From many of the manufacturers, by doing a proper job using either an approved density poundage of a fibered aluminum coating or an approved elastomeric coating, the warranty length will be slightly extended on commercial applications.
Most residential applications are for a materials only warranty and pro-rated anyways, from original cost of materials.
I advise it to be done, but to usually wait about 30 days for any gasses to bleed out of the membrane after it has been installed.
To ensure a proper amount of the coating gets applied, it is best to put one coat on in one brushing direction and then a second application in the perpindicular direction.
All seams should be carefully inspected prior to covering them up with any coating though.
All coatings should be inspected and recoated as necessary about every 3 to 5 years. They do do a very good job if done correctly, in prolonging the life of the roof materials and also of keeping the iterior of the building cooler.
Pitch pockets are sparingly approved. A better flashing detail is done prcisely with the actual membrane and a target patch instead.
Plastic roof cement is against the manufacturers reecomendations and could void the warranty, but some approve of a MB Cement, which is a modified bitumen roofing cement.
Pitch pockets are good for only one thing. That is the first place I look for a source of water entry when doing a leak inspection. The plastic cement or even some pitch pocket fillers settle down to a lower level that the height of the perimeter of the sheet metal pitch pocket and hold water until it finally migrates its way in through the sealant. They all do eventually.
