"Our house was re-roofed in July 2016 by George J Keller & Sons. We had estimates from 7 roofing companies and felt most comfortable with Keller. We felt Keller was the most honest because they didn't try to low ball the work. Our roof had been leaking on and off so my husband walked the roof and knew that we had some warped and/or soft sheathing. The other companies that came out told us only 3 to 4 sheaths would require replacement but we knew there were many more. We didn't want to select a roofer who wasn't honest from the beginning, Our sales person was Mike Koty and we liked him from the beginning. He went into the crawl space to check the interior condition of the roof which was something the majority of the other roofers didn't do. He also walked the roof. We had tons of questions and he answered each one fully and completely. The work took almost 2 days because there was so much sheathing to replace and, yes, they did show (without us asking) the rotten/warped sheaths. The workers were all professional and quiet and there was no debris left after the job was completed. The roof looks great and there are no more leaks. Just an excellent job from start to finis ...in fact, my neighbor was so impressed, he just had Keller reroof his house."

Roofing questions, answered by experts

Yes, materials like cool roofs and solar shingles may be considered.

It’s possible for a roofing estimate to change after the initial assessment, but in most cases, it shouldn’t. There’s always the risk that something unexpected will happen that causes prices to go up, like discontinued materials or your roofer discovering previously hidden damage to your decking when ripping off the old roof. However, experienced roofers should account for these circumstances in their initial estimates. Roofing contracts are binding, so always check your contract for language about how and why your numbers could change.

A roof's lifespan can range from 15 to 200 years, with an average of 25 to 50 years, depending heavily on the material, quality of installation, maintenance, and local climate. Asphalt shingle roofs are common and typically last 15 to 30 years; three-tab shingles have a lifespan of about 20 years, while architectural shingles can last up to 30. More durable materials have longer lifespans: metal roofs last 30 to 100 years, clay and concrete can last 50 to 100 years, and slate roofs can last up to 200 years with proper care. Regular maintenance, such as cleaning gutters and replacing damaged shingles, is crucial for extending the life of any roof.

Generally, roof flashing is installed under the shingles to create a watertight seal and prevent moisture from seeping in and causing damage. However, the exact placement can depend on the type of flashing. For instance, with step flashing, the shingles and flashing overlap each other, meaning the flashing is technically both over and under the shingles. Flashing also typically goes beneath the house siding and is often not visible from the ground.

Before hiring a roofing contractor, it's wise to ask several key questions. Inquire if they are licensed for roof replacement and repair and if they hold any special certifications. Ask if they will be completing all the work themselves or subcontracting parts of it. It's also important to understand the project timeline, whether they will remove the old roof or place new shingles on top, and how they will handle cleanup after the project is complete. Finally, ask about warranties for both work and materials, what recourse you have if issues like leaks arise, and if they can provide customer references.
