William Mackay Roofing Before & After Photos

Before and After: TPO Roof Replacement in Washington, D.C. Before: The old roof located in N. W DC showed significant signs of wear, including cracks, punctures, and visible ponding water. The aging materials contributed to leaks during heavy rain, leading to potential water damage inside the home. Additionally, the roof's energy efficiency was compromised, resulting in higher utility bills due to heat absorption. After: The new TPO roof gleams with a bright, white surface that reflects sunlight, significantly improving energy efficiency. The installation features seamless seams that enhance durability and prevent leaks. With a smooth, clean appearance, the roof not only protects the home but also boosts its curb appeal. Homeowners can now enjoy peace of mind, knowing their roof is ready to withstand D.C.'s weather while reducing energy costs.

Before and After: Modified Bitumen Roof Replacement in NE Washington, D.C. Before: The existing modified bitumen roof was showing signs of significant deterioration. There were multiple areas of cracking and blistering, leading to water infiltration and leaks during heavy rains. The seams were weakened, and some sections had noticeable pooling, which posed a risk for further water damage to the underlying structure. Additionally, the roof's dark color absorbed heat, contributing to increased cooling costs in the summer months. The overall aesthetic was lackluster, with debris accumulation and fading. After: Following the replacement, the new modified bitumen roof presents a fresh, clean look with a lighter color that enhances energy efficiency by reflecting sunlight. The installation features robust, properly sealed seams that ensure superior waterproofing, eliminating the risk of leaks. The new roof system includes additional insulation, providing better thermal performance and reducing energy costs significantly. With a smooth, uniform surface, it's now easy to maintain and keep free of debris. Overall, the upgraded roof not only protects the home more effectively but also elevates its curb appeal, providing peace of mind to the homeowners.
