Sadly time has shown me differently.
How to staple roofing felt.
If you can find a roof with staples here because of code it is easy to identify them because so many have worked up.
Use a construction stapler or a hammer.
If you are only tacking down the felt for while you roof the building then 3 8 tack hammer staples are more then enough.
Install new flashing metal flashing is often called drip edge along the bottom of the roof near your gutters.
The paper should then be nailed in or stapled every three to four inches across.
Adjust the felt as you roll it making sure that it s straight with no bubbling.
How to do it.
All nails and staples should be placed on the lower half of the paper.
Apply and attach drip edge.
Valley ridges and hips should have a 6 inch overlap of paper.
Using your staple gun secure the felt to the roof.
Cut drip edge flashing at an angle at the corner press it lightly against the eave end.
Its way better to work with and will last longer.
Unroll your felt and secure it to your roof with a staple every 8 inches.
Begin by using your staple gun to staple down the first part of your felt to the corner of your roof.
Put fasteners at least every 8 inches.
Place the replacement felt over the exposed area of the roof and secure using the arrow htx50 professional hammer tacker and 1 2 t50 staples.
Start by stapling a row in the middle of the new roofing felt section.
Roll out about 10 feet of felt and fasten with staples or roofing nails with plastic washer heads.
Never install the felt vertically across your roof.
The tiny diameter of staple legs mean less hold with time.
I was on a shake roof and could see staples worked up over an inch.
Overlap each row at least 3 to 4 inches.
Since you are new to the game i would greatly recommend you use 30 felt over 15.
Starting at the bottom of your roof unroll a few feet of felt lengthwise.
Overlap and cut drip edges.
The staples held better than the nails.
If you live in an area with inclement weather you should consider using a special ice and water protector.
Where a roll ends and a new one is begun the two rolls should be overlapped by four inches.
