Roofing: questions, answered with sources
Each answer cites the public sources it was checked against, with the date it checked them. Jobs that need a licensed pro in Virginia say so, and explain the job instead of teaching it.
Emergency Tarping
4 answers
How is a roof tarped after storm damage?
A roofer tarps a storm-damaged roof by assessing whether it is safe to work on, clearing debris, and covering the damaged area and the sound roof around it with heavy sheeting that is secured so wind and rain cannot get under it. It is temporary cover, not a repair, and the work happens on a hazardous roof, so it is a job for a licensed roofer.
How much does emergency roof tarping cost in Virginia?
We could not find a dated Virginia price for emergency tarping from an official source, so any single number would be a guess. The cost depends on the area covered, roof pitch and height, debris and decking, materials and timing. Your homeowners policy may pay the reasonable cost of protecting the roof, so keep receipts, photograph the damage and get written quotes.
Who tarps a roof after storm damage?
A licensed Virginia roofing contractor tarps a storm-damaged roof. Call your insurer first, then hire a roofer whose licence class and specialty you have checked with DPOR. Be wary of door-to-door offers after a storm, insist on a written contract, limit your deposit and never go up on the roof yourself.
How long can a tarp stay on a roof?
We found no official Virginia figure for how long a roof tarp can stay up, and it varies with the sheeting, how it is fastened and the weather. A tarp is temporary cover, so plan the permanent repair as soon as your insurer has advised you in writing. Ask the roofer who tarped it how long to expect it to hold, and have it checked after every storm.
Flashing Repair
5 answers
What is roof flashing?
Roof flashing is thin metal or roll roofing that keeps water out where a roof meets a chimney, wall, dormer, vent pipe or valley, or is cut through by a skylight. Shingles cannot seal those joints on their own. Failed flashing causes many roof leaks, so have a licensed roofer inspect and repair it rather than patching it with sealant yourself.
How much does flashing repair cost in Virginia?
No dependable, dated Virginia price list exists for flashing repair, so the cost depends on the job: how many flashings have failed, which ones, the roof's height and pitch, and any rotten decking or masonry behind them. Get three written, itemised quotes from licensed roofers, and keep the deposit to 10 percent or $1,000, whichever is less.
Who repairs chimney and roof flashing?
A licensed roofer is the usual first call for chimney and roof flashing. If the leak comes from cracked mortar or brick around the chimney, a masonry contractor may be needed too. In Virginia, work valued at $1,000 or more needs a licensed contractor, so check the licence on DPOR's lookup and get three written bids before you pay a deposit.
Why is my plumbing vent boot leaking?
A plumbing vent boot usually leaks because its rubber collar has cracked, shrunk or pulled away from the pipe, or the metal base has rusted, lifted or lost its seal. Sealant on top only slows the drip. A licensed roofer can find the cause, replace or retrofit the boot, and check for wet decking. Stay off the roof.
How long does roof flashing last?
There is no single figure: flashing life depends on the metal, the sealant, the roof it sits on and the installation. Metal flashing can outlast the shingles, while rubber vent collars and sealant joints wear out sooner. Have flashing checked twice a year, and ask a licensed roofer which pieces to renew when the roof is replaced.
Flat Roof Repair
3 answers
How is a flat roof leak patched?
A roofer first traces the leak to its real source, since water often travels before it shows inside, then repairs the defect in the membrane, seam, flashing or sealant using methods that match your roof system, and deals with any ponding. It is a job for a licensed Virginia roofer, because it involves hot materials, fall risk and a warranty to protect.
How much does it cost to patch a flat roof in Virginia?
A flat roof patch has no standard Virginia price, because roofers quote the repair rather than the roof. The cost depends on the roof material, how hard the leak is to trace, what is damaged beneath the membrane, ponding, access and warranty. Get at least three written quotes on the same scope, with the down payment limited to 10 percent or $1,000, whichever is less.
Who repairs flat roofs on houses?
A licensed roofing contractor repairs flat roofs on houses, ideally one that regularly works on your membrane type, such as EPDM, TPO, modified bitumen or built-up. In Virginia, DPOR says work valued at $1,000 or more needs a valid contractor licence in the right category. Check the licence, get three written estimates and limit the deposit.
Gutter Repair
5 answers
How do I fix a leaking gutter seam?
