"Pete (the owner) and his roofing crew (Genaro, Alberto, Pedro) were great! Pete replied promptly to my initial inquiry and came out right away to look at the roof. Following that, it took somewhat longer than I had hoped to get an initial bid and to actually start the job, but his bid turned out to be lower than the others, and I could see that the delay was for the right reason -- Pete always prioritizes the roof he's already working on to make sure it's done well and as quickly as possible, so a house doesn't stay unprotected for longer than necessary. Once they finally finished earlier projects and started working on our roof, they were 100% on task from start to finish. They are a small company and ours was a complex, 4000+ square foot roof that required ordering special materials along the way, so it took about a month to complete the job with 3 guys working 40 hours per week. However, I really appreciated the way they always started promptly on time each day and worked closely with my wife and I throughout the entire process to make sure work was being done exactly as we (and the City's historic rules) needed it done. Pete and his crew were friendly and very accommodating of special requests related to the historic peculiarities of our house, skylights, neighbor's concerns about parking, etc. Many parts of the roof required creative, on-the-fly problem solving, due to the non-standard construction of our 1800's house. Genaro, especially, was great at innovative problem solving and did beautiful work, but everyone on the team was super dedicated, hard working, and skilled. We have already had one heavy downpour since the new roof went on, and not a single drop got through! I can confidently recommend Positive Results Roofing if you are looking for a small, personable company that is licensed and bonded and does quality roof replacements or repairs for a reasonable price."

"I would strongly caution anyone considering this roofing company. We had our roof redone in July 2025, and by February we experienced water damage inside our home. After inspection, the issue appeared to be related to poorly installed flashing around a vent. Instead of taking accountability or even seriously investigating the workmanship, the company quickly dismissed the problem and claimed it was caused by an animal, therefore not covered under their warranty. This was disappointing, especially given how soon the issue occurred after a full roof replacement. A reputable company should stand behind their work and be willing to thoroughly assess potential installation issues rather than deflect responsibility. The lack of accountability and unwillingness to help resolve the damage left us dealing with repairs on our own. Based on our experience, I would recommend looking elsewhere if you want a company that stands by the quality of their work and provides reliable customer service."

FAQs for asphalt shingle roofing installation and replacement projects in Gilroy, 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.
