Leaking Rooves on garden sheds.? I have 2 sheds within our garden; one is for garden tool...
I have 2 sheds within our garden; one is for garden tool storage the other I have made into an department housing my computer and Hi-Fi. Both roofs are covered in feel applied in strips bad a roll starting at the bottom edge so the superior ones overlap the lowers. Externally both appear to be intact but both leak surrounded by heavy precipitation. I've tried pinpointing the locations of the leaks from inside the sheds but despite applying sealer externally the leak occur most times it rain. I appreciate that I will have to apply unknown covers but would appreciate guidance as to which are the best and longest lasting materials to use. I'm a pensioner so I'd similar to to keep costs down but reliable percolate prevention is more important than adjectives cost to the bone. Incidentally both roofs are flat but fall roughly speaking about 30 cms from fund to front. What knowledge I own is about cars, motorcycles and planes; my ease of building maintenance is minimal. Any recommendation please??

Answers: your starter for 10 - its roofs.... not rooves.
Shed flat felt roofs are the nation biggest home roofing DIY project, having done roofing one-sidedly for 10 years (and as a family business for 35 years) and mostly these home spun repairs do not work, or if they do look awful or only closing for a couple months.
Ironically, getting a contractor in would predictable prove to be more expensive than replacing the whole shed... so not a really practical road to move about down.
Right... firstly, buy a really decent trait felt... (capping feel with a green mineral finish), you should spend no smaller number than lb20 for a single roll if you want a good clad felt, you can buy feel for less, but the level is ALWAYS questionable.
The felt itself - we own used Marley tough torch for about 9 years presently. It is an elastomeric bonded felt, which surrounded by lamens terms funds that you heat it up and stick it down, but the feel can breath and shift so not to cause blisters or splits.
Apply the feel directly to the old feltwork if its still solid, antiquated felt act as a great surface for new feel.
Apply atleast a 3'' overlap at joints (4''-6'' is better), and other make sure feltwork lead down the roof (in other words, as you say, the low feel goes underneath the higher).
Avoid tack the felt, use the torch on as intended for this you'll require a paw held bunsen or calor gas 'clickie'.
Thats about it really... if done correctly, modern felting can ultimate up to 30 years (with regular maintenance).
PS - All the above suggestions i would put in the 'home bodging' catagory.
Aquaseal - Cheap and gluey (good cheap alternative to flexacryl (lead sealant))
Bitumin on joints - last about 6 months since cracking and flaking.
Mike Hunts 'cheap felt' - not worth the money spend on it.
Cheap felt is exactly what it say... CHEAP... and tell me something cheap that last?
Look in B&Q or Homebase roof feel is very cheap
