Ice dams form when heat escaping through your East Lansdowne roof melts snow near the ridge, and that water refreezes at the cold eaves. The ice forces meltwater under shingles and into your home. Prevention requires proper attic insulation and ventilation — both of which we assess during every Delaware County inspection.

Roofing materials expand and contract with temperature cycles. Over years, this movement works sealants loose at flashing laps and creates fastener-loosening forces. Maintenance inspections catch the early signs of thermal movement failure before they become water infiltration points.

Register the manufacturer warranty promptly after installation, keep documentation of all maintenance visits and repairs, and use licensed contractors for any repair work. Some warranties require specific maintenance intervals — check your warranty documentation.

Industry data consistently shows that every dollar spent on proactive roof maintenance prevents three to five dollars in reactive repair costs. The ROI improves as roofs age, since the failure modes that maintenance prevents become increasingly expensive to remediate.

Core roof maintenance includes annual inspections, gutter cleaning twice a year, resealing pipe boots and flashing joints showing early wear, clearing debris from valleys and low-slope sections, and trimming branches that overhang the roof surface.

Gutters should be cleaned at minimum twice a year — once after spring pollen and budding season, and once after fall leaf drop. Homes with heavy tree coverage may need three to four cleanings annually.

Gutter cleaning is a manageable DIY task for most homeowners with a stable ladder, proper footwear, and attention to safety. If the gutters are high, the pitch is steep, or the home is multi-story, professional cleaning is the safer choice.

Gutter guards are covers or inserts designed to keep debris out of gutters while allowing water through. Quality micro-mesh guards significantly reduce cleaning frequency. No gutter guard eliminates cleaning entirely, but good ones extend the interval substantially.

Zinc sulfate or copper-based solution applied to the roof surface kills moss effectively. Rinse gently after treatment — don't pressure wash, which removes granules. Trimming overhanging branches that deposit organic material and shade the roof reduces recurrence.

Pressure washing asphalt shingles removes granules and can void warranties. Low-pressure soft washing with appropriate cleaning solutions is the safe method for cleaning algae and biological growth. Tile and metal roofs have different protocols.

Algae-resistant shingles with zinc or copper granules are the most effective prevention at installation. On existing roofs, zinc strips installed at the ridge release zinc oxide during rain events that inhibits algae. Annual application of diluted zinc sulfate solution treats existing growth.

After. Roofing work deposits debris — granules, old flashing material, fasteners — that will clog gutters if they aren't cleaned after the project. Build post-project gutter cleaning into any scope that involves significant surface work.

A roof maintenance plan is an annual or biennial service agreement with a roofing contractor covering inspection, minor repairs, gutter service, and documented condition reporting. Plans extend service life and ensure early identification of developing issues.
