Building projects are rarely stress free. They can be more involved and complex than expected, often leading to confusion and frustration. We know. We've been there ourselves. We have houses and families. We've built additions for in-law apartments and removed bearing walls to make our kitchens bigger. We've had water in our basements, built and re-built decks, repaired retaining walls and and renovated old properties. We know what building projects can be like because we've done them too. Our goal is to provide our clients with step by step, start to finish engineering guidance that results in peace of mind and confidence in a job done right. We take great pride and care in working to understand the needs and expectations of our individual clients, and bringing our experience and expertise to bear on their specific, nuanced needs. Our reputation is based on service, safety and quality, regardless of how large or small the job. Call us today - we're here to help!

"Their service was excellent. They came out to our western mass region from the Boston area- unusual .....we usually get the cold shoulder from Boston. Even several local engineers turned us down. The structure is an 1885 church and a structural report was required from the local building department. They were very professional, quoted a price, made the trip and wrote up an encouraging and positive report. We have been fundraising since then to continue the restoration. Thank you Veritas!"

Flynn Roofing Co. was established in 1997 by Stephen Flynn. We are a small family-operated company that specializes in residential and commercial roofing, both asphalt shingles and rubber roofing. Some of our non-residential customers have included a nursing home, motel, town hall building, condo associations, a Mason lodge, and multiple office buildings. Our goal is to provide our customers with outstanding customer service and complete satisfaction. We pledge to return every phone call in a timely manner and address every question completely. We have an extensive listing of references showing our satisfied customers. We are not satisfied with your job until you are satisfied. We serve the Greater Boston area, the South Shore and Metro West. We are fully insured, including workers compensation and we use absolutely NO subcontractors, which is almost unheard of in this industry. The company you hire to do your job will be the company that arrives at your home. We pledge to install your roof as quickly as possible, while maintaining our strict quality standards. We work on one roof at a time and will be at your home daily (weather permitting) until your roof is completed. We work in an efficient and orderly manner, leaving your yard as we found it at the start of the job (some customers have said even better!). Flynn Roofing Co. is a Certainteed Select Shingle Roofer company, enabling us to offer our customers who choose Certainteed shingles a five-star warranty. This warranty includes a 15 or 20 year workmanship guarantee, along with the standard materials warranty. We purchase this warranty for ALL of our customers. We are also a GAF Authorized Installer. We are a proud member of the Northeast Roofing Contractors Association and the Better Business Bureau. We have had 0 complaints reported to the Better Business Bureau since we joined on 1/4/05.

"What I thought was going to be a painful process turned into a pleasant experience. Mr. Flynn was very timely in giving me a quote, supplying information about the materials, paperwork such as insurance certificate , and not subbing out the job. Mr. Flynn's crew was here at 7:50 AM. Stopped for lunch at 11:30 returned to work promptly at 12:30 and was finished with the job by 3. They were all very professional and courteous. The clean up was impeccable. Mr. Flynn and his crew know how to run a business. Kudos to Robyn too for all her help. Great Company!"

"DO NOT HIRE. If you're looking for a misogynist old man to tell you he did his job when he didn't hire Cowen Associates. The worst customer service I have ever experienced. Fred, the owner refused to give me measurements that he claims were written in his drawing and then called me to tell me it's not his job to give me the measurements. He charged me $200 per hour to then tell me I shouldn't be the general contractor on my own job and that I don't know anything."

Structural Engineering questions, answered by experts

Yes, all states require structural engineers to carry the proper license, with specifics determined by each state. You can use Angi’s state licensing tool to confirm that the structural engineer you’re considering holds the required licensing to tackle your job. Hiring an unlicensed structural engineer will not only cause issues with permits but it could also lead to an unsafe building. The cost of a professional, licensed, and experienced engineer is well worth the investment.

Costs depend on unit complexity, labor, wall mounting needs, and additional accessories like floating shelves.

Yes, ceiling joists are typically load-bearing. However, their primary function is to support the weight of the ceiling and loads applied to it, like lighting fixtures and ceiling fans. They can also help support the roof, especially if they’re part of truss systems. Remember, the load-bearing capacity of ceiling joists depends on the material, size, and space between them. 

The process involves initial consultation, concept development, detailed planning, regulatory approvals, and integration of contractor work for project execution.
