Roof update

Posted by: Fisbey on 14 February 2005

Got a quote on Saturday from a roofing contractor which was for a complete re-roof, chimney pointing, flashing, chimney pot (!) with a 25 year guarantee - the quote was actually cheaper than the warmroof, so it looks like the way to go....

He didn't recommend the foam spray either....

Nice one, good to read you have it sorted now.

One thing worth pointing out is - it's very doubtful that the guy who quoted you will actualy carry out the work personally, so if you are ok with heights and climbing scaffold, it would be wise to go up and check after they have felt and battened, just to make sure they have nailed the battens to every rafter, as some roofers will miss out nails if they're in a hurry, and you'll never know until years later when sections of slates/tiles will start to sagg down the roof....

I'm sure it'll be fine, but worth checking.

I have a quite a bit of flat roofing on my new house (asphalt) and I know they have limited lifespan - anyone good any ideas with what to do when it needs redoing?

Flat roofs do have quite a short lifespan, I know there are companies who will cover it with a fibreglass covering, but I couldn't vouch for it's longevity? Expansion and contraction being the main problem...

If it's covered well in the usual manner - 3 layers, hot bitumen/felt, hot bitumen/felt, hot bitumen/mineral felt and/or a final layer of gravel to protect it from the sun, it should last 10-15yrs, so long as the fall is sufficient so as not to pool water.

Can't really be more helpful than that, sorry not had much experience with flat roofs, other than avoiding them

Barnie,

It appears to be covered in the usual way as you suggest....not sure what you mean about the fall as it's flat? As in flat roof Confused

No flat roof is flat, it must have a fall towards the gutter. There is a formula for working out the minimum fall required, but I'd need to dig out my reference books to tell you exactly. It's calculated by measuring the overall length of fall/roof area

Barnie, it looks pretty flat to me so any fall is quite slight...water doesn't appear to pool on it though so I guess there must be a bit. Doh!

Perhaps I should have said - no flat roof is level Winker
