration, now is the time to book an inspection. Acting early not only prevents costly damage but also extends the lifespan of your roof overall.
