There are two sides to every story—but what some homeowners may not realize is that there are also two sides to most roofs, too. Beyond the professionally installed roofing system that protects your house from water on the outside, an attic ventilation system works from the inside to protect your home from heat and moisture.
When buying a new roof, it is important to understand what kind of warranty you will receive when the job is complete. All reputable roofing manufacturers will offer some basic warranty coverage against manufacturing defects in the roofing materials, but oftentimes there may be enhanced warranty offerings available either through the roofing contractor, or through the roofing manufacturer. You should make sure to discuss your options with your roofing contractor before making a decision. Here's what you need to know when selecting your warranty:
Starting a new roofing project can introduce homeowners to many roofing-specific terms, and one of the first you're likely to come up against is "roofing square." Measuring in squares is unique to the roofing industry—for homeowners, understanding how these measurements work can be an unfamiliar but vital part of planning for your roof repair or replacement.
Do leaks or roof damage have you wondering if it's time for a roof repair or replacement? You may need to call on a roofing contractor. So, don't panic—but don't delay, either. The roof is your home's first line of defense against the elements, and you want it to stay in prime condition.
