APP membrane price

Kitovu price for a JUYONS APP torch-on roll

The price panel shows an APP membrane price per roll for one product, the APP Torch-On Waterproofing Membrane, Mineral Finish, held in stock in Zanzibar. What is confirmed for the rolls in stock: made by Hubei Juyons Waterproof Materials Technology, APP-modified bitumen, a grey mineral-granule top with a film-covered selvedge strip for the overlap, and a black PE film underneath. The maker lists it for laying with a torch.

The maker’s listing for its SBS and APP rolls gives 3 mm and 4 mm thicknesses, polyester reinforcement and rolls of 1 m × 10 m. Which thickness and roll size are in Kitovu’s stock is not yet confirmed, so ask before comparing it with another quote.

Listed bitumen membrane prices

One Tanzanian shop showed bitumen roll prices on its own pages on 12 November 2026. Kamaka sells them under its own brand as roofing felt and damp-proof course; its pages do not say whether the bitumen is APP- or SBS-modified, and do not give the roll size.

Rolls for a roof: a worked example

A roll of 1 m × 10 m holds 10 m² before overlaps. A flat roof of 8 × 10 m, 80 m², therefore needs more than eight such rolls once the laps along every edge and the upturns at parapets are added (our calculation: 80 ÷ 10 = 8, plus laps and upturns). Check the roll size of the product you buy before you count, since rolls are not all the same length.

The laps take their share too, and each maker sets its own. Sika’s Fidia P data sheet asks for 100 mm side laps and 150 mm end laps; with those, a 1 m × 10 m roll covers 0.9 × 9.85 = 8.865 m², and the 80 m² roof needs 10 rolls before upturns (our calculation: 80 ÷ 8.865 = 9.02, rounded up). Danosa’s 80 mm side and 100 mm head laps for its SBS roll leave 0.92 × 9.9 = 9.1 m² per roll, or 9 rolls for the same roof. The JUYONS listing gives no lap width for this APP roll, so ask for it with the price.

Under a torch-on sheet the deck is primed first. JUYONS gives 0.3 kg of primer per m², so the same 80 m² roof takes 24 kg of primer (our calculation: 80 × 0.3); prices for primer are on the bitumen primer price page. The roll itself is bonded with a gas burner: in Sika’s Fidia P sheet, the deck and the backing film are heated until the film starts to melt, and the sheet is then rolled forward onto it.

What changes the price of an APP membrane

• Thickness. In the table above, the 4 mm roll is dearer than both 3 mm rolls from the same shop.
• Top finish. A mineral-granule top is made to stay exposed on a roof, while Grupo Puma keeps its film-faced roll for layers under protection. The APP bitumen membrane page explains which finish goes where.
• Modifier. APP and SBS rolls behave differently in heat and cold; a quote that does not name the modifier is not a like-for-like APP membrane price in Tanzania.
• Roll size. A cheaper roll that holds fewer square metres can cost more per m².

How to order

Measure the roof or terrace, add the upturns at walls and parapets, and send the area on WhatsApp, naming the JUYONS APP roll. Ask for the thickness and roll size with the price. The full list of price pages is under prices in Tanzania.
