Properly fastened Architectural shingles can withstand winds up to 130MPH
I say this as a licensed, insured, certified and bonded roof and wind mitigation inspector(among a pile of other certifications).
You are more likely to have your roof just toe-nailed to the wall which will let go before architectural shingles do.
If you’re going to get re-roofed, pay for hurricane straps or clips to be added during the re-roof. You can probably get a discount if your insurance provider gives credit for wind mitigation.
This, exactly this.
I have hurricane clips on half the rafters in my roof, but not all of them, so I guess I will add them to the rest of the rafters after this season is over. I should have the money for it then.
Second Malsua’s comments, and would add to the concept of nailed to wall shingles will not last:
If getting a complete re-roof (strip off old everything), there is something from the post Hurricane Andrew time, called “Dade County Code” underlayment. It is a tough fiber woven rubberized underlayment that is glued to the (at least in FL) marine grade plywood, to which properly affixed shingles are attached, ideally with a glue to the underlayment. This is not inexpensive however.
In sustained 130 mph winds (like Andrew CAT 5 did in certain areas) the shingles may come off but underneath the underlayment maintains the roof integrity.
If you are talking about tornadoes— the clips mentioned are essential strengthening- otherwise the roof itself can blow completely off (poorly stick built and how the rafters/trusses are installed critical as well).
From experience- Carribean life with intense hurricane impact. For recent review- see: Fort Meyers Beach,FL— incredible.
Not to hijack the thread, but when we lived in Guam you could not get homeowners insurance for any shingle or metal roof. To get insurance you had to have a concrete roof at least 8 inches thick.
Our house had 125 mph wind-rated window glass AND mollies in the outside wall to fasten 3/4 inch plywood for typhoon shutters that were kept in the shed. The walls were reinforced cinder block construction with a poured concrete roof 8 inches thick. All floors were ceramic so minor flooding was not an issue.
The house looked like a machinegun bunker but I felt safe in a typhoon
In Ohio, we just had roof stripped and replaced and the cost of the Hurricane Shingles added a small amount to the $15,000 job, maybe $250 at most. I think it was worth it as we don’t get Hurricanes per se, but in 2008 the remnants of Hurricane Ike swept thru the Ohio Valley one Sunday and did all kinds of damage, we lost a few shingles and part of a fence plus electric was out for almost 5 days. I’d pay the extra just for peace of mind. Those Hurricane shingles really glue themselves down tight.
