Roofing FAQs, answered by experts

Roofers can install roof vents. Updating, upgrading, or simply replacing your roof's existing vents is common when installing a new roof. If you're looking to upgrade your ventilation system with a powered version, a local HVAC professional can also help with the task. If adding roof vents to your home is necessary while installing an addition or during other renovation work, your contractor will handle or hire out the venting work.

The lifespan of asphalt shingles is typically between 15 and 30 years, depending on the type of shingle and other factors. Standard 3-tab shingles have the shortest lifespan, around 10 to 15 years. Architectural shingles last longer, averaging 20 to 25 years. Luxury or designer asphalt shingles are the most durable, with a lifespan of 40 years or more. Climate, installation quality, and regular maintenance also play a significant role in how long your shingles will last. Signs that they need replacement include granule loss, bald spots, and roof leaks.

In most cases, installing solar panels will not void your roof warranty. To keep roof warranties intact, check your written warranty or call the manufacturer to ask about clauses regarding roof penetrations. You can also protect yourself by getting written approval or a modified warranty that specifically allows the solar installation type you’re planning. Then, hire a professional solar installer that follows roofing manufacturer instructions and protects the roof during installation.

Many homeowners believe that a modern home looks better with a flat roof than a sloped roof. A flat roof can provide several aesthetic benefits for modern homes. Among the pros and cons of a flat roof for a modern home design are the clean lines and straight edges that it delivers to improve curb appeal.

Technically speaking, yes, verbal agreements and “handshake deals” can be legally binding contracts that will hold up in court, but the suing party will need to be able to prove that the parties entered into the contract. Even though verbal and handshake deals can be binding, it’s risky to rely on these types of agreements for anything, including roofing projects. Always aim to get your contract in writing, and make sure it includes all terms and that you don’t agree to additional terms that don’t appear in the contract.
