I cannot write a description of "Shelter Distribution" based on the website text provided. The text you've shared appears to be from QXO, a roofing products supplier, not from a company called Shelter Distribution. The content repeatedly references roofing products, QXO branding, and roofing-related services, with no mention of "Shelter Distribution" or McKinney anywhere in the material. To write an accurate description for your referral directory, I would need website text that actually belongs to Shelter Distribution.
