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

context.

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.

“Why EPDM is better than Felt”.

hehe!! The Text associated with this link has now been removed. –

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.

Summary

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 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

vulnerable.

Conclusion

Felt Roofing Generally hits Rubber Roofing out of the Park.
