"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."

"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

The installation may have been done correctly. However, improperly installed gutter guards can easily damage your shingles. Also, cheap gutter guards rarely come with installation fixtures. In the worst cases, they simply ask you to nail the guards in, which would sabotage your roof’s water resistance and thus void the warranty. To be sure, always check with your home warranty provider before making any modifications.

A spray foam roof lasts 20 to 30 years if installed and maintained correctly. Spray foam roofs should be recoated every 10 to 15 years to maintain the UV protection and waterproof surface of the foam material. The longevity of spray foam roofing will depend on the thickness and density of the foam, the protective coating, and how well it’s maintained.

No, you can’t use your home’s square footage. You have to calculate your roof’s square footage, and then you may have to convert your square footage measurement to correspond with how the roofing material is measured. For instance, some roofing is sold in “squares,” which equals the total square footage of the roof divided by 100. Shingles are sold in bundles that may not correspond to the number of squares you need. Metal roofing is sold as sheets, so determine the amount of square feet each panel will cover and then divide the total square footage by the coverage area.

Yes, copper roof strips can help prevent shingle damage and are an alternative to algae-resistant shingles. They work in a similar way: they release copper ions that interfere with algae, moss, and other plant growth. Algae feeds on limestone in your roof shingles, and moss can uplift shingles and increase the risk of leaks. If you have issues with algae or moss on your roof, copper roof strips can help avoid damage.

Though people use the terms interchangeably, there are some notable differences between wood shakes and shingles. Wood shakes are hand-split from trees and thus have a more textured appearance. They’re also usually thicker (and may not be perfectly uniform). Wood shingles are smoother, thinner, and more uniform than wood shakes.
