opinions needed

---Case in point...We tore off a roof Monday and I took today off. My helper worked installing 30 lams today but was told by the customer first thing this morning that he wanted "storm nailing." That is, 6 nails per shingle. Well, that is news to me and was not in the contract nor was it ever mentioned. In fact, the customer mentioned how they lived in a sheltered area that was protected from high winds! ---Now we need another box of nails ($30) plus slowing my helper down costing me about $38/hour. Do I add that $$$ to the final bill??? I consider it a work change order not covered in the contract. ---What say ye??? Lanny

I would say,You are the one guaranteeing the work,and contracting to do the work,according to the standard of the craft,for a walkable roof,4 nails per 3 tab,and 5 per dimensional are pretty standard practice,Extra nailing would be required in a high wind area only(Apparently you discussed the subject of wind with the homeowner for that very reason).As it was determined by the homeowner that you weren`t in a problem wind area,and you felt your work would be secure with 4 nails (3-tab).This to me means you were doing as promised to the standard of the craft,and the extra costs for "additional work" performed for the customer would technically be considered worthy of a "change order,especially if your men had to go back ,and add nails to meet the new criteria,which was determined to not be necessary in order to meet the standard of the craft--yes,you should at the least charge for extra nails,time spent traveling to procure them,and a slight amount towards the extra labor involved ,installing the 2 "extra nails" that were not necessary.

Of course by standard,all scaffold pitch roofs should be getting 6 nails per shingle regardless,and if you`re nailgunning dimensionals it`s only one extra nail,and I would only charge for the extra nails if you were cutting it that close-probably charge about 2$ per square extra using laminates in that situation--both Tamko Heritage,and GAF Timberline require 5 nails per shingle,not 4.

I personally feel that 5 nails is plenty on laminates even in high wind areas,if the nails are in the right places,and adding a sixth nail,just makes you wonder where to put it,As it`s not cut,and dry as placement would be with a 3-tab shingle
