Is re roofing a good idea?
Then, is it OK to put a new roof over an old one?
The answer is yes, you can lay new roof shingles over old ones. But before we get started, one thing must be clear: adding new roofing over old (sometimes called a "re-roof") is possible only with asphalt shingles (also called "composition shingles").
Also, how long does a roof overlay last? A typical 3-tab asphalt shingle roof will last anywhere from 10 to 20 years. 3-tab shingles are an OK option for temperate climates, but they are not at all suitable for storm-prone areas.
Beside above, is it better to repair or replace a roof?
If the roof is damaged but most of it is still in good shape, a spot repair may make sense. But, if the roof is approaching (or past) 20 years old, replacing it may be the better way to go long-term. If the roof is leaking in several places, a roofing replacement may be in order.
What is the difference between re roof and new roof?
Re-roofing is the process of layering new shingles on top of already existing ones. If re-roofing is not an option, then your next option is a complete roof replacement. Roof replacement can be done at any time but especially if there are problems with the roof deck.
