The most common reason for slipped slates is "nail sickness." This happens when the nails holding the slates in place—often made of iron in older properties—corrode over time and eventually break. Once the nail is gone, the slate slides down. Heavy winds and vibration from nearby traffic can also play a part. Our roofers in Ramsden can fix these by using new copper or stainless steel nails, or by using specialist slate hooks to secure them back in place.

Yes, we provide a specialist slate matching service. We understand that a patch of brand-new, mismatched slates can ruin the look of a traditional roof. We source reclaimed slates that match the age, colour, and texture of your current roof. If your roof uses modern man-made slates, we can usually find the exact make and model to make the repair invisible.

Spotting a leak early can save you a lot of money. Look for damp patches on the timber rafters in your loft, or light shining through the roof where a slate has slipped. On the outside, look for moss growth in specific areas, as this can indicate water is sitting there. If you are worried, we offer roof leak detection in Bromley using both physical inspections and drone technology to find the entry point before it causes serious damage.

Regular maintenance is the best way to avoid expensive emergency repairs. During a maintenance visit, we check the entire roof for broken or loose slates, inspect the lead flashing around chimneys and valleys, and clear out any debris from the gutters. We also check the condition of the mortar on ridge tiles. If we find small issues, we can often fix them on the spot, keeping your home watertight for the winter.

This depends on the condition of the majority of the slates and the nails. If you have a few slipped slates, a repair is usually the best and most cost-effective option. However, if slates are slipping constantly because all the nails have rusted away, it might be time for a re-roof. As experienced roofing contractors in Bromley, we will always give you an honest assessment. We won't suggest a full replacement if a simple repair will solve the problem.

The cost depends on how many slates need replacing and how easy it is to get to them. A few slates on a porch will cost less than repairs on a high, steep roof that requires specialist ladders or scaffolding.
