"Keystone Roof solutions was a lifesaver, while everybody else came out with estimates that were completely high unrealistic. Keystone offered a very affordable option for our roof replacement needs. They were also very helpful , doing extra work for a very reasonable price. They replaced our roof in a matter of 3 days and kept us posted with every single detail during the process. Don't go Anywhere else."

"They worked with us every step of the way to get our leaky roof replaced. Even made a personal visit before the job was started to make sure we got what we wanted and the path was clear for a smooth installation. Contacted us several times before and after to make sure we were pleased."

Roofing FAQs, answered by experts

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

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.

Metal roofing offers durability, energy efficiency, and resistance to extreme weather conditions. It can reduce cooling costs, has a longer lifespan than traditional materials, and provides a sleek, modern appearance, adding value to a property.

A well-maintained tile roof can last anywhere from 40 to over 100 years, with its exact lifespan depending on the material and level of care. Proper maintenance, which includes keeping the roof clean, free of debris, and performing routine repairs for any cracked tiles, is crucial for longevity. The lifespan varies significantly by tile type:

  • Clay, terracotta, and slate tiles are highly durable and can last over 100 years.

  • Concrete tiles typically last from 30 to 100 years.

  • Metal tile roofs generally last between 40 and 70 years.

  • Composite tile roofs have a lifespan of 20 to 50 years.

Be aware that maintenance for a tile roof can sometimes be more expensive than for an asphalt roof.

The best material to sheath a roof will depend on your budget and if you require the strength of more robust materials. For most homes, the added strength is unnecessary, and oriented strand board, or OSB, makes sense. It’s inexpensive and robust enough for most roof types. Another popular but slightly more expensive option is plywood.
