Understanding When Your Roof Needs Replacement

At Cran-Marsh Inc., we’ve spent over 50 years helping property owners throughout New England, Cape Cod & The Islands recognize the critical signs that indicate roof replacement is necessary. Age remains the primary factor, with most asphalt shingle roofs lasting between 20 to 30 years depending on quality, installation, and environmental conditions. Beyond age, we look for telltale indicators like widespread granule loss, multiple missing shingles, sagging areas, daylight visible through roof boards, and persistent leaks despite repairs. Our experience as a trusted contracting team has taught us that proactive replacement prevents costlier structural damage.

Weather patterns in New England, including Cape Cod and the Islands create unique challenges for roofing systems. Heavy snow loads, ice dams, summer heat, and coastal storms accelerate deterioration. We evaluate each roof’s condition comprehensively, examining not just visible shingles but also underlayment, decking, flashing, and ventilation systems. Our GAF Master Elite Certification ensures we identify issues that less experienced contractors might overlook, providing honest assessments about whether repair or replacement makes more financial sense.

Our Comprehensive Replacement Process

Our family owned and operated approach means we handle every replacement project with meticulous attention to detail. We begin with thorough structural inspection, checking rafters, trusses, and decking for damage or rot. Any compromised wood gets replaced before new roofing installation begins. We then install high-quality ice and water shield barriers, particularly crucial around valleys, eaves, and penetrations where leaks commonly develop. Our CertainTeed Master Shingle Applicator certification demonstrates our commitment to manufacturer-approved installation methods.

Proper ventilation installation distinguishes professional replacement from basic re-roofing. We calculate exact ventilation requirements based on attic square footage, ensuring balanced intake and exhaust airflow. This prevents moisture buildup, ice dams, and premature shingle deterioration. As a Velux 5 Star Skylight Specialist, we also expertly integrate skylights during replacement projects, creating brighter interior spaces while maintaining watertight seals. Our systematic approach includes protecting landscaping, daily cleanup, and magnetic sweeps for nails, reflecting our “Big Enough to Get the Job Done. Small Enough to Care” philosophy.

Material Selection and Long-Term Value

Choosing appropriate roofing materials significantly impacts longevity, energy efficiency, and property value. We guide customers through options ranging from traditional three-tab shingles to architectural and designer varieties. GAF Timberline HDZ shingles remain popular for their durability and wind resistance ratings up to 130 mph. CertainTeed Landmark series offers exceptional color retention and algae resistance. For commercial properties, we install TPO, EPDM, and modified bitumen systems engineered for flat and low-slope applications.

Energy-efficient options have gained tremendous traction as utility costs rise. Cool roof shingles with reflective granules reduce attic temperatures by up to 20%, lowering cooling expenses. We also install solar-ready systems that accommodate future panel installation without compromising roof integrity. Impact-resistant shingles qualify for insurance discounts while providing superior protection against hail damage. Our expertise helps customers balance upfront costs with long-term savings and performance.

Planning Your Replacement Project

Successful roof replacement requires careful planning and coordination. We provide detailed project timelines, typically completing residential replacements within two to four days depending on size and complexity. Our process includes:

• Initial consultation and inspection: We assess current conditions, discuss material preferences, and provide transparent pricing
• Permit acquisition: We handle all necessary building permits and HOA approvals
• Material ordering and delivery: Premium materials arrive on-site exactly when needed
• Weather monitoring: We schedule work during favorable conditions to ensure proper installation
• Final inspection: Thorough quality checks confirm proper installation before project completion

Budget considerations extend beyond material costs. We help customers understand total investment including tear-off disposal, decking repairs, ventilation upgrades, and flashing replacement. Many insurance policies cover replacement costs when damage results from covered perils. We work directly with insurance adjusters, providing detailed documentation and advocating for appropriate coverage. Our honest, competent approach means we never recommend unnecessary work while ensuring all essential components receive proper attention.

Financing options make replacement accessible when unexpected needs arise. We offer flexible payment plans that spread costs over manageable timeframes. Federal tax credits may apply when installing qualifying energy-efficient materials. Our commitment to building trust and exceeding expectations means we present all financial options transparently, helping customers make informed decisions aligned with their budgets and long-term property goals.
