There is very little difference.
In February of 2007 the Fujita or "F" scale was replaced with the Enhanced Fujita or "EF" scale. The EF scale uses more detailed analysis of damage than the original F scale so that tornadoes can be rated more accurately. The EF scale also provides different estimates of wind speeds for the degrees of damage.
So EF1 damage is essentially the same as F1 damage but it may be examined in greater detail.
Additionally F1 wind estimates range from 73 mph to 112 mph while EF1 wind estimates range from 86 mph to 110 mph.
Estimated wind speeds for an F1 tornado on the original Fujita Scale are 73-112 mph. These were found to be inaccurate, though, and were adjusted to 86-110 mph for an EF1 tornado.
Yes, there have been tornadoes in Wolcott, Connecticut. The most recent tornado in Wolcott occurred on May 15, 2018, rated EF1. Wolcott has experienced a few tornadoes in its history, with varying intensity levels.
On the original Fujita scale the top wind es for an F1 tornado were set at 112 mph. Winds estimates on the more accurate Enhanced Fujita scale were adjusted for all categories, but the upper bound for anEF1 tornado was shifted only slightly to 110 mph.
An F5 tornado does not form directly from an F1 tornado. Tornado intensity is determined by the Enhanced Fujita Scale based on wind speeds and damage. It is possible for a tornado to rapidly intensify due to various atmospheric conditions, leading to an increase in intensity from an F1 to an F5 tornado.
An F1 tornado is considered weak, with wind speeds ranging from 73 to 112 mph. Damage caused by an F1 tornado can include broken tree branches, shingles blown off roofs, and overturned outdoor furniture. While it is not as destructive as stronger tornadoes, it can still pose a threat to people and property.
Tornado ratings are a reflection of intensity, not age. The first EF1 rating was assigned to a tornado on February 2, 2007, 1 day after the new scale went into effect. Prior to that a tornado of the same intensity would be rated F1. Since the new scale was implemented over 2,000 tornadoes have been rated EF1.
Estimated wind speeds for an F1 tornado on the original Fujita Scale are 73-112 mph. These were found to be inaccurate, though, and were adjusted to 86-110 mph for an EF1 tornado.
F1 tornadoes rarely kill, and when they do the death toll is rarely higher than 1 or 2. However, the deadliest F1 tornado to occur in the U.S. since records keeping began in 1950 killed 16 people. The deaths occurred when the tornado capsized a boat on Pomona Lake in Kansas. A similar, but far deadlier case occurred in China in 2015 when an EF1 tornado capsized a cruise ship on the Yangtze river, killing 442 people.

Usually it would take at least an F2/EF2 tornado to remove the roof from a house, but if it is not well secured and F1/EF1 could remove it.
On the original Fujita scale the top wind es for an F1 tornado were set at 112 mph. Winds estimates on the more accurate Enhanced Fujita scale were adjusted for all categories, but the upper bound for anEF1 tornado was shifted only slightly to 110 mph.
A tornado earns an F1 or EF1 rating if it causes moderate damage. This may include badly damaged roofs on houses, broken windows, snapped trees, and trailers overturned or partially destroyed.

F1 tornadoes can kill, but they rarely do. So an F1 tornado is unlikely to kill you, but you should still take safety precautions to reduce your risk, especially since you can't tell how strong a tornado is before it hits.
An F5 tornado does not form directly from an F1 tornado. Tornado intensity is determined by the Enhanced Fujita Scale based on wind speeds and damage. It is possible for a tornado to rapidly intensify due to various atmospheric conditions, leading to an increase in intensity from an F1 to an F5 tornado.
they are just different
F1 winds speeds are 71-112 miles per hour.
