What is a Lead Roof Valley and How It Helps Avoid Roof Leaks

A lead roof valley is a part of a roofing system composed of two pieces of lead tile or slate placed over the slope of a roof. The lead is then placed by a series of nails or screws. Roofers typically use this roofing system on a steep roof slope. It offers many benefits that affect the entire roof, and in this blog post, we will go through why it is important for your roof.

The Benefits of a Lead Roof Valley

Lead valleys must be professionally constructed to ensure that they will protect your building from leaks. It is a type of valley board or gutter found on many roofs. It is made from new lead, and it has several benefits that make it an ideal choice for many homes and businesses.

Here are just a few of the benefits of having a lead valley:

  1. A valley roof lining is highly durable. Lead is a very strong and durable metal so a lead valley will last many years with proper care and maintenance. Lead is also resistant to corrosion and weathering, so the valley tiles will look good for years to come. 
  2. Roof repair for a roof valley is low-maintenance. Because of its durability, a roof valley requires very little maintenance. You will not need to worry about repainting or sealing it as you would with other valleys, and it will not rust or corrode over time. 
  3. A lead roof valley lining is visually appealing. A valley lining has a clean, classic look with a roof where the roof slopes meet with a pitch that complements any home or business. It also comes in various colors to match your existing roofing materials. 
  4. A roof’s lead valley is environmentally friendly. Lead is a natural material that is 100% recyclable, so you can feel good knowing that your valley lining is helping to reduce waste and conserve resources when it is time to replace it.

The Best Time to Install a Lead Roof Valley Flashing

There are two different roof types – open and closed. The roof changes direction when there are two roof slopes. Open valleys are formed by nailing the lath to the decking, spreading lead sheets over the strip, then folding the lead up into the valley and securing it with cleats. 

Closed valleys are formed by nailing the lath to both sides of the valley and then installing prefabricated metal valleys flashing over the strip. Either valley can be installed anytime during new construction or a roofing project.

Two Main Tips for maintaining your lead roof valley

You can maintain your roof’s lead valley by taking some simple precautions. First, make sure that there is no debris or leaves in the valley. This can trap moisture and cause the lead to deteriorate. Second, check the valley, the strip, and the shingle for any cracks or damage. 

If you see any, repair them immediately to prevent water from seeping into the drainage and causing further damage. Secondly, a lead valley needs to be inspected by a professional every few years to ensure that the bed and everything are in good condition. 

Final Thought

A lead valley on roofs is a great investment for your home. Not only does it last longer than other types of valleys, but it also requires very little maintenance. You don’t have to worry about repointing the mortar or the GRP cracking or breaking, so you can rest assured that your roof will stay in good condition for years to come.
