In this case, it would be pointless to repair or replace the valley without also repairing the shingle or tile issues. Take a look at our article on repairing broken roof tiles to find out more about the costs associated with the job.
A full replacement of the valley or valley tiles will involve removing all the tiles, all the cement and also the under-felt (which is usually rotten anyway). If you have a bad water leak coming from a faulty roof valley, where water is staining the ceiling of the floor below, you need to replace your roof valley before serious damage is caused to the building structure. The Danelaw® product range includes both dry fix and traditional open valley troughs for a variety of tiles. All our valley troughs are made from glass-reinforced plastic (GRP), an excellent alternative to lead. Dry fix GRP valley troughs are mortar-free, providing hidden water gulleys at the roof valleys. Additional eaves closure pieces and counter battens are not required and they create a close-cut appearance. Further, the training centre is CITB approved and the tutors are experienced in leadwork and training applications. If your roof felt is damaged, repairing it is a fairly straightforward job – especially if the only roofing material is felt. However, if you have tiles on top of the roof felt then getting access to repair the felt will require removing the tiles and then replacing them once the felt has been successfully repaired.To mitigate the risk of staining, and provide an aesthetically pleasing surface finish, a coat of patination treatment should be applied to rolled lead sheet. Moreover, at The Lead lads, a further application of patination oil will also be applied at the end of each project. Importantly, gaps in the timber are acceptable but should not exceed certain parameters based upon the code of lead being used. Often, there is no way to tell whether there are any necessary repairs on your roof until somebody has had the chance to get up there to look.
Lead is the softest common metal and can usually be bossed without the applicantion of heat. However, if cold weather prevails. leadworkers often add heat using a small gas power blow torch to make the process of bossing easier. Be a Bossing Boss | The Lead Lads These roof valleys direct water to the guttering on your home without it discharging over the sides due to long upstands either side of the valet. They also have a variation available in which there is a central upstand for homes with two roof slopes that have uneven pitches. Another major issue which can cause roof valley leaks is thermal expansion. Prolonged hot weather can eventually cause roofing materials such as tiles and underlay to shrink and expand as the temperature changes, making them more vulnerable. This means that when storms or high winds come about, your roof is more likely to suffer damage and spring a leak. The best way to prevent this is to ensure that your roof has been installed correctly, with enough give to absorb movement. How to Fix a Leaking Roof Valley The main aim of either a warm roof or the provision of ventilation is to mitigate underside corrosion of the metal which may be caused as a result of condensation. Forming Ventilation Details | Lead Roofing Ventilation can be formed in a number of ways and should be continue under the substrate onto which the lead sheet covering is fixed.
To prevent condensation in roofs of heated buildings where the relative humidity may be expected to rise above 40%, it may be necessary to install additional insulation around roof outlet bodies. If you have a missing or loose tile that is letting in water, this is something you need to get fixed immediately. If you leave it to continue leaking, you will be repairing a whole lot more on the inside of the roof and even in your home. A polycarbonate / ABS blend which offers durability, high impact strength and long term resistance to ultraviolet light.
Perform a full inspection of your roof to determine what exactly is causing your leaking roof valley, and what needs replacing.
Leak repair cost
With any job where roof tiles are removed, you will find that some are damaged, or you will actually break them in the process or removing/refitting - so always have spare tiles to hand. Though most tiles are not expensive, so this is not a major problem in terms of cost. In the majority of cases, a complete roof valley construction is required, and cement is the best option. However, sometimes the roof valley itself is in good condition, but the cement is in poor condition and crumbling, or the roof gully is at fault, so it can in some circumstances be possible to just re-bed the tiles onto new cement, leaving the existing valley in place. 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.
Another big factor in the pricing of any job is the size or amount of work that is required. A semi-detached that requires only one valley will be considerably cheaper than a detached that needs 3 valleys, not just in the cost of materials, but in the manpower and time consumption. 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 However, if mild steel, galvanised steel or iron were to be used, there is a risk of corrosion occurring at interfaces exposed to weather.Breather or vapour permeable membranes are not suitable for use under leadwork.
