A New Roof for Your Columbia Home

For a covering-only replacement, no. Columbia is unincorporated Howard County, so the Department of Inspections, Licenses and Permits is your building office, and the county’s adopted building code exempts "replacement of roof coverings with no other structural repairs." The code carries an exception for up to 64 square feet of roof sheathing, though that clause is ambiguously drafted and worth confirming with DILP at 410-313-2455 on your specific job. The approval that will actually affect your project in Columbia isn’t the county’s. It’s your village’s.

It depends entirely on whether anything is changing, and the line is finer than people expect. Wilde Lake’s guidelines put it this way: "An application is not required to replace a roof with material of the same color, style and composition as the existing roof. However, if the repair projects will involve a change in color, materials, or style then you must apply for AC approval." So a true like-for-like replacement needs nothing. But upgrading from a three-tab to an architectural shingle, or picking a different color, which is what most homeowners actually want, is a change and needs approval before work starts. Rules vary by village, so we check yours.

No, and it matters for your roof. The Columbia Association is a private nonprofit that manages open space, paths, and recreation facilities across Columbia. It’s not a government and it’s not your architectural authority. Each of the ten villages, Wilde Lake, Harper’s Choice, Oakland Mills, Owen Brown, Long Reach, Kings Contrivance, Hickory Ridge, Dorsey’s Search, River Hill, and Town Center, is its own incorporated association with its own Architectural Committee and its own recorded covenants, and those covenants are part of your deed. Your village Covenant Advisor is who you want, not CA.

Due, mostly. 57.2% of Columbia was built between 1970 and 1989, with the 1970s alone accounting for 31.5% of the housing. That puts the bulk of the community on its second or third roof, and the original decking has now spent fifty years under whatever the last two roofers left behind. Howard County’s signature hail day was May 22, 2014, with 1.75 inch stones at Highland, and 1.50 inch hail fell at Glenwood as recently as May 2025. On a roof of that age, hail damage from any of those is worth a look you can’t do from the ground.

The price comes down to five things: the number of squares of roof area, the pitch, how many stories the house is, the condition of the decking underneath, and how many layers of old shingle have to come off. Two houses on the same street can differ by thousands on decking and tear-off alone, which is why we won't quote a roof over the phone. Every estimate is free and on-site, and it comes back the same day with both packages priced so you can see exactly what you're choosing between.

Most roof replacements run 3 to 5 days from tear-off to final walkthrough, and one-day installs are available on qualifying homes. The install itself is often a single day on an average home; the rest of the window is material delivery, weather, and any approval your HOA or historic district needs first. You get the schedule before the crew arrives, not after.

If the damage is localized and the roof still has service life left, repair is the right call and we'll tell you so. Replacement makes sense when the shingles are at the end of their life, when there's damage across multiple slopes, or when you've already patched the same roof more than once. We inspect the attic and the decking before making that call, because what a roof looks like from the driveway isn't the whole story.

It depends on why the roof failed. Insurance covers sudden damage from wind, hail, or a storm. It doesn't cover a roof that simply wore out. We document the damage for your carrier, handle partial approvals, and regularly overturn denied claims. If a claim isn't the right path, we'll say so, because a denied claim on your record doesn't help you.

We show you before we replace it. Decking condition is invisible until the old roof is off, which makes it the most common reason a final number moves off the estimate. We agree the per-sheet price for decking replacement up front, and you get photographs of anything we pull.

Because a roof with bad ventilation dies early. Trapped heat and moisture cook shingles from underneath, shorten the life of the roof, and can void the material warranty. Ventilation is part of the roof system, not an upsell. We inspect the attic and assess ventilation on every job, and we'll tell you if what's up there is undersized for the roof going on top of it.

We don't do it as a default and we generally advise against it. A layover hides the decking, adds weight, traps heat, and shortens the life of the new shingles, and most manufacturers won't warranty the result. Tearing off costs more up front, and it's the only way to see and fix what's underneath.

Felt is tar paper. It tears when a crew walks on it and it holds water once it gets wet, which is a problem on the one layer that is supposed to shed water if a shingle ever lifts. Synthetic underlayment is a woven sheet that does not tear underfoot and does not absorb. Both packages we install use synthetic across the entire deck.

Starter is a sealed strip along every eave and rake, which is exactly where wind gets its grip on a roof. It also does something most homeowners never hear about: on the Platinum package the starter is made by TAMKO to bond to the Titan XT shingle, and that single component is what takes the wind warranty from 130 mph to 160. A competitor quoting the same shingle with generic starter isn't selling the same roof and can't register the same warranty.

Nobody knows for certain until the old roof comes off, and any contractor who tells you otherwise on the driveway is guessing. What we usually find is one of four things. Half-inch to five-eighths CDX plywood is what we want, and it's ready for a new system as-is. OSB is acceptable while it's dry. Three-eighths plywood and older plank decking typically need to be addressed before shingles go on, because nails don't hold reliably in either one.

It's a limited warranty with conditions, not a performance guarantee. TAMKO's WindGuard 160 mph coverage applies to the Titan XT shingle installed with TAMKO starter and TAMKO hip and ridge. The shingle on its own does not qualify. TAMKO also states plainly that its limited warranty does not cover hurricanes, whatever the product does in a storm, so nobody should be selling you one on that basis.

It doesn't have to be, but the highest warranty tier requires it. TAMKO's DiamondShield program requires four TAMKO accessories: starter, underlayment, ice and water shield, and hip and ridge. Install a TAMKO shingle with generic components and the roof is not eligible for that coverage at any price. That is an eligibility rule TAMKO wrote, not an upsell we invented.

Class 3 is an impact rating from UL 2218 laboratory testing, and the Titan XT shingle on our Platinum package carries it. Whether it lowers your premium is a question for your agent. Some carriers discount impact-rated roofing and many do not, and it varies by state and by policy, so it is worth asking rather than assuming either way.
