"Robert did an amazing job on my roof.   He is a very pleasant person to work with, and is very nice.  He replaced my roof very quickly.   I have had lots of comments from my neighbors about how good the roof looks.  I would recommend him to anyone else looking for a roofer. "

"Chris was very motivated and started the job promptly. His work ethic was great, staying late a couple of days late to complete job on time as agreed. He reviewed any issue found and was flexible when extra work was needed. The quality of the work was great in making the breezeway siding look the same as the garage, so with the paint job the house/garage improvement was dramatic. His pricing was reasonably and his clean-up appreciated. We would definitely recommend Chris to others and would engage him for work ourselves."

Roofing FAQs, answered by experts

A spray foam roof lasts 20 to 30 years if installed and maintained correctly. Spray foam roofs should be recoated every 10 to 15 years to maintain the UV protection and waterproof surface of the foam material. The longevity of spray foam roofing will depend on the thickness and density of the foam, the protective coating, and how well it’s maintained.

Underlayment exists under your tile roof. It helps protect your home by acting as a secondary water barrier. Often, when roof tiles fall off, underlayment that's in good condition can temporarily keep water from getting into the home. However, immediate replacement of missing tiles is crucial to avoid additional roof damage. 

The principal, common, and auxiliary rafters are the most frequently used types of rafters. Principal rafters are large and typically appear toward the edges of the roof. Common rafters are smaller than principal rafters. Some people may use a mix of common and principal rafters. The auxiliary rafter is not common, but it provides extra reinforcement for a principal rafter on a large building.

Hail damage is bad for a roof because it can leave the roof vulnerable to the elements. Hail may leave more than dents or scratches behind. It can actually cause the shingles to crack, which means water can leak into your home from the roof. Hail can also wear down the granules on the shingles. Without these granules, the shingles are weaker and more vulnerable to the elements, particularly wind. If the hailstorm is accompanied by high winds, it may take your shingles with it.

A roof can collapse from a leak if the leak is left unattended long enough. A collapse will happen when the structural components of your roof become saturated with water over time. The roof deck or rafters can slowly weaken until they can no longer support the weight of your roof.
