ROOF REPLACEMENT · POTOMAC, MD
Potomac, MD Roof Replacement & Roofing Contractor
Complete roof replacement in Potomac, MD. We are GAF Master Elite, roughly the top two percent of roofing contractors nationally, and we have been doing this out of Woodbridge, Virginia, since 1993. We hold Maryland MHIC license #05-131843 for our Montgomery County work.
What we actually find on Potomac roofs
Potomac is large lots and large roofs. Regent Park and the Potomac Falls estates from the 1960s, River Falls and Fox Hills from the late 1960s onward, and Avenel from the mid-1980s are all past or at replacement age, and the newer custom homes on two-acre lots bring steep pitches, multiple planes, dormers and long valleys that a builder-grade roof was never going to carry for thirty years.
Most leaks we get called about in Montgomery County are not shingle failures at all. The shingles look fine from the driveway. The problem is a cracked pipe boot, a valley that was never lined properly, or step flashing somebody caulked instead of replaced. Water is patient and it only needs one of those.
Avenel, Falconhurst, Potomac Falls, River Falls, Glen Hills and Potomac Village are where our Potomac crews spend most of their time, though the service area covers 20854, 20859 and 20817 and a good deal past it.
The five things that put a roof in Potomac on our schedule
Pipe boots that have split
The rubber collar around each vent pipe is usually the first component on the roof to die. Sun works on it, it hardens, and somewhere around year twelve to fifteen it cracks in a ring around the pipe. Water then runs down the outside of the pipe, into the attic, and shows up on a bedroom ceiling twenty feet away. Almost nobody spots this from the ground.
An attic that cannot breathe
Air is supposed to come in low at the soffit and leave high at the ridge. What we find in a lot of Potomac attics is insulation shoved tight against the soffit, choking the intake, with a ridge vent up top pulling against nothing. The result is an oven in summer and condensation in winter, and the roof pays for both.
Old flashing sealed up and left alone
Around a chimney the metal has to be cut into the mortar joint, not smeared over with sealant. We pull plenty of chimney flashing in Potomac that was caulked at some point and has been quietly leaking behind the brick ever since. The stain shows up on a wall, not a ceiling, so it gets blamed on the chimney.
Decking nobody looked at
You cannot judge decking until the old roof is off. On older Potomac homes we regularly find soft plywood around a chimney or under a valley where water has been getting in for years. We tell you what we find, show you, and price the replacement by the sheet rather than guessing up front.
A second layer hiding the first
Layering a new roof over an old one was normal practice for a long time. It traps heat, it doubles the weight, and it means nobody has inspected the decking in decades. We tear off to the deck every time. It costs more in disposal and it is the only way to know what you actually have.
Roofing systems we install in Potomac
We are a GAF Master Elite contractor. GAF awards that to roughly the top two percent of roofing contractors in the country, and it is not a sticker you buy: it requires licensing, insurance, a track record and ongoing training. It also lets us offer the GAF Golden Pledge, which is the only GAF warranty where GAF sends its own inspector to your home before the coverage is issued.
Architectural shingles
The default choice on most Potomac homes and the right one for the money. Dimensional, heavier than a 3-tab, and rated for the wind we actually get here. If you are replacing a builder-grade 3-tab this is the obvious step up.
Designer shingles
Heavier profiles that read as slate or shake from the street. Worth it on homes where the roof is a big part of what you see from the curb, which in Potomac is a lot of them. Costs more and looks it.
Cedar shake
Real wood, for homes where the architecture asks for it and the association allows it. It is a specialty product with specialty installation requirements, and it is not something every roofer in Potomac should be touching.
Underlayment and ice barrier
Synthetic underlayment over the whole deck, and ice and water shield in the valleys and along the eaves where backed-up ice pushes water uphill under the shingles. This is the layer that saves you in February.
Ventilation
Balanced intake and exhaust, sized to the attic. We check that soffit intake is actually open rather than packed with insulation, because a ridge vent with no intake is just a hole in your roof.
3-tab shingles
Still available, still the cheapest option, and still what a lot of Potomac homes came with from the builder. We will install it if that is genuinely what you want, but we will tell you honestly what you give up.

