When it’s been expertly fitted and well looked after, a lead roof can be a brilliant weather-proof barrier that can last over 100 years.

Thanks to its flexibility and durability, lead sheet is one of the most popular materials for flashing and roof work in Britain, and it’s been that way for a long time. Many period buildings feature original, lead roofs that are still perfectly intact.

If your property has a lead roof and you’re wondering how to keep it looking its best, you’re in the right place. Our lead roofing experts are going to share some knowledge.

Maintenance Tips for Lead Roofs

Well, first off, you should know that lead is a hardy material. If your lead roof has been properly fitted and specified, it shouldn't actually need any maintenance.

That being said, it’s a good idea to keep your eye on it. Inspect it once a year, especially if you have had any bad weather, or you have heard things banging/scraping on the roof. Look for any problem areas or signs of concern…

What’s normal for a lead roof?

If you’re looking for problem areas you need to know what is normal for a lead roof.

Well, a fresh lead roof will have a matte, dark grey finish. However, over time the rain will corrode the top layer of the lead and that will cause a lead carbonate to form on the surface of your roof. This lead carbonate creates a unique pattern, but this is perfectly normal. This lead carbonate is protecting the layer of lead that’s underneath.

So, if you get up there and think ‘This looks old’ that’s probably the lead carbonate doing its job!

What’s not normal for a lead roof?

There are two main causes for concern when it comes to lead roofs:

• Bubbling: If your lead roof looks like it’s rippling away from the surface, or it’s bubbling, this could suggest it’s come away from the roof. In this case, it’ll need reattaching by professional lead roofing experts.
• Powder: If there is powder falling out this could suggest excessive corrosion is taking place underneath the lead sheet. This is not a good sign!

If you opt for a flat roof anywhere on your property, remember that it comes with a need for proper maintenance. Low-slope roofing London-wide should be checked every six months or so, or after spells of bad weather, to spot any signs of damage. No matter how small, these should be addressed before they escalate. Remove any debris (leaves, twigs and so on) regularly to avoid these blocking the gutters and allowing water to pool and stand on the roof.

If there are trees in the close vicinity, keep them cut back to reduce the amount of foliage that falls on your flat roof. And check internally for signs of moisture, dampness or water damage on a regular basis. Spotting problems early means resolving them will be cheaper in the long run.

Building a flat roof can be done in three ways. The simplest and most cost-effective choice for levelled roofing London-wide is to construct a warm roof where a roofing membrane is placed over the insulation that keeps the timber structure warm. Another option is to create a cold roof where insulation is positioned between the rafters under the ply roof covering. This is commonly applied to flat-roofed extensions.

The third method is the hybrid roof that contains diverse elements. Their designs require a gap of ventilation above a warm roof to prevent excess moisture within the roof structure.

If you’re looking for flat roofing local contractors, don’t just select the first firm you come across. Find a roofing company that’s been in business for a while and can demonstrate a good track record in installing, repairing, and replacing flat roofs specifically. Ask for recommendations from your own network or from a local trade association. If you need refurbishment work done to 50% or more of your roof, you’ll need a roofing contractor who can self-certify their work under the Competent Person Scheme. Otherwise, the Building Control department at your local authority will need to approve the job before it begins.

Ask whether they are covered by liability insurance and how long they’ll guarantee the work they will carry out. And never just opt for the cheapest quote unless you’re quite sure they’re the best company for the job. You can’t afford to compromise on your roof as the structural integrity of your property depends on it.

Ensuring your flat roof will comply with building regulations before installation can save property owners time, money and stress. First, the roof must have a slope of around 1:80, with water draining away to one or two roof edges. Waterproofing must be extended up to the adjacent walls with at least 150 mm from the surface of the roof.

Contractors must install ventilation in cold roofs. For warm roofs, the deck must be bonded with a VCL. The roof should have the capacity to withstand strong winds and be sturdy enough to take an individual’s weight. Finally, check whether planning permission is needed. Typically, this is only required if you live in a conservation area or a listed building, or are making significant changes to an existing roof.