Wait for a dry day, clear the gutter, scrape the old sealant out of the leaking joint, let it dry, and lay a fresh bead of gutter sealant over the seam from inside the trough. Let it cure before the next rain, then test it with a hose. A joint that has pulled apart needs refastening first, and anything above the first storey is a job for a pro.
How much does gutter repair cost in Virginia?
It depends on what is broken and how high it is. Resealing a leaking joint or rehanging a short run on a single-storey house is a small job; replacing sections, rotten fascia or downspouts, or working two storeys up costs much more. Get at least three written, itemized bids on the same scope, and check the licence of anyone quoting $1,000 or more.
Should I repair or replace my gutters?
Repair them when the trouble is in one place and the metal is sound: a leaking joint or two, a few loose hangers, one dented section or a downspout. Replace them when most seams leak, the metal is rusted through or split, the gutter sags in several places, it overflows even when clean, or the fascia behind it is rotten along much of the run.
Why are my gutters sagging?
Gutters sag when they are carrying more weight than their hangers can hold. The usual causes are hangers spaced too far apart, spikes or screws working loose, debris and standing water, ice and snow, a run that has lost its slope, bent hangers from ladders or branches, and soft fascia behind them. Find which one it is before you refasten anything.
How do I keep gutters from sagging?
Keep the weight down and the support up. Clean gutters at least once a year, more often under trees, and before winter; keep downspouts clear so water never stands; make sure hangers are tight and close enough together; keep the slope toward the downspout; reseal joints so water stays off the fascia; and never lean a ladder on the gutter.
Ice Dam Removal
5 answers
How are ice dams removed safely?
Safely means by a trained crew, not by you on a ladder in the snow. A removal crew clears snow from the lower roof, opens channels so trapped meltwater can drain, takes the ice down without chopping at the roofing, and checks the attic for wet insulation. Hacking at a dam damages roofs and injures people, and the lasting fix is stopping the attic heat loss behind it.
How much does ice dam removal cost in Virginia?
Ice dam removal has no standard price in Virginia, and the bill depends on the job: how long and thick the dam is, how high and steep the roof is, whether water is already inside, and what repairs follow. Ask licensed contractors for written quotes that price the removal separately from roof, gutter, insulation and interior repairs.
Who removes ice dams?
Roofing contractors are the usual call to remove an ice dam and repair what it damaged, and some snow removal and gutter companies offer removal too. In Virginia, check the business's contractor licence with DPOR for any job over $1,000. To stop the dams coming back, hire an insulation or weatherization contractor, ideally after an energy audit, to fix the attic heat loss behind them.
Why do I get ice dams on my roof?
You get ice dams when heat escaping from the house warms the upper roof enough to melt snow while the eaves stay below freezing. The meltwater runs down, refreezes at the cold edge and builds a ridge that traps more water behind it. Air leaks into the attic, thin insulation over the outside walls, blocked ventilation and warm ducts or chimneys are the usual sources of that heat.
How do I prevent ice dams?
Prevent ice dams by keeping the whole roof cold. Seal the air leaks from the house into the attic first, then bring attic insulation up to the recommended level and keep soffit-to-ridge ventilation open. Work on the roof itself belongs with a licensed roofer, and an ice barrier along the eaves at reroofing time limits the damage if a dam forms.
Metal Roof Repair
4 answers
How are leaking screws on a metal roof fixed?
A roofer first works out why each screw leaks, then reseats it or replaces it. A screw driven too loose never compresses its washer, one driven too tight crushes it, a stripped hole needs an oversized screw or a fresh hole, and an aged washer needs a new fastener. Caulk smeared over the heads is usually a stopgap. On a roof, this is work for a licensed roofer.
How much does it cost to fix a leaking metal roof in Virginia?
No dependable, dated price list exists for metal roof leak repair in Virginia, so the price comes down to the job: a few reseated screws, every exposed fastener on the roof, a replaced standing seam panel, or new flashing. Roof type, height, slope and hidden damage drive it. Get three written, itemized quotes from licensed roofers and keep the deposit to 10 percent or $1,000, whichever is less.
Can any roofer repair a standing seam metal roof?
Legally, any contractor whose Virginia licence covers roofing may take the job, but not every roofer has the experience or tools for it. Standing seam panels hide their fasteners under interlocking seams, some systems need a mechanical seamer, and some designs require neighbouring panels to come off to replace one. Hire a licensed roofer who works on your type of system regularly and respects its warranty terms.
