Low-Slope & Flat Roof Solutions

Many Seattle area homes have porch additions or low-slope sections that standard shingles can’t protect. We install the right membranes for those areas—TPO/PVC or self-adhered modified bitumen—and integrate them cleanly into adjacent shingle fields for a watertight transition.

Moss, Needles & Preventive Maintenance

Seattle roofs battle moss, pine needles, and wind-driven rain. Our maintenance plans include gentle debris removal, preventative treatments, sealant refresh at flashings, and a roof/attic checkup. Routine care extends roof life and catches small problems before they become leaks.

Attic Ventilation & Moisture Control

Proper intake and exhaust ventilation reduces moisture, helps prevent winter condensation, and supports manufacturer warranties. We balance soffit intake, baffles, and ridge ventilation to meet spec—and verify airflow during your final walkthrough.

Skylights & Roof Accessories

We replace aging skylights during re-roofs, install new solar tubes, upgrade bath fan roof caps, and add drip edge and gutter aprons to protect fascia. All penetrations are flashed to manufacturer standards for a long-term seal.

Insurance & Real-Estate Inspections

Buying or selling? We provide photo-rich roof inspections and written reports. If wind or tree damage triggers a claim, we’ll document the scope, meet with the adjuster as requested, and propose like-kind materials that satisfy policy guidelines.

“MBA Construction Corp are not just roofers or siders; they’re builders and can accommodate houses in any condition.
I recently purchased an older home that had been neglected for decades. What started out as residing project with window and door replacement, turned in to a remediation project that required an expertise you simply won’t find with your average siding company. After pulling off the old siding it turned out that in addition to wood rot, the house didn’t even have plywood in place. They also discovered old construction materials that were simply dumped into crawl spaces decades ago. Of course it’s unnerving as a homeowner when discoveries like this are made, but the Barrera brothers would calmly explain how they would remedy the issue at each turn. I watched the team methodically and skillfully repair the many issues they encountered throughout the course of the project. Ultimately the team transformed my home over the course of five weeks. In addition to the siding, windows and doors they replaced a decrepit old wood deck with a brand new Trex deck, which really smartened up the front entrance. In addition to being skilled craftsman, Jose, Alex and Tony are great guys. We have the utmost trust in their guidance and work quality. They also treat your home with a level of care you seldom experience with other contractors. Going forward, I plan on going with MBA Construction Corp for all of my exterior and interior home projects.”
