Roofing FAQs, answered by experts

You should tarp a roof whenever roof damage occurs. Missing shingles and holes in your roof can cause roof leaks and problems that come with them. Tarping is a quick way to provide temporary roof protection while you wait for a professional roofer to make repairs.

The most common roof pitch is 4:12, which means a rise of 4 inches for every 12 inches of horizontal run. However, roof pitch varies widely based on roof design, climate, and even the roofing materials you plan to install. Your building type also plays a role, as flat roofs are common on commercial buildings and some modern homes.

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.

Building code allows 24-inch on-center spacing for roof trusses. However, you can install them on 12- or 16-inch centers to handle large loads or other exceptional circumstances. In cases such as covering a wide span or supporting alternative roofing materials, where a structural engineer needs to evaluate or create a design for your trusses, the plans will indicate the spacing. 

You can install solar panels on a flat or pitched roof, but keep in mind that they will need to rest at a 30- to 50-degree tilt for optimal sun absorption. It costs more to install solar panels on a flat roof because you will need to install a framing system and likely hire a structural engineer. If your roof has a pitch of more than 40 degrees, it may not be a good candidate for solar panels.
