Energy efficiency lives or dies at the seams. I have seen pristine new windows leak like sieves because of a sloppy air seal, and eighty-year-old sashes outperform modern units thanks to meticulous detailing and tune-ups. The same goes for roofs. Shingles get the spotlight, but the work at penetrations, edges, and transitions determines whether your attic becomes a comfort asset or a money pit. If you are comparing a roofing contractor or window company, ask how they plan to air seal, not just what brand they sell. The difference shows up in your utility bill and in how your home feels on a windy night.
Why air sealing beats chasing higher R-values
Insulation slows heat flow, but air movement carries heat and moisture far faster. A one-eighth-inch gap around a window unit can leak more energy than several square feet of insulated wall. Air sealing attacks that convective highway. When you tighten the building shell at windows, roofs, and wall penetrations, you cut drafts, lessen stack effect, and reduce the load on heating and cooling equipment. The typical home loses 20 to 40 percent of conditioned air through uncontrolled leakage. Plug half of that, and you can see paybacks within a season in cold climates, and within a year or two in mixed and hot climates.
I measure outcomes rather than rely on brochure claims. On blower door tests, a mid-century ranch I worked on in the Midwest dropped from 11.5 ACH50 to 6.2 ACH50 with targeted air sealing at window perimeters, top-plate gaps at the attic, and around can lights. The homeowner reported a 22 percent reduction in winter gas use compared to the previous year with similar degree days. We did not add an inch of attic insulation on that visit. We simply stopped air from moving where it should not.
Where window performance succeeds or fails
You can buy the best glazing on the market and get mediocre results if the rough opening and perimeter seal are ignored. Conversely, a reasonably efficient double-pane window can perform admirably when installed with care. Three elements matter most at windows: the flashing to keep liquid water out, the air barrier connection to the wall, and the insulation of the gap between the window unit and the framing.
On new installations and replacements set into a reframed opening, I want a continuous, shingle-lapped flashing system that starts with a sill pan or liquid-applied sill membrane that directs any incidental water to the exterior. Side and head flashings should overlap in a top-over-bottom sequence, with end dams or turned-up corners at the sill. This protects the assembly from rot and prevents pressure-driven rain from finding a path inside.
For air control, the window frame must connect to the wall’s air barrier. Depending on the wall system, that could be housewrap, a taped sheathing panel, or a fluid-applied membrane. I like to see a compressible gasket or high-quality tape that bonds frame to WRB, then a secondary interior air seal with backer rod and sealant where trim meets the jamb. The interior seal is not optional. That is the layer that stops conditioned air from escaping and stops humid air from entering the cavity and condensing in winter.
The cavity between the window unit and the rough opening should be insulated with low-expansion foam or mineral wool. Do not blast in high-expansion can foam labeled for general gaps. It can bow the frame, change reveal lines, and make sashes stick. Look for window-and-door foam, use a light touch, and trim back any foam that expands past the plane so you can install the interior sealant properly with backer rod. In old houses, I often prefer mineral wool in the cavity and a careful bead of sealant at both the interior and exterior trim lines. It is more forgiving, and I can keep the window square while I work.
What roofers control that affects your energy bill
A roof is a weather shell, but it is also a pressure boundary if detailed well. Roofers have control over a surprising number of air leaks. The top plate to drywall joint, bath and kitchen duct penetrations, recessed lights, plumbing stacks, chimney surrounds, and skylights are all territory a good crew can improve. The best roofing companies coordinate with insulation contractors to air seal before new shingles go on or when decking is exposed during a roof replacement.
If you are interviewing roofers, ask what happens at the attic plane. You want them to describe how they will:
- Seal top-plate and drywall cracks, light boxes, and chases with foam or mastic before adding attic insulation. Flash and air-seal bath fans and range vents with rigid duct, sealed seams, and insulated boots to the exterior. Box and gasket around chimney or flue chases with fire-safe materials, then add metal flashing and high-temperature sealant. Replace leaky can lights with ICAT-rated fixtures or cover and seal them per code-approved methods. Install an air barrier at knee walls, attic hatches, and pull-down stair openings with weatherstripping and rigid covers.
