"My family had a good experience with Gil from Sharp Remodeling. He was recommended by a close family friend, Ofelia Galvez, and after much consideration, we went with him. Our insurance wasn't covering any roof repairs, but because of the recent rains and continuous water damage inside the house, it was a matter of urgency. Gil's crew was polite and friendly, clean and efficient. Amazingly, they finished all the work in about a week. This included replacing rotten wood and broken tiles, and completely upgrading the underlayment with Boral TileSeal, which is guaranteed for 30 years. Our roof passed city inspection, and Sharp Remodeling guided us through that process, as well as getting the initial permit from the city. All in all, I find that Gil made it quick and painless for us. During a time when it seemed that everyone was extremely busy due to the unexpected rains, Gil made sure that our needs were met. His price was even better than what our neighbor paid for their re-roofing project. So far, it's rained a couple more times, but the leaking seems to have stopped. For that, we thank Gil and his team."

"I obtained 3 estimates to replace multiple broken and dislodged tiles on my roof and fix the underlying material. 1 general contractor and 1 other roofing company. T&G came in below the other roofing company by a considerable amount and only slightly above the GC. They provided very clear estimate documents and despite warning me of possible overages based on things they might discover after starting the repair came in exactly at their estimate. They were on-time, finished in the time estimated, were very clean and professional. I recommended them to several other folks who came by and asked since seeing them on my roof."

"I needed a new roof to sell my home and reached out to several roofing companies. Top Pros Construction responded the very next day with an amazing quote and great product options. They removed the old roof and installed the new one on the same day, and it looks fantastic. Just a week later, my house sold, and the buyers were thrilled with the new roof. I highly recommend Top Pros Construction for their excellent service and quality work!"

"I was looking into replacing my 20+ yrs tile roof to the Tesla solar roof but after months of waiting (I pre-ordered the solar roof and it was stuck at the design phase), Tesla told me that they no longer serve my area and refunded me the money. As I was looking for an alternative, I came across GAF's solar shingles and I was very interested in them. Guardian Roofs is GAF's certified installer in SoCal area. Larry from Guardian Roofs reached out to me within a day after I filled out the "Request for a Quote" form on GAF's website. Told me about their company and we chatted about my needs for the new roof and solar system. Within the next few days, he sent me a proposal, explained every single detail to me carefully and patiently answered all of my questions and concerns. He truly enjoy working with Larry because he would find out the answers for any questions he wasn't able to answer on the call and actually called me back and explained them to me thoroughly. I called/emailed six roofing companies/contractors, only four responded within the first week with a quote. The quote from Guardian Roofs was the second lowest (cheaper than Tesla's solar roof). The other three quotes were traditional solar panels and reroof using the existing tiles. I quickly decided to go Guardian Roof's quote not only it's much cheaper than Tesla's solar roof, but their panels also looked much nicer than the traditional ones. My only concern was that without the space between the rack and roof, how would the heat generated by the panels being released? I asked Larry this question and he explained to me but I didn't quite understand, so I asked the owner, Justin, the same question during the installation and he explained to me by showing me the actual products. Turned out the combination of the underlaying sheet, GAF's Timberline Shingles and the actual panels were playing a big part in handling the heat. The installation took a week to complete. I'm very pleased that the owner himself actually came out a couple of days and climbed on the roof to make sure everything was done correctly. He was also there to answer all of my questions about the job. Additionally, GAF sent a technician from the San Jose headquarter to oversee the installation of the panels. Not the mention William (the lead installer from Guardian Roofs) and his crew did a great job cleaning up the area after the job was completed."

"After getting several quotes and meeting with multiple contractors for our roofing, we decided on GT Remodeling. We could not be happier with their services. They were super organized from the start! They even helped us choose the best options for our needs and budget. Thank you so much for all your hard work and for listening to our concerns. We decided to hire Gady because of the customer service and the final product. Our new roof looks amazing and we are confident it will last for many years! 5 stars all the way!"

