All you have to do is file DOS 1746. Show that the course is approved in another state, send a letter stating you would like the credit and a certificate of completion and they'll approve it. Just look up what states take NACHI's online courses and submit your paperwork for approval. It might take a few weeks, so do it ASAP, just in case you file incorrectly, if you require it by 12/31/09 for your license renewel. No need to pay for expensive courses and drive anywhere.

InterNACHI and NACH TV have partnered to produce seven major roofing courses:

WIND & HAIL
This course is designed to teach home inspectors to perform onsite inspections for the insurance industry. InterNACHI has partnered and is working out the details with major insurance companies.

ROOF DEFECT RECOGNITION
This course is designed to teach inspectors how to inspect the five major steep slope roofing materials.

Asphalt composition shingles
Wood shingles and shakes
Concrete and clay tiles
Metal roofs
Slate roofs

Successful completion of these two courses will qualify the student as an InterNACHI-certified Roof Inspector.

We will also be producing individual courses on each of these five roof-covering materials which will each include wind and hail damage. Successful completion of all five courses will also qualify the student as an InterNACHI-certified Roof Inspector.

In adddition to video, we are working with a library of almost 7000 high-quality still photographs, most taken specifically for this course.

No other roof courses of this quality are available anywhere.

Here are the rough Tables of Contents for both main courses taken directly from the scripts
