Frequently Asked Questions

Answers to common questions about home improvement projects, skylight systems, and finding quality contractors.

About Skylights & Natural Light

What size skylights should I choose for my room?

The right skylight size depends on your room’s dimensions and how much natural light you want. Generally, skylights should be no more than 5% of floor area in rooms with plenty of windows, or up to 15% in rooms with limited natural light. A professional skylight contractor like M&M Skylights can assess your specific space and recommend the ideal size for maximum light and energy efficiency.

How can I prevent skylight leaks?

Prevention starts with professional installation. Proper flashing—the weatherproof seal around your skylight—is the single most critical element in preventing leaks. According to building guidelines and roofing standards, installation must follow specific techniques to ensure complete waterproofing. I highly recommend working with experienced professionals who understand these requirements rather than attempting DIY installation.

What are energy-efficient skylights?

Modern energy-efficient skylights use specialized glazing technologies and coatings that minimize heat loss in winter and heat gain in summer. Look for skylights with ENERGY STAR certification, which meet strict U-Factor and Solar Heat Gain Coefficient (SHGC) requirements. These certified products can significantly reduce your home’s heating and cooling costs while providing the natural light benefits you want.

How long do skylights typically last?

Quality skylights with proper installation usually last 20-30 years. The lifespan depends on the skylight material, installation quality, and environmental factors like weather exposure. Regular maintenance and prompt repair of any leaks extends the life significantly. If your skylights are showing age or performance issues, professional contractors can assess whether repair or replacement is the better option for your home.

Finding Quality Contractors

What should I look for in a skylight contractor?

Look for contractors with demonstrated expertise in skylight installation and repair. They should understand roofing integration, waterproofing requirements, and industry standards. Ask for references from previous projects, verify insurance and licensing, and get detailed quotes explaining their installation process. Professional contractors will take time to answer your questions and explain why they recommend specific approaches.

How do I compare contractor estimates?

Get detailed written estimates from multiple contractors. Compare not just the price, but what’s included in their service—materials quality, installation process, warranties, and after-service support. Don’t automatically choose the lowest price; consider the contractor’s experience, reputation, and commitment to quality. Sometimes paying more ensures better craftsmanship and fewer problems down the road.

What warranty should I expect?

Quality contractors typically offer warranties on both materials and labor. Material warranties often cover 10-20 years depending on the product, while workmanship warranties should cover at least 5 years. A reputable contractor stands behind their work and provides clear documentation of what’s covered. Ask about warranties upfront and get everything in writing before work begins.