"Working with Joe and team at Shulman Roofing was a great experience!  I have dealt with many contractors, and my experience with this team was by far the best I have experienced.  Joe showed up very prepared for the initial estimate.  Brought samples and literature for all the products that he installed.  Helped with selection of materials and explained in detail how the process would work.  When I asked for multiple samples to lay on the roof, they showed up on my doorstep the next day.  Entire project lasted 5 days.  First 3 days were spent repairing damage.  Repairs were very complex, including multiple rafter tails and T&G sheathing.  Any issues I pointed out were repaired immediately.  Repairs ended up flawless.  Shingle and flat roof took about 2.5 days.  All flashing, channels and vents look excellent.  It is easy to see that Joe's team has spent many years in the industry.  All materials were cleaned up and house looked good as new at completion.  I would HIGHLY recommend that you consider Joe for your project.  Throughout the project he was very responsive to all questions, and I even got daily updates with pictures of any repair work that was being done. <br />"

"I called roof repair specialist, on a Saturday afternoon, after we had the heavy rains in Pasadena. I was greeted by Chris and  he helped me set up a appointment for a inspector to come out and check out my leaks.  <br /> We had 3 separate leaks, one of which was unsuccessfully attempted to be repaired by another roofer in the past.  <br /> Peter came out and identified the 3 leaks right away and gave me a estimate on the spot. I decided to go with them as he really knew what he was talking about. He showed me pictures and gave me a run down of exactly what needs to be done.  <br /> A few days later there tech stopped by and completed the repairs on the roof. I was unable to be home but they assured me that was not a problem. They even sent me before and after pictures to show the work that was done.  <br /> I am completely satisfied with the work that was done. They really did everything possible to make my life just a little bit easier.  <br /> <br /> <br />"

FAQs for roofing installation & roof repair projects in Ontario, CA

An average Cape Cod roof-raising project requires approximately two to three months from start to finish. The timeline depends on several variables, including weather conditions, contractor availability, material delivery schedules, and the specific complexity of your home's structure. The process involves multiple phases, including demolition, framing, roofing, window installation, and interior finishing. Working with an experienced contractor who provides a detailed timeline can help set realistic expectations for the project duration.

While most Cape Cod homes can accommodate roof-raising modifications, each house requires individual structural assessment. Older homes may need foundation reinforcement or wall strengthening before supporting additional weight. Factors like the existing roof framing system, load-bearing wall placement, and overall structural integrity all influence feasibility. A qualified structural engineer should evaluate your specific property before proceeding with design plans. Additionally, local zoning ordinances may restrict maximum building height or architectural modifications in certain neighborhoods.

Temporary relocation is highly recommended during a Cape Cod roof raising project. The construction process involves removing portions of your existing roof, exposing interior spaces to potential weather damage, and creating significant noise and dust. Most homeowners find temporary accommodations for the two to three-month construction period, with relocation costs ranging from $2,000 to $6,000, depending on your housing choices. If staying with family or friends isn't possible, budget for short-term rental or extended-stay hotel expenses as part of your overall project cost.

Consider roof raising when you experience severely limited headroom throughout the second floor, find yourself constantly stooping under sloped ceilings, or have minimal usable floor space due to low ceiling heights. Other indicators include inadequate natural light, poor ventilation, and difficulty accommodating standard furniture in upstairs rooms. Simple renovations can improve an attic's appearance, but cannot create additional headroom without structural modifications. A complete roof-raising project makes more sense than cosmetic renovations if you're seeking genuine second-floor living space rather than just storage improvements.

Begin your search by seeking contractors with specific experience in Cape Cod structural modifications and dormer additions. Request detailed portfolios showing similar completed projects and ask for references from previous clients with comparable work. Verify that potential contractors hold appropriate licenses and insurance coverage and understand local building codes relevant to roof raising. Interview multiple candidates, comparing price quotes and their communication style, project approach, and proposed timeline. The ideal contractor should demonstrate a thorough understanding of Cape Cod architectural characteristics and structural requirements.
