"If I could give them 10 stars I would. I had Garden State Home Remodeling come to pave my old torn up driveway and yard space and replace with asphalt.

Roofing questions, answered by experts

Technically, a flat roof can be raised, but it’s extremely expensive, and there would not be much of a point. Most homeowners raise the roof in their homes to access the space between their existing ceiling and the roof, but flat roofs don’t have this space. Therefore, you can raise a flat roof, but it involves heavy structural modification.

Roof repairs average around $1,100 but can easily exceed that for larger repairs. The cost of roof replacement depends on the size of your home and the materials used but averages between $4,000 and $24,000.

While you can technically install TPO roofing over an existing roof, it isn't always wise to do so. The more layers of material you add to your roof, the more weight it must support. You may also develop moisture issues by covering your existing roof with TPO. Your local building codes and regulations may actually require you to remove the existing roof before adding TPO, so check with your local municipality.

While you technically can add a roof over shakes or shingles, it’s not a good idea. Roofing over existing roofing creates a moisture barrier underneath the new roof and since the trapped material is wood, you can expect a moisture problem. While you could get away with installing a new roof over asphalt or steel, wooden roofs should be removed, new underlayment installed, and the new roof installed over that. Also, the extra weight would add strain to your roof structure.

Re-roofing is the process of placing a layer of shingles over top of existing shingles, rather than pulling out those shingles and replacing them. Compared to a full roof replacement, re-roofing typically costs less and requires less labor and time. It's not an option for everyone, though. You may need a full roof replacement if your roof already has more than one layer of shingles. A full replacement may also be necessary if your roof has extensive damage.
