Problem 1: Pool Cover Damage
Pool cover damage is the most common winter cover problem, affecting 30 to 40 percent of pool covers annually. Damage includes tears from sharp objects or tree branches, rips from wind stress or improper installation, holes from animals or debris, seam separation from age or stress, and UV degradation from prolonged sun exposure. Cover damage allows debris to enter pools, reduces insulation effectiveness, permits algae growth from sunlight penetration, and ultimately requires cover replacement costing $200 to $2,000 depending on pool size and cover type.
Causes of Cover Damage
Heavy snow and ice accumulation creates excessive weight causing material stress and tearing. Sharp objects including tree branches, tools, or pool equipment puncture or tear cover material. Wind catches improperly secured covers causing flapping and stress that leads to rips. Animals including squirrels, raccoons, and birds claw or chew through covers. UV radiation degrades cover material over multiple seasons making it brittle and prone to tearing. Poor quality covers or improper installation create stress points that fail under winter conditions.
Prevention Strategies
Inspect covers monthly for damage including small tears, holes, or weak spots. Remove tree branches and sharp objects from the pool area before installing covers. Secure covers properly using adequate water bags (15 to 25 for typical pools) or safety cover springs at proper tension. Trim overhanging tree branches that could fall on covers during storms. Use quality covers designed for winter use that resist UV degradation and weather damage.
Repair Solutions
Repair small tears and holes immediately using cover repair kits like Rola-Chem Ultra Swimming Pool Safety Cover Repair Patch or vinyl repair patches like Boxer Underwater Glue and Material Repair Kit. Clean the damaged area with rubbing alcohol. Cut patches 2 to 3 inches larger than the damage with rounded corners. Apply adhesive to both patch and cover per kit instructions. Press firmly working from center outward to eliminate air bubbles. Allow 24 hours curing time before exposing to weather. Repair kits cost $10 to $30 and prevent damage from spreading.
Problem 2: Water Accumulation
Water accumulation on solid pool covers is a persistent problem causing cover sagging, excessive weight stress, ice dam formation, mosquito breeding, and potential cover collapse. Rain, snow melt, and condensation accumulate on covers creating pools of standing water that can weigh hundreds of pounds.
Why Water Accumulation is Problematic
Excessive weight from accumulated water stresses cover material and attachment points potentially causing tears or separation. Sagging from water weight allows covers to sink into pools contacting water and reducing effectiveness. Ice dams form when accumulated water freezes preventing drainage and creating additional weight. Standing water provides mosquito breeding habitat creating nuisance and health concerns. Prolonged water exposure degrades cover material reducing lifespan by 1 to 2 years.
Prevention with Cover Pumps
Install automatic cover pumps like the Coverblast Pool Winter Cover Pump Attachment that activate when water depth reaches 1/4 to 1/2 inch. Position pumps in the lowest point of the cover where water naturally collects. Direct discharge hoses away from the pool area to prevent water from flowing back onto the cover. Check pumps monthly to ensure they are operating properly and remove debris from intake screens. Cover pumps cost $50 to $150 and prevent water damage costing $200 to $1,000.
Manual Water Removal
If automatic pumps are not available, manually remove water using a submersible pump or siphon. Check covers after rain or snow melt and remove accumulated water promptly. Never allow water accumulation to exceed 2 to 3 inches depth as this creates excessive weight. For above ground pools, ensure air pillows like the 4 foot winterizing air pillow are properly installed to create a peak that sheds water.
Problem 3: Algae Growth
Algae growth during winter occurs when sunlight penetrates through mesh covers or gaps in solid covers, creating conditions favorable for algae establishment. Winter algae growth turns water green or black, stains pool surfaces, consumes winterizing chemicals, and requires extensive spring cleanup costing $200 to $500 in chemicals and labor.
How Algae Grows in Winter
Mesh covers allow 10 to 20 percent sunlight penetration providing energy for algae photosynthesis. Gaps or holes in solid covers allow sunlight beams that promote localized algae growth. Inadequate winterizing algaecide fails to prevent algae spore germination. Mild winter temperatures above 50°F allow algae to thrive even in dormant pools. Debris on covers decomposes providing nutrients that feed algae growth.
