Roofing questions, answered by experts

Yes, moss can be dangerous for your roof if left in place to grow without treatment. The moss soaks up and holds moisture. Having a constantly damp roof could lead to problems with rot for the parts of the roof that consist of wood. Additionally, a patch of thick moss may draw insects and birds, which could damage the roof. Thick moss could block the roof’s drainage system. Water then may back up after a rainstorm and cause further damage that could eventually lead to roof repair expenses or the cost of roof replacement.

Installing solar panels involves drilling small holes in your roof to secure the solar panel mounting brackets. These brackets hold the solar panels in place and must withstand strong weather conditions so they’re secured into your roof. However, holes and screws are sealed to prevent leaking and further damage.

Always inform your insurance company when you get a new roof. A new roof may entitle you to lower rates or discounts, and if you need to make a claim, they’ll have up-to-date information on your roof. You’ll need to provide documentation—ask your insurance agent what you need to submit to prove you had your roof replaced.

Yes, gable vents can let water in. That being said, this usually only occurs during extreme conditions like heavy rainfall. You can prevent water from entering through gable vents by adding a screen that traps the water before it can enter.

Most roofs can take quite a bit of weight from snow, but their ability to handle heavy snow is not unlimited. Most roofs can handle about 20 pounds per cubic foot of fresh snow. Ice, ice dams, and other factors can contribute to dangerous roof weight. Newer roofs, sloped roofs, and those that have more support can hold more snow than older roofs, flat roofs, and roofs with widely spaced beams. To figure out how much snow your roof can hold, you will need to contact a professional roofing contractor to calculate the maximum snow load for your specific roof.