I am wary of any roofing contractor near me who talks only about shingles, ridge vents, and warranties. Venting and weathering matter, but without air-sealing, you can pull attic air through every crack in winter and every humid evening in summer, which hurts both comfort and durability.
Attic ventilation, air sealing, and the moisture trap
Ventilation and air sealing often get confused. Venting is about removing moisture and heat that does manage to enter the attic. Air sealing aims to keep house air out of the attic in the first place. If you add ridge and soffit vents without sealing the attic floor, you increase suction at the ceiling plane on windy days. That can drag more indoor air through ceiling penetrations, which increases energy loss and, in winter, deposits indoor moisture on cold roof sheathing. The result is frost in January and a drip in March.
I worked on a Cape with chronic ice dams. The owner had paid for a roof replacement two years prior with a well-known brand and a handsome ridge vent. The ribs looked great from the street. Inside, I found can lights without covers, a bathroom fan discharging into the attic, and a two-inch gap along an unsealed top plate that ran nearly thirty feet. We sealed those leaks, installed an insulated vented duct to the exterior, and air-sealed around the chimney with sheet metal and fire-rated sealant. The next winter, the icicles were gone. Same shingles, same ridge vent, different air movement.
Window retrofits: insert replacements versus full-frame swaps
Insert replacements slide into the existing frame, which saves siding and interior trim, but they often leave air and water problems untouched. If the old frame is out of square, rotted at the sill, or never flashed properly, an insert is a bandage. On the other hand, if the frame is sound and square, an insert can be perfectly acceptable with one caveat: pay attention to the perimeter air seal.
When I specify inserts, I inspect the sill and jambs for sound wood, check for plumb and level, then plan a two-stage seal. At the exterior, a backer rod and sealant joint must be compatible with the cladding and flexible enough to move with seasonal changes. At the interior, I want a clean gap for low-expansion foam or mineral wool, then continuous backer rod and sealant behind the interior stop. Caulking over trim is not an air seal. The seal must bridge the frame to the interior finish layer, not just sit on top of paint.
A full-frame replacement exposes the rough opening and allows proper flashing, shimming, insulating, and integration with the wall WRB. It costs more and requires more skill. In climate zones with wind-driven rain or for homes with known water intrusion, this route reduces risk. Roofing contractors sometimes coordinate with the window team here, especially when wall cladding ties into roof step flashing at dormers. That junction should be planned, not guessed at with a tube of caulk from a ladder.
Choosing contractors who understand the building as a system
Price matters, but scope and sequence are what keep you from paying twice. I look for roofers and window installers who can speak the language of air barriers, furring, tapes and primers, and pressure testing. They will not be the cheapest, and that is a good sign.
Here is a short, targeted checklist to use when interviewing roofing contractors or window installers:
- Ask for a description of their air-sealing process, not just product names. Listen for details like backer rod, low-expansion foam, taped WRB seams, and liquid-applied flashings. Request blower door testing before and after, or at least a smoke-pencil demonstration around sample areas. Confirm who is responsible for sealing bath fans, range hoods, and attic access points, and how those will be detailed. Get pictures of similar jobs that show opened assemblies, not only finished exteriors. Make sure warranty language covers installation details, not only shingle or window manufacturer defects.
Searches for phrases like roofing companies or roofing contractor near me will return a long list. Sort them by who treats your home as a system rather than a collection of products. The best roofing company for your house is the one that prevents problems you cannot see, not just the one that installs fast.
Air sealing without creating indoor air quality problems
Tightening a home demands forethought about ventilation and combustion safety. Seal first, then ensure fresh air on your terms. In a tight house, exhaust-only bath fans can depressurize rooms with atmospherically vented water heaters or furnaces, especially in small mechanical closets. If you are cutting air leakage in half, consider upgrading to sealed-combustion appliances or adding make-up air and a balanced ventilation strategy.
I aim for kitchen ventilation at 150 to 300 cfm ducted outside, with a make-up air plan for hoods above 400 cfm. Bath fans should be quiet enough to use and move 80 to 110 cfm with short, smooth duct runs that terminate at a roof cap or exterior wall cap, not into soffits. In very tight homes, a small heat recovery ventilator can run continuously at 40 to 80 cfm, keeping humidity and CO2 levels steady without a big energy penalty.
