The amount of hurricane damage that happens to your roof is pretty much dependent on the type of roofing materials used and how well they were installed. There has been a lot of controversy over distinguishing between hurricane damage and pre-existing problems when home owners file an insurance claim.
When assessing a roof after a hurricane, the investigator or roof repair contractor needs to have in-depth knowledge of installation methods, and how the weather affects the natural deterioration of the roofing materials. It's also necessary to be aware of how wind affects the roof.
The same air flow that happens over the wing of an airplane takes place over the roof during a hurricane. It does not happen uniformly. The greatest force is at the windward edges, the eaves, the corners and the rakes. This is where most wind damage starts on a roof. Then the uplift causes internal positive pressure that literally blows the roof apart.
The best preventative measure is to anchor the roof properly to the walls to resist the uplift. It must braced against the trusses to transfer the lateral load. Keeping the roof intact prevents the rest of the house from caving in or being doused with hundreds of gallons of water.
The more weathered the roof, the worse it will fare in a severe storm. Cracked or "alligatored" roofing compound used to seal seams and flashing easily get washed away in a heavy downpour, leaving material edges exposed to the wind. There is no "magic" to preventing hurricane damage - it's a matter of keeping your roof in good repair.

WOW! We had a very hard to pinpoint leak in the foundation wall under our garage. I was concerned it was the foundation leaking in water as it came through a crack. Steve came out the same day and used an infrared to trace the leak all the way up to the heat stack pipes on the roof. The water was running down the pipes and finding it's way out in the basement. The crew came out the SAME DAY and fixed the flashing and ridge to make sure we sealed those areas. As of now, we need another hard rain to confirm the leak is stopped, but are confident. I was told not to patch the small crack in the wall as that is our guide to ensure no more water..thats confidence in your work! 6 month warranty, and a promise to come back if the leak still exists. Im VERY pleased...speed, good price and honesty. Now wait for rain, and close the loop on this mystery basement leak...
