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.

"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!"

"Joe and his team did a superb job of renovating my bathroom in a 1929 vintage building in Cambridge, MA. The final result is modern and highly functional while looking beautiful in an older building. Joe helped me pick materials and finishes that I would not have discovered on my own. He and his team were respectful of my home making sure that there was as little disruption as possible and wore masks and maintained distance at all times. When I miscommunicated with a house cleaner near the end of the project, Joe did much of the cleaning himself. Above and beyond. Last but not least, the work was finished on time. Amazing.

Structural Engineering questions, answered by experts

In many areas, advice from a structural engineer or an architect will be required by your building department before you can remove a wall, but even if it’s not necessary, it’s a good idea. Accidentally removing a load-bearing wall—even if a general contractor advises that it’s safe—can cause major structural damage, putting you and your family at risk and potentially costing thousands or tens of thousands of dollars in property damage.

You should pick steel for your new support beam for a few reasons. While steel is more expensive than other materials, such as laminated veneer lumber or glulam, it offers the following benefits:

  • Fire-resistant

  • Unaffected by pests

  • Longer-lasting

  • Stronger against water damage (when galvanized against rust)

The standard thickness for an LVL beam is between 1.75 inches and 7 inches. However, you can order LVL beams in non-standard sizes as well. When you work with a contractor, they can source beams that are the appropriate size for your project for you after assessing your blueprints.

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 should avoid drilling or cutting into load-bearing beams because removing material will weaken it and increase the risk of structural damage or even collapse. If you do need to drill into a load-bearing beam, speak with a structural engineer first to discuss where it’s safest to drill and the width and depth of the bit that’s safe to use.
