How To: Metal Over Old Rolled Tin

Return to Roofing over existing roof

The main part of this farm style house is 120+ years old, but additions have been made several times so the existing rolled tin roofing is not consistent. The roof has held up well over the years though I've always fought one leak. I want to consider a new roof over the existing tin, but am daunted by the seams and ribbing that rise up over the surface up to .75". What is the most direct manner to attack this for this do-it-yourselfer who won't be up to playing on the roof for too many more years?

Can you tell me what is beneath the existing metal? Solid deck or spaced sheathing? Can you email pictures to me of the existing? [email protected] Todd Miller

The main roof is spaced horizontal boards perpendicular to the direction of the tin. The porches and one addition on the back side of the house have a layer of plywood sheathing. Please ignore the cr port in front of the house, if I were more computer literate, I would have omitted it. Thank you for your expertise... Steve

I'm interested in the same question--I have an old metal roof--with spaced boards installation--it does not leak but is close to 100 years old--can I roof over this without taking old roof off

Linda, generally, I think that you'd be short changing yourself and your home by not going ahead with the tear-off. If you wish, email some pictures to me though and I will try to gove you some more specific help. [email protected] Todd Miller
