I requested an estimate and they came right out. They quoted me the price and once I agreed they quickly scheduled my work. I was getting a full roof replacement as the roof hasn't been replaced in over 20 years. During scheduling they walked me through the process. they told me which day the materials would be delivered and which day the work would start which was the next day. The crew showed up and laid tarps around the entire home. I had some rotten wood on the roof and the price to fix that was extremely reasonable and they had what they needed on hand so there was no delay. Once done they left the area cleaner than when they arrived blowing off all the side walks and porches which I had not gotten two. I would definitely recommend Darvish to family and friends.
Do not use this company to put your roof on, I have been in my house for 5 years and because they don't know how to properly install ridge vents im having to pay 1000 dollars to replace them. Leaks all over the place and wanted 200 dollars to just come look at it, this place is a joke. Just got a response months later saying it was the materials and not their work. I had another reputable company look at my roof when the leaks happened and said whoever put the roof on did a laughable job
From the first contact with company from proposal to final installation I was treated in a professional manner and they were always responsive to my concerns. If a date slipped due to the weather I was immediately informed. The work crew was there on time, kept the work area cleaned and did a great overall job. The finished roof was exceptional, I have gotten numerous comments from neighbors and passer byers, 3 have asked for the companies phone number. I was especially pleased by the prompt follow up company inspector who reviewed the final job immediately after it was finished. Overall I am extremely pleased with my experience with Darvish Construction and I would highly recommend them to my neighbors and friends.

The average roof replacement cost for a residential home typically ranges from $7,000 to $15,000, depending on factors such as roof size, chosen materials, roof pitch, and labor rates in your area. Premium materials or complex designs may increase the price.
The cost to replace the roof of a commercial building typically ranges from $5 to $12 per square foot, depending on several factors such as roof size, material, labor rates, building type, and local code requirements.
Several factors influence roof repair cost, including the extent of the damage, roof accessibility, material type, labor costs, and whether it’s a general repair or an emergency fix. Minor repairs can start around $150–$400, while major repairs may exceed $1,500.
Roof leak repair cost generally ranges from $300 to $800, depending on the size and location of the leak, the materials required, and labor intensity. Complex leaks involving structural repairs or interior damage will cost more.

Mobile home roof replacement cost typically ranges from $3,000 to $8,000, making it generally more affordable than traditional home roof replacements, due to smaller size and simpler structure.
It's not necessary to stay home during roof replacement. Roofing work is noisy and can cause vibrations inside the house, which might be uncomfortable. Most homeowners choose to leave during major parts of the project, but our team ensures safety and keeps you updated, whether you're home or not.
The timeline for a roof replacement typically ranges from one to three days, depending on the size and complexity of the roof, weather conditions, and material type. Larger or more intricate roofs may take a bit longer, but we always aim for efficient, timely completion.
To hire a roofing contractor, start by researching local companies with good reviews and proper licensing. Request quotes from multiple contractors, verify their insurance and certifications, and ask for references. Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.
Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.
When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.
Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
