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!"

Structural Engineering questions, answered by experts

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation—which are built into a monolithic slab—sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.

Most structural engineers offer free quotes, regardless of the size of the job. For simple inspections when buying or selling a home, engineers typically charge a flat fee that may be based solely on your home’s foundation type and square footage. For larger projects, like new construction and major home renovations, an engineer will either perform an analysis of your project and site and provide you with a formal estimate, or they will do a more in-depth assessment and in-person site inspection before coming up with a per-hour or per-project cost estimate. In most cases, the estimate is free.

Yes, a one-story house can have a load-bearing wall. The load-bearing walls in a single-story home are usually the exterior walls. If the house has a basement with exposed walls, the arrangement of the beams can help indicate what walls are load-bearing.

A structural engineer’s report includes a professional assessment of a property’s foundation condition, structural elements like roof trusses and floor joists, and the skeleton of the home, including studs, beams, and rafters. It will also usually include an assessment of drainage on the property and any potential issues that could arise from environmental conditions, like extreme weather in the area and even tree placement.
