Pitched Roof Windows

JJ Roofing Supplies offer the full extended range of Velux Roof Windows and Accessories as well as holding extensive stock. JJ Roofing Supplies is also the exclusive supplier of Duratech Roof Windows. Duratech Roof Windows have the same high standards of build quality of the industry leading Velux Roof Windows while giving better value for money and a larger glass area for the same size of aperture.

We supply the full range of roof window options, including both Centre Pivot and Top Hung (Means of Escape) opening windows, manual and electric operation, pine, white painted, UPVc and polyurethane frame finishes and clear or obscure (translucent) glass.

Flat Roof Windows and Skylights

If you have a flat roof over any room, from a garage or kitchen to a bedroom, bathroom or living room, a flat roof window can transform the space by allowing light and air to flood the space.

We match our range of pitched roof windows with a similarly large selection of windows and skylights for flat roofs, with insulated, fixed or opening upstands and single, double or triple skin polycarbonate domes.

Alongside these we also offer the new Velux Flat or Curved Glass Rooflights. A premium product from the market leaders, Velux, and the perfect option for homeowners with pitches between 0-15°. The units consist of a manual or electrically operated base unit which is then paired with a Curved or Flat Glass Cover.


Sold in the form of lead rolls, milled lead has been used on roofs for over a century and still remains a firm favourite with roofers today, even with the introduction of numerous lead substitutes on the market.

Here at JJ Roofing Supplies we work closely with ALM (Associated Lead Mills) to provide you with the full range of gauges and widths for lead rolls as well as lead slates and all the accessories and fixings you need to get the job done.

Pitched Roof Tiles

JJ Roofing Supplies can also supply everything you need to complete a beautiful and hard wearing roof. From the breathable membranes and insulation, roof tiles and roof slates, shingles, vents and ridge systems, we stock high quality products from the industry’s leading manufacturers like Redland, Marley Eternit, Cromar, Klober and Ubbink.

We also stock reclaimed tiles and fittings in a variety of types and styles so whether you need to repair or refurbish an older building with matching tiles or wish to give your dream home the mature finish it deserves, JJ Roofing Supplies is the one-stop shop you need.

Flat Roofing

For the best results with your flat roof project we stock GRP, torch on felt, EPDM, and promenade tiles and slabs from industry leading companies like Cromar, Icopal, ClassicBond, Cure-It and Castle Composites.

We also make sure that our stock and expertise with flat roofing is as extensive as it is with pitched roofs and we can supply everything you need to make sure your new flat roof will be keeping you dry for years to come.

Ventilation, Chimneys and Guttering

As well as the roof vents, tile vents and ventilated ridge systems that we can supply, we can also provide you with the chimneys, cowls and guttering that means you can order all the supplies you need from JJ Roofing Supplies and can rely on our quality, reliability and expertise to help you complete your roofing job.

Sun Tunnels

Also known as a Sunpipe, Suntube or Solar Pipe, these are a simple way of getting natural light into dim areas of your home by using a simple tube from roof to ceiling enabling the sunlight to brighten previously dark nooks and crannies.

Tools and Roofing Accessories

We have all the tools, products and accessories that will make your roofing job go smoothly.

Whether it be the battens or timber in general, ladders, hammers, nail guns, gutter brushes, torches, burners, buckets, chisels, snips, trowels, saws, spanners, gloves or boots, we have what you need online and, unlike our competitors, we stock most of our products.
