Our Issaquah Roofing and Exterior Home Services
We offer a full suite of exterior services, each delivered with the same commitment to quality and customer satisfaction.

Roof Installation
Protect your investment with a professionally installed new roof designed to withstand the demanding Pacific Northwest climate. We specialize in a variety of materials, including long-lasting metal roofing and high-performance architectural shingles from Malarkey, ensuring your home is ready for any weather. Our expert installation team follows manufacturer specifications precisely, guaranteeing optimal performance and maximizing your warranty coverage.

Roof Repairs
From minor leaks to extensive storm damage, our team provides prompt and reliable roof repairs that address both the symptoms and the root cause of the problem. We conduct thorough inspections to diagnose issues with damaged shingles, faulty flashing, poor ventilation, or structural concerns before recommending the most cost-effective solution. Our repair work is designed to seamlessly integrate with your existing roof, using quality materials that match your current system and extend its overall lifespan.

Siding
Transform your home’s curb appeal and weather resistance with professionally installed new siding that enhances both beauty and performance. We offer expert installation of top-quality materials, including James Hardie fiber cement, natural cedar, durable vinyl, and modern metal siding options. Each material is selected to improve your home’s energy efficiency, protect its structure from moisture damage, and reduce long-term maintenance requirements. Our skilled installers ensure proper moisture barriers, precise alignment, and attention to architectural details that make your siding installation both functional and visually stunning.

Gutters
Properly functioning gutters are essential in the PNW, where heavy rainfall can quickly overwhelm inadequate drainage systems. We install, repair, and maintain high-quality gutter systems, including seamless aluminum K-style and fascia gutters that effectively manage rainwater and protect your foundation, landscaping, and siding from water damage. Our installations include proper pitch calculations, secure mounting, and strategic downspout placement to ensure optimal water flow away from your home.

Decks
Create the perfect outdoor living space with a custom-built deck designed specifically for your lifestyle and property. We design and construct beautiful, durable decks using premium materials like cedar, composite, and hardwood that are built to withstand Issaquah’s wet climate and provide years of enjoyment. Our deck building process includes careful site assessment, structural engineering for proper load-bearing, and waterproofing solutions that prevent moisture damage to your home.

Painting
A professional exterior paint job revitalizes your home’s appearance and provides a crucial layer of protection against moisture, UV damage, and weathering. We use premium paints from trusted brands like Sherwin-Williams, Benjamin Moore, and Behr, selected specifically for their durability in the Pacific Northwest climate. Our meticulous preparation includes power washing, scraping, sanding, caulking, and priming to ensure optimal paint adhesion and longevity. The result is a stunning, long-lasting finish that enhances your curb appeal.

Roofing Insights for Issaquah, WA
Located at the foothills of the Cascades, Issaquah presents unique roofing challenges. The increased rainfall and shade from the surrounding mountains create a perfect environment for moss and algae growth, making material choice critical. Homes in the area range from historic properties in Olde Town needing careful preservation to the modern, master-planned communities of the Issaquah Highlands and Talus, which demand contemporary, high-performance systems. Homeowners here value long-term performance, energy efficiency, and materials that enhance property value in a competitive market. We recommend architectural shingles with built-in moss inhibitors, like Malarkey’s Vista or Legacy lines, or standing seam metal roofs for their superior durability and water-shedding capabilities.
