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

I’ve Heard most of the Flat Roofers claims about various Flat Roof

coverings and I have to say that as a Flat Roofer the business is similar  

to the dieting business, in that 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 the decking via watering can’s etc and rolling and fitting the felt accordingly before the Bitumen Congealed. 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 its decline and in my opinion Torch on Felt with Bitumen Based Aluminium Paint is a superior product in many ways.

Felt roofing today although easier is still a more skilled job than Butyl or EPDM. The main reason that Butyl took off on N Ireland was 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 then and is still better now. The point is it needs to 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 and Z but mainly because EPDM is an economical Solution(Handier and Easier) than felt (Especially in the Winter months) but simply 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 stick a hatchet into it and it probably still won’t leak, whereas EPDM is some what more vulnerable.

Conclusion

Felt Roofing Done Properly hits rubber out of the Park.
