The Reason Things Are Done This Way. VI

Roof damage

Here is one of the photos of an inspection I did 2 days ago.  As you can see this roof has a problem.  It also has 3 layers of shingles.  As if the snow in Ohio wasn't heavy enough, this homeowner decided he'd add the weight of several layers of asphalt shingles. 

The problem here is an old house, an old roof and too many shingles. Why is the number of roofing layers limited.  When a roof system is designed there is a weight limit that the roof can safely carry.  If your truck is a half ton, you don't load 3 tons of uh........ lead on it and hope for the best (prayer might be appropriate). The same goes for a roof, shingles are heavy. Add to the normal weight plus 6" of snow and the trusses holding the roof up begin to bow. 

Although, this damage was caused by our recent storm it also exposed some damage that wasn't at all the storms fault.

Excellent blog, Jack and Izzy!  It reminds me of years ago, when a house I had listed went into escrow.  It was determined that the roof wasn't water tight.  So the Seller hired a roofer to put on a 3rd roof (Izzy - That's "roof" not "woof").  All layers would be asphalt.  The Buyer was agreeable to the third roof. 

The Seller gets on a cruise ship to Mexico, and leaves the roofer behind to put on the roof.  After completion, the lender wants certification of the roof.  We can't find the roofer who put it on to get the certification in a timely manner, so another roofer is called to certify.  Imagine my horror when he calls me and tells me the new roof had been applied with 1/2" staples - not the necessary 3/4" staples, which are code. . . .AAAAAArrrgh!  Anyway, the Buyer didn't care, because they wanted to put on a second story over the garage.  I wasn't really comfortable with that, but the Buyer signed a disclaimer that they were aware of the problem, and we closed the deal!  Sure enough 6 months later, I drove by the house, the new addition was built over the garage, and an entirely new roof (after all other roofs had been romoved, and resheeted.  I call that interim roof, the roof that lasted only 6 months.

Sometimes you can be a real deal killer Jack. Really, I like this little series you've put together. Keep up the good work.

Myrl - A six month roof.  That has got to be some kind of record.  Oh yeah, Izzy thanks you.

Ian - Ian this was a bad roof.  After I got up there (top of a story and a half) I started to think about the stability of the rafters, and I worried about that until the shingles started giving way. Thanks.

I've run into this a few times on some of our property flips.  Naturally we're always trying to stick to a budget but I always say if the roof already has 3 layers when we buy it we should count on putting a new roof on.

Justin, this place, even though the top roof was just 5 years old, was screaming for a new roof.

Every time I come over here to your blog it seems all I read about are problems caused by storms and snow. You need to get out of there! Plus I come over here all nice and warm and start shivering just a few sentences into my reading. LOL

I once had a Seller call me every epithet he could think of because I told my Clients that there were multiple layers on the roof. Mr Seller "guaranteed" me that there wasn't. Of course, he was not a roofing contractor and could not make such a guarantee under State of California laws. My Buyer had two separate roofing contractors come out who said the same thing I did. Ultimately, my Client passed on the house, which warranted a follow-up call to me from Mr Seller. I just let him rant and rave so that he would feel better about himself, then I went to On The Border for some jalapenos and margaritas.

I've only found three layers a couple of times, but many of the multiple layers are screaming for a new roof after just a year because of our 11 months of sunshine and hot, dry Santa Ana winds.

I saw Mryl's comment. She must have had some of our San Diego roofers from South of the Border visiting her neighborhood -- LOL.

Jack.. Three layers of shingles??  Oh my.  I can't imagine the weight on the roof.  Here in Connecticut you can only have 2 layers.  Is three legal in Ohio?

RR - For 3 months the weather does things that keep the roofers and siders busy all year long.  Someday I'm selling all and going south.

Valerie - No. The problem is anyone can put a roof on (they think). When the guys tell their potential customers that they can save them money, they're looking for the line to sign on.

Jay - Of course, your right.  I use wrong logic, they use right logic.  When they start picking the crest off the livingroom floor, well ...... maybe they'll learn.  Nah, then it will be the builders fault.

Jack - you know I was being faseeeshuuus...  I think I have seen three layers about twice over the years.  I see second layers quite often, even the ones the seller tries to hide pretending you are looking at only one layer of spanking new roof...

I've had buyers ask me if three layers are "illegal."  I truly don't know about the "law" of man as regards three layers, but the "law" of nature will get you every time!

Jay - Yep I know.  We get three layers in some areas of the city on houses built in 50's and 60's.  You can tell how long they waited in between layers by the composition of the shingle.  The ones in the picture are mostly asphalt and that puts them in that range.  You can also tell by the weight.  Modern shingles are so much lighter and thinner that they make the green ones on the bottom seem like they're made out of lead.

Jack, I'm with Jay on this one. The more layers the better. The added benefit is you can have a spontaneous skylight after the first heavy snow.

I almost gave the one in the picture a skylight a little down and to the right of the hole from the wind.  Might leak a little, but caulk should take care of it.

Caulk is your best friend Jack. That is after Izzy.

Believe me, after I go through a roof they are going to need more than caulk.
