Should I weatherproof a new roof?

Quick answer: Yes — weatherproof a new roof. You can’t be sure how much factory protection it has (some have little or none), and adding a dedicated coating won’t harm it. We recommend a long-lasting two-year soft-top coating; if you’ve just had a new roof kit fitted, treat it soon after so it sheds water from day one.

We think you should, because you really don't know what kind of weatherproof coating a new roof has on it. It may be a good one, it may have none at all. It does no harm to give it another coating. 

We put ceramic coatings on the paintwork of a lot of brand-new cars, some of which are convertibles. We recommend putting a two-year coating on the hood too.

Occasionally somebody brings a car to us with a soft top which is beyond restoration, and we recommend that once they have a new roof kit fitted, that they come back and have the hood treated.
