"Contracted Federal Building and Roofing with Richard and his team after Listening to Richard's suggestions during the estimate. Had bad water damage to many Rafter Tails as well as a severe leak in the garage, Had several Contractors out for estimates some wanting to go a much more expensive route to repair the damaged wood on the Rafters as well as suggesting a complete Torch down on the entire roof which was not needed, which came with a less than desirable Warranty along with higher costs. Richard gave me peace of mind with his knowledge and suggestions which in turn provided a much longer Warranty and cheaper more effective route to repairing the damaged Rafter tails,all at a very reasonable price compared to other estimates. Any Contractor should have been able to provide me with these suggestions and alternatives but failed to do so. Richard and his team were Professional, polite,cleaned up thoroughly each and every day and completed the job on time as scheduled."

"Got quotes and talked to 3 other roofers. 3rd Generation Roofing gave me the best pricing, great costomer service and followup, and their crew was efficient and clean. I would, and already have, recommended 3rd Generation Roofing to others in need of a new roof. Altogether a good project experience."

"They were kind and efficient. I had to be diligent and push them to do a water test of the roof or else they would have diagnosed it with the wrong issue. But other than that, they were able to perform the work and solve the issue. It ended up needing a flashing maintenance rather than to re-do a whole portion of my roof (big difference... $1,500 vs. $4,500)"

Roofing FAQs, answered by experts

While it’s technically possible to repoint a chimney without scaffolding, it’s not recommended, especially for taller chimneys. Scaffolding provides a stable platform that allows for safer and more precise work. Without it, you might find yourself in a risky situation, and the quality of the repointing could suffer.

The most obvious and severe sign of a roof leak is the presence of wet spots on your ceilings, specifically on the top floor of your home. You can also identify a roof leak from your attic if you see sagging insulation or if you notice mold growth or water stains on the rafters or the underside of the roof deck. From the street, look for cracked or missing shingles, moss growth, and shingles that are curling upward, all of which can suggest a leak.

No, there’s no specific building code that requires a roof overhang. However, installing your roof with the standard 2-inch overhang is good practice, as it helps direct runoff away from your fascia boards and roof decking and into your gutters. Some overhang is especially important in areas that see heavy rainfall and snowfall, as the risk of water getting under the roofing material and causing water damage is much higher.

Roof leaks develop quickly and can cause serious damage to your house and in extreme cases, quite nearly ruin it. Roof leaks have been known to affect even the foundations of a home, so taking care of any issues as soon as they pop up—or even before—is of the utmost importance.

If you’re building the roof trusses yourself, which isn’t recommended, it will be more affordable than buying pre-built trusses. Trusses cost more because they use the same amount of material, but you’ll also be paying for the labor, as well as the delivery to your home. However, if you’re having a contractor build the roof for you, then trusses will be less expensive, as the labor costs to build roof framing on-site will cost more.
