Typical Greater Boston range for this kind of work, from regional averages — not a quote from WJZ Construction. Use it to sanity-check bids, then get the real number in writing.
A square is 100 sq ft of roof surface — bigger than the floor plan because of pitch and overhangs.

Typical roofing project around $13,800
WJZ Construction does roofing, siding, porch and deck work on homes. Its home improvement contractor licence, 216647, is active on the state registry. In a 2026 review, a customer with rot on a front porch and mudroom said William and his crew repaired and replaced the rotten wood, then installed vinyl siding on the entire porch, all in one day, and cleaned up every bit of the construction materials. A 2026 reroofing customer said William and his team were professional, efficient and detail-oriented, and that the work was completed on schedule. Another 2026 review thanks them for window replacements. In a 2025 review, a customer said William, Victor and the entire crew removed the old cedar wood shingles, repaired the wood rot, replaced it with new siding and installed new gutters with leaf protection, getting the entire job done in just a few weeks. A 2025 review of a 1st and 2nd floor porch replacement describes a difficult project with weather delays and plan adjustments, with William always available onsite and by phone. In a 2024 review, a customer said that when water started dripping from the top of the kitchen windows, William identified a roofing issue that got fixed, as well as additional flashing around the windows, and got in contact several times afterwards. A different 2024 review describes a chimney reflash and repoint that uncovered more damage; that customer said the whole repair, from contacting to fixed, took less than a week. A 2023 one-star review said they did not wrap the roof properly, did not come back for a few weeks, and it leaked into the house and ceiling, destroying the carpet; that reviewer also said they left the job incomplete, not hanging fixtures back up.
great service .more than I expected and the crew are very friendly.thank you William
Cut me off on a highway on 495 south this morning pretty badly. Driving all above the speed limit.
Thank you William you did great job👍👍
We could not be more thrilled with our renovation from WJZ Construction! We had some rot on our front porch/mudroom and had been told that it would be a total demo and rebuilding project. William and his crew were able to repair and replace the rotten wood and then install vinyl siding on the entire porch. This was all done in one day! Our house looks amazing and we are so happy that it is protected from the weather now. WJZ also added special touches that made the finished project feel polished. William is a pleasure to work with and a true professional who takes pride in his business. The entire crew is so hard-working and efficient and they cleaned up every bit of the construction materials. We will definitely be using this company for future projects and have no reservations about recommending it to all of our family and friends.
Thanks to William and his crew for give my home a face-lift. It was well over due. They went above and beyond the scope of work and pricing was very good. I am very pleased with the outcome. They started early and stayed late. I can really appreciate that being in the construction field myself. Many of my neighbors has hired them to do work on their house. That's saying a lot. I would definitely work with WJZ again.
