Your nail hammering skills are superb
Thank you
Very informative. It will make my first time doing shingles on my garage a lot easier, thanks.
Thank you for taking your time and making this video was very helpful
Very informative. Thanks to your input.
Thanks for this. Going to be putting tar paper on a shed I built this afternoon and this helps greatly with technique.
excellent video. the way you lay that paper was so clear to understand. Thank you so much sir. thank you
So nice of you
Great to the point video, good job! Thank you.
You're welcome!
looks great
Great video...thank you.
Glad you liked it!
My buddy taught me the exact same way as you teach. We just did my house took 8 rolls. I'm tired
Thank you
Thank you
I learn something new today
good deal
Muy bueno
👍
Great vid...so the wind lifted a part of my flat roof and I wondering if I could just tar or glue the roof down somehow. Any advice would help thanks
Possibly yes. Probably want to avoid sticking right to the wood. Here is a video of some modified cap sheet repair - czcams.com/video/Ko0kk1IKEPs/video.html
Thanks for the video. I am putting some of this on the shed today. I would preferred to cover it with white elastomeric. Is that a good idea?
I wouldn't. Covering with cap sheet would be better. czcams.com/video/TIVMQyUQlDg/video.html This video is self adhered cap sheet on a flat roof. If you use on slope, just make sure to back nail.
Is there a maximum time frame that felt can be on the roof before shingling? I need to do some deck repair and also remove 3 layers of shingles before winter hits. Will felt make it through a Nebraska winter until spring if nailed down properly? I'm wanting to purchase my shingles after tax season (Feb) then install them like I said in the spring. On a side note, my parents used to shingle in the 70's, many of times I had my pants legs nailed to the roof to keep me from falling off, I was 5 or 6 at time. Ahhh the good old days of no daycare...lol I have shingled a few roofs in my time, although never generally left felt on for a long period of time. (months) Seen many of t-locks installed in the OK panhandle till tornados started ripping them off in one big swoop..
Not necessarily, but yes. The specs call for "cover as soon as possible". I would not leave the roof tore off and dried in during your worst season of the year (if winter is that season, for us it is summer). The roof would be better protecting the way it is. You may be able to "temporary" some of the places to get through the winter, and then plan on tear off to the plywood after that season ends. Also the timeline would be much easier to deal with in case you can't finish in a hurry. Never installed T locks but I know they are for high wind areas. It always helps to read the instructions, all the manufacturers have them.
Great info, I'm new to roofing, first time. I have a question, where can I find Washington state code for felt roofing. What is the required code to nail felt on roof top, how many inches apart to nail a roof felt?. Thanks to your input.
You should start with the local town government. They may even have links on their website.
I just did a Google search for "Washington state code for felt roofing" and came up with this link:
www.seattle.gov/dpd/cs/groups/pan/@pan/documents/web_informational/s047846.pdf
I had some water damaged on fascia and edge board areas due to tarpaper were too short. How can I add new paper to do proper drip edge. I guess I have to remove tiles along the edge maybe up to 2 rows and put new paper in with drip edge.
Yes, would be better to remove a couple of rows.
Hi. I would like to ask you, please, I have corrugated metal sheets roof on the shed I am using.
Is this still an option for that kind of the roof?
It is possible. Depending on where you live. If you know the manufacturer, then make sure that system is approved in your area and follow the manufacturers installation recommendations.
Can you cold lap over the entire felt if you are laying down rolled roofing? Or do you just lap cement the seams?
Yes, fully adhered. Nail off the tarpaper better. Granulated modified bitumen cap sheet will last longer than organic rolled roofing.
Can this method be used to cover an entire roof or a house? Or is it used just for certain sections of a roof?
Yes, you can cover an entire roof or a house with tarpaper. However, it is not a finished roof. It is several things, a separation sheet between the roof covering and the plywood, and is also a temporary covering between installing the plywood and installing the roof covering.
Does Florida code call for taped seams on roofs prior to paper these days?
I believe one may conclude that 30# tarpaper will qualify as a secondary water resistance according to FBC, Existing Building 2017 - 706.7.2. However, the insurance companies are looking for, at a minimum taped seams, and would prefer a full self-adhered underlayment in order to get discounts. It would be best to consult with the insurance company before making any decisions. Also, you may contact a home inspector that handles the Wind Mitigation Inspections.
Where can I search for building codes for my state. I live in Texas and I wanted to get a copy of the building codes for when building sheds... roofs... and putting shingle. I'm not a roofer but I wanted to make sure I'm complying with the codes. NICE VIDEO!!!

Here is a video I did using this website regarding dripedge over or under dry in.
czcams.com/video/JmV5c52MUEI/video.html
Is there a top and bottom concept to the tar paper? Eg, you unrolled it in a way where the side that was on the outside of the roll, becomes the underside on the roof.
Yes, but I believe the only difference is there is lines on the "top" so you can see how far you lap it down, and also where to nail it. Normally, tarpaper is unrolled right onto the roof.
Is this nail going through stick out to the other side?
