Attaching tarp after blown off shingles.

I went with metal last year as well because the wind was lifting my shingles, and I didn't believe the claimed life expectancy of shingles. The downside to screw down metal roofs, however, is the sealing washers on screws are only good for maybe 10 years which creates another maintenance headache.

The main difference for me with the metal is that I'm not up on my roof every couple of months replacing shingles. If you have a shingle roof then this type of regular maintenance is required if you don't want to end up with rotten trusses and a bigger expense. The entire thing should also be replaced every 10 to 15 years, depending on the shingles. Most people, from my observation, do not take this into account and then they're surprised when the roofer tells them they have to rip up the sheathing and replace supports.

With the metal roof I occasionally go out when it's windy and look at/inspect the roof. If you have loose screws you'll know. From the right angle you'll be able to see the metal flexing. I watch my solar array the same way. The high winds I get tend to stretch the bolts holding the panels in place.

Anyway, like someone said, I don't know the OP's abilities, if I could not do it myself then I'd at least still keep eye on my roof and call the roofer immediately when needed. You should be fine though a rainstorm or two as long as the rain does not come with driving wind to push too much water under the shingles. Even then, as long as you don't leave your underlayment exposed for an extended amount of time you should be fine. In any case, for a few missing shingles I wouldn't be overly concerned unless it was going to be a long time before it was going to be fixed.

The roofer had to finish jobs that his crews had started before they could start to work on repairs. My daughter who works for an insurance agency said they were totally swamped with calls from wind damage. A friend had his entire equipment storage shed ripped from the ground and flipped over and wife's aunt lost several buildings with the 'telephone pole' sized supports snapped in half at ground level. So this was (hopefully) a once in a lifetime event. I covered the two spots on my roof with tarps. Then I took damaged shingles and put them back in place on daughter's roof. They were forecasting much rain here but the forecast was pushed back a day then when the rain came it wasn't as much as predicted. I used some small slats from Lowes that cost $1.17 each to anchor the tarps.

As you can see from the picture above the shingles were well nailed. The south end of the house where the damage is has trees that tend to funnel the wind across it. We have a patio nearby that always has a good breeze in the summer.
