Shaddai Home Improvement installs, replaces, and repairs roofs across Cambridge, from the steep Victorian roofs of Old Cambridge to the two family and three decker stock of North Cambridge and Cambridgeport. Twenty five years working on the architectural variety and tight lot conditions of Cambridge roofing.
Cambridge Historical Commission reviews roofing material on designated properties. We submit documentation before starting work on listed homes.
Cambridge two and three families require coordination across multiple units. We work with property owners and tenants to minimize disruption during roofing.
Cambridge Victorian roofs with complex geometry create severe ice dam conditions. We install proper ice and water shield and assess attic ventilation.
Cambridge has substantial flat roof inventory on two families and additions. We install TPO and modified bitumen on low slope sections.
Cambridge roofing works across a housing stock dominated by late Victorian and early twentieth century construction. Old Cambridge between Harvard and Porter Square has substantial Victorians with complex roof geometry including multiple gable lines, dormers, bay windows with small roof sections, and decorative cornice details that complicate material tear off and replacement. Two families throughout Cambridgeport and North Cambridge have simpler gable roofs but often have flat roof rear additions that require different materials. The mix of pitched and flat sections on a single building is common in Cambridge.
The Cambridge Historical Commission reviews exterior changes including roofing material on designated properties. The application requires documentation of the proposed material, color, and profile. Architectural shingles in appropriate colors typically pass commission review without significant objection on most Cambridge properties. Roofing material on designated properties requires commission approval before any work begins. We submit complete documentation on the first review cycle to minimize delays on time sensitive projects.
Cambridge two and three family buildings require roofing coordination across multiple units. Tenants need advance notice of the work schedule. Noise and debris affect multiple households. Dumpster placement on Cambridge streets is permitted and often competed for. We work with property owners and tenants to minimize disruption during the project. Early start times comply with Cambridge noise ordinances and the work schedule gets communicated to all affected parties before the crew arrives.
Cambridge roof installation on Victorian and two family homes starts with a full deck inspection after the tear off. The existing shingles hide what is underneath and the deck condition determines the quality of the finished installation. Victorian roofs often have skip sheathing or board sheathing rather than plywood or OSB. We assess the existing deck and recommend the appropriate solution for each specific substrate.
Ice and water shield installation on Cambridge roofs covers the full eave, every valley, all penetrations, and transitions at walls and dormers. Victorian roofs with complex geometry have more valleys and transition points than simpler gable roofs. Each one is a potential ice dam entry point. We cover all of them with ice and water shield installed over the entire vulnerable area rather than just the minimum required by code.
CertainTeed architectural shingles are our standard specification on Cambridge residential roofs. The product handles the Massachusetts climate, carries manufacturer warranty coverage, and provides the visual profile that works on most Cambridge residential architecture. We register every installation for warranty tracking and follow CertainTeed installation specifications exactly because warranty coverage requires proper installation technique.
Cambridge two family and three decker buildings frequently have flat roof rear additions that require different materials than the main pitched roof. TPO membrane on flat sections provides twenty year performance with heat welded seams that eliminate the leak points at seam overlaps. Modified bitumen provides reliable performance on flat sections at lower cost than TPO but with shorter expected service life. We recommend the appropriate material based on the drainage situation, the existing substrate, and the homeowner's budget.
Drainage on Cambridge flat roof sections is a chronic problem because many flat roof additions were built without adequate slope toward drains. Water ponds on flat sections with inadequate drainage and eventually penetrates even intact membranes at seams and penetrations. We assess drainage slope on every flat roof project and add drainage improvements where needed before installing new membrane. Fixing drainage at installation time costs less than returning later for repairs caused by inadequate drainage.
Combined roofing projects on Cambridge properties often involve both pitched main roofs and flat rear additions on the same building. We coordinate both sections in one project, handling the transitions and flashing details that determine long term water tightness at the intersection of the two different systems. Doing both sections at once produces better integration than separate contractors handling separate sections without coordination.
Cambridge winters create ice dam conditions on roofs with inadequate ventilation or insulation. Victorian roofs with complex geometry have more potential ice dam formation points than simple gable roofs. Each valley, dormer, and transition is a potential ice dam entry point. We assess attic ventilation and insulation as part of every Cambridge roofing estimate and address deficiencies when the scope includes replacing the roof system.
Cambridge Inspectional Services requires building permits for full roof replacement. We pull the permit, schedule the inspection, and receive sign off as part of every full replacement project. The Cambridge Historical Commission review adds time to the permitting process on designated properties. We start both processes simultaneously to minimize total project delay.
Energy code compliance requirements in Cambridge have increased over time. The Massachusetts Stretch Energy Code, which Cambridge has adopted, adds insulation and air barrier requirements beyond the base code. When roofing work includes attic access, we can coordinate insulation improvements that contribute to energy code compliance. The combination of roofing and insulation work done together is more cost effective than doing them in separate phases.
Professional roofing on Cambridge homes protects the structure, prevents ice dam damage, and delivers the energy performance Massachusetts winters demand.

Whether you own an Old Cambridge Victorian or a North Cambridge two family, the roof protects the structure from the moisture and ice that Cambridge winters deliver.
Our Work
The Cambridge Historical Commission reviews exterior changes including roofing material on designated properties. Architectural shingles in appropriate colors typically pass review. We submit complete documentation before starting work on listed homes.
We work with property owners to give tenants advance notice of the roofing schedule. Early start times comply with Cambridge noise ordinances. The work schedule gets communicated to all affected parties before the crew arrives. We minimize disruption while completing the work efficiently.
We install TPO membrane, EPDM, and modified bitumen on Cambridge flat roof sections depending on drainage situation, existing substrate, and budget. We assess drainage slope on every project and address inadequate drainage before installing new membrane.
Cambridge Victorian roofs with complex geometry create multiple ice dam entry points at valleys, dormers, and transitions. We install ice and water shield across all vulnerable areas and assess attic ventilation. Proper ventilation prevents ice dam formation by keeping the roof surface uniformly cold.
A typical Cambridge single family runs 1 to 2 days. Victorian homes with complex geometry take 2 to 3 days. Two and three family buildings take 2 to 4 days depending on the number of sections. Historical Commission review adds permitting time on designated properties.
