Enlisting an experienced commercial roofing contractor is essential for the technical nature of installing a mod bit roofing system. Common in the UK, these membranes are less sensitive to temperature than thermoplastic and provide good weather resistance. This gives specifiers confidence in the knowledge that they will have unambiguous information when deciding which of our systems is best for their new build or refurbishment project. The regulations focus on avoiding working at height when possible, using appropriate equipment to prevent falls, and reducing the consequences of falls through fall arrest systems.

Our high quality Bauder Total Roof System offers a range of membranes, each with their own attributes, that enable the specified solution to meet the needs of each project.Our torch-free detailing is integrated into all the Bauder bituminous waterproofing solutions, including Bauder hot melt, to give versatile safe installation techniques for all roof types, site conditions and the client’s budget. The number of coats should be appropriate to the waterproofing requirements and anticipated traffic, but will usually be two coats, a minimum 20mm thick over an isolating membrane of type 4A black sheathing felt to BS747. For large areas use the 120cm ( 47inch) wide roof fleece and cut it to the appropriate length depending on the situation. All products are manufactured on computer controlled tinting machines and matched to the bespoke designer colours for each brand or to the official colour standards for RAL Classic, British Standard and NCS colours. Just Flat Roofing will always give proper advice that will need to be followed for the guarantee to be valid in the event of an issue.

Today’s single-ply membranes are strong, flexible and durable and have a typical life span of about 20 years but are often known to last longer. The choice of materials for the different components will depend upon type of roof, whether cold deck, warm deck or inverted (see below). BTRS is a fully bonded system suitable for new build and refurbishment projects within warm and inverted roof constructions with a choice of insulations; also used as a system to overlay an existing roof that is thermally reliable and still meets current standards. Overcoating bituminous sheets can be problematic as many solvent based paints will damage the intact bitumen or will not have the same elasticity and result in mud cracking on the surface.Then apply a brush coat of Elastodeck above and through so that the coating comes into contact with the substrate. Modified Bitumen (mod bit) roofing is a flexible, robust material combining asphalt, polymerized rubber/plastic, and fiberglass. Compared to traditional fiber-based felts, these cutting-edge felts are less prone to rapid aging, brittleness, and damage caused by weathering. EPDM is also protected against root growth, as a result of which it is perfectly compatible with a green roof.

With a lifespan of up to 50 years, our Resitrix and Hertalan EPDM range of membranes offer sealing versatility for every challenge and, provided the decking is sound and the structure can carry the extra weight, they prove to be the perfect flat roofing ‘overlay’. RD-Elastodeck is an elastomeric coating designed to waterproof aging and/or leaking bituminous roofing. Plan the sequence of the roofing job to ensure the availability of the right materials at the right time. Extremely lightweight, tough, and elastic, EPDM is the right choice for you if you are worried about expansion and contraction, often an issue with larger flat roofs. PVC is resistant to roots, as a result of which it can also be used for green roofs in combination with a fibreglass reinforcement layer.Our products in practice: we are committed to reducing the impact our manufacturing has on the environment as well as how our products can support the environment through the reduction of energy usage, recycling and reusing. Cleaning by mechanical or power tools is advised when more detailed surface preparation needs to be done on objects within the roof, such as chimneys, access ladders and bolts that could be heavily rusted. It is especially used in situations where the old roofing is in bad shape and therefore needs to be removed.

Avoid carrying out waterproofing work in autumn, winter or spring when the weather conditions are sometimes too uncertain. Class 5E can be used for the top layer and is already provided with a surface protection in the form of mineral granules.

The BRE Green Guide to Specification gives our bituminous systems various generic ratings, depending on the type of deck construction and the support structure used. Felt Roofing (also known as roll roofing and Bitumen Flat Roofing) refers to the use of roofing felt to underlay other building materials, such as bitumen or asphalt, separating the roof covering from the deck, allowing water to run off and providing an extra layer of protection from damaging weather. While temporary repairs can prolong a roof’s lifespan to some extent, a complete re-covering is ultimately the most effective long-term solution. The sheathing felt should be laid loose with 50mm overlaps and will protect the mastic asphalt covering from damage caused by thermal movement of the deck. Do not remove existing roof coverings until weather conditions are confirmed and all materials are assembled and checked.
