Slate Roof Repair Hayes, West London Answers | Roof Techies
If you are searching for slate roof repair in Hayes, the short answer is this: a slate repair replaces broken or slipped slates, renews the nails that fix them and checks the battens and flashings underneath. Most repairs are small and can be completed in a single visit. The rest of this page answers the questions people ask most often, in the order they usually come up.
What does slate roof repair involve?
Slate roof repair involves replacing cracked, slipped or missing slates and renewing the fixings that hold them in place. A roofer may also repair the battens beneath the slates, the underlay where it is damaged, and the lead flashings at chimneys, valleys and dormers. Each slate is held by two nails through its top edge, and the overlap between slates, called the lap, is what keeps water out. A proper repair restores all of these parts, not just the visible broken piece.
How can you tell a slate is broken or slipped?
A slipped slate sits lower or further out of line than the slates around it. A cracked slate has a visible split, often running from the nail hole. A missing slate leaves a gap where the felt and battens show. You can often see these from the ground with binoculars. Inside the house, damp patches on the top floor ceiling, staining on a chimney breast or daylight in the loft point to a failure somewhere in the covering.
Can one slate be replaced without redoing the roof?
Yes. A single broken slate can be replaced without re-roofing. The roofer lifts the slates above the damaged one, removes the broken slate, fits a matching replacement with new nails and re-lays the slates above. This is one of the most common small repairs, and it is usually completed within a single visit, subject to access and weather.
Which nails should be used on a slate roof?
Copper or stainless steel nails are the standard for slate. They resist corrosion, which is the most common reason slates slip. Plain steel or iron nails rust, weaken and let the slate move. If a quote does not state the nail type, ask before you agree the work.
How much does slate roof repair cost in Hayes?
The cost depends on the number of slates, the height and pitch of the roof, access, the condition of the battens and any flashing work. A single slate on an accessible roof costs far less than a repair across several areas of a steep roof. The most reliable way to compare prices is to request a free written quote that lists slates, fixings, flashings and clean-up separately.
Is slate repair better than replacing the roof?
Repair is usually better when the damage is limited to one or two areas, the battens are sound and the slates are stable. Replacement is usually better when the slates are delaminated across much of the roof, the battens are rotten or repairs are needed every year. A written assessment should explain which applies to your roof.
How long does a slate roof repair last?
A well-fitted repair with copper or stainless steel nails can last for many years, often as long as the surrounding roof. The repair lasts longer when the roof is checked twice a year, gutters are kept clear and moss is treated before it lifts the slates.

Does a slate repair need planning permission?
Usually not. Like-for-like repair of slates on a house does not normally need planning permission. Listed buildings and properties in conservation areas can have stricter rules about the materials and appearance of the roof, so check with your local council before changing the look of a visible roof. Building regulations do not usually apply to a simple slate repair.
Do I need to tell my insurer about slate damage?
If the damage came from a storm, fallen tree or other insured event, it is sensible to tell your insurer and keep dated photos and the roofer’s written report. Many policies cover storm damage to the roof, subject to the terms and an excess. Reporting promptly helps your claim and avoids disputes later.
What does a free slate inspection include?
A free inspection should cover the whole roof from ground level and, where access allows, from a ladder. It should identify the cause of any leak, record the slate type, check the nails and flashings, and note any moss, lifted edges or damaged battens. A good inspection ends with a written quote that lists the proposed work and gives a recommendation on repair or replacement.
Can painted or coated slate be repaired?
Painted or sealed slate can be repaired, but the coating can hide cracks and trap moisture underneath. A roofer should check whether the coating is hiding damage. Where it is, the coating may need removing before the repair so the slate can breathe and the new fixings can grip properly.
Why do slate roofs leak around the chimney?
The leak usually comes from the lead flashing or the mortar joint at the stack, rather than the slates themselves. Lead can crack or lift, and mortar can wash out over time. A slate repair should always include a check of these joints, because fixing a slate while leaving a failed flashing in place will not stop the leak.
How do I know if a slate needs replacing or just re-nailing?
If the slate is still whole and sits firmly once re-nailed, re-nailing is often enough. If the slate is cracked, delaminated or has lost its surface, it should be replaced. A roofer can tell the difference by checking the slate’s condition and the state of the nail holes.
