fiberglass or lead ?


Bryera

Recommended Posts

Well new year my lead valley started to leek and water has started to come In so I cannot afford to pay someone or have time to do it myself so going through the insurance so I have sent my quotes off to them and they have picked the roofer that will do it in fiberglass and he is charging £1260 to do both valleys is that a good price and is there any down falls with having fiberglass instead of lead?

 

I would have preferred the lead myself but how reliable is fiberglass and how long will it last before it needs redoing? And why have the insurance favoured fiberglass?  

 

Thanks

Welcome...

 

I take it the valleys are huge then..??!! They will be saying fibreglass as its cheap, but unless I've missed something they are paying a lot for two valleys !

 

Roofer is £300 for a 2 guy team round here, 2 days all done to strip and re-lead a pair of valleys. Assuming 450mm lead you are talking £120 or so of lead on a pair of 5m valleys

 

So about half the price quoted O.o

You seem to have forgotten the scaffold 

also a company approved to carry out insurance work has overheads, you may get two roofers for £300 but who pays there pension, insurance, supplies the van, etc etc. 

 

We pay lads £150 a day but a two man team in a van is £625 +vat per day.

Would consider yourself lucky insurers are paying, usually considered a wear and tear item, so not covered.  We have had to replace a number of valleys at our own cost.

Glass fibre (Fibreglass is a trade name) if done correctly.  If done incorrectly it will be a disaster, but you will know that very early on.

 

It is fairly easy to work out what it costs.  Find the area costs i.e 3 layers of 450gm/m2, 2.7 kg of lay-up resin, 0.7 kg of flowcoat/top coat will costs about £11/m2.

Multiply it by 4, round it up, so £50/m2.

Then add on the VAT , so £60/m2, and any extra costs like scaffolding.

 

Make sure they do it when everything is bone dry, not a drop of moisture.  Should be a warm day as well, but preferably not sunny.

 

I did some on my parents house nearly 30 years ago, it is still there.

Chances are they will use preformed ones like these

Nice design that, and a reasonable price.

But this intrigued me:

" FILON’s V-Flow DF valley troughs and accessories are fully recyclable at end of life. "

 

Would like to know how they are doing it.  It has been a problem with normal GRP because of the low costs and flammability.

I did experiments in the early 90's, but was not worth the effort.  Things change though.

Quick answer would be that fibreglass is much cheaper 

Lead for my two valleys was £500 

Fibreglass would have been 

less than a hundred

sure it may not be as good as lead

But nearly all the major house builders use it

 

The quote seems ok to me

Couple of days work for two men 

If it doesn’t P down 

Also They will have to hire or erect there own scaffold Asvits not a job that can be done safely off ladders

Well I just ask if he would be removing the lead and he siad no we be doing it straight onto the lead so we do not have to strip the roof this dose not sound right to me I did have another for £500 to do both lead Valleys  in lead but sounded cheap to me but thinking of going with that now

Only difference really is the local caravan folk  have a liking for lead but fibreglass is worthless to them. Both will keep out the rain if done properly.

Exactly 

A nervous three weeks till I took the scaffold down

They have to strip the lead. Lead expands and contracts at different rates to fiberglass. It will fail.

 

I've put in three valley's which were 65 meters long in fiberglass on a large project on the edge of the Atlantic with crazy exposed winds. Massive saving to lead and a much better job. You can have the fiberglass extend up under the last few rows of tiles or slates. Original lead roof leaked although it was very old and the downpipes and leaves weren't cleaned I'd say. The problem I had was it was a bad winter when roof works were ongoing. Needed good dry weather to do the fiberglass so it wasn't done until early April. The surface you fix to (in our case marine ply on battens to a fall) had to be very dry. Delayed the programme a bit.