What a roof replacement actually looks like
Most single-family homes in Potomac come off and go back on in one to two days. Steep pitches, multiple dormers, several roof planes or a cedar shake install take longer. We will give you the realistic number before you sign, not the optimistic one, and we do not open up a roof we cannot dry in the same day.
- We measure and look it over. Someone comes out for a free estimate, gets on the roof where it is safe to, looks at the attic, and tells you what is failing and what has life left. You get a firm written price. No charge and no obligation.
- You pick the system and the color. If your community has architectural review, this is where we hand you the product data sheets and manufacturer color names so your application goes in complete the first time. We work closely with the committees, we have a great relationship with plenty of HOAs in the area, and it has never been a problem for us.
- We protect the property. Tarps over landscaping, plywood against the siding where debris will land, and a dumpster placed where it will not damage the driveway.
- Full tear-off to the deck. Every layer comes off. That is when we find out about the decking, and we show you anything that needs replacing before we replace it.
- The system goes on. Underlayment, ice and water shield at the eaves and valleys, new flashing, new pipe boots, ventilation corrected, then the shingle.
- Cleanup and a walk-through. Magnets over the lawn and driveway for nails, debris hauled, and we walk it with you before we leave.
What a Potomac roof replacement actually costs
Anyone who gives you a number over the phone is guessing, and the guess is usually low so they can get in the door. Real price comes down to a handful of things, and all of them need eyes on the house.
- Square footage and pitch. A steep roof is slower and needs staging
- How many layers have to come off and go in the dumpster
- Decking condition, which nobody knows until tear-off
- Penetrations and planes such as dormers, skylights, chimneys and valleys
- Flashing and ventilation work the roof actually needs
- Which shingle you choose, from 3-tab up to designer
We measure your Potomac home, tell you what we find, and put a firm written price in front of you. If we discover bad decking after tear-off, you see it and you know the per-sheet price before we touch it. Financing is available if you would rather spread it out.
Storm damage is not what most people picture
Most of the storm damage we deal with around Potomac is invisible from the ground and stays invisible for years. Hail dings the mat without stripping much granule. Wind breaks the adhesive strip. Neither one leaks the week it happens, which is exactly why it gets missed until there is a stain on a ceiling.
You can check most of it without a ladder. Soft metal shows hail first, so look at the gutters, the downspouts, any aluminum trim, and the top of the air conditioner. Then look at where the downspout empties. If there is a pile of granules building up at the splash block, the roof is shedding its surface.
If a storm has genuinely opened up a Potomac roof, we do emergency roof replacement and we will get you on the schedule. What we will not do is sell you a patch. Splicing new shingles into a roof that is already at the end of its life buys a year and creates a seam that fails next.

Roofing questions from Potomac homeowners
Do you repair roofs in Potomac, or only replace them?
We replace. Sunshine Contracting is a full-replacement roofing contractor, and that is a deliberate choice rather than a limitation. Patching a section of a roof that is already at the end of its life puts new material against old and creates a seam that becomes the next leak. When a Potomac roof has taken real damage and cannot wait, we move it up the schedule, but the work is still a full replacement.
Who actually does the roofing work on my Potomac home?
Our own crews. They work for Sunshine, they are factory trained and certified, and they are not a subcontracted crew assembled for the week. That matters more than it sounds: manufacturer warranties assume the system went on exactly to specification, and subcontracted labor is where that assumption tends to fall apart.
How soon can someone look at my Potomac roof?
Usually within a few days. Call (703) 499-8654 and we will get a consultation on the calendar. Someone comes out for a free estimate, looks over the roof and the attic, explains what is actually going on, and leaves you with a written price. No charge, no obligation.
Do you work on roofs and siding anywhere else in Montgomery County?
Yes. Avenel, Falconhurst, Potomac Falls, River Falls, Glen Hills and Potomac Village are where our crews spend most of their time in Potomac, and we cover Potomac, Chevy Chase and the rest of lower Montgomery County under our Maryland license. We are based in Woodbridge, Virginia, and work across Northern Virginia as well.
What warranty comes with a new roof in Potomac?
Manufacturer coverage comes through GAF. Because we are GAF Master Elite we can offer the Golden Pledge, which is the only GAF warranty where GAF sends its own inspector out to your home before the coverage is issued. It provides 50-year non-prorated coverage for manufacturing defects and GAF-backed workmanship coverage for up to 25 years. Which coverage applies depends on the system you choose, and the exact terms are written on your estimate before you sign anything rather than described vaguely at the kitchen table.

Somebody comes out and actually gets up there. We look at the boots, the flashing, the valleys and the ventilation, then we tell you honestly what shape it is in. Sometimes the answer is that you have three or four years left. You get that in writing either way.
