Our Roof Underlayment Installation Process

Every roof coating project starts with a thorough condition assessment to identify moisture issues, surface damage, and coating compatibility. We then apply premium silicone or acrylic coatings using professional spray equipment that ensures even coverage and proper adhesion. Our three-stage quality control process includes surface preparation, coating thickness testing, and final inspection—all backed by our 20-year unlimited guarantee.

Free Roof Inspection & Material Assessment

Before coating begins, our Keystone technicians conduct a comprehensive roof inspection to determine the best coating solution for your property. We assess surface material, age, existing protective layers, pre-existing damage, moisture levels, and structural integrity. This evaluation identifies repairs needed before coating and helps us recommend the optimal coating type—whether silicone for superior UV resistance or acrylic for cost-effectiveness. We measure the entire roof area, document problem zones, and evaluate drainage systems and weather exposure. You receive a detailed assessment report with transparent pricing and coating recommendations backed by our 20-year guarantee.

Professional Waterproof Membrane Installation

Keystone’s professional coating process delivers maximum roof protection through proven application methods. Our certified team first power-washes the roof surface to remove all debris, moss, and contaminants. We then repair any existing damage, seal vulnerable areas, and apply primer where needed. Using commercial-grade spray equipment, we apply your chosen coating system in uniform layers that cure into a seamless, monolithic barrier against moisture, UV rays, and temperature extremes. Most residential projects complete in 1-2 days with minimal disruption. Call 087 223 4228 to schedule your coating service across Cork.

Quality Control & 20-Year Warranty Guarantee

Quality control is non-negotiable on every Keystone coating project. We perform moisture readings before application, monitor weather conditions to ensure optimal curing temperatures, and test coating thickness at multiple points to meet manufacturer specifications. Our documentation includes surface preparation photos, coating batch numbers, and application conditions. We verify proper adhesion and coverage before considering any project complete. Every coating application includes our 20-year unlimited guarantee plus 365 Emergency Assist Service. Contact 087 223 4228 for details on our quality standards.

When Should You Replace Your Roof Underlayment?

Professional roof coating prevents expensive replacements when applied at the right time. Keystone has helped hundreds of Cork property owners identify optimal coating windows. Our 20-year guarantee covers every project. You need roof coating when you notice visible wear (fading, chalking, surface deterioration), when your roof membrane reaches 5-7 years without damage, or when energy bills increase due to poor heat reflection. Schedule a free inspection when any signs appear. Our team uses advanced diagnostic tools for accurate assessments, backed by 365 Emergency Assist Service.

What to Expect During Installation

Keystone’s coating process prioritizes safety, speed, and minimal disruption. We begin with safety perimeter setup and fall protection systems for our certified team. Weather monitoring ensures application occurs in optimal dry conditions (10-30°C). Most residential projects complete in 1-3 days. Our efficient work practices mean you can continue daily activities while we work—no need to vacate your property. Cleanup is thorough, leaving your property in pristine condition.

Frequently Asked Questions About Roof Underlayment

How Long Does a Typical Roof Underlayment Installation Take to Complete?

We typically complete roof underlayment installations within 1-2 days, though this can vary based on your roof's size and complexity. We'll always give you a specific timeline after evaluating your property's unique requirements.

Can Roof Underlayment Be Installed in Wet Weather Conditions?

We don't recommend installing roof underlayment in wet conditions. It's unsafe for our workers and can compromise the material's effectiveness. We'll gladly schedule your installation when weather conditions are dry and suitable.

What's the Average Lifespan of Different Types of Roof Underlayment Materials?

We typically see synthetic underlayments lasting 20-30 years, while traditional felt paper lasts 12-20 years. Premium rubberized underlayments can last up to 50 years with proper installation and maintenance. Let's discuss your needs.

Is It Possible to Install Underlayment Over Existing Roofing Materials?

While it's technically possible, we don't recommend installing underlayment over existing materials. We'll remove old materials first to guarantee proper installation and prevent moisture issues. Call us at 021 202 8298 for professional assessment.

How Much Does Roof Underlayment Affect the Overall Cost of Roofing?

We typically find that underlayment costs make up about 5-10% of your total roofing budget. While it's a relatively small portion, it's essential for protecting your home and shouldn't be compromised on quality.
