"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."

Additional DBA - King Quality Construction. King Quality’s seven-part, patented roofing system controls moisture through the ventilation system and prolongs the life of the roof, along with a leak proof guarantee quality shingles, distinctive ridge cap shingles, and effective attic and soffit ventilation.

"They installed our roof in the pouring down rain. Asked multiple times for them to stop, they did not. Paid for the 50 year warranty. Our roof has flaws now that require repairs especially with the winter months approaching. I reached out on Facebook and within seconds my question was deleted and I was blocked. My wife reached out to Jeff Brett and received a response to now find out that he too has blocked her. This company will not admit to their mistakes nor take the appropriate action to correct them. Call and either they don't answer or we get the run around. On top of all of this they damaged hundreds if not a few thousand worth of my brand new flashing and vinyl siding. This company is not worth their word nor contracts considering they are actively breaking the agreement in which we signed for. GO ANYWHERE ELSE!"

"We reached out to Brother's as a former customer from 40 years ago. They came to my home, spent over an hour with us to listen to our needs, provide us with samples, and discuss options. Brothers resided our new home, replaced the roof, gutters, soffits, flashing of the chimney, replaced a new window, and pitched part of one of our chimney's. The work was impeccable. The owner was available for questions, the foreman was approachable, the workers kept the property neat, and our home looks brand new on the exterior. Brothers Alumnium didn't disappoint 40 years ago, and they didn't disappoint now. Highly recommend. 5 Stars!!!"

"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!"

"I called for a repair to my daughter's roof. The room with the wet sheetrock has a cathedral ceiling with no attic access to determine the source of the leak. Steve inspected the roof section and suggested that the wetness was due to condensation. Vents were installed and small section of roof was replaced at a very reasonable cost. Steve always responded to calls and follow-up questions promptly, Very competent and obliging. A pleasure to work with,"

Roofing questions, answered by experts

If a roof is not vented, trapped air and moisture have nowhere to go and will cause moisture to build up in the attic. When moisture builds up, it can cause mold and mildew, leaks, and rot. It will make the space hot and stuffy, which can result in higher energy bills as the HVAC system works overtime to regulate the temperature.

Yes, chimney flashing is an important element in the complex system that is your roof. Chimneys (and anything else that goes through your roof) provide a great opportunity for water damage. Good flashing prevents a lot of potential damage. 

After you take steps to determine when your roof was last replaced, you may realize you need a new one. Hiring a roofing contractor you can trust involves asking for references and examples of past work. Verify any qualifications the roofer provides. Ask about the expected time to complete the work and about putting guarantees in writing.

The cost to replace a roof averages around $9,200, and most people pay between $6,000 and $15,000. The size of your roof plays a major role in the total cost, but the most significant factor is whether you need new shingles placed over your old roof or a full replacement. The former is possible until you have three layers of roofing on your home, and it’s more affordable. A full replacement involves ripping off old layers of shingles, sometimes repairing the sheathing, and then laying down a new roof, which is the most expensive project.

Yes, many contractors offer warranties for their work. Confirm terms before hiring.
