"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."

Cobex Construction Group is your 5-Star trusted exterior contractor for Roofing , Siding and Windows. We are a local family owned home improvement company with a combined 30 years of experience in home improvement and construction. Our company principle is "people before profit" we believe in the saying ?Do it once, Do it right?

"I live in a home owners association. One of the roofers got a speeding ticket. The project manager said the Company would pay the fine. A month and two emails later radio silence and no effort to pay the fine. Can't judge the workmanship since it hasn't rained enough to test the roof. However, given the companies failure to live up to the representation of the project manager and their failure to respond to my emails over such a simple issue, I anticipate problems will be forthcoming."

FAQs for asphalt shingle roofing installation and replacement projects in Discovery Bay, CA

Roofing professionals can usually install a medium-sized asphalt shingle roof in two to three days. Installation time increases if your roof is particularly steep or difficult to access or has features like chimneys or skylights that roofers must work around.

Three-tab asphalt shingles usually have the lowest upfront cost of any roofing shingle material. They’re sturdy and typically last 15 to 20 years. However, they may have a shorter lifespan in especially hot or cold climates. Talk to a local roofing professional about the best materials for your climate. In some cases, materials with a higher upfront cost may save you more on repairs or replacements in the long run.

Start by multiplying the length by the width of your roof to calculate the square footage. Most shingle replacement costs $4 to $12 per square foot for materials and labor, depending on factors like the material and the slope of your roof. Once you know the size of your roof, you can calculate a rough estimate of total costs or contact a local roofing professional to provide you with a custom quote.

Asphalt shingles are generally considered to be a low-maintenance item. However, cleaning your asphalt roofing can help prolong the lifespan and keep it looking fresh. If you’re comfortable with DIY and have the proper equipment, you may be able to clean your asphalt shingles yourself. However, if you have an especially high or steep roof, it’s usually safer to hire a professional roof cleaner.
