Seam sealed roofing quote


Recommended Posts

So I received a quote for a seam sealed roof today and whilst the material cost seemed super reasonable, the installation cost made me take a lie down. 
 

it’s not a complex roof.  2 valleys, 2 small hips and 3 roof light.

 

  • Approximate supply price per m²  for GreenCoat™ PLX £23-25 + VAT
  • Approximate supply price per m² for elZinc slate grey/graphite grey Zinc™  £35-38 + VAT
  • Approximate installation price per m² £120-180 + VAT

120-180/m2 install cost?

 

that only includes the breather membrane.

 

Thoughts?

Labour rates  are still very high 

Partly due to inflation Mostly due to the pandemic Most sites I work on are deserted by 330 pm

Quotes for one off jobs are still very high 

Shop around

It’s still a fairly specific product/ process the install cost will always be high. 
I used the green coat and really liked the product. 
have a ring around for installation. 

Can I ask what you paid/m2 for installation?

I can highly recommend https://themetalroofcompany.co.uk/ They tend not to sell direct, but will put you in touch with a local installer. I bought all mine from them but actually did the installation myself in the end due to the compexities of the install. However, they did put me in touch with a local one man band who priced the main roof without any penetrations and simply verge details at about £65/sqm with me supplying the scaffolding and doing some manual labour - this was at the height of Covid. However, once I decided wanted single welted verge detail to follow the curve of my roof and didn't want long flat panels along our deep eaves (due to total roof thickness), I ended up on my own.

 

Your price will be higher due to the complexities of detailing around your roof penetrations, hips and valleys, as they can impact the whole layout of your trays and their machined widths. So what might appear to be a simple roof might not be that simple for standing seam installation. I've attached examples from the Federation of Traditional Metal Roofing Contractors guide below.  This is part of my roof which was over 140sqm of steel in the end.

Did it myself. 

Hi Russell, I used the Tata Colourcoat Urban, self install. Paid about £25 - 30sqm in 2018 so that GreenCoat is a good price.

What was the installation process like?

Nicely done!  I'm very practical and would be open to that idea.  Did you have any valleys, hips or roof lights?

No i designed it all to be very square and simple. 
I new by keeping it simple I could do it myself and save a big amount. 
its large though with 355m of roof.
