Hi We had our California house fumigated a couple months ago.
We used Clark Pest Control -they have a 3rd party come out and do the job.
I’d call a pest control company first, tell them about your roof, and see what they suggest.
A fair warning.. prepping for fumigation is a LOT of work and you need to be out of your home for a few days.
If you have any questions, feel free to ask

With an about 20 yr old roof, I wouldnt take the word of a realtor, nor a trusted neighbor on that roof. Call in a reliable roofing company and have it inspected.

SMH... have you seen any termites/wings/ droppings? A roofer does not deal with termite treatment. And a termite company does not repair roofs. Unless your neighbor is a roofer, which I doubt, call a roofing AND termite treatment company.

Thanks for the suggestions.

I do not see any termites/wings/ droppings. But when I had bought this house 3 years back, the seller had done termite repairs on the roof worth about $750. Hence I am cautious.

Do I need to start with a general pest control, or termite treatment company?

Since you live in a termite area you should be getting yearly inspections for termites. I would call a termite treatment company, they will also do inspections.

Also should I get the overall inspection done first, or is it better to directly go to termite treatment company and a roofer?

First of all, most pest control companies do both inspection and treatment, and many do repairs as well. Ask your realtor and/or neighbors for recommendations. I am not a fan of the big national names that are franchises. Local companies tend to rely more on word-of-mouth recommendations. Expect to pay a separate fee upfront for an inspection, but that will not obligate you to use that company for the treatment/repairs. You can take the report and get bids from other companies for treatment. So yes, start with an inspection, pay for that.

As for a roof, get a roofing contractor to do an inspection.

Thanks for the replies.

I was browsing on the Internet, and realized that there are health risks with termite treatment. I am not looking to get the house fumigated. But even other forms of the treatment has lot of chemicals. Do people usually get these treatments done while living in the house?

It depends upon what they find, and how bad the problem is. A yearly spraying, under your house and around the outside, is what they usually do, but, if you already have them, then, they have to be treated inside too. You have no way of knowing any of that until you have it inspected and they tell you.

Also, for us, Termites were found when we lifted area rugs up. The inspectors know what to look for.
