"Needed to have our roof replaced. Lifetime Roofing is great! Gui from Lifetime stopped by the same day I called in for an estimate, and he was able to get us a very competitive price. Gui regualrly checked in to provide us updates on the status (permitting, install progress, etc.) and to see if we had any questions or issues. The crew was fantastic. Clean and quick. The best part? The City of Mt. View told Lifetime to install 20 vents on a 2,500 square foot roof!!! Lifetime spent time with the inspector and got that down to 5 vents and ridge vents. Very helpful! Overall, a wonderful experience."

"We hired Francisco to repair our roof. When we called him, he promptly replied and came the next day to give an estimate for the job. The price he offered was very reasonable and the job was very well done. He takes his work very seriously and cares about the results. He even came to check on the roof the day after it was done to make sure it was doing well. I learned about Francisco and his services through my neighbors and we highly recommend him to anyone who needs foam roofing."

"This roofing job started off bad and continued to the finish. I wanted a professional with a few requirements. Be careful of original structure as it is prefabbed. The workers punched twelve holes in sheeting removing old roof material, requiring sheeting overlay. I requested that roofing nails not protrude through roof in patio area. They were protruding through the entire area. They left refuge sitting on the side of the driveway until I asked to have it removed. The one-week job turned into a two-month Odessey. The job was obviously a side job, piece-mealed together with little supervision little supervision. I am not confident the roof will not fail. prematurely fail. "

Roofing questions, answered by experts

Spray foam roofs don’t stand up well to impact, so they won’t last as long as something like a tar and gravel roof and other flat roof materials in areas where extreme weather is common. Due to the reduced durability, you’ll also need more frequent maintenance and repairs for a spray foam roof, and those costs will add up over time. Spray foam roofs are relatively uncommon, so you may also struggle to hire a roofing contractor who can install one.

The common formula for measuring a roof is length x width equals square footage. Professional roofers measure the length and width of your roof, including dormers, and determine its pitch and rafter sizes. If a roof surface is a triangle, they’ll divide that square footage by two, then add up the square footage of each surface to get the total for the roof.

You can leave a tarp of a roof for up to 90 days if installed correctly. Tarping a roof is only a temporary measure and should not be a substitute for roofing repair or replacement.

Yes, all roofs can benefit from flashing. Roof flashing can protect a property from water damage, roof leaks, mold, and other serious issues. It’s vital if you’d like to extend the lifespan of your roof and avoid costly repairs down the road.

There is a weight limit for walking on a roof, but it’s determined by your roof structure and not the roofing material, at least in the case of a metal roof. Consider that entire teams of roofers will be on top of your home during the installation, so the weight of a single person won’t compromise your roof. That isn’t the case for something like a tile roof, so a high weight limit is one benefit of a metal roof.
