"called Arian about a roof repair, he came next day . He gave me a good estimate for the repair, after discussing the repair we talked about a new roof because the roof was over 30 years old. He gave me a good price. He and his 5 guys came 2 days later. They finished the job in 6 hours did a good job at a fair price and left the property in clean condition"

Roofing FAQs, answered by experts

Many homeowners believe that a modern home looks better with a flat roof than a sloped roof. A flat roof can provide several aesthetic benefits for modern homes. Among the pros and cons of a flat roof for a modern home design are the clean lines and straight edges that it delivers to improve curb appeal.

Your chimney needs a structurally sound chimney cap, protective lining, damper, chimney flashing, and brick and mortar to prevent water from goind down your chimney. A pro can help you identify where the issue is so that you can stop water from coming down the smoke shaft, through your damper, and into your home.

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.

Yes, a roof blister can cause a leak if it gets to the point where it pops. Prior to popping, a roof blister is just an aesthetic issue, but once it pops, you’re left with a small hole in the shingle. Water from rain and snow can easily get inside this hole and interact with your underlayment, roof decking, and the building material below.

Roof work is dangerous and exacting, and a misstep could lead to even more costly repairs, so we do not recommend DIYing. If you are dead set on giving it a go, practice safety measures. Wear a harness, only work during mild weather, and have a partner to help. Potentially DIY-friendly jobs include patching up small leaks, sealing areas around the chimney, and replacing a few shingles.
