About this deal

When undertaking lead work, especially when forming details, it is not always possible to use a wood roll to form a mechanical joint. The edge of a pitched roof as it meets the gable end is called a verge. Tiles here are normally fixed in some way to prevent wind and rain from getting underneath the tiles. Often the end tile of each row is mortared into place as shown below. Dry fix options for verges are also available from a number of manufacturers. Mortared Roof Verge Dry verge and ridge system on roof Lead Flashing The two most common types of gully/gully trap available are the P Trap Gully and the Bottle Gully. In general, they both do the same job, but there are a few important differences that need to be discussed. P Trap Gully This article aims to provide the ultimate guide to leadwork when used for roofing. We will explore the material, its uses, the application of lead and compare this to examples of our work over time.

If your valley flashing is made from lead, this should only be removed and replaced by a qualified professional. This is due to the toxicity of lead, and the experience needed to install lead flashing correctly.

The following description outlines the nature of the substrate and the specific leadwork underlays to be used for the same. The term continuous, means that ventilation should have an inlet, usually at the eaves, and an outlet, usually towards the ridge or apex. Our rainwater outlets provide essential drainage for flat roofs, which could otherwise suffer from water pooling or damp ingress. Flat roof drains are inexpensive to install and provide a huge benefit to your property. We have a variety of sizes in our range, so you can find the outlet that’s right for your project.

The quality of flat roof construction has improved enormously over the past couple of decades, which is both good and bad news. It means that your old (pre-1990s) flat roof is likely to be at risk. The good news is that you’ll end up replacing it with something far superior that should last you for the foreseeable lifetime of the house itself.However, it is important to ensure that amber used for forming lead details is appropriate. Usually, it is best to source treated timber sections.

At the end of the course, candidates are expected to be proficient in the theory and practice of working with rolled led sheet.The type of work required can alter the price also, with certain valley and roof types producing more of a challenge to work with than others, especially if there are multiple components that require replacing or repairing. Another typical requirement is to repair the roof valley gutter, which directs the water to the drain once it's off of your roof. BS EN 12056-3 uses localised rainfall data in l/s per m2 and takes into account the usage and design life of the building. The quantity and types of roof outlet to be used in a given application must be related to the roof area and expected volume of rainwater to be drained.

The world of drainage gullies can be a surprisingly complicated one. With a number of different gullies available for various uses, and a lot of inconsistencies regarding the use of terminology throughout the drainage industry, it’s easy to get a bit lost. But, given that they form an essential part of any property’s water management system, it’s important to know that you are using the right ones.Many properties built after 1970, however, are likely to have two separate systems; one to carry wastewater to the mains sewer and one to carry rainwater and surface water out to a watercourse. These systems are designed to put less pressure on the mains system by preventing “clean” water mixing with “dirty” water. In this type of system, you might find stormwater gullies and foul water gullies around your property, as rainwater and greywater will have to discharge into separate drains. Anything from an outside tap, washing machine, dishwater etc. is technically classed as foul water in the grand scheme of things, but effluent from these appliances is more commonly known as greywater. This relatively clean wastewater can discharge into a wastewater gully without any issue, but must not be allowed to flow into a rainwater/surface water drain. Also, for obvious reasons, you should never connect a gully near a toilet outlet, as that type of wastewater needs to stay within a sealed system. This section aims to outline some of the most commonly found details and compare them against real life edda plus as undertaken by The Lead Lads. This document provides recommendations for the design and construction of lead sheet roof coverings when applied to external surfaces. The guidance assumes that that materials will be fixed in accordance with conventional practice and traditional methods. Details Details Details…. Ventilation can be formed in a number of ways and should be continue under the substrate onto which the lead sheet covering is fixed.
