What We Do | Cambridge Roofing & Maintenance Roofing Services
Cambridge Roofing & Maintenance handles every roofing job from a single-shingle repair to a full commercial re-roof. Here's what we do in Cambridge.
Roof Replacement
GAF Timberline HDZ with the full GAF Roof System qualifies your home for the Golden Pledge warranty. That's 25 years on workmanship and 50 years on materials, including algae protection. We install Cobra Snow Country ridge vent with external baffle, FeltBuster synthetic underlayment meeting ASTM D226 Type II equivalent, and Starter Match Pro starter strip. Every component is GAF-approved and inspection-documented.

Roof Repair
Most roof leaks in Cambridge come from one of five places: pipe boots, step flashing at walls, valley flashing, damaged shingles, or failed seals around skylights. We find the actual source. Not just the drip point in your ceiling. And fix it right. Water travels along rafters and sheathing before it drips, so the leak location and the damage location are often 10 feet apart.

Storm Damage Repair
After a major storm in Cambridge, we mobilize quickly. Emergency tarping within 24 hours to prevent secondary water damage. Then a full damage inspection once conditions allow. We use drone photography on larger commercial roofs to document everything the adjuster needs.

New Roof Installation
We install new roofs on new homes, additions, detached garages, carports, and covered patios. Material options include asphalt architectural shingles, metal standing seam, metal corrugated, and flat membrane systems. We help you choose based on your budget, aesthetic preference, and the specific demands of your Cambridge climate.

Metal Roofing
Metal roof repairs are usually sealant failures at transitions, loose panels from improper installation, or rust spots on older galvanized systems. Our Cambridge crew repairs all metal types. Not every issue needs a full replacement. Sometimes a sealant touch-up or panel re-securing solves it.

Shingle Roofing
GAF Timberline HDZ. The best-selling shingle in North America. With StrikeZone nailing area for consistent fastener placement. Class A fire rating per UL 790, Class 4 impact resistance per UL 2218 (when installed in the GAF Roof System), and Class H wind rating per ASTM D7158 (130 mph). We install Timberline in the full GAF system to qualify for Golden Pledge warranty: 25-year non-prorated workmanship plus 50-year materials with WindProven limited wind warranty (no max speed). That warranty is why we recommend GAF for most Cambridge homes.

Flat Roofing
EPDM (rubber roofing) has a 50+ year track record as a flat roofing membrane. We install fully adhered EPDM with taped or glued seams over polyiso insulation. It's a great option for Cambridge building owners who want proven performance at a lower cost than TPO or PVC.

Commercial Roofing
We install Carlisle SynTec and Firestone TPO membrane systems in 60-mil and 80-mil thickness over minimum R-25 polyiso insulation (more in climate zones requiring it). Seams hot-air welded at 900°F+ and tested with a seam probe. Fully adhered systems for wind uplift zones per FM I-90 or I-120. Mechanically attached for re-roofs over existing insulation. NRCA member, trained per manufacturer specifications.

Gutter Installation
Clogged gutters cause fascia rot, soffit damage, and foundation erosion from concentrated water runoff. That's not a marketing scare tactic. We see the damage on every other gutter replacement in Cambridge. Properly sized gutters with adequate downspout capacity move water away from the house. We calculate capacity using rainfall intensity data for Cambridge: roof area x pitch factor x rainfall rate in inches per hour. Standard 5" K-style handles 5,520 square feet of effective roof area.

Roof Inspection
Our inspection covers the roof and the attic. From the attic, we check for daylight through the roof deck, moisture stains on rafters, mold on sheathing, and ventilation function. Problems in the attic often indicate roof issues that aren't visible from the surface.

Emergency Roof Repair
Emergency tarping is step one. Stop the water. We secure heavy-duty poly tarps over the damaged area using 2x4 nailer boards attached to the deck. Once the immediate threat is contained, we schedule the permanent repair within 48-72 hours.

Skylight Installation
VELUX FS (fixed) and VS (vented) skylights installed with EDL flashing kits for shingle roofs. The multi-step flashing integrates with the surrounding shingle courses per IRC R903.2. We frame the curb with doubled 2x8 or 2x10 lumber (depending on rafter depth), install ice and water shield membrane around the entire curb perimeter, then set the skylight with factory sealant before weaving step flashing into the field. Top headwall flashing tucks under the upslope shingle course. Bottom sill pan diverts water onto the downslope shingles. Zero exposed sealant joints. Mechanical flashing only.
