"Follow up to earlier review -JJP Contracting Jose and Brian are running a top tier business. I'm going to be totally honest with the people of Angi- We hired this team to perform a siding job and it originally didn't go well. They pulled down the pre-existing wood shingle siding that was rotted and installed new Siding on the home. When the siding first went up there was a defect that we all couldn't understand. We thought that it wasn't okay to leave it up but tried to see if the warmer weather would cause it to unbuckle. JJP stood by their words even months after the siding had been installed and came back to make the necessary fixes. I appreciate this more than the team knows because too often contractors are not true to what they say. This team is running an honest business that I can truthfully say that I trust. I look forward to discussing further projects with their group."

"Roofing its something no home owner ever wants to do, but most have to go through. I won't even lie I wasn't even planning on getting a new roof, but Dale Knocked on my door and thats where the process started. My roof did go through insurance & aside from signing paper work/paying my deductible A1 handled everything. Obviously specific details from the insurance goes to you and then given to A1. Its not a short process and there is paperwork you have to sign, but all In all it did take me about 4 to 5 months where the process was started to roof replacement. Dale handled interactions with showing my the conditions of my roof and how to go about getting it put through the insurance. The only hiccup was that I have solar panels and I did feel like they where taken down to early (almost 5 months off), but I made my concerns known and one of the Managers called me and credited me $500 bucks (100 per month) that the panels where off. They did tell me setbacks in productions and things happen, but made me happy by giving me this credit. Didn't fight me on it, and didn't make me feel like I was just an insurance check on the other end. You can trust A1 home improvement with your home. I would like to thank Dale for his work & all the others that helped me throughout one of the most stressful process there can be for a house."

"We couldn’t be happier with our recent bathroom renovation! Carlos was fantastic to work with—he made helpful suggestions throughout the process, including where to purchase materials and creative ways to add extra storage in our small space. The team took the project down to the studs, replaced and relocated plumbing and electrical, and did a meticulous job with the tiling. The results exceeded our expectations—I’m absolutely obsessed with our new bathroom! Carlos and his team were professional, attentive, and a pleasure to work with. We’ll definitely be hiring them for our next renovation."

"Excellent - Tito was extremely responsive and his team did excellent work. I shopped around and got multiple quotes, and his was the lowest. More importantly, he had done work on a number of my neighbors’ homes and came highly recommended. His team was very responsive and got the work done on a short time frame which was great because I needed much of the work done before I moved in to my new home. My floors and skylights look great and I have full confidence in his work. One thing which I really liked is the fact that he is constantly in communication, is always available, and is local.

"I couldn’t be more impressed with Strong Hammer Contracting! From the moment I contacted them, their team was professional, prompt, and clearly experienced. They arrived right on schedule and handled my gutter cleaning with meticulous care—thoroughly clearing out debris and even checking for minor issues I wouldn't have noticed myself. What really stood out was their attention to detail and respect for my property—they left everything spotless, and my gutters have never flowed better. It’s such a relief knowing I can count on a company that takes real pride in their work. I’ll definitely be using their services again and recommending them to everyone I know!"

Roofing questions, answered by experts

Unfortunately, there’s no definitive answer to this question, but the wind rating of your shingles will give you a good idea of what wind speeds can damage your roof. If you’re concerned about damage, inspect your roof following windy conditions to look for signs of wind damage to your shingles. When in doubt, consider hiring a professional who fixes roofs to carry out an expert inspection. Remember that hurricanes, tropical storms, and tornadoes are likely to cause the most damage, but even severe thunderstorms can bring winds that compromise your roofing system.

Building an A-frame roof falls under the category of constructing a steep roof. While its structure is relatively simple, its height and requirements for more materials than a shallow roof design can increase its cost significantly. Expect prices for building an A-frame roof to hover around average to slightly above average.

Yes, hail damage to your roof can definitely cause water leaks in your roof. This is because hailstones can break, chip, crack, or split shingles of all types, exposing underlayment. This underlayment doesn’t offer as much protection against water, so when it becomes compromised, water can penetrate and leak deeper into your home.

If your roof has a vapor barrier, you will need approximately one square foot of roof vent for every 300 square feet of ceiling space. If there is no vapor barrier, the roof should have one square foot of roof vent for every 150 square feet of ceiling space. If you are not comfortable making this determination, a local roofing professional can help.

When choosing a roofer to install a green roof, look for someone with experience who specializes in green roofs. Rather than looking for a standard roofing contractor, you'll want to find a company that specifically offers green roofs. That company will have people on staff, such as a landscape architect, who understand the types of plants that thrive on rooftops.
