Roof warranties are a valuable investment that protect your home and offer peace of mind. Provided by professional roofing companies, these warranties act as a safeguard against unexpected repair costs. However, not all homeowners are aware of the actions that could void these warranties, potentially costing them thousands down the line.
Roof warranties come in various lengths and coverage levels, often ranging from 20 to 50 years. But no matter how comprehensive your warranty may be, it can become void if certain guidelines aren’t followed. Here are the top five mistakes that can void your roofing warranty and what you can do to avoid them.
1. Installing New Shingles Over Old Ones
Layering new shingles over existing ones might seem like a cost-effective shortcut, but it can backfire. This practice traps heat, compromises ventilation, and prevents roofers from inspecting the underlayment and sheathing. Most manufacturers and contractors strictly advise against this, and doing so can result in a voided warranty.
2. Poor Roof Ventilation
Inadequate ventilation is one of the most overlooked yet critical aspects of a roofing system. Without proper airflow, heat and moisture can build up in your attic, causing mold growth and premature aging of the shingles. Unfortunately, damage due to poor ventilation is rarely covered by warranties.
3. Drilling Holes for Antennas or Satellite Dishes
Installing satellite dishes or antennas may seem harmless, but the process involves drilling into the roof’s surface, which can compromise its integrity. These modifications often create leak points and are a common reason for voided warranties. Always consult your roofer before making such additions.
4. Pressure Washing the Roof
While it may seem like a quick solution for moss or algae, pressure washing is too harsh for most roofing materials. The intense water pressure can strip granules from shingles, weaken sealants, and lead to premature deterioration — all of which can nullify your warranty coverage.
5. Mixing Components from Different Roofing Systems
Using roofing components from multiple manufacturers may seem convenient but is generally discouraged. Each system is designed to work cohesively with its own components. Mixing brands can disrupt this synergy, potentially undermining performance and leading to the voiding of your roofing warranty.
