Costa Construction Company is a roofing company whose owner, Valdizar, works directly with his crew, according to a recent customer who hired it twice for two different roof issues. Its Connecticut home improvement contractor registration, HIC.0664786, is active on the state registry, held by Costa Construction Company LLC. A recent customer said Valdizar and his crew installed a new roof and two skylights and cleaned up the property. A recent reviewer said Valdizar, one of the owners, was on site daily during a total roof replacement with 7 skylights. A recent customer said Valdezar and his crew completely rebuilt a chimney, with pointing around the brick line, new lead flashing and a new cement ridge cap. A recent customer with a leak in a sunroom roof said Val arrived the same day to give an estimate and the work was done that same week. The work goes beyond roofs. A 2026 customer said Costa Construction replaced old gutters and recommended moving some downspouts, which addressed water collection issues. A 2026 customer said Valdizar cleaned the gutters with a before and after picture of each one, then later pressure washed the house and the mildew was gone. A 2026 customer dealing with ice damming said Valdizar came the next day and eliminated it. A 2025 customer said the company replaced an old roof, repaired rotted trim and siding, painted the exterior of the house and replaced the porch deck boards. A 2025 customer said the company offered copper flashing instead of lead around the chimneys at no additional charge. A 2026 Reddit commenter recommended the company, citing fair prices and easy communication. A 2023 customer said the roof job was good but they never received an invoice or receipt after requesting it multiple times, and a promised visit to quote another job did not happen.
“I highly recommend Costa Construction Company LLC. They are very professional, reliable, and do great quality work.”
Amazing job and price. They were able to come and fix the leak in my chimney very quickly. Would recommend and use this company for future projects.
I had the team recently at my house. Excellent service from start to finish! The roofing company arrived on time, was professional, and did an outstanding job. My ceiling was leaking. I did not know what to do. They came on time. The team worked efficiently and made sure everything was done right. We are very happy with the results and would highly recommend them to anyone needing roofing services!
Valdezar and his crew they did an amazing job completely rebuilding my Chimney. Performed pointing all around the brick line. Removed the old flashing, replaced with new material. Removed the old shingles and replaced it with new Lead Flashing. Installed new plywood as needed. Installed ice and water to prevent any water damage going into the attic. Replaced the shingles on the ridge line, due to prior roof work not done correctly. Installed new cement ridge cap. Cleaned up after the work was done on all areas. Including the front and back lawn. I highly recommend Valdezar and his company to friends and family. He is very reasonable with his pricing and backed up with his Guarantee labor. They take great pride on their workmanship.
