Alternatives to Sarnafil roof covering
Planning an extension and the planning officer has made a condition of the consent that we use Sarnafil for a flat roof in dark grey or equivalent.
Can anyone recommend an alternaitve product? I do like the look of Sarnafil but have been advised that it can be expensive, albeit no suggestions of alternaives where forthcoming from this source?
View related: Sarnafil Help (and warning)2011-10-25 11:16:27I have a Sarnafil single ply roof installed on my recently completed extension by a professional installer who was sub-contracted by my builder.
After the bad weather in December (and once the snow had thawed) I had noticed that in a couple of small places the edging piece which goes from the last 6 inches of the roof edge over onto the vertical was starting lift off the membrane underneath.
I tried to contact my builder who didn't respond (not that surprising) so contacted Sarnafil who told me a guarantee had been issued and that I should contact the sub (they gave me the details).
Contacted the sub to be told my builder had never paid them and has since gone out of business. I had paid the builder in full months before. The sub is withholding the guarantee and wants me to pay for 50% of the roof again. Sarnafil are largely standing by their installer. Whilst I sympathise with them, their contract was not with me and I have honoured mine with the builder. I can't afford to pay for products twice.
So, can the small edges that have lifted be stuck back down? Is it a glue that is used, it looks like the edge was not properly adhered in a couple of places but I have no idea if this is DIY achievable or would require an expert.
I would rather do it my self it I can.
Any help appreciated!...
Lead flashing alternatives .... and Flashband2011-10-25 01:55:08Lead flashing alternatives are all the rage at the moment and get a good press, but Flashband and similar have been around for many years but tend to get a bad press.
Looking at them they are all aluminium foil with a butyl/bitumen backing, but the current crop of lead alternatives cost at least three times as much as Flashband
Lots of pros see Flashband as a temporary thing or a last resort, and yet these new lead alternatives are typically used without question.
So can someone explain the actual difference between these lead alternatives and Flashband, and are they really 'better'?...
Installed velux, optional components required / alternatives2011-10-26 15:34:31Hi,
Just fitted 3 velux P10 GGL windows to my extension and also have the EDW flashing kits to fit. I notice the (useless) instructions show shopping baskets for what looks like insulation and other kits.
I plan on just fitting some 20mm celotex around the outside to replace the insulation kit, what about the other kits, i.e. BFX and BDX. Are these really required as they seem optional and are there any alternatives, thanks....
New Flat roof - Single Ply membrane or Zinc/lead2012-09-07 12:35:54We are planning a smallish flat roof extension, which has been drawn up with a warm deck flat roof (apparently we are no longer allowed cold deck flat roofs in Scotland?).
The original design had a single ply membrane covering (sarnafil or similar) and I had been thinking of used Zinc or lead instead.
However, someone (not a roofer!) has suggested that I would need to ventilate between the warm deck and zinc/lead. Is this correct?
The flat roof will abut a wall of the house on one side but also join to an existing pitched roof on another side and I was told that might be where it gets difficult, in terms of venting where the lead/zinc is dressed to the pitched slate roof?
Appreciate its difficult to comment with a drawing/photo, but is the priniciple of venting the lad/zinc correct?...
Covering asbestos garage roof2012-01-03 11:47:01I have a garage with a bad leaking roof, it's covered with corrugated cemete asbestos sheeting. I tried to get it replaced but as its part of a block of garages I was told ?1500 for removal of my roof but everyone else in the block would need to follow suit so isn't gonna happen! I'm left looking at alternatives thinking I need to cover what's already there. So I ask if anyone has any ideas? I've looked at Acrypol or Flexcryl as an option, or should I consider reroofing with corrugated sheets over the existing asbestos?...
Felt Roof Liquid Waterproof Covering2012-10-16 14:40:57Hi all,
Over the weekend I removed the gravel covering on a flat felt roof. The previous owners had obviously got lazy with there maintenance as I didn't even know there was a gravel covering and had assumed it was a green roof with the inch thick covering of moss over it
Now i have cleaned the roof i am looking to apply a liquid water proofer over the existing felt to seal it. I don't think there are any leaks but would feel better know its all nicely sealed up. Can anyone recommend a product which would be good.
Thanks in advance.
Roofing advice needed on house survey results2011-10-25 22:34:06Just had our house survey back and would like some advice on any action you think we should take on this section about roof coverings (I'm aware of surveyors tendency for scaremongering but still want to check opinions on this). Wording as follows:
'main roof covering is a pitched and hipped design with covering of clay tiles....Cement mortar pointing applied to the underside of covering is in poor condition....
There is no underlay. Consequently damp penetration will occur but underlay can be installed when the covering is renewed.
The roof covering needs an overhaul to ensure it doesn't leak including attention to defective tiles...'
Any suggestions/advice/quotes would be much appreciated.
Lead Flashing vs Alternatives2011-10-27 15:16:40I am looking at the next stage of my pitched roof extension. The roof will be having flat interlocking tiles so the join to the existing house is nice and simple.
The flashing I am going to be installing will be mostly hidden behind uPVC panelling with around 50mm exposed before folding out over the tiles.
Lead is more expensive than many of the alternatives such as 'Flash Band'.
With having a flat roof with no complex shapes for the flashing to mould to what advantages would going with the more expensive and harder to work Lead give me?...
Flat roof replacement advice2011-10-31 21:48:22I have a ground floor bay window with a flat roof. Approx area is 2.5 to 3m squared.
