So I have been making a quail coop and it has two sections, a covered coop area and an open area. For the covered area I plan to use shingles as I already have some on hand but the roof is only 3x4 and I can’t justify spending $40 on proper underlayment just to use 1% of it. So could I use a tarp instead? I have a tarp that I could cut to size and use instead but I am not sure if that is a good idea. Thanks!

I’m not certain that a tarp would provide adequate protection and may even be more damaging than using nothing. I’d take a drive through your town and look for construction sites. Underlayment is always thrown in dumpsters at job sites and I’m sure the workers would be glad to spare a piece. Just a thought.

So, are you a roofer? I ask because shingles are a skilled job, and involve a lot of materials. Done wrong, you are punching dozens of holes in your roof, every one of which can and will leak given opportunity to do so. Nails that aren't driven perpendicular yo the roof, that aren't drivenfar enough, or that are driven too far are the top three reasons for shingle roof leaks.

Done correctly, you need not only your left over shigles, and roofing nails, but also underlayment/felt , flashing, and plywood or other hard surface to nail thru.

Your local big box should have something like this. $16 and a few screws, you now have a solid cover with far fewer potential leaks, because you need far fewer screw holes. $8 in rubber washer equipped roofing screws and you are done.

Save the tarp for shading the run during the summer months.

How would just using the tarp over the wood work? I am fine with replacing it every year as it tarps are pretty cheap.
