KLM is an Owens Corning Preferred Contractor for asphalt shingle roofing. We also install standing-seam metal and flat/low-slope roofing.
The roof is the one part of your home that can't afford to be average. Siding and roofing failures can both allow concealed damage. A roofing failure hides inside your walls, your attic, and your ceilings — often for years before it becomes undeniable, and by then the damage is expensive.
Most homeowners think about their roof twice: when they buy the house and when something goes wrong. We'd rather you think about it once — carefully, with someone who can tell you exactly what you have, what it has left, and what the right replacement looks like for your home. That's what a consultation with KLM looks like.
WHAT KLM INSTALLS
Asphalt shingles are a widely used roofing material, and for good reason — they perform reliably across Pennsylvania's climate. They are available in a wide range of profiles and colors. Service life depends on the shingle, installation, roof design, exposure and maintenance.
The difference between a roof that lasts and one that does not isn't always the shingle. It's what goes under it. Proper underlayment, ice and water shield extended well past the eave line, ridge ventilation, and precise flashing at every connection — chimney, skylight, pipe boot, valley — are where roofs fail or hold. KLM designs deliver in these areas.
We install Owens Corning shingles and carry Preferred Contractor status. Owens Corning offers several limited warranty options with specific contractor, product, installation and registration requirements. Total Protection Roofing System® describes a coordinated roofing system; it is not a promise that every component or claim receives the same coverage. During your consultation, we'll walk through the shingle options and warranty tiers, explain what each actually covers, and help you land on the right choice for your budget and the home.
One thing we won't do: install new shingles over an existing layer when the decking underneath needs to be evaluated. A layover that hides failing sheathing or inadequate flashing is a short-term solution that becomes a long-term problem. We do it right the first time.
KLM also offers flat and low-slope roofing, an established part of our roofing services. A shallow roof needs a system suited to its slope, drainage, penetrations and adjoining walls. It should not be treated as a steep-slope shingle roof with fewer courses.
The assessment should identify the existing assembly, condition of the deck, drainage outlets and transitions. The proposal should specify the replacement system and how those details will be addressed. Ask about the appropriate option for your addition, porch, garage or other low-slope area during the consultation.
Standing-seam metal is an option for homeowners considering a long-term roofing investment. The metal roofing product, manufacturer and warranty will be identified in the proposal. Why it's particularly well-suited to this area. Pennsylvania and New Jersey weather patterns put roofs through a full range of stress every year — heavy snow loads, hard freezes, the ice damming that forms when heat escapes an under-insulated attic and refreezes at the eave, spring rain, summer heat, and UV exposure that degrades conventional materials from the top down. Standing-seam performance depends on the panel system, coating, attachment, roof geometry and installation. Snow and ice may slide from a metal roof; entrances, walkways and lower roofs may need a designed snow-retention strategy. Metal panels move with temperature changes, so the attachment and detailing must accommodate that movement.
The concealed fastener difference. Standing-seam systems use raised seams and concealed attachment to reduce exposed fastener penetrations across the panel field. The exact fastening method varies by system, and penetrations, transitions and edge details still require careful installation and inspection.
The honest financial case. A standing-seam roof can have a higher initial cost than asphalt shingles. Compare the actual systems, installation scope, expected maintenance and ownership period. Long service life can be a reason to consider metal, but the least-expensive option over time and any resale benefit depend on the property and assumptions.
Summer efficiency. Solar reflectance depends on the selected color and coating. Cooling effects also depend on the roof assembly, insulation, ventilation, climate and the rest of the home; no savings amount should be assumed from the material alone.
Low maintenance, long integrity. Standing-seam roofs still need appropriate inspection and care. Keep drainage paths clear and have damaged coatings, flashing or sealants assessed. Algae discoloration on asphalt shingles is generally cosmetic; it should not be equated with moss growth or treated as proof that a roof is failing.
We'll walk you through the comparison between systems during your consultation and give you real numbers for both options on your home. The choice is yours — we just want you making it with accurate information.
When KLM strips a roof, we look at what's underneath before anything new goes on. The roof deck — the plywood or OSB sheathing the shingles fasten to — is the structural foundation of the whole system. Softness, delamination, rot from years of slow moisture intrusion: these have to be dealt with before new material goes over them, or you're paying full price for a roof that's already compromised.
We also assess attic ventilation. An under-ventilated attic traps heat in summer (which degrades shingles from the inside out) and moisture in winter (which rots decking and breeds mold). Ventilation must suit the actual roof and attic assembly; where a vented assembly is appropriate, intake and exhaust need to work together. If your current system is undersized, we'll tell you and give you options.
What we find underneath sometimes affects the scope and cost of the project. When it does, we stop, show you what we found, and get your approval before proceeding. No surprises on the invoice.
1. Free consultation and inspection We assess your current roof up close — not from the driveway. We're looking at shingle condition, flashing integrity, decking, ventilation, gutters, and any visible signs of moisture intrusion. You'll leave the conversation with a clear picture of what you have and what the options are.
2. Detailed proposal Your proposal covers material, system, warranty, and scope — including any known prep work. As with all our projects, if you want to make decisions on certain details as the project takes shape, we accommodate that. Any changes to scope are documented and priced before they're executed.
3. Tear-off and deck inspection The existing roof comes off. We inspect the deck and address anything that needs repair before new material goes on. You're informed of anything discovered.
4. Installation by a dedicated roofing crew Like all phases of our work, roofing is handled by a crew trained specifically for it. Underlayment, ice and water shield, field installation, ridge detail, and every piece of flashing is done to specification.
5. Cleanup and final walkthrough Magnet sweeps for fasteners, debris cleared from the property, gutters checked. We walk the finished roof with you and register your manufacturer warranty before we close out the project.
Check the tear-off scope, deck repairs, underlayment, flashing, edge details, ventilation, disposal and cleanup as well as the visible roof covering. Chimneys, skylights, valleys and changes in pitch can make two roofs of similar area very different projects.
Agree on how concealed deck damage will be photographed, priced and approved. The selected roof covering must be compatible with the slope and assembly. Coordinate related siding work or a portico at roof-to-wall transitions.
A manufacturer warranty has eligibility rules, covered causes, limits and exclusions. Any contractor workmanship commitment is a separate document. Review the exact tier offered, registration requirements and transfer conditions with the proposal. See Owens Corning’s warranty information.
That depends on the cause, the insurance policy and the exact product warranty. Some manufacturer warranties include conditional wind-related blow-off coverage; that does not mean every storm, hail impact or leak is covered. Ask the insurer and manufacturer about the applicable terms before assuming reimbursement.
Not necessarily. Algae staining alone is not the same as a failed shingle. Loose or missing material, leakage, deteriorated flashing and the condition of the roof assembly need assessment. Follow the manufacturer’s care instructions rather than using aggressive cleaning that could damage the surface. Owens Corning explains algae resistance and staining here.
Size, roof complexity, material, access, repairs and weather affect timing. The project plan should explain the sequence, protection of exposed areas, cleanup and communication. A one- or two-day promise should not substitute for an assessment of your actual roof.