It will poke through just a little. 1/2" plywood.
hi. i am in sw florida and getting a new roof. the salesman is pressuring me to use peel and stick on the whole roof instead of synthetic felt. he says everyone in florida does it that way now. its an extra $1000. im about 2 miles off the gulf so not in danger of a direct hurricane hit. its a 2006 house so its already up to 130 mph codes. what do you think?
Go with the self adhered. Make sure you get another wind mitigation inspection after the roof is done and you should get an extra discount on your insurance. You may be able to see what it will be beforehand.
How do I install tar paper on a repair where I replaced the wood underneath? I just had to patch 2 x 2 piece of wood and I want to replace the tar paper as well?
Same, except on a smaller scale and you would want to get your paper underneath the existing.
Practical Roofing Concepts How far underneath on the top as well as the sides would you suggest?
6" would be ideal. As far as you can otherwise. Roofing cement will help. Even if you have an inch, roofing cement will bond the seam together.
👍👍👍👍👍
Do you install drip edge before or after the felt?
Depends on your area. In Florida it is common practice to install the dripedge on top of the paper and then seal with roofing cement. The roofing cement also bonds to the starter and keeps the shingles better "stuck" to the edge. If you're not in Florida, you should probably follow the code and install the paper over the dripedge. I would use a slip sheet so you're not installing the dripedge directly over wood.
Is synthetic better then 30 pound felt?
After the building code requirements, it is really a matter of preference. It has to be installed, it has to weather until the new roof gets installed over. As well as how easy is it to walk on, etc. Personally, I would prefer 30# with sufficient nailing. I know I can keep it dry during the time the roof is dried in to the time the roof is finished.
What kind of nails? I got a nail gun, use that or just hammer?
I don't think there is a gun for the metal cap nails, but believe there is one for plasti-caps. Those are 1" cap nails.
What's the difference between 30 lb tar paper and synthetic underlayment?
It really depends on the installers, the cost, the type of finished roof, and if it is acceptable to use in the area in question. Otherwise, I would say it would be preference of installation of the underlayment, and then preference of which underlayment is better to work on.
I don't really have experience with synthetic underlayments. I know some can be slippery, which may be a concern. We have all but stopped using 30#, except on repairs and have switched over to self adhered material. most are asphalt (modified) based.
Can I ask what size of nail is that?
1" cap nail.
Why would plastic cap nails not pass code in some areas?
They don't have the uplift apparently. We use them on metal roofs to keep the metal from touching the nails.
Should of put dripedge metal before paper on the bottom
No, not in the south. Possibly in your area. Roofing cement provides this same concept and also wind resistance for the first row of shingles and the rake edges.
So you dont need to put tar if its tarpaper?
The tarpaper is just separating the roof covering from the roof substrate (plywood). Also the tarpaper is a temporary dry in between the time the plywood is installed and the final roof covering is installed.
@@PracticalRoofingConcepts thanks for the reply I appreciate it
Nicely made video, thanks. Question on all the nails: why? Are you required to do this if you are installing shingles on the same day or is this just for if there is a delay?
I'm having a hard time imagining those nails making any difference once shingles are installed.
It's code. It has to do with when the shingles blow off in a hurricane, then the tarpaper should remain and limit damage due to rain. After Hurricane Andrew in 1992, the codes became a lot more stringent.
What were the name of those nails?
cap nails
Metal shank hammers will destroy your elbow eventually. I know from experience.
Will keep in mind. Have not heard that before.
Never heard that before but it makes sense since wood shank would absorb the shock where the metal would transfer it to your hand.
Clearly, you’ve done this before.
Why so many nail? And how come the nail are not under the upper later? More penetration thru paper, more risk of water leak.
It's code. The nails hold the paper in place for wind resistance while waiting for the shingles, and also so the paper won't slide out while we walk on it. Once the shingles go on, the paper becomes secondary. There will be more holes when the shingles are installed.
Why is the roof WOBBLY ? You need to put the Metal Drip Edge first !!
Metal on bare wood can also rot the wood. Florida Building Code allows dripedge to be under or over the tarpaper. We use roofing cement to seal the drip to the tarpaper and the starter will bond to the dripedge. Since we don't have to worry about ice, if the water gets past the shingles we have lost already anyway. The tarpaper is a secondary and now they are seeing the tarpaper as the layer that keeps most of the water out after the shingles blow off - We are now using mostly self adhered underlayment under shingles.
That's not exactly what the shingle manufacturers recommend. The manufacturers specify how to install paper and drip edges on the reverse side of the shingle wrapping paper. You really should refer to that before making a video for people.
You're right about that. Did a little research, check out this video czcams.com/video/JmV5c52MUEI/video.html . This is south Florida and this is the way it is done. Actually, now everything is self adhered right to the deck anymore. The entire roof, not just the edges. We are still installing the drip edge over the underlayment, even on the self adhered and sealing the joint with roofing cement. Seems to work better that way. There is no threat of ice damming or even snow. We get an occasional light frost every few years. That is the primary reason for installing the underlayment over the dripedge at the eaves. Thank you.
