It is a fair question, and most people do not ask it out loud. A technician shows up for a rodent problem, pulls a ladder off the truck, and heads for the roof. If you have barrel tile, you are now watching someone walk across the most expensive and most breakable surface on your house.
So here is what is actually happening up there, and what to ask before anyone goes up.
The bottom line
Roof rats enter at the roofline rather than at ground level, so rodent exclusion work cannot be done from the driveway.
Barrel tile breaks in predictable places, and the people who work on tile regularly know where to step and where not to.
Ladder work is the part of this job most likely to go wrong, which is why it gets trained rather than assumed.
Before anyone climbs onto your roof, there are three questions worth asking, and they apply to any company, not just ours.
Because that is where the problem is. UF/IFAS documents roof rats as climbers that travel along branches, fence lines and utility wires and enter structures near the roofline rather than at the foundation.
That means the openings that matter are ones you cannot see from the ground. Separated or lifted soffit panels. Gaps where plumbing vents pass through. Lifted or cracked tile. The junction between gutter and fascia. Old satellite dish mounts nobody removed. Attic vents with torn screening.
The same is true for several other common calls. Wasps coming out of soffit vents are usually nesting in a void you reach from a ladder, which we covered in our article on wasps in soffit vents. Attic inspections start at the access point, and what turns up in South Florida attics is rarely visible any other way.
A company that never goes above head height is treating what it can see. Our guide to rodent work before the season covers why sealing, not trapping, is the part that lasts.
Not randomly. Barrel tile is strong where it is supported and weak where it is not, and the difference is a few inches.
The unsupported span.
Each tile overlaps the one below it. The section spanning open air between support points is where weight cracks it. Step there and you hear it.
The edges and the nose.
The lower lip of a tile and the outer edges carry the least support and chip easily, including from a ladder set against them rather than against the fascia or a stabiliser.
Age and sun.
South Florida tile that has been through twenty years of heat and UV is more brittle than it looks, and older concrete tile can fail under a load it would have carried when new.
Moving wrong.
Most damage happens during transitions, getting on and off the ladder, turning, or carrying something while not watching footing. That is exactly why the ladder part gets trained rather than picked up on the job.
You can tell a lot without going up there yourself.
The ladder is set at a sensible angle and footed on level ground, not propped on a planter or a slope. It rests against fascia or a stabiliser bar rather than directly on tile or gutter. The technician is not carrying equipment up in their hands while climbing. Movement on the roof is deliberate and slow rather than quick and confident.
OSHA publishes ladder safety requirements for exactly these conditions, and the basics are not complicated. They are just easy to skip when someone is in a hurry.
These apply to any company, including this one. Ask them before work starts rather than afterwards.
1. Does roof access need to happen at all for my problem?
For a rodent exclusion job, almost certainly yes. For a general quarterly service, probably not. A technician who can explain why they need to be up there has a reason. One who cannot should stay on the ground.
2. What are you going to do once you are up there?
The answer should be specific. Checking soffit seams, vent screening, tile condition at the valleys, the gutter and fascia junction. "Having a look around" is not an answer.
3. What happens if a tile cracks?
Ask it directly, before the ladder goes up, and get the answer from the company rather than the individual technician. Any firm doing this work regularly will have a clear response ready. Hesitation is the useful signal here.
New technicians at Wise House train before they work on customer homes. Ladder setup, footing, transfer on and off a roof, and how to move on tile are part of that, taught by the owner rather than left to be figured out.
It is not glamorous and it does not appear on any service list. It is just the difference between a technician who can inspect your whole structure and one who inspects the half of it they can reach.
If something is moving in your ceiling at night, the work is at the roofline and the inspection has to go there. Wise House Pest Control offers a free inspection across Palm Beach County, Martin County, and St. Lucie County.
