DIY roofing


What's the best way for 1 man? Scaffolding?
I have a bungalow with a metal roof. I wonder would a 10x5x7 scaffolding work? I would attach the ladder to the scaffolding and the scaffolding to the house through the sofits.

1. take off old metal
2. remove old shingles
3. remove old decking.
4. Install typar
5. Install new decking
6. install durofoam, foil up
7. put back metal panels
8. new screws and washer
9. acrylic paint. green?

It's steeper than it looks -45'

#1, question is why are you thinking of doing this?
If It's to displace heat, adding a ridge and soffit vents and using a light color roof would do that. Also making sure the attic is air sealed and properly insulated.
#2, What's up with the scaffolding, a ladder with standoffs to get up onto the roof and another ladder with ladder hooks to climb up the roof is all you need.
A ladder should never be used on top of scaffolding.
#3, I'd never suggest anyone do this job with one person!.
#4, Metal roofing with exposed fasteners at some point is going to leak from expansion and contraction of the panels.

roof hooks are forboden here. Why do you think scaffolding is dangerous? Why would a ladder attached to scaffolding be dangerous?

Forgot one Joe.
#5 Why would you put Typar (house wrap) on a roof?

You can get vented foam closures to go under the ridge trim.

  • Synthetic Roof Underlayment
  • Stronger - 10 times stronger than 30# felt for the ultimate tear resistance
  • It will not blow off during installation and helps eliminate the need for costly roof repair.
  • Drier - the unique slip-resistant surface is waterproof to prevent moisture issues.
  • Lighter - up to 10 times lighter than 30# felt so it's easy to carry onto a roof.
  • Faster - the rolls are also 25 percent wider for quicker roof deck coverage.

Underlayment goes on top of the deck.

What kind of construction do you have? Vented or not?

If not, I would want to see more rigid board insulation to the exterior to get the R-38 for most regions and some above deck venting.

The other thing would be a harness. But it doesn't seem any safer to me.

Do you think i can scamper up the metal roof from the platform or will i need a ladder? Would you start in the middle or the edges? how much scaffold would i get? I supposing getting the metal panels back on will be the hardest part..

See the problem with an old house is you don't want damp air coming in though the sofits and hitting the roof beams. So if you can cover it with typar all the better, especially towards the ends of the roof where the ice builds up and moisture will come in to the house. Lots of houses use regular typar over the decking.

What happen was 15 years ago this roofing was installed wrong, and the old shingles were not removed and the rotten roof boards were it leaked.

Metal roofing does not even need an underlayment.
It's often done with just 1 X 4 purlins.
No way should ice be an issue on a metal roof except it sliding off the wood in one big swoop, so often time Ice spikes are added.
Without a ridge vent and soffit vent all the hot most air coming from inside the home is going to be trapped inside the attic, could not be more wrong about the moist outside air hitting the rafters, without proper venting, there's always going to be moist air up there.
Lots of houses may use Typar but not under metal roofing.
Since you seem to think metal roofing with exposed fasteners is the way to go I can see why you may need the added protection.
Seems like you have it all figured out and I've only been working on 100 plus year old houses for the past 40 plus years, so I'm done.
Hope it all works out for you.

There is a ridge vent but the old shingles are blocking it, so that is another reason to remove them. Yes i have the moor vents too.
So what can i do about the screws, the holes are already there? Well that's when the paints comes in.
