The two loads that matter
UV is the first. It breaks down the surface oils in asphalt, which is why older shingles look dry and dull and stop shedding water. Heat cycling is the second: a roof surface gets very hot and cools overnight, every day, and a supple shingle absorbs that movement.
Then there is rain, which arrives in volume and often sideways. Where it lingers is where wear shows up first.
What a treatment does about it
Fortify is the UV shield and Fortify Elite is the same technology applied twice. The treatment works into the shingle so the surface sheds water rather than holding it, which is the same job the shingle was doing when it was new.
Neither reverses damage that has already happened. On a roof where the surface is largely gone, the answer is the bridge or a replacement, and the score decides which.
Where storms fit, and where they do not
Storm damage is excluded from the cover, on every row but one: the hail line of 5 years that sits on Fortify Elite in the Good band alongside its 20 years non-prorated.
A treated roof is not storm-proof, wind-proof or hurricane-proof, and this site does not claim any of those things. What the treatment does is make the surface shed water and slow the wear the sun causes.
Alabama service
Alabama is one of the three states we serve. No city in Alabama is confirmed on this site yet, so the address check is what settles it: send the address with the request and we will confirm coverage before anything is booked.
The state-to-climate matching used on this site is approximate and always overridable, because one state can span more than one pattern.
Before the storm season
The practical timing is to have the roof scored while the weather is dry enough to work, since the application needs 24 to 48 hours of dry weather to cure.
If the roof needs a repair, that is the moment to know it, rather than after the first storm finds it.
The question behind the question
When someone asks whether a treatment works in their state, they usually mean one of two things: will the heat beat it, or will the storms take it off. The answer to the first is that the range is built against UV, which is the force that does the drying.
The answer to the second is that a treated roof is not storm-proof, no claim is made that it is, and storm damage sits outside the cover on every row but the hail line.
