Flat Roofers & Repairs
EPDM, Butyl or Felt?
Specialist Flat Roofers
As Specialist flat roofers we must highlight that Flat Roof Maintenance is even more crucial than Slate or Tile Roofing as it will dramatically increase the life of your roof for minimal cost.
Most people know Gutters should be Cleaned, Checked & and any Minor Repairs (Pointing Etc) made good etc.
But thinking ahead with Flat Roofing there are many ways your Flat Roof can be improved through predictive preventive maintenance, many products, bitumen based paints etc that may be added to your flat roof at all stages of its life which will protect, enhance and dramatically increase its life span, while preventing damage or water ingress.

Flat Roofers Claims
Most of the Flat Roofers claims about Flat Roof coverings are similar
to the dieting business, there’s always the next big thing
with lots of impressive claims until you look a bit closer and
it starts to get a little more complicated, there’s always big headlines
with little to back them up except selective comparisons often out of
Felt Flat Roofing
In the 70’s Felt Roofing consisted mainly of boiling bitumen in Boilers
before pouring it on decking via watering can’s etc while rolling and
fitting the felt accordingly before the Bitumen Cooled. This
was quite a major procedure especially in Northern Ireland and its
very changeable Weather. The introduction of Torch on Felts however
has reversed the decline of Felt Roofing and in my opinion Torch on
Felt with Bitumen Based Aluminium Paint is a superior product to
Butyl & EPDM in many ways.
Although Torch-on Felt Roofing is much easier than its predecessor it
is still a more skilled job than Butyl or EPDM.
The reason Butyl became Popular in N Ireland was mainly because the
NIHE began issuing grants on Butyl. Not because it was a better
product than Felt but because it was a single piece of rubber it
was harder to “make a mess” of it. IMO Felt was better back then and
is still better Today. But it must be done right.
A Typical claim.

Could it have been because of me? Or Butyl? Lots of people say also
that EPDM is also better than Butyl?. But IMO it’s the other way
around. You should also perhaps remember that Butyl is more
expensive than EPDM It is also important to remember that both Butyl
and EPDM come in sheets made to order. Some Flat Roofers “pretend”
not to or simply don’t know this and lead people to believe that EPDM
comes in liquid form only. I have tried the liquid form of EPDM and
found it is problematic with the Northern Ireland Climate and is prone
to blistering and cracking. If someone requests a rubber roofing sheet
installed on new decking and don’t specify which type I will generally
quote for EPDM simply because it is cheaper and more logical in
competitive tendering not because it is somehow better for Flat Roofs.
If people want Butyl they have to pay more.
Of course there are plenty of Flat Roofers claiming X, Y & Z.
But it would be fair to say EPDM is slightly Cheaper (Handier
and Easier) than felt (Especially in the Winter months) This
doesn’t make it a better product which its not. Generalising
and comparing EPDM with felt is misleading as (for a start)
EPDM is thinner(1mm – 1.5mm) and generally less
expensive than felt and is generally used as single layer. Felt
is normally multi layered and up to half an inch thick. So
you could in most cases stick a hatchet into it and it
probably still won’t leak, whereas EPDM is much more
Felt Roofing Generally hits Rubber Roofing out of the Park.
