- They followed up diligently with my insurance company and persevered through many back-and-forth.
- Ernesto and Jonatan were always responsive to our questions and ensured we knew what was happening each step of the way.
- Their professionalism and follow-through made a big difference.
- The job was done efficiently in the time they gave us.
- They handled all the coordination of working with our homeowners insurance.
- One point of disappointment was that the job was sub-contracted out, and the subcontractors didn’t seem to uphold the same standards I expected from Alfa Design and Build.

We had ALFA do a very complex back deck on our new-build NDI house; it was very high off the ground, and needed some additional design considerations. Ernesto worked through the entire design process with us with very quick responses, and close follow-up, especially with respect to the Fairfax County permitting process.
Most important, when we had a very minor issue this summer (boards pulling up, out of line with the others, likely due to heat), Ernesto got his crew to come inspect and address the issue the same week. Very thorough follow-through and excellent service - even after the job was done!

Alfa initially reached out to me after a hail storm. They explained what they could do very clearly and laid out a plan. They followed up diligently with my insurance company and persevered through many back-and-forth. Once the work was approved, they put an excellent team together and explained what they would do and how long it would take. They completed the work on time and made sure I was 100% satisfied. Throughout the process and they were very communicative and friendly. I highly recommend them.

After reading the positive comments from their previous customers and upon meeting Jonatan for the first time, I knew I wanted Alpha to rebuild my front porch. Jonatan explained to me that pavers would work the best on top of my existing brick porch. I met with a few other contractor representatives and Jonatan was by far the most knowledgeable, , most friendly, and most sincere rep. He was the only one that came back with an estimate when he said he would. In fact, he always responded to my questions or concerns almost immediately! Once I signed the contract, Jonatan said they could start the work within the week and they showed up when they said they would. I was pleasantly surprised that Jonatan’s crew started early in the day and didn’t leave until evening. Except for some touch up work, they had finished the job! I’m totally ecstatic about the beautiful job they did. And, so many of my neighbors have complimented Alpha’s workmanship too! Thanks Jonatan!

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.

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.
