Freddy López — Your Roofer, Your Neighbor
Born and raised near Lynn, Freddy started FJM Construction with one simple belief: homeowners deserve a contractor who shows up, tells the truth, and does the job right the first time. After 13+ years in the field, that belief hasn't changed.
When you call FJM, Freddy himself picks up. He personally attends every estimate — because no two homes are the same, and he never wants a customer making a big decision without hearing it straight from the expert.

Our Comprehensive Maintenance Checklist
Shingle Condition Review
We inspect every shingle for curling, cracking, granule loss, and age-related wear that signals upcoming failure.
Flashing & Sealant Check
Chimneys, skylights, and vents — the #1 source of leaks. We inspect and re-seal any compromised flashing.
Gutter & Drainage Inspection
Clogged gutters cause water backup and ice dams. We verify proper drainage and clear any visible blockages.
Attic Ventilation Assessment
Poor ventilation causes moisture buildup and premature shingle failure. We verify your system is working correctly.
Photo Report
You receive a documented photo report of every issue found — with our honest recommendation: repair, monitor, or replace.
Pre-Winter Priority Scheduling
Annual program members get priority fall scheduling before the first freeze — so your roof is ready.
Roof Repairs — Fast, Honest & Done Right
From a single missing shingle to a persistent leak — we diagnose the real problem and fix it. No inflated scopes, no pressure to replace when a repair will do the job.
No Leak Too Small, No Damage Too Complex
Active Leak Diagnosis
We find where water is actually entering — not just where it's dripping. Real source identification before any repair begins.
Missing & Damaged Shingles
Wind-blown, cracked, or storm-damaged shingles replaced with matching materials so the repair blends seamlessly.
Flashing Replacement
Chimney, valley, and pipe boot flashing repaired or replaced to stop the most common leak entry points.
Ice Dam Damage Repair
After ice dams tear up shingles and damage eaves, we repair the area and install ice & water shield to prevent recurrence.
Storm Damage Assessment
After severe weather, we document all damage thoroughly — including for insurance claim support if needed.
Honest Repair vs. Replace Advice
We'll always tell you if a repair makes financial sense — or if replacement is actually the smarter move. We never oversell.
Siding Replacement — Transform Your Home's Exterior
New siding protects your home's structure from moisture, pests, and extreme temperatures — while dramatically boosting curb appeal. FJM delivers a flawless install with materials built to last.
Everything Included in Our Siding Replacement
Full Old Siding Removal
We remove all existing siding, inspect the sheathing underneath, and replace any rotted areas before installing new material.
Weather-Resistant House Wrap
A continuous moisture barrier is installed under new siding to block infiltration and improve energy efficiency.
Wide Style & Color Selection
Vinyl, fiber cement, wood — we help you choose siding that matches your home's character and withstands New England weather.
Precision Installation
Every panel installed level, every corner flashed, every trim piece fitted — the details that separate a great job from one that fails.
Trim, Soffit & Fascia
We don't stop at the panels. Trim boards, soffit, and fascia updated for a fully finished, cohesive exterior look.
Complete Site Clean-Up
All old siding hauled away, area swept clean, and a final walkthrough with you before we call it done.
Siding Maintenance — Protect Your Home Year-Round
Regular maintenance prevents moisture intrusion, mold growth, and premature failure — saving you thousands in repairs down the road.
What Our Siding Maintenance Includes
Full Exterior Inspection
We walk every inch of your home's exterior checking for gaps, cracks, warping, and any area where water could enter.
Caulking & Sealing
Joints, seams, and penetrations re-caulked with high-grade exterior sealant to hold through freeze-thaw cycles.
Mold & Mildew Treatment
Visible mold or algae growth cleaned and treated so it doesn't spread and accelerate siding degradation.
Window & Door Trim Check
The area around every opening inspected — the most common place water finds its way inside a home.
Written Assessment Report
You receive a clear written report of what we found — what's in good shape, what to monitor, and what needs attention soon.
Annual Program Available
Sign up for our annual plan and we'll reach out each year when it's time — so you never have to worry about scheduling.
Siding Repair — Cracked, Rotted & Storm-Damaged Panels
Don't replace what only needs repair. We assess your siding honestly and fix what's broken — matching materials so every repair is seamless.
We Fix All Types of Siding Damage
Storm & Impact Damage
Hail dents, tree branch strikes, and wind-blown debris repaired quickly before water infiltrates the wall cavity.
Rot & Moisture Damage
Rotted panels and underlying sheathing removed and replaced completely — not just painted over — so the problem doesn't return.
Warped & Buckled Panels
Improper installation or heat expansion causes buckling. We diagnose the root cause and re-install affected sections correctly.
Around Windows & Doors
The most leak-prone areas on any home. We replace compromised trim, re-flash, and re-seal to stop moisture intrusion.
Color-Match Replacement
We source matching panels or use premium materials that blend so well you won't see where the repair begins.
Honest Repair vs. Replace Advice
If repairs exceed 30% of the total siding surface, a full replacement may be more cost-effective. We'll tell you honestly.

Roofing Transformations
Siding Transformations
Built on Trust. Proven by 13 Years of Results.
FJM Construction was founded with one mission: give Greater Boston homeowners a roofing and siding contractor they can actually trust — one who shows up, communicates clearly, and does the job right.
From the Job Site Up
Freddy López didn't start FJM Construction behind a desk. He started on rooftops — learning the trade from the ground up, nail by nail, shingle by shingle. After years working for other contractors, he saw the same problems over and over: upselling customers on replacements they didn't need, cutting corners on materials, leaving job sites a mess, and never picking up the phone.
In 2011, he founded FJM Construction Inc to do it differently. Today, 13+ years and 500+ completed projects later, the business has grown almost entirely through referrals — a track record Freddy is deeply proud of.
He still attends every estimate personally. He still picks up the phone himself. And he still does a final walkthrough on every job before calling it done.
📞 Call Freddy — (781) 731-4757The 6 Values That Drive Every FJM Project
🤝 Radical Honesty
We tell you what your roof or siding actually needs — even if that means recommending a $200 repair instead of a $12,000 replacement.
📞 Personal Availability
Freddy's number is on every card. He picks up, calls back, and keeps you updated at every stage — no voicemail black holes.
🏅 Premium Materials Only
We use GAF architectural shingles and name-brand exterior products — because great installation fails if the materials don't hold up.
