Roof Type Constructions
Longstrip metal roof constructions have traditionally been categorised into various types:
Cold Roof
In which the principle thermal insulation is placed at or immediately above the ceiling, resulting in the roof covering and structural deck being substantially colder in winter than the interior of the building.
Warm Roof
In which the principle thermal insulation is placed immediately below the roof covering, resulting in the structural deck and ceiling being at a temperature close to that of the interior of the building.
(The design principles of cold and warm roofs with regard to condensation and condensation control is the main difference between the two types.)
Inverted Roofs
In which the principle thermal insulation is placed above the roof covering, resulting in the roof covering structural deck and ceiling being at a temperature close to that of the interior of the building.
Hybrid Roofs
Combining the features of two or more of the roof types described above. Examples include structural decks with high thermal insulating properties combined with additional insulation and existing roofs to which thermal insulation is added.

At HL Metals we provide many services to assist you with your project, e.g. pre-tender budget costs, product advice, roof build up advice, roofing substrate requirements, recommended roof systems as well as full and comprehensive survey reports for existing roof structures. We readily supply all the technical information you need and are happy to answer any questions you have to make sure the whole process runs smoothly. We can assist with general specification requirements and more specialised roof and wall structure specification. We oversee our roofing and cladding works from start to finish.
We have worked on an immense range of projects from small residential buildings to large commercial projects, whether it is work on a new building, or changes to an existing building you are interested in, please do not hesitate to contact us for impartial advice or any further information on the services we provide.
Please bear in mind that for the purposes of imparting information about the products and services we provide within the pages of our website we predominantly refer to ZINC roofing or cladding. This is primarily due to ZINC standing seam being the most popular product we receive enquiries on. However, bear in mind that we can also provide COPPER, STAINLESS STEEL and ALUMINIUM for roofing and cladding depending on your budget and location.
If you are interested in a zinc roof or wall cladding on your new build property, extension or existing roof you can expect the following from HL Metals:
We have over 30 years' experience in the design of roofing and cladding and specialise in the design for traditional metals i.e. ZINC, COPPER, STAINLESS STEEL, and ALUMINIUM. We have gained an excellent reputation within the industry for our knowledge, expertise and attention to detail.
We can provide a contractor designed package for roofing and cladding. We will assist the Architect in the full design of the zinc roofing to ensure compliance and provide standard drawing details or full working drawings based on the Architects initial design. We are also happy to 'overlay' the zinc roofing or cladding requirements to the original Architects drawings to assist the builder on the roofing build up.
We have fulfilled design requirements for a number of smaller projects from private residential buildings to churches, schools and larger commercial projects.
We are highly skilled and qualified in the use of Autocad and Revit Applications and Drawing Software and we also have the expertise of a fully qualified Structural Engineering Service on hand should structural calculations be required.
We have been involved in the design of a number of prestigious projects including:
We work very closely with the metal manufacturing technical teams and have built up an excellent working relationship with:
By combining the expertise of both design and installation skills we are confident that we can offer our customers an excellent combined package of quality and service. We can also provide technical information on products and can assist with budget costs at pre-tender stage. Contact us now to discuss your next project.
