Our Simple Process for Roof Replacement

Discover the simple steps for a successful roof replacement! First, we thoroughly assess your roof to determine if repair or coating is a viable solution. If a new roof is necessary, we’ll measure your roof and provide a written estimate. Next, we begin by removing the existing roof membrane and any underlying layers. Many roofs in Virginia have multiple layers, which is not up to code. Once the roof is clear, we inspect the decking and replace any damaged planks. Then, we install new underlayment and the homeowner’s chosen roofing material.

There are many reasons why your roof may need repairs, an obvious sign is a water leak inside your home, but often repairs are needed long before a leak is detected. It’s a good idea to have a qualified roofing contractor inspect your roof so you can have a baseline on your roof’s condition before a big storm hits, and so you can address issues while they’re still minor and inexpensive. A repair that costs a couple hundred dollars today can easily cost a few thousand down the road if left unfixed.

Many times a roof repair can save you from spending the big money on a roof replacement, but a lot of times this is not possible. The only way to know is to Contact Us and let us give you a free estimate to see if we can perform a roof repair or if it’s progressed to a roof replacement.
