Friendly, Personable Service We respond promptly to all customer inquiries and provide an accurate timeline of service (weather permitting). Our friendly, personable service includes supplies and installation of all materials. There’s no need for a down payment; you pay us after the job is done to your satisfaction. Professional From Start to Finish Whether you need a new roof, a re-roofing or just repairs, you’ll get a professional job from start to finish. We use only our own employees – no sub-contractors. Guaranteed Workmanship Whether you have leakage problems or need someone knowledgeable in roof ventilation (what type and how much ventilation should be used), DeJager Roofing guarantees only the best workmanship and excellent customer service, with conscientious clean-up after the job is done.
