Subject: Roof falling to pieces-literally

My dad’s roof has a problem. He built the house in 1952, knows a lot about building-electrician for 50+ yrs. Of course he used the products/methods common then. Now, his 14 yr old asphalt shingles are in very bad condition in one area. He has a ranch w/ hip roof, 6/12 pitch. He knows better but he only bought the 20 yr asphalt shingles, traditional 3-in-1 type, brand? The original asphalt shingles from ’52 lasted 33 yrs. I want to know what caused the localized damage.

It’s on the south side, mainly ese of the chimney that is in the center of the house. My parents burn wood about 8 mths of the year to supplement their electric ba$eboard heat. That area would be downwind of the prominent winter wind (southern Michigan). Could residue/junk coming out of the chimney and landing on roof do this? Some of the shingles are falling apart. They have become very thin, some curled corners, especially next to eaves. Or, could the chimney heat up the neighboring area in attic and have condensation in that area which rises to the roof?

Or, the tv tower and antenna is immediately over this area. My dad (who also installed tv antenna for 50 yrs) thinks the rain is mixing w/ the alum, etc on antenna and the drips w/ chemical are doing the damage on this particular brand/quality of shingle.

Or, the attic could probably used a ridge vent-only has the (2) older triangle vents on each end (e & w) and I don’t know what he has for intake (soffit)-add if needed. I’ll look it over better and check out the attic thoroughly for condition/damage.

No history of ice dams or the snow melting pre-maturely from roof.

We plan to do a tearoff and install laminated asphalt, Pinnacle by Atlas? On the south side (about 13 sq) only this fall-kindof an emergency repair, and do the rest later on.

Any ideas about what caused damage? Know it is hard w/o seeing the roof.

Thanks. Appreciate any advice?

"It?s on the south side, mainly ese of the chimney that is in the center of the house."

Here in the northern hemispere of the world the first part of a roof to fail is the southern exposure. There is nothing more damaging then UV rays to a roof.

and of course,

"Or, the attic could probably used a ridge vent-only has the (2) older triangle vents on each end (e & w) and I don?t know what he has for intake (soffit)-add if needed. I?ll look it over better and check out the attic thoroughly for condition/damage."

inadequate ventalation is another common cause for premature failure.

20yr roofs hardly ever last 20yrs. Especially three-tab. It sounds like he bought the cheapest roof out there. Too bad he didn't fork out a few extra hundred back then. I always offer 30yr laminates as my base bid then usually for $400 to $800 more they can upgrade to a 40yr product. He should go through his warranty paper work and get a claim going on this roof. He should be entitled to 30% of the product cost for that material at the time of purchase. Some product reps will even give you the materials for free to redo the failing side. I hope you have your warranty paper work. It amazes me how many roofing companies don't give the manufacturer's warranty paper work with the installation of a roof. Or even a written workmanship warranty as far as that goes. If you didn't get it you are out of luck.

Hope this helps,