Why is my metal roof leaking at the screws?
Most screw leaks on a screw-down metal roof come back to the sealing washer: a screw driven too loose never compresses it, one driven too tight crushes it, and washers age with sun and the panels' thermal movement. Stripped holes, angled screws and rust from mixed metals or left-behind shavings cause leaks too. Some apparent screw leaks are really side laps, flashing or condensation.
Ridge Vent Repair
5 answers
What does a ridge vent do?
A ridge vent lets hot, humid air escape from the attic through an opening along the roof peak while cooler air enters at the soffits. That airflow helps protect the roof deck and insulation from heat and moisture and helps reduce ice dams. It only works with a clear intake, and repairs belong to a licensed roofer.
How much does ridge vent repair cost in Virginia?
There is no single Virginia price, and we found no dated one from a primary source to quote. The cost depends on how much ridge needs work, roof height and pitch, matching cap shingles, hidden deck damage and whether the attic has real air intake. Get at least three written, itemized quotes from licensed roofers.
Should I replace my ridge vent when I get a new roof?
Usually yes. The ridge is exposed during a re-roof, so a new vent costs mostly material, and a worn or mismatched vent undercuts a new roof. Have the roofer check the attic intake and insulation, then write the vent type, length and any intake work into a written, itemized contract with a licensed roofer.
Why is my ridge vent leaking?
A ridge vent that seems to leak is usually one of four things: rain or snow getting past a damaged or lifted vent or cap, condensation from warm, humid house air in a cold attic, melting snow backing up as an ice dam, or a leak elsewhere running to the ridge. Timing tells them apart, and a licensed roofer should confirm the cause.
How do I know if my attic is ventilated well?
A well-ventilated attic has open soffit intake at the eaves, a clear exhaust such as a ridge vent, insulation kept off the vents with a gap under the deck, and no frost, damp, stained wood or mold. Virginia Cooperative Extension suggests about 1 ft2 of net vent opening per 150 ft2 of attic. Check from the attic floor and have a roofer fix problems.
Roof Leak Repair
4 answers
What should I do when my roof starts leaking?
Limit the damage indoors, document it, and call a licensed roofer. Catch drips, move belongings, dry wet materials within 24 to 48 hours, stay away from wet electrical equipment, and photograph everything. Tell your insurer right away and keep receipts for emergency repairs. Do not climb onto the roof: covering or patching it is work for a licensed pro.
Who should I call for a roof leak?
Call a licensed roofer first, and your homeowners insurer the same day if the leak is active. A leak repair worth $1,000 or more needs a Virginia licensed contractor, so check the licence on DPOR's lookup, get at least three written bids, limit the deposit, and ask the roofer to explain exactly where the water is getting in.
How do I find where my roof is leaking from?
Trace it from inside, then let a roofer confirm it outside. Water often runs along rafters before it drips, so the stain is rarely under the hole. Look at the attic from the hatch for wet insulation, dark wood and stained nails, note when it leaks, and photograph it all. The roof itself is a job for a licensed roofer.
How do I catch roof leaks early?
Look for the signs before water reaches a ceiling. Check the attic from the hatch for damp insulation, dark wood and mold, walk the yard after storms for loose shingles and overflowing gutters, and watch ceilings for new stains. Have a licensed roofer inspect the roof itself each spring or fall and after severe weather.
Shingle Replacement
5 answers
Can a few missing shingles be replaced without a new roof?
Yes. A few missing shingles can usually be replaced as a repair, with no new roof, as long as the shingles around the gap are still sound. The U.S. Forest Service's roofing guide says to repair missing or torn shingles as soon as possible, because nearby shingles are easily ripped off. This is roof work, so hire a licensed roofer rather than climbing up yourself.
How much does it cost to replace missing shingles in Virginia?
There is no single Virginia price for replacing missing shingles. A repair is priced by the job: how much is damaged, the pitch and height, the shingle type, any decking or flashing underneath, and the roofer's minimum charge. Get two or three itemized written quotes from licensed roofers and keep the deposit to 10 percent or $1,000, whichever is less.
Should I replace missing shingles or the whole roof?
Replace only the missing shingles when the rest of the roof is sound; replace the whole roof when the shingles are old, curling or failing, or damage is widespread. The U.S. Forest Service's roofing guide lists 15 to 25 years for 3-tab and 20 to 30 years for architectural shingles. Have a licensed roofer assess the roof and put the findings in writing.
