They kept the worksite clean, communicated clearly throughout the project, and completed the job on schedule. The quality of workmanship exceeded my expectations, and my new roof looks fantastic.

Roofing questions, answered by experts

Underlayment is required by building code, so any roof installed without it is technically against code. The underlayment acts as the second layer of defense against water, so installing a roof without underlayment means a much higher risk of roof leaks. You’ll have the best chance of avoiding roof leaks if you install drip edge flashing covered by underlayment, and then install your roofing material over that.

It’s possible for a roofing estimate to change after the initial assessment, but in most cases, it shouldn’t. There’s always the risk that something unexpected will happen that causes prices to go up, like discontinued materials or your roofer discovering previously hidden damage to your decking when ripping off the old roof. However, experienced roofers should account for these circumstances in their initial estimates. Roofing contracts are binding, so always check your contract for language about how and why your numbers could change.

TPO roofing can last anywhere from 15 to 30 years, or an average of 22 years, but you can extend its life expectancy through proper roof maintenance. For the best chance at realizing the longest life span possible, keep tree branches trimmed so they’re not in contact with the roofing material. Inspect your roof regularly and repair any damage immediately.

A properly installed, high-quality tarp can be left on a roof for up to 90 days. However, this is only a temporary measure and not a substitute for proper roof repair or replacement. Thinner tarps or those exposed to heavy wind and rain may not last the full 90 days, so it's important to monitor the tarp's condition to ensure it continues to protect your roof from the elements.

Concrete tile roofs last for an average of 50 years, but you could see more than that if you’re diligent about repairs, roof inspections, and maintenance to avoid major damages. Concrete tile roofs are prone to cracking, so they may not last as long without needing repairs in areas with extreme weather, especially hail.
