New roof, shallow pitch, on the cheap...

[HughF]

The background: I've lived here all of my 40yrs, my dad built it in '72 from demolition materials. Parents had an agricultural tenancy under the '87 act, without succession rights. They died last year.

 

I've been there for a year on an eviction notice, now have a new 3yr lease to allow me to stay and carry on tidying up the 10 acres of scrap that my dad accumulated, and I'm obliged to clear as executor. In the meantime, I need to re-roof the house, as the old roof leaks, and I'm responsible for repairs.

 

The requirement: Cheap, fast to fit, light weight, good for a shallow pitch

 

The options:

 

1. Box pan tin in ral7016, over battens, new felt.

2. Sark the roof with OSB, get torch on felt applied.

3. Go straight over the rafters with insulated box pan tin.

4. Sark the roof with OSB, apply grace 'ice and water shield' to the whole roof, apply felt shingles. I've used 'ice & water' before and it's amazing stuff.

 

What would you do? My concerns are that option 1 would be too noisy in the rain.

id just use box profile sheet, painting the whole thing in some kind of sealer sounds like a massive amount of work. sounds like it wont be your problem in 3 years. sometimes box sheeting and the insulated stuff is cheaper if you get a rubbish colour.

I've patched the cracked asbestos with sealer for now, and the water is no longer coming in... Box profile seems a sensible option, or even regular corrugated. I expect I'll have to run anything past the landlord to get their approval.

 

Ice and water shield is a self-bonding roofing felt underlay that's used in the US underneath felt shingles. Usually on the first few feet of roof, to prevent ice dams forming. It's like incredibly sticky, super wide, super flexible, flashband.
