Wood shake roofing can be compatible with rooftop solar racking, but it requires careful consideration and proper installation to avoid damaging the roof or voiding warranties. Wood shakes are natural, irregular, and prone to cracking or splitting, especially when penetrated for mounting solar racks. Because they can absorb moisture and are more flammable than other materials, ensuring a watertight seal around mounting points is crucial. It’s important to use mounting hardware specifically designed for wood shake roofs or to install solar racks with minimal penetration methods. Simple DIY checks include inspecting the shakes for any signs of damage, rot, or loose pieces that could be worsened by adding weight or drilling. If the roof is older or showing wear, or if you notice any soft spots or moss growth, it may not be in great shape to support solar racking without some repairs first.
Calling a professional roofer or solar installer with experience on wood shake roofs is a smart move before proceeding. Ask them how they plan to attach the racking without compromising the integrity of the shakes and whether they will use flashing or other weatherproofing techniques to prevent leaks. Also, inquire if their work will keep your roofing warranty intact, as some manufacturers may void coverage if the roof is penetrated inappropriately. Good questions to ask are: “What specific hardware and sealing methods will you use for mounting on wood shake?” and “How do you ensure the roof stays watertight and safe from damage over time?” Getting clear answers will help you make a confident decision and protect both your roof and investment in solar energy.
