This may only last a year or two with extreme temperatures and changes in the way it's used. However, if your garage door doesn't change much and the use of the seal is relatively consistent, it could last much longer, more than 2 years. You'll know when to change the seal by looking at a few things. The door gasket should move a little if you push it with your fingers.
Over time, exposure to sunlight causes rubber to become stiff and brittle. If you notice resistance when pressing on the rubber door gasket, you should replace it. Stiffness and brittleness will soon cause the rubber seal to crack. All types of weatherstripe shrink, crack, and peel off surfaces over time.
Weather seals for garage doors are no exception. The things they're designed to prevent entry to are also the same things that contribute to wear and tear. A good habit is to check the seals around the garage door every year before it gets too cold. This is because the impact of the door against the floor is greater than the friction on the sides of the door.
In winter, this lubricant will cause water to accumulate and will prevent ice from forming on the door throughout the winter. Instead of placing a wider rubber band under the door, which could cause premature wear of the weather seal, install a storm protector. Every time the garage door closes and hits the garage floor, the damage to the gasket will increase. Because the inner side of the door is warm and the outside of the door is very cold, a thermal break will occur between the outside and the inside due to the polyurethane insulation.
In most cases, garage doors are created so that components can be changed or repaired individually. For example, Garaga InterlokTM gaskets have three points of contact that ensure that air, light and even water do not pass through the door. The only exceptions are when it is necessary to keep the garage very warm in winter or when the garage is used as a workshop. The best thing to do is to thoroughly clean the door no less than twice a year to keep it in good condition.
For example, if there isn't any weatherstripe on the top, but you want to add it, a garage door specialist can provide you with more information about the process. The seals for the top and sides of a garage door take the form of flexible strips of neoprene rubber with a crease in the center, giving them a V-shape. Most people make the mistake of thinking that a door's insulation is only calculated with the R value. Even the best possible insulation won't help much if the wind can pass through an inch of space around the door.
Likewise, for any needs you may have with the three categories of weatherstrippers mentioned above, you can find all the necessary parts at your garage door specialist. If it ever breaks, whether due to an accident or due to the wear and tear of time, contact a professional so that your door can be properly repaired.
