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.

A shingle roof costs between $7,500 and $24,000 in total. The exact cost depends on the size of your roof and the number of bundles of shingles required. A bundle of shingles typically costs between $40 and $60, though contractors might be able to get a lower price than you’d get buying from a local hardware store.

Rubber shingles last for around 30 years, on average, and some can last for and include warranties for up to 50 years. Rubber roof shingles are more expensive than asphalt shingles, but they can last up to twice as long, meaning they provide more value in the long run. Just keep in mind that rubber roofs often require more maintenance than asphalt shingle roofs, including routine cleaning to avoid mold growth. Ask the roofer who installed your roof for an estimate for routine cleaning, if necessary.

You should plan on waiting as long as it takes for the roof deck to dry out completely if it gets wet. In most cases, this will take about 24 hours, but it could take longer if you have shading on your roof or cloudy weather after the rainfall that prevents the sun from drying the material.
