Roof Expansion Bubble

We are getting closer to owning an Eichler Home.

During the home inspection, the report notes a expansion bubble on the roof.

Is this easily corrected? How costly?

*** Further details ***

Roof Type is Tar with a reflective coating

Expansion Bubbles are caused by moisture entering between layers of the roof covering. This moisture vaporizes and expands, causing bubbles

You don't say what type of roof it is. Can you describe what an "expansion bubble" is a bit more? Since you are getting close to owning a home, check out the topic on this message board about what type of inspection to do.

We bought our Eichler last year. It had a 4 year old foam roof (done by a company that advertises on this site, name starts with A..)

We also found some expansion bubbles. Since the roof was still under warranty, and we could transfer the warranty from the previous owner, the fix did not cost us anything. The job was done in a few hours, so I do not think that it would have been too costly otherwise.

During this summer, I saw a few new bubbles popping up. I have yet to see where this goes...

I also have a foam roof that is fairly new so...so far so good. Perhaps someone else here can offer a suggestion of who would be a Tar and Gravel Roof inspector to find the source of the bubble and repair it. Get a quote now so you can negotiate a fix with the seller.

We had a new T&G roof put in less than a year ago, and we had a few number of expansion bubbles. Nothing to worry about according to the contractor. The bubbles are usually an effect of expanding air and moisture coming up from house in combination of the that the tar roll sheet (?) in spots isn't firmly attached to the roof planks.
If you have a lot of bubbles you can always ask a T&G roofer to see if there is any damage.

You may want to check with Wedge Roofing in Petaluma. They are a new advertiser on this site and I recently interviewed the owner, Ralph, for an article. They do many types of roofing, including T&G and have been working on Eichlers for 30+ years. Anyway, what I found most interesting was that they have an entire division just devoted to maintenance and repair issues. They will also repair roofs that were installed by someone else--something that is not too common these days. Anyway, their estimates are also free.