Prevention Strategies
Use solid safety covers that block 100 percent of sunlight preventing algae photosynthesis completely. Ensure covers are properly secured with no gaps or holes allowing sunlight penetration. Add winterizing algaecide like Omni Winter Care Algaecide or Applied Biochemists Wintertrine Algaecide at 2 to 4 times normal maintenance dose for 3 to 6 months protection. Use comprehensive winterizing kits like Winter Care Pool Closing Kits that include proper algaecide dosing.
Cover Maintenance for Algae Prevention
Remove debris from covers monthly to prevent organic matter from decomposing and providing algae nutrients. Inspect covers for tears or gaps and repair immediately. Keep covers clean and properly secured throughout winter. For mesh covers, accept that some algae risk exists and plan for spring shock treatment and brushing to address any growth that occurs.
Problem 4: Cover Collapse
Cover collapse from excessive snow weight is a serious problem in areas with heavy snowfall. Collapsed covers sink into pools allowing debris entry, damaging cover material, potentially damaging pool equipment, and requiring cover replacement costing $200 to $2,000.
Snow Load Dangers
Snow weighs 7 to 20 pounds per cubic foot depending on moisture content (wet snow weighs more than dry snow). A 20x40 foot pool with 12 inches of wet snow accumulation carries 10,000 to 13,000 pounds of weight. This excessive weight causes covers to sag into pools, tears cover material at stress points, separates cover attachments, and can damage pool coping or walls if covers sink completely.
Snow Removal Procedures
Remove snow when accumulation exceeds 6 to 8 inches to prevent excessive weight. Use a soft broom, foam snow rake, or pool cover snow removal tool (never use metal shovels that can tear covers). Start from the center of the cover and work toward edges to avoid concentrating weight in one area. Push or sweep snow off the cover rather than lifting to minimize stress on cover material. Remove snow in multiple sessions rather than waiting for heavy accumulation.
Cover Support Systems
Install cover support systems or air pillows under covers to provide structural support and prevent sagging. For in ground pools, use inflatable cover supports or rigid support poles placed strategically under the cover. For above ground pools, ensure air pillows are properly sized (covering 25 to 40 percent of pool surface) and inflated to 60 to 70 percent capacity. Support systems cost $30 to $150 and prevent collapse damage costing $500 to $2,000.
Problem 5: Cover Maintenance
Inadequate cover maintenance reduces cover lifespan from the typical 5 to 7 years to just 2 to 3 years, requiring premature replacement and wasting your investment. Proper maintenance extends cover life, ensures effective protection, and prevents problems during winter.
Regular Cleaning
Clean covers monthly during winter to remove debris, leaves, and dirt. Use a soft broom or leaf blower to remove dry debris. For stubborn dirt or stains, use pool cover cleaner like GLB Cover Care Pool Cover Cleaner or mild detergent with a soft brush. Rinse thoroughly with water and allow to dry. Never use harsh chemicals, pressure washers, or abrasive brushes that can damage cover material.
End of Season Storage
When removing covers in spring, clean them thoroughly before storage. Spread covers out and scrub both sides with mild detergent and soft brush. Rinse completely and allow to dry thoroughly (both sides must be bone dry to prevent mold). Fold covers loosely using accordion style folding to prevent sharp creases. Store in a cool, dry location away from direct sunlight, chemicals, and rodents. Use storage bags or bins to protect from dust and pests.
Inspection and Repair
Inspect covers before installation each fall for damage including tears, holes, worn areas, or UV degradation. Repair minor damage before installation using patch kits. Replace covers showing extensive damage, multiple tears, or significant UV degradation. Document cover age and condition to plan for eventual replacement. Most covers last 5 to 7 years with proper care but should be replaced when damage becomes extensive.
Proper Installation
Install covers correctly following manufacturer instructions. Ensure covers are sized properly for your pool (extending beyond edges on all sides). Secure covers adequately using proper number of water bags (15 to 25 for typical pools) or safety cover springs at correct tension. Verify covers are centered and evenly distributed. Proper installation prevents stress points that lead to premature failure.
