frequently asked questions

If the roof has fewer than 10 years of life left, yes. Removing and reinstalling an array to reroof underneath it later costs far more than doing the roofing work first, while the panels are still in boxes.

Usually attic ventilation, not the air conditioning. Trapped heat under the roof deck radiates down through the ceiling all afternoon, and adding balanced intake and exhaust vents often drops upstairs temperatures noticeably without touching the cooling equipment itself.

Watch for granules collecting in gutters, shingles that curl or lift at the edges, cracked or slipped tiles, rusted flashing around chimneys and vents, and any ceiling stain that darkens after rain. Daylight visible in the attic is urgent.

It rarely returns the full amount at sale, but it removes a major objection and helps a listing move faster. Buyers and inspectors treat an aging roof as leverage, and a documented replacement takes that leverage off the table.

Flashing is the metal that seals joints where a roof meets a wall, chimney, valley, or vent. It fails through corrosion, thermal movement, dried sealant, and incorrect layering, which is why most leaks begin at these transitions rather than in open field areas.

Sagging points to a structural issue rather than a surface one. Water-damaged sheathing, undersized or broken rafters, added weight from multiple roofing layers, and long-term moisture in the framing are the usual culprits behind a visible dip.

Check the ground for displaced shingles or tile fragments, then scan the roof with binoculars for lifted edges, exposed underlayment, and bent flashing. Inside, look for fresh attic daylight and any damp spots near the chimneys or roof vents.

Underlayment is the water-resistant membrane installed between the deck and the visible roofing material. Shingles and tile shed most water, but the underlayment stops whatever gets past them, which makes it the layer that truly keeps interiors dry.

Yes, provided the repair addresses the actual entry point rather than the nearest visible damage. Existing stains do not fade on their own, so repaint after the area dries fully and watch it through the next several rains.

Considerably. A dark surface can run 50 degrees hotter than a reflective one on a summer afternoon, and much of that heat reaches the attic. Lighter or cool-rated colors keep upstairs rooms measurably easier to cool through the afternoon.

Not by themselves, though every skylight adds a penetration that needs correct flashing and periodic attention. Older units with failing seals and site-built curbs cause most of the trouble, while modern factory-flashed kits perform reliably for decades.

They perform very well here, offering long service life, strong reflectance, and excellent fire resistance for hillside properties. The main considerations are matching the profile to your architecture and finding a crew experienced with standing-seam detailing rather than asphalt shingles.

They need more of it. Low-slope roofs drain slowly, so debris, ponding water, and failing seams cause damage far faster. Drains and scuppers need regular clearing, and seams, curbs, and terminations should be inspected at least twice every year.

Drip edge is metal trim installed along eaves and rakes that directs runoff into the gutter instead of behind it. Current code requires it on most new roofing work, and it prevents a great deal of fascia rot.

Close the openings they use. Eave gaps, open tile ends, damaged soffit panels, and unscreened vents all offer easy access, and sealing them with proper closures and screening removes the entry without blocking the airflow your attic needs.

Yes. Winters in Montclair, CA, leave plenty of workable weeks, and Kaliber Roofing schedules around forecast rain. Torch-applied and adhesive-based systems need dry, moderate conditions, so those installations get planned around the weather far more carefully.

Sudden events such as storm damage, wind uplift, or a fallen limb are typically covered, while gradual wear, neglect, and age related failure are not. Documentation from an inspection performed soon after the event strengthens any claim considerably.

Common signs of poor work include exposed nail heads, missing drip edge, sealant used in place of flashing, uneven course lines, and inadequate ventilation. Kaliber Roofing finds several of these on plenty of the Montclair, CA, homes we inspect.

Thermal movement is the usual cause. Framing, sheathing, and roofing all expand through the heat of the day and contract sharply after sunset, and the sounds you hear are those materials shifting slightly against their fasteners and against each other.