If you still have a naturally drafted water heater, test worst-case depressurization after air sealing. A qualified technician will use a manometer, run exhaust devices, and confirm that the flue pulls properly under typical and worst conditions. Do not skip this, and do not assume the old appliance will behave the same after you change the pressure balance.
The details that separate careful work from cosmetic fixes
I judge exterior work by the things most people never see. A roof edge with a continuous bead of sealant under the drip edge at the rake, starter course locked to the eave with proper underlayment laps, and step flashing interwoven with siding at sidewalls shows a crew that cares. At skylights, I want factory kits installed over fresh underlayment, then a secondary air seal at the interior shaft with foam board and tape or foam that ties to the drywall. In cold climates, that shaft should be insulated to R-10 or more to prevent condensation.
At windows, shims should be placed at the hinge points to carry load, not randomly stuffed. Screws should hit structure, not only vinyl fins. The reveal should be consistent within a sixteenth of an inch. Sill pans should slope to daylight. If a crew tells you they do not need sill pans because they caulk well, ask them who pays for the rot repair when the caulk fails. Every sealant joint fails at some point. Good assemblies are designed to drain even when something goes wrong.
Managing the tricky intersections: dormers, penetrations, and masonry
The hardest parts of the shell are the places where different materials meet. A dormer cheek that meets a main roof and ties into lap siding invites both air and water if rushed. I have solved more than a few drafts by opening those corners, finding bare sheathing, and rebuilding the transition with a belt-and-suspenders approach: taped sheathing panels, peel-and-stick at the plane break, pre-bent kickout flashing at the roof-to-wall, and then siding. At the interior, I tie the drywall air barrier to framing with a bead of acoustic sealant before trim returns go on.
Masonry meets its own rules. Window replacements in brick require backer rod and a high-performance sealant that can handle movement. A too-stiff caulk cracks at the first freeze-thaw cycle. I specify a homemasters.com Roofing companies joint that is twice as wide as it is deep, sized to allow compression. On older brick, you cannot rely on mechanical fasteners alone without planning for shimming and load distribution. A good installer knows how to anchor without spalling the masonry.
At roof penetrations for solar arrays, satellite mounts, or new vents, prefabricated flashing helps, but the air seal happens below the deck. A mount that finds a rafter with lag screws but leaves an unsealed bore at the sheathing still leaks air. I want sealant at the shank interface and a butyl or gasketed base under the flashing, then a patch of underlayment that laps correctly. When I plan a solar job with a roof replacement, we mark out array zones and pre-install blocking to avoid a forest of random penetrations later.
The role of materials: tapes, membranes, and foams that last
Not all tapes are equal. A cheap housewrap tape clings to the roll more than the wall in winter. When I need a durable bond, I choose pressure-sensitive adhesives designed for sheathing, and I apply them with a roller after priming if the substrate is dusty or cold. For irregular openings, a liquid-applied flashing shines. It fills the corners at sills and creates a continuous, flexible pan that bonds to wood and masonry.
Foams matter too. Closed-cell spray foam can air-seal and insulate in one step, but it requires trained applicators and a plan for vapor control. One or two inches at the roof deck with a fluffy insulation underlayer can create a safe hybrid approach in many climates. At window gaps, I still prefer low-expansion one-part foam or mineral wool with a gasketed interior seal. I avoid stuffing fiberglass in those narrow gaps. It does not stop air movement on its own, and once it gets dirty with air leakage, you can smell it on a humid day.
Sealants should be chosen for joint size, UV exposure, and movement. Silicone adheres well to glass and many metals but can be hard to paint. Polyurethane bonds aggressively to wood and masonry and takes paint, but it can be finicky in damp conditions. High-quality silyl-terminated polyether hybrids offer flexible, paintable performance for many exterior joints. Indoors, an acoustic sealant behind trim and at drywall seams to framing can remain flexible for decades and makes a meaningful difference at the pressure boundary.
