"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

Properly installed chimney flashing can last anywhere from 15 to 50 years. However, flashing generally only needs to be replaced when it is damaged, corroded, or no longer creates a watertight seal. Several factors influence its longevity, including the material type, quality of installation, and local climate. For example, copper flashing tends to last longer than galvanized steel. Large storms and extreme weather can also damage flashing, potentially requiring earlier replacement. To ensure its longevity, it is recommended to have your chimney and roof inspected annually. A professional can assess the flashing's condition and recommend any necessary repairs.

A square of shingles covers 100 square feet and usually ranges from 150 to 240 pounds. It all depends on the material and type of shingle.

You shouldn’t put a new roof underlayment over an old one for a few reasons. Old felt must be removed in order to assess the condition of your roof decking, such as rotting wood or other structural issues. Also, if your roofer doesn't install a fresh layer of felt as is required by shingle manufacturers, your warranty may be voided. Finally, old underlayment removal is often included in the cost of roof repair or replacement, so there's no real benefit to leaving it on before installing a new layer.

Thatched roofs are expensive for two main reasons: high labor costs and low supply of available roofers. The labor is more intensive for a thatched roof than other roof materials, so your contractor will work longer and charge more for the installation. There are also few professionals with the specialized skills and experience to install thatched roofs. Since the supply of available professionals is low, the cost of compensation is high.

You can negotiate roofing payment terms with a contractor, but if you’re working with a reliable, trustworthy roofing contractor, the quote they gave you is probably fair. It’s often not worth haggling over the cost of the job unless you feel it is particularly unfair. If you do, get quotes from other roofing companies to compare prices.
