Identifying & Locating The Lead Roof Crack
The first step in any kind of roof repair is to identify the problem. Professionally installed lead roofs do allow for the natural movement caused by thermal expansion, but fatigue cracks or buckling can appear in lead roofs from continued expansion and contraction, usually over the course of 100 years or more. These cracks can quickly become big enough to allow water to ingress into the property, which can lead to further problems such as rot or structural damage to the roof rafters.
You should also keep an eye out for any corrosion of the lead which could indicate a lack of ventilation beneath the roof, and for a build-up of moss or algae which suggests an area of the roof that is subject to excessive moisture.
Do I Need Lead Roof Repairs Or Replacement?
Once you’ve identified the problem, you need to see whether it is repairable or if it is serious enough to require a roof replacement. Whilst most people may shudder at the thought of such a large job to put the problem right, a roof replacement (if necessary) will save a lot of money and headaches down the line when underlying issues would cause further and more significant damage.
Hopefully, if you catch the problem early enough, a repair should suffice. Small cracks may be able to be soldered shut, and it may be possible to weld a lead patch onto a cracked roof which is otherwise in good condition.
Patching the cracked lead with other materials such as flashing or felt is a temporary solution that will protect the roof whilst you arrange a more substantial repair. Beware of bitumen or similar paints as these are very short term solutions that can make the proper repair more difficult.
Seek Help From Lead Roof Specialists
Once you have identified the problem, the necessary method of repair and any planning permission required, you should get the help of a professional roofer who specialises in lead roofs. They will be able to strip the slates and re-lead them in a safe way. It is worth noting that not all roofers will be capable of this if they are not leadwork specialists, as this trade takes years to master. If you need help inspecting the roof and identifying the problem, to begin with, Silk Leadwork will be able to assist you with this too.
Hopefully, this has been helpful in informing you about what is involved in repairing a cracked lead roof. Remember to always turn to a professional if you have any doubts about the roof repairs you need to undertake, and one that specialises in leadwork if your problem is with a lead roof.