Sequencing work so you do not undo it
The right order prevents waste. If you are planning a roof replacement and window upgrades within a two-year window, settle the roof first if you have active leaks or failing shingles, but carve out time for attic air sealing before the new roof goes on. When decking is accessible, air sealing is easier and cheaper. If windows are your top priority and the roof is sound, handle the windows first and coordinate any wall WRB tie-ins at roof step flashing lines with your roofer so you do not trap water or create reverse laps.
Painters and drywallers can undo beautiful air sealing work with a careless cut at the attic hatch or by prying off gaskets during trim work. Put up clear notes for trades, and if you are your own general contractor, walk the site before and after each crew. Blue tape and a Sharpie cost a few dollars and save hours of repair.
Numbers you can reasonably expect
Every house differs, but patterns emerge. In cold and mixed climates, tightening a leaky home by 25 to 40 percent on a blower door often cuts heating energy by 10 to 25 percent. In hot-humid regions, air sealing can knock 5 to 15 percent off cooling loads and significantly improve humidity control, which makes a home feel better at a higher thermostat setting. Window replacements deliver comfort gains at the glass and frame, but the perimeter seal contributes disproportionately to the savings in drafty homes. When a homeowner tells me their new windows did little for bills, I ask about the installation. If the installer only used a single exterior caulk bead, savings will disappoint.
Roofing-driven savings come when sealing the attic plane and duct penetrations accompany new shingles. Expect smaller utility line items but bigger comfort shifts: fewer hot rooms in summer, less temperature swing at night, and quieter interiors on windy days. The payback lives not just in energy, but in durability. Dry roof sheathing lasts. Dry top plates resist mold. Sealed ducts deliver the air you pay to condition.
When to call a specialist and how to verify results
Not every crew has a blower door, and not every job needs one, but measurement builds confidence. An energy auditor can collaborate with your roofer and window installer to identify priority leaks with infrared imaging and pressure diagnostics. In many areas, utilities subsidize audits, and some roofing contractors partner with auditors to deliver a bundled service.
If a blower door is not in the budget, you can still verify critical seals. On a windy day, hold a smoke pencil or even a stick of incense near window trim, electrical outlets on exterior walls, attic hatches, and bath fan housings. If the smoke streams steadily, a path exists. At windows, check the inside corners at the sill and jamb where trim meets the frame, then the head next. At the attic, lift insulation lightly to peek at the top plates and see whether seams at drywall are sealed or simply dusted with loose fill.
Photographic documentation helps. Ask your roofing contractor for shots of sealed top plates, boxed can lights, and duct connections before insulation is blown. For windows, request images of sill pans, shims, and backer rod before the final trim goes on. Good companies are proud to show their process. Roofing contractors who talk about air sealing and show finished details earn trust fast.
Budgeting smartly: where dollars do the most work
If I had a modest budget and a leaky house, I would start at the roof plane and the window perimeters rather than jump straight to new equipment. Here is a straightforward order of operations that stretches dollars:
- Seal attic leaks and duct penetrations, then top off insulation to code-minimum or better. Correct bath and kitchen venting to the exterior with rigid or semi-rigid duct and sealed joints. Tune up or replace the worst-performing windows, with careful perimeter air sealing on every unit. Address knee walls, attic hatches, and fireplace or chimney surrounds with proper air and thermal barriers. Commission HVAC to confirm airflow and refrigerant charge, then consider right-sizing at the next replacement rather than oversizing now.
On many projects, this path delivers the best mix of comfort, moisture control, and lower bills. If a full window package or a high-end roof replacement is in your plan, keep these priorities inside those larger scopes rather than bolt them on later.
The bottom line
Windows and roofs are more than finishes. They are where physics meets craftsmanship. Air sealing transforms both into active parts of your comfort system. The roof keeps weather out, but the attic plane controls pressure and moisture. The glass blocks radiant load, but the window perimeter decides whether you feel a draft on the couch. Pick roofers and window installers who show you their plan to manage air and water at the edges. Whether you are sifting through roofing contractors, debating the best roofing company for a complex roof replacement, or comparing bids from window firms, weigh the details. That is where the savings hide, and that is where homes become quieter, drier, and easier to heat and cool.
