What is the difference between 15 pound roofing felt and 30 pound felt?
Roof underlayment is the roofing material that lies between your roof decking and your shingles. Felt underlayment is the older of the two and comes in 15 lb and 30 lb rolls. The big difference between the two types of felt underlayment is that 30 lb is thicker, stronger, and less likely to tear than 15 lb.
Should I use 15 or 30 pound felt?
While #15 is a good option for most roofing jobs, #30 provides more protection and performance for steep roofs and flat roofs. This weight of felt is a good economic choice if you have a standard roof. But if your roof has a steep pitch, #30 is a better option because it is thicker and tears less during installation.
Can I put roofing felt on top of roofing felt?
It’s best to tear down to the bare roof deck so you can also check for any decking damage. But you can also add another layer of felt on top of existing. This will add additional thickness to the roof, so be sure that fasteners (nails) are long enough to penetrate both layers.

Can you lay roofing felt on top of roofing felt?
So the answer is no, you cannot. You should remove the old shingles and felt, and then carefully go over the roof deck removing every last nail or staple left over from the old roof. Then you make repairs to the roof deck; replace any rotted decking. Then you lay down new felt (it comes in long rolls).
What is roofing felt used for?
Roofing felt is most commonly used for the waterproofing of non-habitable garden buildings such as cabins or sheds.

How durable is a felt roof?

What is bituminous felt roofing?

Can you put felt on top of bitumen?
Once the bitumen is rolled back into position on top of the membrane, the two can begin to bond together. The same process is repeated across the entire surface of the roof. Note: If there is any old roofing material in place, in some cases torch-on felt can be applied directly on top.
