Get matched with top roofers in Dinwiddie, VA

Installing a green roof costs between $10 and $30 per square foot. Green roofs cost slightly more than standard roofs, due to the extra materials and installation know-how required. The type of green roof you choose also impacts the cost, with intensive roofing systems costing considerably more than extensive roofs.

Condensation can occur on the inside of a roof, but it should always be temporary. It does not necessarily mean there is a roof leak. Condensation happens when the inside and outside of a house are at different temperatures. For instance, if it is hot during the day and then gets very cold at night, the inside of the house will be warmer than the outside and may cause condensation to form on the inside of the attic. This may not be cause for concern, but if it is happening frequently, it should be addressed; otherwise, it could cause roof leaks, compromise the structural integrity of the wood, or allow mold to grow.

There should be small gaps between your roof and the walls of your home, and other buildings. These small gaps let building materials shift, expand, and contract with weather and other outside forces, and they prevent moisture from wicking down walls from roofing and gutter systems. Without these strategic gaps, your home’s exterior and its finishes can sustain water damage, decay, peel, delaminate, and crack. However, there is a fine line between a smart gap and a problematic gap—all  gaps should be small, intentional, and covered or filled in with foam insulation to prevent pests from using them as access points.

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.
