Services
Mastic Asphalt
When a smooth water proof coating is required, Mastic Asphalt fits the bill.
Applied in liquid form, Mastic Asphalt will spread evenly and seamlessly across surfaces and around pipes and other protuberances providing a waterproof roofing surface with no weak points or joins. Once cool, Mastic Asphalt provides a tough working surface, making it ideal for paving and walkways.
Mastic Asphalt is generally recognised as the premier waterproofing product available at this time. Its unique properties make it ideal not only for roofing but also for flooring and paving.
Single Ply Roofing
When you need a waterproof roof which looks as good as it performs, then Single Ply Roofing may be the answer. Strong and flexible, Single Ply Roofing membranes are ideal for flat roofs and also work well with curves and free form roofing shapes making them perfect in both commercial and domestic situations. Single Ply Roofing membranes are primarily made of synthetic polymer, reinforced with glass fibre or polyester as required. The membranes vary between 1.2mm and 2mm thick and are jointed using hot air welding.
Epdm Rubber Roofing
When you are looking for a long lasting dry solution for your flat roof then EPDM Rubber may be the answer. Ideal for porch roofs, garages, carports, balconies; in fact in any domestic flat roof situation EPDM rubber is waterproof and flexible.
Ethylene Propylene Diene Monomer Rubber, more widely known as EPDM rubber, is a synthetic rubber solution which is not just used for roofs. It is utilised in a variety of products from car door, bonnet, or boot seals to electrical insulation; in fact EPDM is used across industry in applications where water resistance is required.
Built Up Felt Roofing
When looking for protection for your flat roof, Built up Felt Roofing may well be the tried and tested method you turn to. Perhaps the most commonly used form of flat roofing in both domestic and commercial flat roofing projects, Built up Felt Roofing is as flexible as it is durable.
Built up Felt Roofing consists of successive layers of felt which are bonded using hot bitumen or heat activated on top of a decking layer. The felt used will vary in weight and thickness depending on situation and likely usage, leading to guarantees of 10, 15 and 20 years.
Structural Waterproofing
Kemperol 2K-PUR from the Kemper System is a highly flexible and durable waterproofing method, ideal for unique situations such as waterproofing wind turbines (you can see one of our case studies on a project waterproofing wind turbines here) and also very practical for live roofing and any structures that involve a lot of movement due to its elastic properties. This waterproofing method is also solvent-free and odourless, making it perfect for indoor projects such as those in schools, hospitals and food manufacturing plants.
Green Eco And Biodiverse Roofs
Rising rapidly in popularity, Green Roofs can add a special dimension to your building. Whether you opt for a sedum roof or an exotic garden, the addition of greenery will enhance your environment as much as it gives pleasure.
Dependant on architect's specifications, all of the Flat Roof systems offered by Pellow Flat Roofing Limited can be incorporated within a Biodiverse Roof design.
Green, Eco or Biodiverse roofs are ones in which the roof space has been covered with living plants. Subject to weight considerations these plants can vary from mosses to lawns and from plants and shrubs to a wildlife meadow.
Fibreglass
When a lightweight, strong and durable flat roofing system is required, Fibreglass steps up to the mark.
Making use of the same technology that enables yachts to skip lightly and dryly over the ocean waves, Fibreglass roofs have been growing in popularity in recent years. We are registered installers of Fibreglass roofing products supplied by the Matrix Composite Materials Company Ltd and can offer 10 and 20 year guarantees.
Fibreglass roofs are also sometimes known as GRP roofs, standing for Glass Reinforced Plastic.
Cold Applied Liquid Coatings
When you think of the advantages it is no wonder that cold applied liquid systems are proving increasingly popular for a range of Cornish new building and restoration projects.
Versatile and extremely flexible, the Liquid nature of these coatings means that they will form a seamless barrier on even the most complex of structures on private or commercial properties. Cold Applied Liquid Coatings are generally made of polyurethane/resin and when used on walkways and balcony areas include a skid-inhibitor for added safety.
Roof Repairs And Maintenance
When your flat roof starts to leak you need a swift repair to prevent collateral damage occurring. As Flat Roofing specialists, Pellow Flat Roofing provides an emergency repair service for all flat roofs. From storm damage to wear and tear, if your flat roof needs repair just give us a call. Nothing lasts forever but flat roofs will last longer if you carry out regular maintenance. This could include safe clearing of moss and debris, survey and minor repairs. Planning your flat roof maintenance is as simple as a telephone call to us and could extend the life of your roof and help to prevent major damage occurring at a later stage.
Questions
How long does a flat roof last?
Lifespan varies by material: single-ply 25-40 years, fibreglass 20-30 years, felt roofing 10-20 years, and liquid systems 15-25 years with proper installation.
Is a flat roof suitable for Cornish weather?
Modern materials like fibreglass and EPDM are specifically designed to withstand coastal conditions, including salt air, heavy rain, and strong winds.
Do flat roofs leak more than pitched roofs?
Not when properly installed. Our systems use correct falls and high-spec detailing to eliminate leak risks through professional installation.
Can I walk on my flat roof?
Yes, with appropriate design. We can create non-slip finishes or strengthen decking for walk-on terraces and balconies during initial surveys.
Do I need planning permission for flat roof work?
Most replacements fall under Permitted Development, though we handle building control applications through our Competent Roofer accreditation.

Jul 25, 2022 Report
We really have to express our thanks to Kenny and the team for the first class work they have done. Everything was professional from the first visit to producing the estimate and then giving us a much needed new EPDM Roof. We thought the value for money was excellent and no radios! Our recommendation will certainly go to our friends.
