Felt Roofs & Felt Roofing in Plymouth
Here at Acorn Roofing Solutions (ARS) offer a variety of flat roofing products ranging from a single plywood roof covering to a three-layer mineral system, along with a wide range of insulation board products for flats roofs staring at 50mm thick all the way up to 200mm to provide the necessary insulation barrier you require.
Using a three-layer system is the most cost effective solution, however the single plywood method is usually preferred. With all our flat roofs depending on the roof design installed we do provide a written guarantee on completion of the works starting from a10-year guarantee leading up to a 20-year guarantee dependent on the installation design you have chosen and the use it is for.
- The first layer – a breathable layer of felt covering, tacked down
- The second layer – Torch on 2mm cap sheet felt covering
- The third layer – Torch on 4mm to 5mm mineral felt producing a high quality covering
Lead work and drip-beaded edges are used to complete all our flats roofs as required and necessary. If you decide you want to ensure a longer life for your flat roof then we can use thicker layers of felt and upgraded materials especially if you are requiring our 20-year guarantee. Another option and quite popular is to install a two layer felt system and cover over with a reflective solar paint to produce the third layer.

- Older systems give new modern systems a bad reputation
Felt roofing material is not a new product on the market, its been around for a long time and due to this has built up a bad reputation with many folks, that perception now is out of date thinking and I will explain why.
A lot of people still think in the dark ages associating a felt roof with the pour & roll old felt system. This system was a number of bitumen felts that were quite thin and were glued together with a hot bitumen liquid applied to each layer turn. The system was not overly strong and had minimum reinforcing internally, some actually contained natural hessian fibres that rot out easily. It would crack in the sun and as it got older drying out cracks again would appear. Because it was so thin It was named tar paper or felt paper. Life expectancy was approximately 10 years.
This system is applied as it pretty much says on the tin. It’s a torch on felt proven to be very reliable. It should not be confused or associated whatsoever with the much older pour & roll system. Due to modern technology be made in the bitumen market with SBS & APP providing an improved UV resistance from cracking and damage the felt system has come along in leaps and bounds.
Torch on felt is manufactured into a roll and is laid and applied to the new roof surface using a propane gas blowtorch to heat up and melt the back of the felt melting the bitumen so as it sticks to the new surface its being applied to. It is usually applied as a 3-layer system being a breathable underlay that is perforated, this is covered over with a 2mm cap sheet layer and a final mineral felt layer from 4mm to 5mm producing a high quality covering.
So as to keep the joining and the joints of the felt apart as far as possible from one another it is laid in a half lap method. The top final layer usually the thickest can be in a coloured mineral in red, green, grey, brown or purple and is called the cap sheet. As additional protective armour a reflective solar paint can be applied to produce an actual fourth layer if required. All layers are sandwiched containing weaved polyester material in the centre of the felt providing reinforcement and increased strength.
Its life span can vary due to its initial use but most roofing companies will provide you with a 10-year guarantee as in reality it will last 20 even possibly 30 years. Here at Acorn Roofing Solutions (ARS) do offer up to a 20-year guarantee dependent on the material used and the manner of use for the roof. So as you can see felt roofing has come a long way since yesteryear.
- It is the cheapest option by far
- It can be used for any size roof
- Due to current bitumen technologies it has proven to have versatile contraction and expansion properties
- Not particularly suitable to use as a balcony, especially during the summer months, it can be walk upon but no heels or step ladders should be used without some form of protection to the felt to prevent the risk of potential puncture of the felt
- During hot weather periods can soften the felt resulting in damage if used as a balcony or walkway with foot traffic without the use of promenade tiling to protect it
- Heating up and applying a patch piece of torch on felt can easily repair it when required. The easiest to repair is a solar finished roof with a plain felt
- Mineral felt is not unpleasant to look at and does come in a number of different colours. They do say that beauty is in the eye of the beholder
- Always ensure the installer has suitable public liability insurance regarding the hot works process required to fit this product
