Double paper

Yep that is why I make the statement I'm sitting on the fence of this once great industry .>>>

BTW, it's fine to lap slate. :cheer:>>>

It's interesting, isn't it Ciak? :laugh:>>>

Building code here will not allow shingles to be overlaid on the end laps . No how no way. The code enforcement will make you cut them flush or t/o . The times they are a changing. Now gather round roofers the new codes are beyond your command Your old road is Rapidly agin'.Please get out of the new one If you can't lend your hand For the times they are a-changin'. The line it is drawn The curse it is cast The slow one now Will later be fast As the present now Will later be past The order is Rapidly fadin'.And the first one now Will later be last For the times they are a-changin'. >>>

I finished the roof the day before Hurricane Isabelle hit. Winds only hit 80mph or so. Did another near the beach. 3/12 pitch. No damage to it either. 6-7 nails per shingle.>>>

Go to 'Albert's Roofing, about the 6th one down for a glimpse.

I only went over 'single' layers of the dimensional shingles. Totally random which way the laps faced.

Learned fast that the ends of a shingle had to stay un-nailed until the it was decided which way the adjoining shingle was going to be laid.>>>

It think Frank laps the side lap of the shingles instead of butting together. I'm just guessing. Or it could be code for roofing naked :woohoo:>>>

Whoa. frank the scribes of old would be skinned alive if the were to use the " KINGS " name cepting for extreme reverence. Forgive frank Majesty the King Webmaster Steve grovel I'm not worthy . frank is a good guy he must of lost his bearings . What is a Dutch lap with dimensional I'm with Jedd on this one .>>>

Ducth lap is a type of shingle it comes in different shapes but mostly square and diamond shape I forget the exact demensions.

The first time I saw it I could not believe it could hold water but it does. Not recommended for lower pitch roofs though.>>>

Frank what do you mean by "Dutch Lap".....never heard that term.>>>

"She said GAF would be comfortable with that, it may be a problem codewise but not for GAF. Then I ask why do you want two layers of paper, she says added protection. I say if you have seven layes down and wind driven rain gets in then it will still find the nail hole and leak no matter how many layers she says yeah but not if the shingles are sealed properly.....well then I says if the roof is sealed then the paper becomes redundant with regard to protection. She laughs and agrees and that's that."

I asked about DeckArmor under metal or slate. Their response was " If it tears, it might leak". WTf???? I'm telling you, for the record. All of them are concentrating on underlay, not roof products. I used to think it was solely because of installer issues. It used to be. Not anymore, but installer issues show up faster.>>>

I'm back to finish. I called Elk, Timberline, and GAF before I did my roof. They ALL said the Dutch-lap was the way to go, AND unoffically, they all said they wished everybody would do it.

It creates 7" headlap and though lapped shingles always looked funny to me, I've never in my career seen a failure due to lapping.

My roof has sold many other lapped roofs becasue of it's unique look. It looks dimensional! :cheer:>>>

It's why I dutch-lapped my entire roof. 50 year Elks, with anything from 1/2" to 4" lap.>>>

"Change has come! It's why we have water absorbent shingles and only the paper-thin felt to keep the water out."

Jed, like it or not, the day of the shingle protecting the house is almost over. I've pulled off many a roof that had asphalt shingles over planks or plywood. There was NEVER any damage.

Lately, I've pulled off perfectly nice looking, undamaged, intact shingles 4-9 years old. The felt and decks were wet and leaking. NOT from condensation either.>>>

Well the long and short of it is ...........Manufacturer's warranty , Southern building code Insurance company want to mitigate damages before a storm with as much protection as possible. It is a good idea um mm should I go on? I know it upset you when caught in a situation after the fact. With out pain and failure we would learn nothing. There really is a right and wrong . It is not situational ethics .>>>
