One of the most common failure points on newer construction homes in SOMD are front porch roofs.

These porch roofs are a huge focal point on the front of the home, but are almost never done correctly.

❎ No Counter Flashing
❎ No Drip Edge

We replaced all the plywood (which was rotted from leaks of course) and got new TPO Roofing properly installed with drip edge AND counter flashing.

We're more than just a company to install a new roof, we're specialists that can solve any of your roofing issues.

We're prepping for OUR Netflix documentary:

Sandy Bottom: An Insurance Saga ⚠️

This beautiful home (currently on the market, btw) in Hughesville was on the receiving end of storm damage back in the Spring. A claim was opened after our inspection, and a subsequent 2 month long saga of phone calls, inspections, emails etc. was endured to FINALLY get to the finish line here at the end of summer.

But now the next owner of this home will have the peace of mind and security of a JMJ roof over their heads 🏡

❗️This time of year, we get tons of calls about gutter systems in heavy rainstorms. ❗️

During monsoons, no gutter system is going to catch and drain away 100% of the water, but there are steps we take to mitigate splash-over in high-flow areas. The main one being: Splash Guards.

Here is a prime example of one on my own home, doing its job during this mornings rain storms 💪🏼

Give us a call and we won’t let the rain ruin your parade ☔️
