To add to Bird's informative post here's a copy of a note sent to the dealer and mfr of our 1999 home:


We've been fighting water entry into our home off and on since purchase. The home is jointly owned by myself (**** *******) and ****** *****. The point of entry to the interior is the hall light fixture. The point of entry through the roof appears to be at some point above the vent stack for the bath fan. It only comes into the home when conditions are right and there is sufficient water entry that it can build up in the attic and travel to the light fixture.

After numerous calls, service calls and recent denial of warranty service, I have taken it upon myself with the assistance of ***** ****** of ****** and ***** Construction to investigate further. The first thing that becomes obvious (see pictures attached) is that the shingle staples are in the wrong place. Not just the exposed ones, but all of the staples appear to be below the tar strip. When the first warranty attempt at repair was performed (I believe by **** *****) there were several exposed staples that he gooped with tar. Obviously we did not care to have this, but figured that sealing them was about all a guy could do. In the area of the vent which seems to be where the water enters, the gaps and very tips of the shingle tabs were also gooped down with tar. Rather than lift the tab, the tar appears to be entirely on the exterior. This tar then cracked forming a small dam. This dam allows water under the lap, and since the staples are located so close to the lap, the water can then run down the leg of the staple or into the butt joint between shingles. The attached pictures are worth a thousand words.

At this point, we have lifted the tabs in the suspect area and sealed over the staples as well as up the butt joints and resealed the tabs from underneath. Mr. ****** ***** and myself have spoken on the telephone and has stated that he would have a roofing specialist stop by and investigate further.

We will await the findings of this investigation before further action is considered.

Ouch, that's tough. I'm afraid there are lots of folks in the roofing business who really don't know what they're doing.

I don't see any other "proper" fix other than pulling the whole thing off and redoing it. I'm also concerned about mold etc. This is a 1999 16x70 mobile home that we plan to sell soon when we build our house. We've never even wore shoes off of the entry rug. I think this may require the use of an attorney.

After this one is resolved I can move onto our first shop (1997 build stud wall with 2xgirts and steel siding) where the builders apparently forgot the headers then proceeded to install the 2x10s like the girts across the FACE of the studs. We had the steel off to apply housewrap (something they said I did not need) and styro between the girts to try and tighten it up. When told about this, the company (Dorchester) said it was fine, but I don't know of any code like this. They had a chance to save some serious labor (removing the steel) and passed which could come back to haunt them.

No pics of the "headers" but the building is the RH one. The one with 6x5 windows to the far side and 8x5 windows to the south...

Yeah I'm getting pissed at cut rate BS...

Just a comment on the use of staples on roofing shingles. I have shingled many roofs for over 40 years and I would NEVER, I repeat NEVER use staples on roof shingles. Unless you get everything exactly right (gun adjustment, air pressure, shingle quality, even shingle temperature) the staple in most cases will just blow thru the shingle and appear to hold, but even in a moderate wind you will lose some shingles. The correct way to install shingles in my opinion is with a large headed shingle nail either by hand or with a gun.
I would strip your existing shingles off and reshingle the entire roof to avoid more problems in the future.

Ken, I can tell you that a lot of the new homes built in this area have had stapled shingles for many years. And done properly, as I guess you said, they seem to hold up pretty well. But for me, personally, I'm with you, I want roofing nails.

I think we get some bogus 3 yr or maybe only 1 year warranty, BUT (correct me if I am wrong here) through the use of an attorney (if necessary) it should be possible to prove that the shingles were improperly installed and/or leverage the mfr to cover the entire re-roof as well as any water/insulation etc damages. Do I accept anything less?

Am I off base here?

As for nailing/stapling position, that should always be at or above the tar strip correct? I don't care for staples either, but I wonder if it has anything to do with the flimsy roof sheathing?

I'm not a sue happy person, but I paid 30k for this shack which at the time of purchase put us in quite a financial pinch. I bought locally (Marshfield) for supposed quality. I seldom buy cheap and use quality/reputation as my major factor when making a purchase.

Did I mention you can see light between the bedroom and shower at the wall to ceiling junction???

I found the following on one shingle co. website.

</font><font color="blue" class="small">( A minimum of four fasteners per shingle are used.
Correctly place and position fasteners below the sealant strip, but above the cut-out on three tab shingles, and in the nail line on laminated shingles.
The fasteners must be straight and flush with the surface of the shingle, not sunk into the shingle or sticking up at any point.
