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!"

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.

Structural Engineering questions, answered by experts

Signs of structural damage include foundation cracks, roof leaks, bouncy floors, crumbling concrete, and cracked or leaning chimneys. Structural damage can make itself apparent in various ways, and sometimes, there may not be obvious signs. Inspect your foundation and roof annually to stay ahead of potentially serious structural problems. 

A split-level home is one that has several staggered floors connected by short staircases, while a split floor plan separates the primary bedroom from the rest of the bedrooms. Split floor plans are most often found in single-story homes, while split-level homes are always at least two stories.

Structural engineers draw structural plans, which include detailed drawings of the structural components of a home only. Complete house plans will require additional work from an architect or draftsperson, whose drawings will take the structural drawings into account. They’ll also include more details about the finishing materials and layout of a home, including everything from roofing and flooring materials to the position of furniture, light fixtures, switches, and plumbing fixtures.

Structural engineers typically charge between $100 and $250 per hour, but many jobs won’t be based on a per-hour fee. Instead, the structural engineer will offer a flat rate for the inspection and structural calculations. The flat rate for a structural engineer costs an average of around $550, but you could see prices ranging from $300 to $800, depending on the complexity of your project and how easy it is to access certain parts of your home for the inspection.

You need to hire a structural engineer when building or modifying any component with a structural load in your home. Common situations where you would need a structural engineer include home inspections when buying or selling a home, investigating possible issues with your foundation, beams, load-bearing walls, or chimneys, breaking ground on a new home or structure on your property, and renovating an old part of your home that could threaten any structural integrity. Home additions and bump-outs also require an engineer.
