It depends on the extent of the damage. Our process starts with a thorough roof inspection to identify the leak's source, which is often around flashing, vents, or damaged shingles common in our coastal climate. Many leaks can be resolved with a precise roof repair. However, if we find widespread wear, moisture in the decking, or failing underlayment—common issues in older SF homes—a roof replacement or reroofing might be the more cost-effective, long-term solution. We'll provide a clear assessment and explain all your options.

In San Francisco, clogged or faulty gutters are a major culprit. When gutters overflow, water cascades down your siding and can seep behind walls or into the roof edge, saturating insulation and leading to mold. Our gutter cleaning, repair, or replacement services ensure water is channeled away from your home properly. For complete protection, we often recommend combining this with our moisture control installation, which creates a barrier to protect your home's structure from the damp conditions common in the Bay Area.

A standard roof repair addresses a specific point of failure, like replacing shingles. Waterproofing is a systemic solution. For persistent moisture issues, especially on flat roofs, around skylights, or in basements, a waterproofing installation or repair creates a continuous, sealed membrane. This is crucial in San Francisco for areas prone to pooling water or driven mist. We also install and repair sump pumps to actively remove groundwater. Think of waterproofing as an added layer of defense against our pervasive dampness, working alongside a sound roof structure.
