Best roofers near Spotsylvania, VA

There are several signs that indicate you’ll need new underlayment. Clear signs include missing or damaged roofing and exposing the underlayment to the elements. Additionally, if you notice water damage in your home by the roof after a storm, it could indicate that your underlayment may need to be replaced. If your gutters aren’t draining properly, it could also lead to rotting or water damage to the underlayment.

The cost to replace a roof typically ranges from $8,700 to $22,000, with a national average of around $9,200. The total cost depends on the size of your roof and whether you need a full replacement or can simply place new shingles over the old ones. A full replacement, which is necessary if the roof is several decades old or has multiple layers, is more expensive. This process involves tearing off the old roofing materials, inspecting and repairing the underlying structure, and then installing the new roof.

In some cases, yes, you can put a second roof layer over architectural shingles, but it depends on your home’s structural stability and the local building codes where you live. Architectural shingles are thicker and heavier than standard asphalt shingles, so you may need structural reinforcement or a structural engineer’s inspection before proceeding. Additionally, some building departments don’t allow for two roof layers, regardless of the roof type. You should ask a professional if ripping the old roof off before installing the new one is the best option for you.

Generally, the term “rolled roofing” refers to MSR (mineral surface roll) roofing. This type of roofing is similar to asphalt shingles but comes in a roll that’s unraveled and installed over your roof deck. There are many types of rolled roofing, including TPO, EPDM, and modified bitumen roofing (aka torch down roofing).
