Slate roofs are admired for their beauty, longevity, and ability to withstand the varied British weather. However, like any roofing material, they require proper care to ensure they remain in excellent condition over the years. For homeowners in Marlow, Buckinghamshire, maintaining your slate roof can help you avoid costly repairs and extend the life of your investment. At LS Roofing Marlow, we’ve created this practical guide to help you stay on top of essential maintenance tasks.
Understanding the Nature of Slate
Slate is a natural stone product known for its strength and durability. A well-installed slate roof can last 75 to 100 years or more, but its performance depends largely on the quality of the installation and the regularity of maintenance. While the slate tiles themselves are long-lasting, the nails, flashing, and underlayment can deteriorate with time.
Regular Inspections Are Key
Routine inspections are vital, especially after storms or heavy winds. You don’t need to climb onto your roof — a visual check from ground level or using binoculars can often reveal potential issues. Look for:
- Broken, missing, or slipped slates
- Rusting or lifting flashing
- Signs of moss or lichen growth
- Water stains or leaks inside your loft space
If you notice any of these signs, it’s best to call a professional roofer for a more detailed inspection.
Gutter and Drainage Maintenance
Water management is crucial for slate roofs. Blocked gutters can lead to water pooling at the eaves, which may damage both the roof edge and your property’s masonry. Ensure that gutters and downpipes are cleared at least twice a year — more often if your home is near trees.
Dealing with Moss and Algae
While slate is generally resistant to plant growth, moss and algae can sometimes take hold, particularly on shaded sections of the roof. These can retain moisture and, over time, affect the integrity of the tiles or encourage freeze-thaw damage in colder months. Cleaning should be done carefully — harsh pressure washing can dislodge or crack slates. At LS Roofing Marlow, we offer gentle, effective cleaning services to safely remove biological growth.
Flashing and Fixings
The metal flashing around chimneys, dormers, and valleys is one of the most common points of failure in older slate roofs. Similarly, the nails that hold slates in place (often referred to as “nail sickness” when they corrode) can fail, causing slates to slip or fall. Replacing flashing and renewing fixings are tasks that require professional attention to avoid further damage.
Replacing Slates: Matching Matters
If a slate does become cracked or falls out, it should be replaced quickly to prevent water ingress. Matching the replacement tile in size, thickness, and colour is important to maintain both the visual appeal and weatherproofing of the roof. LS Roofing Marlow sources quality slate to ensure a seamless repair.

While there are basic maintenance tasks that homeowners can do, most slate roof upkeep is best left to qualified professionals. Trying to walk on a slate roof without the proper experience can easily lead to damage or personal injury.
