Your roof is the most expensive thing on your house that you almost never look at. You walk under it every single day and never give it a thought until there's a stain on the ceiling. In this episode of Thoughts from the Crawl Space, Jamie Miller pulls back the curtain on the one system most homeowners ignore until it fails, breaking down what's actually up there and why it matters long before a leak shows up.

A roof is not just shingles. It's decking, underlayment, roof covering, flashing, and ventilation all working together. We cover the difference between three-tab and architectural shingles, how long each type really lasts, and the outside factors that quietly add or subtract years from your roof's life, from sun orientation and overhanging trees to attic ventilation and sloppy installation. You'll also learn why the small stuff, like a cracked vent boot or a single backed-out nail, causes more leaks than dramatic storm damage.

Whether you're buying a home or just want to know how many years you have left over your head, this episode gives you a practical framework for understanding, inspecting, and planning for your roof. Look up, ask better questions, and start planning before year 20, not after the water shows up.

● A roof is a system, not just shingles. It includes decking, underlayment, covering, flashing, and ventilation, and every part has to do its job to keep water out.

● Three-tab asphalt shingles last roughly 15 to 20 years, while architectural (dimensional) shingles run closer to 25 to 30, though 20 to 25 is more realistic in practice.

● Sun orientation, shade trees, attic ventilation, and installation quality all shift a roof's lifespan, for better or worse. Overhanging branches trap moisture and accelerate wear.

● Vent boots, the rubber collars around plumbing pipes, typically fail in 10 to 12 years, well before the shingles. One small crack can leak down a vent pipe and into the attic unseen.

● Small problems cause big leaks: backed-out nails, lifted shingles after windstorms, failed chimney flashing, and caulk used in place of proper flashing.

● Walking a roof reveals far more than binoculars from the ground, but it depends on pitch, age, moisture, and safety. As a homeowner, never walk your own roof.

● Two layers of shingles is the practical maximum and not best practice. Roofing over an existing roof can cut the new shingles' life by an estimated 40 percent.

● Old water stains in the attic tell a history even when the leak is currently dry. An inspector is only seeing a snapshot in time.

● Keep gutters clean, trim overhanging branches, scan ceilings and the attic after storms, know your roof's age, and budget before a leak forces the decision.

The first 90 degree day always exposes the weak link in a home. You walk to the thermostat, drop it to 72, and an hour later it still reads 78. The unit is running. It just isn't winning. In this episode of Thoughts from the Crawl Space, Jamie Miller breaks down how residential air conditioning actually works and how to make sure that frustrating scenario isn't yours this summer.

The big idea is simpler than most people expect: an air conditioner does not make cold air, it moves heat out of your house. From split systems and mini splits to geothermal heat pumps, Jamie explains the parts that do the work, why an oversized unit can actually hurt you by skipping dehumidification, and what a home inspector looks for on every cooling system, including the data plate, tonnage, temperature split, clearance, refrigerant lines, electrical disconnect, and condensate drain.

You'll also learn the warning signs that your unit is in trouble, the repair-or-replace math behind older R22 systems, and a practical six-step action list to keep your AC running efficiently. Whether you're buying a home this summer or protecting the one you already own, the age and condition of the air conditioner is something worth understanding before the heat arrives.

● An air conditioner doesn't create cold air, it moves heat out of the house. The refrigerant absorbs heat inside and releases it outside, which is why warm air blows off the outdoor unit while it runs.

● Most Indiana homes use a split system, with the condenser outside and the evaporator coil, or A-coil, inside on or near the furnace. Mini splits and geothermal heat pumps are other options for cooling and heating.

● A bigger unit is not better. Oversized systems cool fast, shut off, and never run long enough to dehumidify, leaving the home clammy and wearing out the compressor with constant on-off cycling. A slightly undersized unit that runs longer is healthier.

● Inspectors read the data plate for age and capacity. In the model number, find the value roughly divisible by 12 and divide by 12 to get tonnage. One ton cools roughly 800 to 1,000 square feet.

● A proper temperature split between return and supply air runs about 14 to 22 degrees, with 15 to 20 ideal. Too little can mean low refrigerant, too much can point to a dirty, slow blower motor.

● Keep at least a couple of feet of clearance around the outdoor unit so it can breathe. The larger suction refrigerant line should be insulated end to end to prevent sweating, dripping, and damage.

● Every system needs an outdoor electrical disconnect within sight, usually no more than six feet away, so a technician has full control of the power. Keep the condensate drain clear, or backed-up water will pool or shut the unit down.

● Warning signs include constant running without reaching temperature, weak or warm air at the vents, ice on the refrigerant line, water around the furnace, new grinding or rattling noises, short cycling, and a sudden spike in the electric bill.

● Older R22 systems are expensive to recharge since the refrigerant was phased out, so a major leak often makes replacement smarter. Most units last 15 to 20 years, longer with good maintenance.

Spring in the Midwest brings melting snow, shifting soil, and a laundry list of small problems that can turn into expensive repairs if left alone. In this episode of Thoughts from the Crawl Space, we walk through a practical seasonal checklist covering roofs, gutters, grading, foundations, crawl spaces, decks, plumbing, and pest prevention so you can catch issues early and protect your biggest investment.

Key Takeaways

● Winter leaves clues. Start your inspection outside, looking for missing or curling shingles, granule loss in gutters, and interior staining that points to ice damming.

● Gutters and downspouts do heavy lifting. Keep them clean, sealed at the joints, sloped correctly, and extended four to six feet away from the foundation.

● Grading is the number one exterior defect on home inspections. Soil should slope away from the house roughly one inch per foot for the first six feet.

● Roughly 95 percent of basement water problems come from roof and yard runoff, so controlling water at the surface prevents most foundation headaches.

● Check foundation cracks annually. Hairline cracks are normal curing cracks, but horizontal or widening cracks deserve a professional evaluation.

● Reopen crawl space vents that were closed for winter, look for standing water, mold growth, torn vapor barriers, and wet insulation.

● Walk the exterior for failed caulk, peeling paint, wood rot, and air leaks around windows that drive up heating and cooling costs.

● Inspect decks for loose railings, rotting boards, and lifted fasteners. Most deck collapses trace back to poor ledger attachment.

● Test your sump pump by pouring a bucket or two of water into the pit, service the HVAC, change the furnace filter, and seal any gaps where pipes or vents enter the home.