It is rectangular in shape with no surface obstructions and is bounded on two sides by walls.
It is, or was, covered with three sheets of lead sheeting. One's been nicked.
I need to repair the damage and am considering alternatives.
I've ruled out a direct replacement as it will only get pinched again.
I don't want felt as it's not durable enough (in my opinion, anyway).
I don't want to spend a fortune, but it is a very small area to cover.
So, any views on possible alternatives - glass-fibre, EPDM, any others?...
Alternatives to velux roof windows2011-10-26 12:15:09We are planning a kitchen extension early next year, which will have a flat roof but we will retain a small pitched roof over the existing, small kitchen.
Our plans show a couple of velux windows installed into the existing pitched roof but I was wondering if anyone had alternatives?
I am not overly concerned about being able to open the roofwindows, as will have plenty of openable windows elsewhere and had thought about a large single pane of fixed glass but was unsure how this could be fixed in place?...
Flat Roof - workshop2011-10-31 17:34:26I have a workshop at the bottom of the garden which was not in a good condition when i bought it, and has now got worse. It is about 10X7m and has a flat roof, which leaks in a feww places. I want to cheaply (max life say 5 years) waterproof the roof. What is best - removing the old stuff and then
a. covering with bitumen
b. covering with roofing felt
c. covering with an expensive sealant
d. combination of the above
All advice gratefully received!...
Sealing flat roof edge2011-11-19 00:28:28I have re-roof my flat porch roof by rolling graveled paper over the old covering. I extened the covering over the exiting gravel edge. The edges of the new covering are visible when viewed horizontally. Shoul these edges be throughly sealed to the drip edge joint?...
Roof covering thats gonna be tiled2012-08-07 22:46:01What is the best roof covering to be used in conjuction with promenade roof tiles on a small roof terrace? I dont fancy getting the asphalters in!...
Lead Flashing Alternatives2011-10-27 21:53:38Is there any alternative to fitting lead flashing? We have 3m x 3m utility room on the East face of the house. Flat roof has been replaced with a pitched concrete tiled one. Obviously I now need to to waterproof the join between the tiles and the main house wall. I know the best solution is lead but I would like to avoid this as a) its expensive b) Its very nickable c) Its not easy for an amateur DIYer like myself to do properly. I've watched Youtube videos and it looks a bit of a mare + if I mess any of it up it'll cost me a wedge.
I thought the cheapest solution was a cement fillet with water proofer mixed in. Is this a good idea? Will it last any length of time? I don't really want to bodge it for the time being but if the cement lasts a few years that'll do me. If you wouldn't recommend it are there any other alternatives to this or lead flashing that are easy to fit?
EPDM, GRP or Felt2011-10-27 09:13:43Hi Chaps
Sure you've been asked this a few times already but here goes anyway.
New flat roof and unsure of how to cover it. I don't fancy felt, simply because it don't have a reputation of being permanent. It feels like a cheap and cheerful way to roof?. Is EPDM or GRP much better?. The one thing about these options seem to be that I am forced into the hands of window company's, not roofing company's who mainly seem to offer conventional felt.
Also, whats Sarnafil?
Which honestly is best long term value for money.
I don't know if I'm allowed to ask but what is a reasonably guide price for 8x5 Mtrs, fitted.
Leak around skylight2011-11-02 17:27:39Hi,
I have a large building at the bottom of my garden which has been there from before I moved in and we've converted it into a gym/summer room.
The roof is pitched although the angle is very shallow - definitely no more than 20 degrees and has two skylights.
A damp patch inside developed around one of the skylights and so I patched where I thought the leak was on the roof but the damp just go worse.
My neigbour (who knows a bit more than I do) tells me that the covering on the roof is not the correct type - in fact it's some sort of underlay over which the roof covering should be applied.
I've decided to put a proper roof covering up. My question is will roofing felt be okay for this and also how do I seal around the skylights properly so that there are no leaks?
Thanks for any advice.
Covering Dorma@s2011-11-02 17:27:32Hi all,
I have two great big dorma's on my chalet bungalow, which need to
be covered within the next 12 months, as the existing felt tiles are
on there last legs.
I have looked at wood panaling and UPVC panaling but wondered what
would be the best option for covering the sides of dorma's for good
appearance, insulation and noise.
Any thoughts ?...
Fascia board plastic covering2011-11-01 11:39:12Hi Guys
Just installed some soffit and fascia boards which were given to me by a mate who had them left over from his extension some 2 years ago.
I am having real problems peeling of the protective covering plastic as it should have only been on for a few months.
I have tried using a decorating blade scraper but it still only comes off in tiny bits.
Any ideas re some soloution I can use white spirits etc ?
Patio covering2012-07-09 03:01:04Need some advice. I'm brainstorming how i can replace the patio canopy in the attached photo with a permanent wood structure. My problem is how do i tie it into the 2 roof lines? Or, i couple get the roof of the patio covering up just above the gutters so it drains into the gutters and not attach it to the house.
upvc covering Wood conservatory2013-06-30 00:07:16hi
I have an old conservatory that has a woodern upper part that meets the felt flat roof.
This woodern part sits above the glass windows and I am thinking of putting a upvc covering onto this woodern upper part.
Just wanted to know if I fit the upvc direct onto the wood (no air gap) is there going to be a condinsation problem as upvc would be touching the wood.
Should I try to make a stand off gap so air can curculate between the wood and the upvc sheet ?
This old conservatory was built in a odd shape and is difficult to keep waterproffed hence the reason for the upvc covering....