Why are my roof shingles curling?
Most often age: the U.S. Forest Service says old, worn-out shingles curl, split and lose their waterproofing. Heat from a poorly ventilated attic, moisture, dark colours in strong sun and poor nailing or sealing at installation are the other usual causes. A few curled shingles can be repaired; widespread curling usually means the roof is near the end of its life. Have a licensed roofer look.
How do I keep shingles from blowing off?
Keep them sealed, nailed and sound: have a licensed roofer inspect after storms, repair lifted or missing shingles early, and ask for wind-rated shingles with full nailing when you repair or reroof. The Building America guide says codes require not less than four fasteners per strip shingle and recommends six nails per strip in high-wind areas. Old, curling shingles blow off easily, so a worn roof needs replacing, not patching.
Skylight Repair
3 answers
How is a leaking skylight repaired?
A roofer first finds where the water actually gets in, since the glass is rarely the culprit. The usual fixes are re-flashing the skylight, replacing a failed seal or curb, or replacing the whole unit when it is old. Roof work, so hire a licensed roofing contractor; a dab of caulk is a short-term patch at best.
How much does skylight repair cost in Virginia?
No public Virginia price list exists for skylight repair. A repair is usually cheaper than a replacement, and for a replacement, VELUX's national estimates, when we checked on October 26, 2026, ran from $2,000 to $3,600 for a fixed skylight, installed. Flashing, curb and roof condition decide the repair price, so get written quotes that name the work.
Why is my skylight leaking?
Most skylight leaks come from the flashing, underlayment or seal around the unit failing, not from the glass. Age, debris that blocks water flow, and a poor installation are common causes. Some drips are really condensation. Put a bucket under it and dry the area, then have a licensed roofer find the true entry point.
Soffit Repair
4 answers
How do I replace a vinyl soffit panel?
On a single-storey eave you can reach from a ladder, replace one panel by unhooking the damaged piece from its channels, measuring from the wall to the fascia and cutting the new panel 1/2 inch shorter, then flexing it into the channels and fastening it loosely. Match vented or solid, and check for a nest or wet wood behind it before you close it up.
How much does soffit repair cost in Virginia?
There is no honest single Virginia price, and a national average says little about your house. A job is priced by how many panels or feet of soffit are damaged, the material, how high the eave is, and what is hiding behind it, such as rot or animals. Get three written bids on the same scope and ask each to itemise the repair and any hidden-damage allowance.
Who repairs soffits, a roofer or a gutter company?
Either can, but neither is automatically the right call. Hire a roofer when the problem comes from the roof edge or you are re-roofing; hire a siding, exterior or home-improvement contractor for soffit on its own. A gutter company fits when gutters and fascia are being redone too. In Virginia, check that whoever quotes holds a contractor licence if the job is $1,000 or more.
Why is my soffit sagging?
A sagging soffit usually means water, over-tight fastening or a span with too little support. Water from a roof edge leak, overflowing gutter or attic moisture soaks and softens the wood, while vinyl nailed tightly cannot expand and bows. Check for stains, soft wood, gutter overflow and wet insulation first. Dry and bowed is often simple; wet and soft is a contractor job.
Storm Damage
3 answers
What are the signs of hail or wind damage on a roof?
Wind damage shows as shingles that are missing, torn, creased or lifted, often with exposed underlayment. Hail damage shows as random strike marks in different sizes, with a bruise you can feel in the shingle, and dented cars, fences, shutters or siding nearby. Check from the ground, photograph everything, and have a licensed roofer confirm.
How do I file a complaint about a storm-chasing roofer in Virginia?
First check whether the roofer holds a Virginia contractor licence, because that decides where the complaint goes. Complain in writing to the contractor, then to the Board for Contractors at DPOR if they are licensed. If they are unlicensed, DPOR can pursue criminal action. Also contact the Attorney General's Consumer Protection Section for deceptive sales or price gouging.
Why do roof leaks show up weeks after a storm?
Because the water has to get through several layers before you see it. A storm can tear shingles or bend flashing, but the underlayment, deck, insulation and drywall soak up the first rain and hide it. A stain appears only once they are saturated, often after a later rain. Have a licensed roofer inspect the roof and attic.
