Planning to reprint the Barth roof. I have a great pressure washer with several nozzles. Can I use it to clean my roof before I put the anvil on? Thought it might do a better job than a scrub brush.

Richard,
What is the psi of your pressure washer? Be careful where you use any pinpoint nozzle. You can actually dent or furrow the aluminum. You can also peel any dicor sealant either self leveling or no sag. You don't want to have to redo seals. Also be careful at any point of attachment. I used pressure washer but also scrubbed multiple times with an old heavy duty scrub brush on a broom handle with dawn dish soap and bleach from a bucket.

You don't want to be doing it again. Just be careful of high pressure washer.

I used a stiff scrub brush on a mop/broom type threaded handle. You can stand up and cover a good bit of ground.

I might have considered the pressure washer but would have been more concerned about creating or improving a path into the interior.(roof wasn't leaking) I saw where someone used a grinding wheel on their whole roof which was impressive however I decided not to work that hard. I felt like the old sealant that I couldn't get off by peeling off, scrubbing off or using a putty knife on would be ok to leave there, which was a lot(see link below). If its held for 25 years it'll hold for another 25 years.

Side note:
Rusty has ingrained in my head that there is a syndrome some of us suffer from called "If it ain't broke, fix it until it is", which I am slowly recovering from. That syndrome has gotten me into a lot of trouble over the years & ever since I heard that I have had to restrain myself & move on.

So back to roof: I cleaned spots, seams, covered with new sealer. See pics of the vent covers before & after on the "how I sealed my roof" post (this is where Kevin will insert link to that post

Kevin must be busy.

A good thread indeed, thanks Jim

Have Barths, will travel

I did mine on my hands and knees with pads of coarse,a stiff hand brush and Orvis soap.
My roof was so bad it had lichen growing on it. Came out nice and clean. Then re-seald as needed seams and rivits then the Anvil,4 coats.
