Why You Need a Specialist Slate Roofer, Not Just a General Roofer
While many general builders and roofers are highly skilled, slate roof repairs are a specialist field. It’s not simply a case of climbing a ladder and swapping a tile. Slate is a natural material that requires a delicate touch and specific knowledge that only comes with experience. Using a tradesperson who isn’t a seasoned slate roofer can, unfortunately, lead to more harm than good, potentially causing further breakages and improper fixes that will fail in a short time.
The Unique Challenges of Slate Roof Repairs
A specialist slate roofer understands the nuances of the material and the traditional techniques required for a lasting repair. Slate is brittle and can easily be cracked or broken by someone who is inexperienced in walking on a slate roof or handling the material. They will know how to use a slate ripper and a slater’s hammer correctly to remove the broken slate without damaging its neighbours. Furthermore, they understand the importance of matching the new slates to your existing ones. Slates vary enormously in type (such as Welsh Penrhyn, Spanish, or Brazilian), size, thickness, and colour. A specialist will be able to identify your slate and source an appropriate match, ensuring the repair is not only watertight but also aesthetically seamless. They are also adept at working with the traditional fixing methods, such as copper nails and understanding the condition of the underlying battens and roofing felt, which are crucial components of the roof's overall integrity.
Common Signs You Need a Slate Roof Repair
Identifying a problem early is key to minimising damage and keeping repair costs down. Some issues are obvious, while others are more subtle. It’s wise to carry out a visual check of your roof from the ground, especially after a period of high winds or heavy rain. Here’s what to look out for, both inside and outside your property.
Telltale Signs Inside Your Home
The most common internal indicator of a roof problem is water damage. Look for damp patches or discolouration on ceilings, particularly on the top floor of your house. These might appear as brownish rings and can feel damp to the touch after rainfall. In your loft space, check for signs of daylight peeking through the roof, damp or rotting timbers, a musty smell, or mould growth on the underside of the roof or on items you have stored. These are clear signs that water is getting past your primary defence – the slates themselves.
Telltale Signs Outside Your Home
From the safety of the ground floor or a first-floor window, you can often spot external problems. The most obvious sign is missing or slipped slates. You may even find broken pieces of slate in your garden or on a patio after a storm. Look for slates that are sitting at an odd angle compared to others, or ones that have clearly visible cracks. Another area to inspect is your guttering. An accumulation of slate fragments or gritty sediment in the gutters is a strong indication that your slates are "delaminating" or deteriorating with age. Also, pay attention to the leadwork (flashing) around chimneys, skylights (Velux windows), and in the valleys of the roof. If the lead is peeling away, cracked, or has lifted, it creates a direct path for water to enter your home.
